Description

Technical Field

[0001] This disclosure relates to the field of tunnel construction technology, and in particular to a shield tunneling system. Background Technology

[0002] In tunnel construction, it is necessary to transport materials from the outside of the tunnel to the inside, from the inside of the tunnel to the outside, and to inject grout into the gaps between the tunnel's surrounding rock and the tunnel segments to cooperate with the shield tunneling equipment to complete the tunnel construction. However, at present, the material transportation is mostly intermittent, and it is not possible to efficiently process or transport the materials transported from the inside of the tunnel to the outside in a timely manner. At the same time, the grout in the gaps between the tunnel's surrounding rock and the tunnel segments also takes a long time to solidify. This results in a long construction period and low construction efficiency for shield tunneling in tunnels, which in turn increases the cost of shield tunneling in tunnels. Summary of the Invention

A third continuous conveying system continuously or uninterruptedly conveys the second material from the material pool to the second material handling system for continuous external transport or processing. A grouting auxiliary system injects a mixture of third and fourth materials into the tunnel's surrounding rock and the gaps between the tunnel segments to accelerate the solidification of the third material within these gaps. This effectively shortens the conveying time of the first and second materials, the processing time of the second material, and the solidification time of the third material, thereby significantly reducing the construction period of the tunnel boring machine (TBM) and improving its efficiency and cost.

[0083] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0084] like Figure 1 and Figure 8 As shown in the embodiments of this disclosure, a tunnel boring machine (TBM) system is proposed, including a first continuous conveying system 1, a second continuous conveying system 2, a second material handling system 4, a third continuous conveying system 5, and a material injection auxiliary system 3. The first continuous conveying system 1 includes a traction rope 11 and multiple carriers 13. The traction rope 11 is set on the ground of the tunnel 6, and the carriers 13 are connected to the traction rope 11. The traction rope 11 is used to drive the carriers 13 to circulate between the inside and outside of the tunnel 6, so that the first material 9 on the carriers 13 is moved from the outside of the tunnel 6 to the inside of the tunnel 6. The second continuous conveying system 2 includes a belt 21, which is set in the tunnel. On the side wall of tunnel 6, belt 21 is used to circulate between the inside and outside of tunnel 6 so that the second material 10 in fluid form on belt 21 is moved from the inside of tunnel 6 to the material pool 8 outside tunnel 6. Second material handling system 4 is used to separate solid and liquid materials in the second material 10. Third continuous conveying system 5 is used to continuously or uninterruptedly convey the second material 10 in the material pool 8 to the outside or to the second material handling system 4. Injection auxiliary system 3 is used to inject a third material 101 in fluid form into the inner wall of tunnel 6 and inject a fourth material 102 in fluid form into the third material 101 according to the proportion.

[0085] Understandably, the traction rope 11 drives the carrier 13 to circulate between the inside and outside of tunnel 6 to continuously transport the first material 9 from the outside to the inside of tunnel 6. The belt 21 circulates between the inside and outside of tunnel 6 to continuously transport the second material 10 from the inside to the material pool 8 outside tunnel 6. The third continuous conveying system 5 continuously transports the second material 10 from the material pool 8 to the outside or uninterruptedly to the second material processing system 4 to continuously transport or process the second material 10. The injection auxiliary system 3 injects a mixture of third material 101 and fourth material 102 into the surrounding rock and segment gaps of tunnel 6 to accelerate the solidification of the third material 101 within the surrounding rock and segment gaps of tunnel 6. This effectively shortens the transport time of the first material 9 and the second material 10, the processing time of the second material 10, and the solidification time of the third material 101, thereby significantly shortening the construction period of the shield tunneling within tunnel 6, improving the efficiency of the shield tunneling within tunnel 6, and reducing the cost of the shield tunneling within tunnel 6.

[0086] It should be noted that Tunnel 6 is a passage excavated using shield tunneling equipment 7. Tunnel 6 includes an inner diameter surface and an outer diameter surface of the tunnel segments. The inner diameter surface is used for vehicles and personnel to pass through, while the outer diameter surface bears the external pressure of the surrounding rock on the tunnel segments. Because the diameter of the shield cutterhead is larger than the outer diameter of the tunnel segments, the diameter of the surrounding rock in Tunnel 6 is also larger than the outer diameter of the tunnel segments. Therefore, there is a certain volumetric gap between the surrounding rock and the tunnel segments in Tunnel 6, which requires the injection of mortar to form a new, stable structure of tunnel segments, mortar, and surrounding rock. During the shield tunneling process, as the shield tunneling equipment 7 advances, the first material 9 needs to be continuously moved from the outside of Tunnel 6 to the inside of Tunnel 6, while the second material 10 needs to be continuously moved from the inside of Tunnel 6 to the outside of Tunnel 6 to complete the construction of Tunnel 6.

[0087] The specific types of the first material 9, the second material 10, the third material 101, and the fourth material 102 can be set according to actual needs and are not limited thereto. For example, the first material 9 can be precast segments, grease cylinders, foam, walkway slabs, etc.; the second material 10 can be shield tunneling slag, mud, other waste, etc.; the third material 101 can be mortar, which is injected into the gap between the surrounding rock and the segments of tunnel 6 to form a concrete layer, so as to facilitate the fitting and installation of the segments on the inner wall of tunnel 6; correspondingly, the fourth material 102 can be an auxiliary liquid for mortar. After the auxiliary liquid is mixed with mortar in a set ratio, it reduces the cost of subsequent segment repair, secondary grouting, and leak sealing caused by the excessively long setting time of the original mortar, thereby reducing the time of synchronous grouting of the shield, improving the forming quality of the shield segments, and improving the construction efficiency of tunnel 6.

[0088] Therefore, in the shield tunneling system of this embodiment, the first materials 9, such as prefabricated segments, grease cylinders, foam, and walkway slabs required for shield tunneling, can be quickly transported from outside the tunnel 6 to inside the tunnel 6. The second materials 10, such as shield excavation soil, slurry, and other waste, can be quickly transported from inside the tunnel 6 to the material pool 8 outside the tunnel 6. At the same time, the second materials 10, such as shield excavation soil, slurry, and other waste, in the material pool 8 can be quickly processed or transported out, and the material pool 8 can be quickly emptied, so that the shield tunneling project will not have the problem of shield tunneling stopping due to the material pool 8 being full. Moreover, the fourth material 102, such as auxiliary liquid, can be mixed into the third material 101, such as mortar, thereby reducing the cost of subsequent segment repair, secondary grouting, and leak sealing caused by the excessive solidification time of the third material 101. This reduces the time of shield synchronous grouting and improves the forming quality of shield segments. Therefore, the shield tunneling system of this embodiment can significantly shorten the construction period of shield tunneling in tunnel 6, improve the efficiency of shield tunneling in tunnel 6, and reduce the cost of shield tunneling in tunnel 6.

[0089] The specific type of shield tunneling equipment 7 can be set according to actual needs and there are no restrictions on it. For example, shield tunneling equipment 7 can be a shield machine, TBM (Tunnel-Boring-Machine), etc. A temporary storage area is set at the tail of shield tunneling equipment 7 for temporary storage of materials.

[0090] The traction rope 11 is used to drive the vehicle 13 to move. The specific type of traction rope 11 can be set according to actual needs and is not limited thereto. For example, the traction rope 11 can be a rope with tensile strength such as a steel wire rope, or a chain 5304 with tensile strength, etc.

[0091] The vehicle 13 is a transport vehicle used to load the first material 9. The specific type of the vehicle 13 can be set according to actual needs and there are no restrictions on it.

[0092] The first material 9 on the carrier 13 can be loaded and unloaded by the lifting device on the shield equipment 7 or by an external lifting device, without any restriction.

[0093] The overall continuous conveying structure, which combines the traction rope 11 with the carrier 13, can also improve the overall adaptability to the turns in the tunnel 6, making the overall system have a wider range of applications.

[0094] The belt 21 is used to transport the second material 10. The specific type of belt 21 can be set according to actual needs and there are no restrictions on it.

[0095] like Figure 1As shown, in some embodiments, the traction rope 11 includes a first feeding section 1101 and a first return section 1102, which are slidably disposed on the ground of the tunnel 6. The carrier 13 is movably disposed on the ground of the tunnel 6 and is fixedly connected to the first feeding section 1101 or the first return section 1102. The first continuous conveying system 1 also includes a first driving device 12, which is disposed on the shield tunneling equipment 7 inside the tunnel 6. The first driving device 12 is connected to the traction rope 11 for transmission. The first driving device 12 is used to drive the first feeding section 1101 to move along the direction from the outside of the tunnel 6 to the inside of the tunnel 6 and to drive the first return section 1102 to move along the direction from the inside of the tunnel 6 to the outside of the tunnel 6.

[0096] Understandably, the first driving device 12 drives the traction rope 11 to move, causing the first feeding section 1101 of the traction rope 11 to move from the outside of the tunnel 6 to the inside of the tunnel 6, and causing the first return section 1102 of the traction rope 11 to move from the inside of the tunnel 6 to the outside of the tunnel 6. This enables the traction rope 11 to rotate cyclically between the inside and outside of the tunnel 6. Since the carrier 13 is fixedly connected to the first feeding section 1101 or the first return section 1102, the carrier 13 can rotate cyclically between the inside and outside of the tunnel 6 as the traction rope 11 rotates cyclically. This enables the carrier 13 to continuously transport the first material 9, thereby effectively shortening the transport time of the first material 9, improving the transport efficiency of the first material 9, and thus improving the efficiency of shield tunneling in the tunnel 6 and reducing the cost of shield tunneling in the tunnel 6.

[0097] Since the first feeding section 1101 and the first return section 1102 are slidably set on the ground of the tunnel 6, the weight of the traction rope 11 can be distributed on the ground of the tunnel 6, thereby improving the conveying stability of the carrier 13 to the first material 9 and avoiding safety problems caused by the suspension of the traction rope 11.

[0098] Meanwhile, since the first drive device 12 is installed on the shield machine 7 inside the tunnel 6, the first drive device 12 can directly drag the first feeding section 1101 of the traction rope 11, and indirectly drag the first return section 1102 of the traction rope 11. This makes the first feeding section 1101 taut and the first return section 1102 relatively slack. Therefore, compared with the method of the first drive device 12 indirectly dragging the first feeding section 1101 through the first return section 1102, the method of the first drive device 12 directly dragging the first feeding section 1101 can reduce the drag force of the first drive device 12 on the traction rope 11. This not only reduces the output power of the first drive device 12 and reduces the overall cost, but also reduces the stress on the traction rope 11, thereby reducing the usage specifications of the traction rope 11, reducing the wear of the traction rope 11, and thus extending the service life of the traction rope 11.

[0099] Moreover, since the carrier 13 is fixedly connected to the first feeding section 1101 or the first return section 1102, the carrier 13 and the traction rope 11 can move synchronously, thereby avoiding the loss of control problems such as the carrier 13 moving back and forth due to inertia during the whole process of climbing or descending the slope. This not only effectively improves the overall stability of the conveying of the first material 9, but also improves the overall safety.

[0100] It should be noted that the first feeding section 1101 and the second return section 2102 of the traction rope 11 are dynamic. That is, during the cyclic rotation of the traction rope 11, the portion of the traction rope 11 that moves from the outside of the tunnel 6 to the inside of the tunnel 6 is called the first feeding section 1101, and the portion of the traction rope 11 that moves from the inside of the tunnel 6 to the outside of the tunnel 6 is called the second return section 2102. The relative positions of the first feeding section 1101 and the second return section 2102 within the tunnel 6 can be set according to actual needs and are not limited thereto. For example, the first feeding section 1101 can be located at the center of the tunnel 6 surface, and the second return section 2102 can be located on one side of the tunnel 6 surface.

[0101] The first drive device 12 is used to drive the traction rope 11 to move in a circular motion. The specific type of the first drive device 12 can be set according to actual needs and is not limited thereto. For example, such as Figure 7As shown, the first driving device 12 includes a first driving frame 1201, at least one first driving wheel 1202, and at least one first driving member 1203. The first driving frame 1201 is disposed at the tail of the tunnel boring machine 7. The first driving wheel 1202 is rotatably mounted on the first driving frame 1201. The traction rope 11 is wound around the first driving wheel 1202 at least once. The first driving member 1203 is disposed on the first driving frame 1201 and is pulsatorically connected to the first driving wheel 1202. It can be understood that the first driving member 1203 drives the first driving wheel 1202 to rotate. The first driving wheel 1202 drives the traction rope 11 to move through the friction between itself and the traction rope 11, thereby realizing the cyclical movement of the traction rope 11. At the same time, by winding the traction rope 11 around the first driving wheel 1202 at least once, a high frictional force is ensured between the first driving wheel 1202 and the traction rope 11, thereby ensuring the stable driving of the traction rope 11 by the first driving wheel 1202.

[0102] Furthermore, by setting the first drive frame 1201 on the tunnel boring machine 7, the first drive device 12 can move forward synchronously with the tunnel boring machine 7, thereby enabling the entire system to use the tunnel boring machine 7 to overcome the tension at the storage location of the traction rope 11 to adjust the length of the traction rope 11, thus making the entire system more convenient to use.

[0103] The number of times the traction rope 11 wraps around the first drive wheel 1202 can be set according to actual needs and is not limited. For example, the number of times the traction rope 11 wraps around the first drive wheel 1202 can be one, two, three, etc.

[0104] The first drive wheel 1202 corresponds one-to-one with the first drive component 1203. The number of the first drive wheel 1202 and the first drive component 1203 can be set according to actual needs and there is no limitation. For example, the first drive wheel 1202 and the first drive component 1203 can be one, two, three, etc.

[0105] The first driving component 1203 is used to drive the first driving wheel 1202 to rotate. The specific type of the first driving component 1203 can be set according to actual needs and is not limited thereto. For example, the first driving component 1203 may include a first driving motor and a first reducer. The first driving motor and the first reducer are both mounted on the first driving frame 1201. The first driving motor is connected to the first reducer in a transmission manner, and the first reducer is connected to the first driving wheel 1202 in a transmission manner, thereby enabling the first driving motor to drive the first reducer to rotate, and the first reducer to drive the first driving wheel 1202 to rotate.

[0106] like Figure 2 and Figure 3As shown, in some embodiments, the first continuous conveying system 1 further includes a first guide rail 14, a plurality of first guide rollers 15, a second guide rail 16, and a plurality of second guide rollers 17. The first guide rail 14 is disposed on the ground of the tunnel 6, the first guide rollers 15 are rotatably disposed on the first guide rail 14, the first feeding section 1101 is disposed on the plurality of first guide rollers 15, and the first feeding section 1101 is rotatably connected to the first guide rollers 15. The second guide rail 16 is disposed on the ground of the tunnel 6, the second guide rollers 17 are rotatably disposed on the second guide rail 16, and the first return section 1102 is disposed on the plurality of second guide rollers 17, and the first return section 1102 is rotatably connected to the second guide rollers 17.

[0107] Understandably, since the first feeding section 1101 is mounted on multiple first guide rollers 15 and is tactilely connected to the first guide rollers 15, the first feeding section 1101 can be slidably mounted on the ground of the tunnel 6. At the same time, the tactile connection between the first feeding section 1101 and the multiple first guide rollers 15 reduces the frictional wear of the first feeding section 1101, thereby extending the service life of the traction rope 11. Moreover, the first guide rail 14 ensures the stable bearing of the first feeding section 1101 by the multiple first guide rollers 15, so that the vehicle 13 can travel along the set route under the stable movement of the first feeding section 1101, avoiding problems such as overturning of the vehicle 13 due to deviation of the movement trajectory.

[0108] Since the first return section 1102 is mounted on multiple second guide rollers 17 and is tactilely connected to the second guide rollers 17, the first return section 1102 can be slidably mounted on the ground of the tunnel 6. At the same time, the rolling arrangement between the first return section 1102 and the multiple second guide rollers 17 reduces the frictional loss of the first return section 1102, thereby extending the service life of the traction rope 11. Moreover, the second guide rail 16 ensures the stable bearing of the multiple second guide rollers 17 on the first return section 1102, so that the vehicle 13 can travel along the set route under the stable movement of the first return section 1102, avoiding problems such as overturning of the vehicle 13 due to deviation of the movement trajectory.

[0109] The traction rope 11 is supported by the first guide rail 14, the second guide rail 16, the first guide roller 15 on the first guide rail 14, and the second guide roller 17 on the second guide rail 16. This makes the overall erection and installation more convenient. Compared with installing brackets and other supporting components in the tunnel 6, the overall structure has lower cost and shorter construction period, while also avoiding the safety hazards of high-altitude transportation.

[0110] It should be noted that the first guide rail 14 and the second guide rail 16 are used to support the first guide roller 15 and the second guide roller 17, and in turn support the traction rope 11. The specific types of the first guide rail 14 and the second guide rail 16 can be set according to actual needs and there is no limitation thereto. For example, the first guide rail 14 and the second guide rail 16 can both be I-beams. The first guide rail 14 and the second guide rail 16 are set on the ground of the tunnel 6 along the depth direction of the tunnel 6. The depth direction of the tunnel 6 includes the direction from the inside of the tunnel 6 to the outside of the tunnel 6 and the direction from the outside of the tunnel 6 to the inside of the tunnel 6.

[0111] The mounting method of the first guide roller 15 on the first guide rail 14 and the mounting method of the second guide roller 17 on the second guide rail 16 can be set according to actual needs, and there are no restrictions on this. For example, Figure 2 As shown, multiple first supports 1401 are arranged on the first guide rail 14 along its length. The two ends of the first guide roller 15 are connected to the first supports 1401 via bearings, thereby enabling the first guide roller 15 to rotate on the first guide rail 14. Figure 3 As shown, multiple second brackets 1601 are provided on the second guide rail 16 along the length direction of the second guide rail 16. The two ends of the second guide roller 17 are connected to the second brackets 1601 through bearings, thereby realizing the rotational setting of the second guide roller 17 on the second guide rail 16.

[0112] The number of first guide rollers 15 and second guide rollers 17, as well as the spacing between adjacent first guide rollers 15 and adjacent second guide rollers 17, can be set according to actual needs and are not limited thereto.

[0113] like Figure 4 As shown, in some embodiments, the first continuous conveying system 1 further includes a plurality of third guide rollers 18 and a plurality of fourth guide rollers 19. The third guide rollers 18 are rotatably mounted on the first guide rail 14. The first feeding section 1101 is mounted on the plurality of third guide rollers 18 and is tactilely connected to the third guide rollers 18. The fourth guide rollers 19 are rotatably mounted on the second guide rail 16. The first return section 1102 is mounted on the plurality of fourth guide rollers 19 and is tactilely connected to the fourth guide rollers 19. The central axis of the first guide roller 15 and the central axis of the second guide roller 17 are arranged in the horizontal direction, and the central axis of the third guide roller 18 and the central axis of the fourth guide roller 19 are arranged in the vertical direction.

[0114] It is understandable that the first feeding section 1101 of the traction rope 11 is simultaneously mounted on the first guide roller 15 and the third guide roller 18, so that both the first guide roller 15 and the third guide roller 18 can provide load-bearing and guiding functions for the first feeding section 1101. Since the central axis of the first guide roller 15 is set in the horizontal direction and the central axis of the third guide roller 18 is set in the vertical direction, the first guide roller 15 can bear the force of the first feeding section 1101 in the vertical direction, and the third guide roller 18 can bear the force of the first feeding section 1101 in the horizontal direction. Thus, the first feeding section 1101 can make stable linear movement using the first guide roller 15 and can make stable directional movement using the third guide roller 18.

[0115] The first return segment 1102 of the traction rope 11 is simultaneously mounted on the second guide roller 17 and the fourth guide roller 19, so that both the second guide roller 17 and the fourth guide roller 19 can bear and guide the first return segment 1102. Since the central axis of the second guide roller 17 is set in the horizontal direction and the central axis of the fourth guide roller 19 is set in the vertical direction, the second guide roller 17 can bear the force of the first return segment 1102 in the vertical direction, and the fourth guide roller 19 can bear the force of the first return segment 1102 in the horizontal direction. Thus, the first return segment 1102 can make stable linear movement using the second guide roller 17 and can make stable turning movement using the fourth guide roller 19.

[0116] Thus, through the cooperation of multiple first guide rollers 15, multiple second guide rollers 17, multiple third guide rollers 18 and multiple fourth guide rollers 19, the traction rope 11 can move stably in both straight and turning motions, thereby further improving the overall adaptability to tunnel 6 and enabling the overall system to have a wider range of applications.

[0117] It should be noted that the installation method of the third guide roller 18 on the first guide rail 14 and the installation method of the fourth guide roller 19 on the second guide rail 16 can be set according to actual needs, and there are no restrictions on this. For example, the installation method of the third guide roller 18 on the first guide rail 14 can be the same as the installation method of the first guide roller 15 on the first guide rail 14, and the installation method of the fourth guide roller 19 on the second guide rail 16 can be the same as the installation method of the second guide roller 17 on the second guide rail 16.

[0118] The number of the third guide roller 18 and the fourth guide roller 19 can be set according to actual needs, and there is no limit to this.

[0119] In some embodiments, a first groove is provided on the first guide roller 15 along the circumference of the first guide roller 15, a third groove is provided on the third guide roller 18 along the circumference of the third guide roller 18, a first feeding section 1101 is disposed in the first groove and the third groove, and / or a second groove is provided on the second guide roller 17 along the circumference of the second guide roller 17, a fourth groove is provided on the fourth guide roller 19 along the circumference of the fourth guide roller 19, and a first return section 1102 is disposed in the second groove and the fourth groove.

[0120] It is understandable that by setting the first groove and the third groove, the first feeding section 1101 can be limited on the first guide roller 15 and the third guide roller 18, thereby preventing the first feeding section 1101 from coming off the first guide roller 15 and the third guide roller 18. This ensures the stable bearing and guidance of the first feeding section 1101 by the first guide roller 15 and the third guide roller 18, thereby improving the overall stability of the conveyed material.

[0121] By setting the second and fourth grooves, the first return section 1102 can be limited on the second guide roller 17 and the fourth guide roller 19, thereby preventing the first return section 1102 from coming off the second guide roller 17 and the fourth guide roller 19. This ensures that the second guide roller 17 and the fourth guide roller 19 stably support and guide the first return section 1102, thereby improving the overall stability of the conveyed material.

[0122] The arrangement of the first, second, third, and fourth grooves enables the traction rope 11 to move stably during both straight-line and turning movements, thereby further improving the overall adaptability to the tunnel 6 and giving the whole system a wider range of applications.

[0123] It should be noted that the first guide roller 15 may have a first groove and the third guide roller 18 may have a third groove, while the second guide roller 17 and the fourth guide roller 19 may not have a second groove. Alternatively, the first guide roller 15 may not have a first groove and the third guide roller 18 may not have a third groove, while the second guide roller 17 and the fourth guide roller 19 may have a second groove. Furthermore, the first guide roller 15 may have a first groove, the third guide roller 18 may have a third groove, the second guide roller 17 may have a second groove, and the fourth guide roller 19 may have a fourth groove. There are no restrictions on this.

[0124] The first, second, third, and fourth grooves are used to limit the traction rope 11. The specific types of the first, second, third, and fourth grooves can be set according to actual needs and are not limited thereto. For example, the first, second, third, and fourth grooves can be annular grooves respectively opened on the first guide roller 15, second guide roller 17, third guide roller 18, and fourth guide roller 19. Alternatively, the first guide roller 15, second guide roller 17, third guide roller 18, and fourth guide roller 19 can be set with a structure where the diameter in the middle is small and the diameter at both ends is large, so that the first, second, third, and fourth grooves are respectively formed on the first guide roller 15, second guide roller 17, third guide roller 18, and fourth guide roller 19.

[0125] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the carrier 13 includes a disc 1301 and a plurality of rollers 1302. The rollers 1302 are rotatably mounted on the disc 1301 and roll on the ground of the tunnel 6. The disc 1301 is located above the first guide rail 14 and is fixedly connected to the first feeding section 1101. The plurality of rollers 1302 are located on both sides of the first guide rail 14. Alternatively, the disc 1301 is located above the second guide rail 16 and is fixedly connected to the first return section 1102. The plurality of rollers 1302 are located on both sides of the second guide rail 16.

[0126] Understandably, since the rollers 1302 are rotatably mounted on the disc 1301 and roll on the ground of the tunnel 6, the disc 1301 can move on the ground of the tunnel 6. Since the disc 1301 is fixedly connected to the first feeding section 1101 or the first return section 1102, the traction rope 11 can drive the disc 1301 to move on the ground of the tunnel 6, thereby realizing the continuous conveying of the first material 9. At the same time, since multiple rollers 1302 are located on both sides of the first guide rail 14 or the second guide rail 16, the disc 1301 can be evenly stressed when driven by the first feeding section 1101 or the first return section 1102, thereby ensuring the stable conveying of the first material 9 by the disc 1301.

[0127] It should be noted that when the carrier 13 is located in the first feeding section 1101, the disc 1301 is located above the first guide rail 14, the disc 1301 is fixedly connected to the first feeding section 1101, and multiple rollers 1302 are located on both sides of the first guide rail 14. When the carrier 13 is located in the first return section 1102, the disc 1301 is located above the second guide rail 16, the disc 1301 is fixedly connected to the first return section 1102, and multiple rollers 1302 are located on both sides of the second guide rail 16.

[0128] The tray 1301 is used to load the first material 9. The specific type of the tray 1301 can be set according to actual needs and there are no restrictions on it.

[0129] The roller 1302 is used to support the disc 1301 and enable the disc 1301 to move. The specific type of roller 1302 can be set according to actual needs and there is no restriction on it.

[0130] The number of rollers 1302 can be set according to actual needs and there is no limit to it. For example, there can be four rollers 1302, which are located on both sides of the first guide rail 14 or the second guide rail 16 respectively.

[0131] like Figure 2 and Figure 3 As shown, in some embodiments, the carrier 13 further includes a first clamping roller 1303 and a second clamping roller 1304. The first clamping roller 1303 is rotatably mounted on the disc body 1301, and the second clamping roller 1304 is rotatably mounted on the disc body 1301. The first clamping roller 1303 and the second clamping roller 1304 are respectively rotatably connected to both sides of the first guide rail 14, or the first clamping roller 1303 and the second clamping roller 1304 are respectively rotatably connected to both sides of the second guide rail 16.

[0132] It is understandable that, since the first clamping roller 1303 and the second clamping roller 1304 are respectively rolledly connected to both sides of the first guide rail 14, or the first clamping roller 1303 and the second clamping roller 1304 are respectively rolledly connected to both sides of the second guide rail 16, the first clamping roller 1303 and the second clamping roller 1304 can limit the carrier 13 to the first guide rail 14 or the second guide rail 16, thereby avoiding problems such as tilting, shaking or detachment of the carrier 13 when the traction rope 11 drives the carrier 13 to move, thus ensuring that the carrier 13 can travel along the set route and achieve stable conveying of the first material 9.

[0133] It should be noted that when the carrier 13 is located in the first feeding section 1101, the first clamping roller 1303 and the second clamping roller 1304 are respectively tumblingly connected to both sides of the first guide rail 14. When the carrier 13 is located in the first return section 1102, the first clamping roller 1303 and the second clamping roller 1304 are respectively tumblingly connected to both sides of the second guide rail 16.

[0134] The arrangement of the first clamping roller 1303 and the second clamping roller 1304 on the disk body 1301 can be set according to actual needs, and there are no restrictions on this. For example, Figure 2 and Figure 3As shown, a third bracket 1309 and a fourth bracket 1311 are provided on both sides of the first guide rail 14 or the second guide rail 16 on the disc body 1301. The two ends of the first clamping roller 1303 are connected to the third bracket 1309 through bearings, and the two ends of the second clamping roller 1304 are connected to the fourth bracket 1311 through bearings.

[0135] Among them, such as Figure 2 and Figure 3 As shown, taking the first guide rail 14 as an example, a fifth guide roller 1310 can be set on the side of the third bracket 1309 near the first guide roller 15. The rotation center axis of the fifth guide roller 1310 is perpendicular to the rotation center axis of the first clamping roller 1303. A sixth guide roller 1312 can be set on the side of the fourth bracket 1311 near the first guide roller 15. The rotation center axis of the sixth guide roller 1312 is perpendicular to the rotation center axis of the second clamping roller 1304. Thus, when the carrier 13 tilts and the third bracket 1309 and the fourth bracket 1311 shift in the direction close to the first guide roller 15, direct contact between the third bracket 1309 and the fourth bracket 1311 and the first guide rail 14 can be avoided, thereby avoiding wear between the third bracket 1309 and the fourth bracket 1311 and the first guide rail 14, and making the movement of the carrier 13 smoother.

[0136] The first clamping roller 1303 and the second clamping roller 1304 are used to roll in connection with the side of the first guide rail 14 or the second guide rail 16 to clamp the first guide rail 14 or the second guide rail 16. The specific types of the first clamping roller 1303 and the second clamping roller 1304 can be set according to actual needs and there is no limitation thereto.

[0137] like Figure 5 As shown, in some embodiments, the carrier 13 further includes a first fixing rope 1305, a first gripper 1306, a second fixing rope 1307, and a second gripper 1308. The first fixing rope 1305 is disposed at one end of the disc body 1301, the first gripper 1306 is disposed at the end of the first fixing rope 1305 away from the disc body 1301, the second fixing rope 1307 is disposed at the end of the disc body 1301 away from the first fixing rope 1305, and the second gripper 1308 is disposed at the end of the second fixing rope 1307 away from the disc body 1301. The first gripper 1306 and the second gripper 1308 are detachably connected to the first feeding section 1101, or the first gripper 1306 and the second gripper 1308 are detachably connected to the first return section 1102.

[0138] Understandably, since the first fixing rope 1305 is located at one end of the disc body 1301, and the first gripper 1306 is located at the end of the first fixing rope 1305 away from the disc body 1301, and the first gripper 1306 is detachably connected to the first feeding section 1101 or the first return section 1102, one end of the disc body 1301 can be fixedly connected to the first feeding section 1101 or the first return section 1102. Simultaneously, since the second fixing rope 1307 is located at one end of the disc body 1301, and the second gripper 1308 is located at the end of the second fixing rope 1307 away from the disc body 1301, and the second gripper 1308 is detachably connected to the first feeding section 1101 or the first return section 1102... The connection between the unloading and the first feeding section 1101 or the first return section 1102 allows the other end of the disc 1301 to be fixedly connected. Thus, through the setting of the first gripper 1306 and the second gripper 1308, the carrier 13 is fixedly connected to the traction rope 11, ensuring the continuous conveying of the first material 9 by the carrier 13. Furthermore, through the setting of the first fixed rope 1305 and the second fixed rope 1307, the carrier 13 and the traction rope 11 can move synchronously, thereby avoiding the loss of control problems such as the carrier 13 moving back and forth due to inertia during the process of climbing or descending slopes. This not only effectively improves the overall conveying stability of the first material 9, but also improves the overall safety.

[0139] Moreover, since the first gripper 1306 and the second gripper 1308 are detachably connected to the first feeding section 1101 or the first return section 1102 respectively, the carrier 13 is stably connected to the traction rope 11 while facilitating the separation of the carrier 13 from the traction rope 11, thereby making the conveying of the first material 9 by the carrier 13 more flexible and convenient.

[0140] It should be noted that when the carrier 13 is located in the first feeding section 1101, the first gripper 1306 and the second gripper 1308 are connected to the first feeding section 1101. When the carrier 13 is located in the first return section 1102, the first gripper 1306 and the second gripper 1308 are connected to the first return section 1102.

[0141] The first fixing rope 1305 and the second fixing rope 1307 are used to fix the vehicle 13 and the traction rope 11. The specific types of the first fixing rope 1305 and the second fixing rope 1307 can be set according to actual needs and there is no limitation. For example, the first fixing rope 1305 and the second fixing rope 1307 can be ropes with tensile strength such as steel wire ropes, or chains with tensile strength such as chain 5304.

[0142] The first cable gripper 1306 and the second cable gripper 1308 are used to connect to the traction rope 11. Both the first cable gripper 1306 and the second cable gripper 1308 are cable grippers. The specific types of the first cable gripper 1306 and the second cable gripper 1308 can be set according to actual needs and are not limited thereto. For example, both the first cable gripper 1306 and the second cable gripper 1308 include a first clamping rod and a second clamping rod. The middle part of the first clamping rod is hinged to the middle part of the second clamping rod. A spring is provided between one end of the first clamping rod and one end of the second clamping rod. A clamping opening is formed between the other end of the first clamping rod and the other end of the second clamping rod. The clamping opening is stably clamped on the traction rope 11 under the action of the spring.

[0143] The method of attaching and detaching the first rope gripper 1306 and the second rope gripper 1308 on the traction rope 11 can be set according to actual needs and is not limited. For example, the attachment and detachment of the first rope gripper 1306 and the second rope gripper 1308 can be done manually or automatically by using mechanical equipment.

[0144] like Figure 1 As shown, in some embodiments, the first continuous conveying system 1 further includes a first uncoupling device 112 and / or a second uncoupling device 113. The first uncoupling device 112 is located on the ground of the tunnel 6 near the tail of the shield machine 7. The end of the first feeding section 1101 near the shield machine 7 passes through the first uncoupling device 112. The second uncoupling device 113 is located on the ground of the tunnel 6 away from the shield machine 7. The end of the first return section 1102 away from the shield machine 7 passes through the second uncoupling device 113.

[0145] It is understandable that by setting the first uncoupling device 112, the first cable gripper 1306 and the second cable gripper 1308 can be automatically separated from the first feeding section 1101 using the first uncoupling device 112, thereby simplifying the separation operation between the carrier 13 and the traction rope 11 and making the overall use more convenient.

[0146] By setting the second release device 113, the first cable gripper 1306 and the second cable gripper 1308 can be automatically separated from the first return section 1102 using the second release device 113, thereby simplifying the separation operation between the vehicle 13 and the towing rope 11 and making the overall use more convenient.

[0147] It should be noted that the first continuous conveying system 1 may include only the first uncoupling device 112, or only the second uncoupling device 113, or both the first uncoupling device 112 and the second uncoupling device 113, without any limitation.

[0148] The installation method of the first unattachment device 112 and the second unattachment device 113 on the ground of tunnel 6 can be set according to actual needs, and there is no restriction on it. For example, the first unattachment device 112 can be installed on the shield equipment 7, and the second unattachment device 113 can be installed directly on the ground of tunnel 6.

[0149] The first disengagement device 112 and the second disengagement device 113 are used for the automatic separation of the first cable gripper 1306 and the second cable gripper 1308 from the traction rope 11. The specific types of the first disengagement device 112 and the second disengagement device 113 can be set according to actual needs and are not limited thereto. For example, both the first disengagement device 112 and the second disengagement device 113 include a first limiting plate, a second limiting plate, a third limiting plate, and a fourth limiting plate. The first limiting plate and the second limiting plate are located on one side of the traction rope 11, and the third limiting plate and the fourth limiting plate are located on the other side of the traction rope 11. The distance between the first limiting plate and the second limiting plate decreases linearly along the forward direction of the traction rope 11, and the distance between the third limiting plate and the fourth limiting plate decreases linearly along the forward direction of the traction rope 11. Thus, in the first... When the first and second clamping rods of the first gripper 1306 pass between the first and second limiting plates, the ends of the first and second clamping rods away from the clamping opening of the first gripper 1306 move closer together, thereby gradually enlarging the clamping opening of the first gripper 1306 and eventually disengaging from the traction rope 11, thus separating the first gripper 1306 from the traction rope 11. When the first and second clamping rods of the second gripper 1308 pass between the third and fourth limiting plates, the ends of the first and second clamping rods away from the clamping opening of the second gripper 1308 move closer together, thereby gradually enlarging the clamping opening of the second gripper 1308 and eventually disengaging from the traction rope 11, thus separating the second gripper 1308 from the traction rope 11.

[0150] Guide wheels can be provided at the ends of the first clamping rod and the second clamping rod that are away from the clamping opening to reduce wear on the first clamping rod and the second clamping rod.

[0151] like Figure 1 and Figure 6As shown, in some embodiments, the first continuous conveying system 1 further includes a rope storage device 110. The rope storage device 110 includes a first tensioning fixing frame 11001, a first tensioning sliding frame 11002, and a plurality of rope storage wheels 11003. The first tensioning fixing frame 11001 is disposed on the ground of the tunnel 6. The first tensioning sliding frame 11002 is slidably disposed relative to the first tensioning fixing frame 11001. The plurality of rope storage wheels 11003 are respectively rotatably disposed on the first tensioning fixing frame 11001 and the first tensioning sliding frame 11002, and the plurality of rope storage wheels 11003 are staggered. The end of the first feeding section 1101 away from the shield equipment 7 and the end of the first return section 1102 away from the shield equipment 7 are respectively connected after passing around the plurality of rope storage wheels 11003.

[0152] Understandably, since the end of the first feeding section 1101 away from the shield equipment 7 and the end of the first return section 1102 away from the shield equipment 7 are connected after passing through multiple rope storage wheels 11003 respectively, a portion of the traction rope 11 can be stored between the first tensioning fixed frame 11001 and the first tensioning sliding frame 11002. Furthermore, since the first tensioning sliding frame 11002 is slidably set relative to the first tensioning fixed frame 11001, the relative position of the first tensioning sliding frame 11002 and the first tensioning fixed frame 11001 can be adjusted. Thus, the release and storage of the traction rope 11 can be achieved by moving the first tensioning sliding frame 11002, thereby enabling the length of the traction rope 11 to adapt to the continuous advancement of the shield equipment 7 and ensuring the stable transportation of the first material 9 in the tunnel 6.

[0153] It should be noted that the sliding method of the first tensioning sliding frame 11002 relative to the first tensioning fixed frame 11001 can be set according to actual needs and is not limited thereto. For example, the bottom of the first tensioning sliding frame 11002 is provided with a traveling wheel, and a wheel track is provided on the ground near the first tensioning fixed frame 11001. The traveling wheel rolls within the wheel track, thereby realizing the sliding setting of the first tensioning sliding frame 11002 relative to the first tensioning fixed frame 11001.

[0154] The first tensioning sliding frame 11002 and the first tensioning fixing frame 11001 are used to adjust the length of the traction rope 11. The specific types of the first tensioning sliding frame 11002 and the first tensioning fixing frame 11001 can be set according to actual needs and there are no restrictions on them.

[0155] The arrangement of the rope storage pulley 11003 on the first tensioning fixing frame 11001 and the first tensioning sliding frame 11002 can be configured according to actual needs and is not limited thereto. For example, the rope storage pulley 11003 includes a pulley frame, a pulley axle, and a pulley body. The pulley frame is fixedly mounted on the first tensioning fixing frame 11001, the pulley axle is fixedly mounted on the pulley frame, and the pulley body is rotatably mounted on the pulley axle via bearings. An annular groove can be provided on the outer circumferential surface of the pulley body to facilitate the winding of the traction rope 11 and ensure the stable mounting of the traction rope 11 on the rope storage pulley 11003.

[0156] The more rope storage wheels 11003 there are, the greater the storage capacity of the traction rope 11 and the longer the adjustable length of the traction rope 11. The number of rope storage wheels 11003 can be set according to actual needs and there is no limit to it.

[0157] Multiple guide wheels can also be installed between the various devices to facilitate the turning of the traction rope 11 during its cyclical movement.

[0158] like Figure 1 and Figure 6 As shown, in some embodiments, the first continuous conveying system 1 further includes a first tensioning device 111. The first tensioning device 111 includes a first tensioning frame 11101, a plurality of first tensioning rollers 11102, a plurality of second tensioning rollers 11103, a first tensioning rope 11104, and a first winch 11105. The first tensioning frame 11101 is disposed on the ground of the tunnel 6. The first tensioning rollers 11102 are rotatably disposed on the first tensioning sliding frame 11002. The second tensioning rollers 11103 are rotatably disposed on the first tensioning frame 11101. The first winch 11105 is disposed on the ground of the tunnel 6. One end of the first tensioning rope 11104 is connected to the reel of the first winch 11105. The other end of the first tensioning rope 11104 passes around the plurality of first tensioning rollers 11102 and the plurality of second tensioning rollers 11103 and is connected to the first tensioning frame 11101.

[0159] Understandably, the first winch 11105 drives the reel thereon to wind the first tensioning rope 11104, so that the first tensioning rope 11104 applies a constant force on the first tensioning sliding frame 11002 in a direction away from the first tensioning fixed frame 11001, thereby ensuring the tension of the traction rope 11. When the tension of the shield equipment 7 on the traction rope 11 is greater than the constant force output by the first winch 11105, it can overcome the driving force of the first winch 11105 and make the first tensioning sliding frame 11002 move in a direction closer to the first tensioning fixed frame 11001, thereby extending the length of the traction rope 11. Thus, by setting the first tensioning device 111, not only can the stable adjustment of the length of the traction rope 11 be ensured, but also the stable driving of the traction rope 11 on the carrier 13 can be ensured.

[0160] It should be noted that the first winch 11105 is used to apply tension to the first tensioning sliding frame 11002. The specific type of the first winch 11105 can be set according to actual needs and is not limited thereto. For example, the first winch 11105 may include a first winding frame, a first reel, a first variable frequency motor and a second reducer. The first winding frame is fixedly set on the ground of the tunnel 6, the first reel is rotatably set on the first winding frame, the first variable frequency motor and the second reducer are fixedly set on the first winding frame, the first variable frequency motor is driven by the second reducer, the second reducer is driven by the first reel, the first variable frequency motor is driven by the first frequency converter, and the first frequency converter enables the first variable frequency motor to output constant torque, thereby ensuring that the force applied by the first tensioning rope 11104 on the first tensioning sliding frame 11002 is a constant force.

[0161] The first winch 11105 may also include a first brake. The brake of the first brake is connected to the output shaft of the second reducer. In an emergency or when the machine stops, the brake of the first brake engages to lock the second reducer, thereby preventing the first tension rope 11104 from rotating in the opposite direction and enabling the first tensioning device 111 to maintain tension.

[0162] The specific type of the first tension rope 11104 can be set according to actual needs and there are no restrictions on it. The first tension rope 11104 can be a rope with tensile strength such as a steel wire rope, or a chain 5304 with tensile strength, etc.

[0163] The first tensioning pulley 11102 and the second tensioning pulley 11103 are used to steer the first tensioning rope 11104. The specific types of the first tensioning pulley 11102 and the second tensioning pulley 11103 can be set according to actual needs and are not limited thereto. For example, taking the first tensioning pulley 11102 as an example, the first tensioning pulley 11102 includes a wheel frame, a wheel axle, and a wheel body. The wheel frame is fixedly mounted on the first tensioning sliding frame 11002, the wheel axle is fixedly mounted on the wheel frame, and the wheel body is rotatably mounted on the wheel axle through a bearing. An annular groove can be provided on the outer circumference of the wheel body to facilitate the winding of the first tensioning rope 11104 and ensure the stable mounting of the first tensioning rope 11104 on the first tensioning pulley 11102.

[0164] A guide wheel can be set between the second tensioning pulley 11103 and the first tensioning pulley 11102 as needed. The first tensioning rope 11104 passes around the guide wheel, thereby ensuring the stable setting of the first tensioning rope 11104 between the second tensioning pulley 11103 and the first tensioning pulley 11102.

[0165] The specific location of the first tensioning device 111 can be set according to actual needs and is not limited thereto. For example, the first driving device 12, the rope storage device 110 and the first tensioning device 111 are set along the direction from the inside of the tunnel 6 to the outside of the tunnel 6.

[0166] like Figure 8 As shown, in some embodiments, the belt 21 includes a second feeding section 2101 and a second return section 2102. The second feeding section 2101 and the second return section 2102 are slidably disposed on the sidewall of the tunnel 6. The second continuous conveying system 2 also includes a second driving device 22. The second driving device 22 is disposed at the end of the tunnel 6 ground away from the shield equipment 7. The second driving device 22 is connected to the belt 21 for transmission. The second driving device 22 is used to drive the second feeding section 2101 to move along the direction from the inside of the tunnel 6 to the outside of the tunnel 6 and to drive the second return section 2102 to move along the direction from the outside of the tunnel 6 to the inside of the tunnel 6.

[0167] Understandably, the second drive device 22 drives the belt 21 to move, causing the second feeding section 2101 of the belt 21 to move from the inside of the tunnel 6 to the outside of the tunnel 6, and causing the second return section 2102 of the belt 21 to move from the outside of the tunnel 6 to the inside of the tunnel 6. This enables the belt 21 to rotate cyclically between the inside and outside of the tunnel 6, thereby achieving continuous conveying of the second material 10 by the belt 21. This effectively shortens the conveying time of the second material 10, improves the conveying efficiency of the second material 10, and thus improves the efficiency of shield tunneling construction in the tunnel 6 and reduces the cost of shield tunneling construction in the tunnel 6.

[0168] Since the second feeding section 2101 and the second return section 2102 are respectively slidably installed on the side wall of the tunnel 6, the belt 21 can reduce the occupation of the ground space of the tunnel 6, avoid the congestion of the ground of the tunnel 6, thereby improving the efficiency of shield tunneling in the tunnel 6 and reducing the cost of shield tunneling in the tunnel 6.

[0169] Meanwhile, since the second drive device 22 is located at the end of the tunnel 6 away from the shield equipment 7, it can directly drag the second feeding section 2101 of the belt 21 and indirectly drag the second return section 2102 of the belt 21. This results in the second feeding section 2101 being in a taut state and the second return section 2102 being in a relatively slack state. Therefore, compared to the second drive device 22 indirectly dragging the second feeding section 2101 through the second return section 2102, the second drive device 22 directly dragging the second feeding section 2101 reduces the drag force of the second drive device 22 on the belt 21. This not only reduces the output power of the second drive device 22 and the overall cost, but also reduces the stress on the belt 21, thereby reducing the usage specifications of the belt 21, reducing the wear of the belt 21, and extending the service life of the belt 21.

[0170] It should be noted that the second feeding section 2101 and the second return section 2102 of the belt 21 are dynamic. That is, during the cyclic rotation of the belt 21, the portion of the belt 21 that moves from the outside to the inside of the tunnel 6 is called the second return section 2102, and the portion of the belt 21 that moves from the inside to the outside of the tunnel 6 is called the second feeding section 2101. The relative positions of the second feeding section 2101 and the second return section 2102 within the tunnel 6 can be set according to actual needs and are not limited. For example, the second feeding section 2101 can be located above the second return section 2102.

[0171] The second drive device 22 is used to drive the cyclic movement of the belt 21. The specific type of the second drive device 22 can be set according to actual needs and is not limited thereto. For example, Figure 8As shown, the second drive device 22 includes a second drive frame 2201, multiple second drive wheels 2202, multiple second drive components 2203, and a first steering wheel 2204. The second drive frame 2201 is located on the ground of the tunnel 6 at the end away from the shield machine 7. The second drive wheels 2202 are rotatably mounted on the second drive frame 2201. The belt 21 passes around the multiple second drive wheels 2202 in sequence. The second drive components 2203 are mounted on the second drive frame 2201 and are connected to the second drive wheels 2202 in a transmission manner. The first steering wheel 2204 is rotatably mounted on the shield machine 7. The end of the second feeding section 2101 near the shield machine 7 and the end of the second return section 2102 near the shield machine 7 are connected after passing around the first steering wheel 2204. It is understandable that the second driving component 2203 drives the second driving wheel 2202 to rotate, and the second driving wheel 2202 drives the belt 21 to move through the friction between the second driving wheel 2202 and the belt 21, thereby realizing the cyclic movement of the belt 21. At the same time, by simultaneously winding the belt 21 around multiple second driving wheels 2202, the stable drive of the belt 21 by multiple second driving wheels 2202 is ensured.

[0172] Furthermore, by setting the first steering wheel 2204 on the shield machine 7, the first steering wheel 2204 can move forward synchronously with the shield machine 7, thereby enabling the entire system to use the shield machine 7 to overcome the tension at the belt storage point to adjust the length of the belt 21, thus making the entire system more convenient to use.

[0173] The way the belt 21 is wound around the multiple second drive wheels 2202 can be set according to actual needs and is not limited. For example, the belt 21 can be wound around the multiple second drive wheels 2202 in a serpentine structure.

[0174] The second drive wheel 2202 corresponds one-to-one with the second drive component 2203. The number of the second drive wheel 2202 and the second drive component 2203 can be set according to actual needs and there is no limitation. For example, there can be two, three, four, etc.

[0175] The second driving component 2203 is used to drive the second driving wheel 2202 to rotate. The specific type of the second driving component 2203 can be set according to actual needs and is not limited thereto. For example, the second driving component 2203 may include a second driving motor and a third reducer. The second driving motor and the third reducer are both mounted on the second driving frame 2201. The second driving motor is connected to the third reducer in a transmission manner, and the third reducer is connected to the second driving wheel 2202 in a transmission manner, thereby enabling the second driving motor to drive the third reducer to rotate, and the third reducer to drive the second driving wheel 2202 to rotate.

[0176] like Figure 9As shown, in some embodiments, the second continuous conveying system 2 further includes a belt storage device 23. The belt storage device 23 includes a second tensioning fixing frame 2301, a second tensioning sliding frame 2302, and a plurality of belt storage wheels 2303. The second tensioning fixing frame 2301 is disposed on the ground of the tunnel 6. The second tensioning sliding frame 2302 is slidably disposed relative to the second tensioning fixing frame 2301. The plurality of belt storage wheels 2303 are respectively rotatably disposed on the second tensioning fixing frame 2301 and the second tensioning sliding frame 2302, and the plurality of belt storage wheels 2303 are staggered. The end of the second feeding section 2101 away from the shield equipment 7 and the end of the second return section 2102 away from the shield equipment 7 are respectively connected after passing around the plurality of belt storage wheels 2303.

[0177] It is understandable that, since the end of the second feeding section 2101 away from the shield equipment 7 and the end of the second return section 2102 away from the shield equipment 7 are connected after passing through multiple storage pulleys 2303, a portion of the belt 21 can be stored between the second tensioning fixed frame 2301 and the second tensioning sliding frame 2302. Furthermore, since the second tensioning sliding frame 2302 is slidably set relative to the second tensioning fixed frame 2301, the relative position of the second tensioning sliding frame 2302 and the second tensioning fixed frame 2301 can be adjusted. Thus, the movement of the second tensioning sliding frame 2302 can realize the release and storage of the belt 21, thereby enabling the length of the belt 21 to adapt to the continuous advancement of the shield equipment 7 and ensuring the stable transportation of the second material 10 in the tunnel 6.

[0178] It should be noted that the sliding method of the second tensioning sliding frame 2302 relative to the second tensioning fixed frame 2301 can be set according to actual needs and is not limited thereto. For example, the bottom of the second tensioning sliding frame 2302 is provided with a traveling wheel, and a wheel track is provided on the ground near the second tensioning fixed frame 2301. The traveling wheel rolls within the wheel track, thereby realizing the sliding setting of the second tensioning sliding frame 2302 relative to the second tensioning fixed frame 2301.

[0179] The second tensioning sliding bracket 2302 and the second tensioning fixing bracket 2301 are used to adjust the length of the belt 21. The specific types of the second tensioning sliding bracket 2302 and the second tensioning fixing bracket 2301 can be set according to actual needs and there are no restrictions on them.

[0180] The arrangement of the belt storage pulley 2303 on the second tension fixing frame 2301 and the second tension sliding frame 2302 can be configured according to actual needs and is not limited thereto. For example, the belt storage pulley 2303 includes a pulley frame, a pulley axle, and a pulley body. The pulley frame is fixedly mounted on the second tension fixing frame 2301, the pulley axle is fixedly mounted on the pulley frame, and the pulley body is rotatably mounted on the pulley axle via bearings. An annular groove can be provided on the outer circumferential surface of the pulley body to facilitate the winding of the belt 21 and ensure the stable mounting of the belt 21 on the belt storage pulley 2303.

[0181] The more belt storage pulleys 2303 there are, the greater the storage capacity of belt 21 and the longer the adjustable length of belt 21. The number of belt storage pulleys 2303 can be set according to actual needs and there is no limit to it.

[0182] Multiple guide wheels can also be installed between the various devices to facilitate steering during the cyclic movement of the belt 21.

[0183] like Figure 9 As shown, in some embodiments, the second continuous conveying system 2 further includes a second tensioning device 24. The second tensioning device 24 includes a second tensioning frame 2401, a plurality of third tensioning rollers 2402, a plurality of fourth tensioning rollers 2403, a second tensioning rope 2404, and a second winch 2405. The second tensioning frame 2401 is disposed on the ground of the tunnel 6. The third tensioning rollers 2402 are rotatably disposed on the second tensioning sliding frame 2302. The fourth tensioning rollers 2403 are rotatably disposed on the second tensioning frame 2401. The second winch 2405 is disposed on the ground of the tunnel 6. One end of the second tensioning rope 2404 is connected to the reel of the second winch 2405. The other end of the second tensioning rope 2404 passes over the plurality of third tensioning rollers 2402 and the plurality of fourth tensioning rollers 2403 and is then connected to the second tensioning frame 2401.

[0184] Understandably, the second winch 2405 drives the reel thereon to wind the second tensioning rope 2404, so that the second tensioning rope 2404 applies a constant force on the second tensioning sliding frame 2302 in a direction away from the second tensioning fixed frame 2301, thereby ensuring the tension of the belt 21. When the tension of the shield equipment 7 on the belt 21 is greater than the constant force output by the second winch 2405, the driving force of the second winch 2405 can be overcome, and the second tensioning sliding frame 2302 can be moved in a direction closer to the second tensioning fixed frame 2301, thereby extending the length of the belt 21. Thus, by setting the second tensioning device 24, not only can the stable adjustment of the length of the belt 21 be ensured, but also the stable driving of the belt 21 on the second material 10 can be ensured.

[0185] It should be noted that the second winch 2405 is used to apply tension to the second tensioning sliding frame 2302. The specific type of the second winch 2405 can be set according to actual needs and is not limited thereto. For example, the second winch 2405 may include a second winding frame, a second reel, a second variable frequency motor, and a fourth reducer. The second winding frame is fixedly set on the ground of tunnel 6, the second reel is rotatably set on the second winding frame, the second variable frequency motor and the fourth reducer are fixedly set on the second winding frame, the second variable frequency motor is driven by the fourth reducer, the fourth reducer is driven by the second reel, the second variable frequency motor is driven by the second frequency converter, and the second frequency converter enables the second variable frequency motor to output constant torque, thereby ensuring that the force applied by the second tensioning rope 2404 on the second tensioning sliding frame 2302 is a constant force.

[0186] The second winch 2405 may also include a second brake, the brake of which is connected to the output shaft of the fourth reducer. In an emergency or when the machine stops, the brake of the second brake engages to lock the fourth reducer, thereby preventing the second tension rope 2404 from rotating in the opposite direction and enabling the second tensioning device 24 to maintain tension.

[0187] The specific type of the second tension rope 2404 can be set according to actual needs and there are no restrictions on it. The second tension rope 2404 can be a rope with tensile strength such as a steel wire rope, or a chain 5304 with tensile strength, etc.

[0188] The third tensioning pulley 2402 and the fourth tensioning pulley 2403 are used to steer the second tensioning rope 2404. The specific types of the third tensioning pulley 2402 and the fourth tensioning pulley 2403 can be set according to actual needs and are not limited thereto. For example, taking the third tensioning pulley 2402 as an example, the third tensioning pulley 2402 includes a wheel frame, a wheel axle, and a wheel body. The wheel frame is fixedly mounted on the second tensioning sliding frame 2302, the wheel axle is fixedly mounted on the wheel frame, and the wheel body is rotatably mounted on the wheel axle through a bearing. An annular groove can be provided on the outer circumference of the wheel body to facilitate the winding of the second tensioning rope 2404 and ensure the stable mounting of the second tensioning rope 2404 on the third tensioning pulley 2402.

[0189] A guide wheel can be set between the third tensioning pulley 2402 and the fourth tensioning pulley 2403 as needed. The second tensioning rope 2404 passes around the guide wheel, thereby ensuring the stable setting of the second tensioning rope 2404 between the third tensioning pulley 2402 and the fourth tensioning pulley 2403.

[0190] The specific location of the second tensioning device 24 can be set according to actual needs and is not limited thereto. For example, the second drive device 22, the belt storage device 23 and the second tensioning device 24 are set along the direction from the inside of the tunnel 6 to the outside of the tunnel 6.

[0191] The first drive device 12 is located on the shield tunneling equipment 7, while the rope storage device 110, the first tensioning device 111, the second drive device 22, the belt storage device 23, and the second tensioning device 24 are all located outside the tunnel 6.

[0192] like Figure 8 As shown, in some embodiments, the second continuous conveying system 2 further includes a plurality of support devices 25, which are spaced apart on the inner wall of the tunnel 6 along the direction from the outside to the inside of the tunnel 6. Each support device 25 includes a fifth support 2501, a sixth support 2502, a plurality of first idlers 2503, and a plurality of second idlers 2504. The fifth support 2501 is disposed on the inner wall of the tunnel 6, the sixth support 2502 is disposed on the fifth support 2501, the plurality of first idlers 2503 are rotatably disposed on the fifth support 2501, the second return section 2102 is disposed on the plurality of first idlers 2503 and the first idlers 2503 are rotatably connected to the second return section 2102, the plurality of second idlers 2504 are rotatably disposed on the sixth support 2502, and the second feeding section 2101 is disposed on the plurality of second idlers 2504 and the second idlers 2504 are rotatably connected to the second feeding section 2101.

[0193] Understandably, since the second feeding section 2101 is mounted on multiple second idlers 2504 and the second idlers 2504 are tumblingly connected to the second feeding section 2101, the second feeding section 2101 can slide on the inner wall of the tunnel 6. At the same time, the rolling arrangement between the second feeding section 2101 and the multiple second idlers 2504 reduces the frictional loss of the second feeding section 2101, thereby extending the service life of the belt 21. Moreover, the sixth bracket 2502 ensures the stable bearing of the multiple second idlers 2504 on the second feeding section 2101, so that the second material 10 can travel along the set route under the stable movement of the second feeding section 2101, avoiding problems such as overturning.

[0194] Since the second return section 2102 is mounted on multiple first idlers 2503 and the first idlers 2503 are tumblingly connected to the second return section 2102, the second return section 2102 can be slidably mounted on the inner wall of the tunnel 6. At the same time, the rolling arrangement between the second return section 2102 and the multiple first idlers 2503 reduces the frictional loss of the second return section 2102, thereby extending the service life of the belt 21. Moreover, the fifth bracket 2501 ensures the stable bearing of the second return section 2102 by the multiple first idlers 2503, thereby ensuring the stable cyclic movement of the belt 21 and avoiding problems such as overturning.

[0195] The belt 21 is supported by the fifth support 2501 and the sixth support 2502, as well as the first idler 2503 on the fifth support 2501 and the second idler 2504 on the sixth support 2502, which makes the overall installation on the side wall of the tunnel 6 more convenient.

[0196] It should be noted that the fifth support 2501 and the sixth support 2502 are used to support the first idler 2503 and the second idler 2504, and thus support the belt 21. The specific types of the fifth support 2501 and the sixth support 2502 can be set according to actual needs and are not limited thereto. For example, the fifth support 2501 can be an arc-shaped support fixed on the tunnel 6 segment, and the sixth support 2502 can be a U-shaped support fixed on the fifth support 2501.

[0197] The mounting method of the first idler roller 2503 on the fifth support 2501 and the mounting method of the second idler roller 2504 on the sixth support 2502 can be set according to actual needs and are not limited thereto. For example, multiple first support plates are provided on the fifth support 2501 along the width direction of the tunnel 6, and the first idler roller 2503 is set between adjacent first support plates through bearings, thereby realizing the rotational setting of multiple first idler rollers 2503 on the fifth support 2501. Multiple second support plates are provided on the sixth support 2502 along the width direction of the tunnel 6, and the second idler roller 2504 is set between adjacent second support plates through bearings, thereby realizing the rotational setting of multiple second idler rollers 2504 on the sixth support 2502.

[0198] The number of first idler rollers 2503 and second idler rollers 2504 can be set according to actual needs and there is no limit to this. For example, there can be two first idler rollers 2503, which are arranged in a V-shape, and there can be three second idler rollers 2504, which are arranged in a U-shape.

[0199] The spacing between adjacent support devices 25 can be set according to actual needs, and there are no restrictions on it.

[0200] like Figure 10 As shown, in some embodiments, the material injection auxiliary system 3 includes a first material injection device 31 and a second material injection device 32. The first material injection device 31 is installed on the shield machine 7 inside the tunnel 6. The discharge end of the first material injection device 31 faces the surrounding rock and the gap between the tunnel segments of the tunnel 6. The first material injection device 31 is used to inject a third material 101 into the surrounding rock and the gap between the tunnel segments of the tunnel 6. The second material injection device 32 is installed on the shield machine 7. The discharge end of the second material injection device 32 is connected to the feed end of the first material injection device 31. The second material injection device 32 is used to inject a fourth material 102 into the third material 101 according to a ratio.

[0201] Understandably, since the discharge end of the first injection device 31 faces the gap between the surrounding rock and the tunnel segments of the tunnel 6, the first injection device 31 can inject the third material 101 into the gap between the surrounding rock and the tunnel segments of the tunnel 6. Since the discharge end of the second injection device 32 is connected to the feed end of the first injection device 31, the second injection device 32 can inject the fourth material 102 into the third material 101 according to the ratio. Thus, the injection auxiliary system 3 can achieve the mixing of the third material 101 and the fourth material 102 while injecting the third material 101 into the gap between the surrounding rock and the tunnel segments of the tunnel 6, thereby making the injection auxiliary system 3 more flexible and easier to use.

[0202] It should be noted that the mixing ratio of the third material 101 and the fourth material 102 can be set according to actual needs, and there are no restrictions on it.

[0203] The specific types of the first injection device 31 and the second injection device 32 can be set according to actual needs, and there are no restrictions on them.

[0204] like Figure 10 As shown, in some embodiments, the first material injection device 31 may include a first storage tank 3101, a first conveying pump 3102 and a plurality of first material injection pipes 3103. The first storage tank 3101 and the first conveying pump 3102 are respectively installed on the tunnel boring machine 7. The first storage tank 3101 stores a third material 101. The inlet end of the first conveying pump 3102 is connected to the outlet end of the first storage tank 3101, and the outlet end of the first conveying pump 3102 is connected to the first inlet end of the plurality of first material injection pipes 3103.

[0205] Understandably, under the conveying of the first conveying pump 3102, the third material 101 in the first storage tank 3101 is injected from the discharge end of the multiple first injection pipes 3103 into the surrounding rock and the gap between the segments of the tunnel 6.

[0206] It should be noted that the specific type of the first delivery pump 3102 can be set according to actual needs, and there is no restriction on it. For example, the first delivery pump 3102 can be a mortar pump.

[0207] The discharge end of the first conveying pump 3102 can also be connected to the return end of the first storage tank 3101, and an overflow valve is provided between the discharge end of the first conveying pump 3102 and the return end of the first storage tank 3101 to ensure the stable operation of the first injection device 31.

[0208] Switch valves can also be installed at the inlet and outlet ends of the first conveying pump 3102 to make the use of the first injection device 31 more flexible and convenient.

[0209] like Figure 10As shown, in some embodiments, the second material injection device 32 includes a second storage tank 3201, a second conveying pump 3202, and a plurality of second material injection pipes 3203. The second storage tank 3201 and the second conveying pump 3202 are respectively installed on the tunnel boring machine 7. The second storage tank 3201 stores the fourth material 102. The inlet end of the second conveying pump 3202 is connected to the outlet end of the second storage tank 3201. The outlet end of the second conveying pump 3202 is connected to the inlet end of the plurality of second material injection pipes 3203. The outlet ends of the plurality of second material injection pipes 3203 are respectively connected to the second inlet end of the plurality of first material injection pipes 3103.

[0210] Understandably, under the delivery of the second delivery pump 3202, the fourth material 102 in the second storage tank 3201 is injected from the discharge end of the multiple second injection pipes 3203 into the multiple first injection pipes 3103 and mixed with the third material 101.

[0211] like Figure 10 As shown, in some embodiments, the second injection device 32 further includes a plurality of proportional adjustment components 3204, which are respectively disposed on a plurality of second injection pipes 3203. Each proportional adjustment component 3204 includes a proportional valve 32041 and a first flow meter 32042, which are respectively disposed on the second injection pipes 3203, and the first flow meter 32042 is located between the proportional valve 32041 and the first injection pipe 3103.

[0212] It is understandable that by setting the first flow meter 32042, the flow rate of the fourth material 102 in the second injection pipe 3203 can be detected, and by setting the proportional valve 32041, the flow rate of the fourth material 102 in the second injection pipe 3203 can be controlled. Thus, by cooperating with the proportional valve 32041 and the first flow meter 32042, the flow rate of the fourth material 102 in the second injection pipe 3203 can be adjusted, thereby achieving the proportional mixing of the third material 101 and the fourth material 102.

[0213] It should be noted that the proportional valve 32041 controls the flow of the fourth material 102 by adjusting its own opening size. The specific type of the proportional valve 32041 can be set according to actual needs and there are no restrictions on it.

[0214] The first flow meter 32042 is used to detect the flow rate of the fourth material 102 in the second injection pipe 3203. The specific type of the first flow meter 32042 can be set according to actual needs and there is no restriction on it.

[0215] The entire system can be closed-loop controlled using a PID control program from a PLC controller.

[0216] like Figure 10 As shown, in some embodiments, the first injection device 31 further includes a plurality of second flow meters 3104, which are respectively disposed on a plurality of first injection pipes 3103. It is understood that by using the second flow meters 3104, the flow rate of the third material 101 in the first injection pipe 3103 can be detected, thereby enabling the proportional valve 32041 to adjust the flow rate of the fourth material 102 based on the flow rate of the fourth material 102 detected by the first flow meter 32042 and the flow rate of the third material 101 detected by the second flow meters 3104, so as to ensure that the mixing ratio of the third material 101 and the fourth material 102 is maintained within a set range.

[0217] It should be noted that the second flow meter 3104 is used to detect the flow rate of the third material 101 in the first injection pipe 3103. The specific type of the second flow meter 3104 can be set according to actual needs, and there are no restrictions on it.

[0218] The first flow meter 32042, the second flow meter 3104, and the proportional valve 32041 can be controlled in a closed loop by a controller, and there are no restrictions on this.

[0219] like Figure 11 As shown, in some embodiments, the fourth material 102 includes a fifth material in a liquid state and a sixth material in a solid state. The second feeding device 32 also includes a third storage tank 3205, a fourth storage tank 3206, a first feeder 3207, and a second feeder 3208. The third storage tank 3205 stores the fifth material, and the fourth storage tank 3206 stores the sixth material. The feed end of the first feeder 3207 is located in the third storage tank 3205, and the discharge end of the first feeder 3207 is connected to the feed end of the second storage tank 3201. The feed end of the second feeder 3208 is located in the fourth storage tank 3206, and the discharge end of the second feeder 3208 is connected to the feed end of the second storage tank 3201.

[0220] Understandably, since the feed end of the first feeder 3207 is located inside the third storage tank 3205, and the discharge end of the first feeder 3207 is connected to the feed end of the second storage tank 3201, the first feeder 3207 can transport the fifth material in the third storage tank 3205 to the second storage tank 3201. Since the feed end of the second feeder 3208 is located inside the fourth storage tank 3206, and the discharge end of the second feeder 3208 is connected to the feed end of the second storage tank 3201, the second feeder 3208 can transport the sixth material in the fourth storage tank 3206 to the second storage tank 3201. Thus, the fifth and sixth materials are mixed in the second storage tank 3201, thereby enabling the fourth material 102 to be formed and stored in the second storage tank 3201, ensuring the stable mixing of the fourth material 102 and the third material 101.

[0221] It should be noted that the specific types of the fifth and sixth materials can be set according to actual needs, and there are no restrictions on this. For example, the fifth material can be water, and the sixth material can be auxiliary powder of mortar. The auxiliary powder is mixed with water to form an auxiliary liquid.

[0222] The specific types of the first feeder 3207 and the second feeder 3208 can be set according to actual needs, and there are no restrictions on this.

[0223] like Figure 11 As shown, a stirring device 3209 can also be installed inside the second storage tank 3201 to achieve full mixing of the fifth and sixth materials. The specific type of the stirring device 3209 can be set according to actual needs and is not limited thereto. For example, the stirring device 3209 may include a stirring shaft, a stirring motor and multiple stirring blades. The stirring shaft is rotatably installed inside the second storage tank 3201, the stirring motor is installed on the second storage tank 3201, and the output shaft of the stirring motor is connected to the stirring shaft. Multiple stirring blades are installed on the stirring shaft.

[0224] Weighing devices may also be installed at the bottom of the third storage tank 3205 and the fourth storage tank 3206 to enable the fifth and sixth materials to be mixed according to the weight ratio. The specific type of weighing device can be set according to actual needs and is not limited thereto. For example, the weighing device can be a weighing sensor.

[0225] like Figure 10As shown, in some embodiments, the second injection device 32 further includes a water storage tank 3210, a third delivery pump 3211, and a plurality of water injection pipes 3212. The water storage tank 3210 and the third delivery pump 3211 are respectively installed on the tunnel boring machine 7. The water storage tank 3210 stores clean water. The water inlet of the third delivery pump 3211 is connected to the water outlet of the water storage tank 3210. The water outlet of the third delivery pump 3211 is connected to the water inlet of the plurality of water injection pipes 3212. The water outlets of the plurality of water injection pipes 3212 are respectively connected to the second feed inlet of the plurality of first injection pipes 3103.

[0226] Understandably, under the delivery of the third delivery pump 3211, the clean water in the water storage tank 3210 is injected into the first injection pipe 3103 from the outlet of multiple water injection pipes 3212, thereby cleaning the first injection pipe 3103 and avoiding problems such as blockage after injection, thus ensuring the stable operation of the injection auxiliary system 3.

[0227] It should be noted that the first injection pipe 3103, the second injection pipe 3203, the water injection pipe 3212, the first flow meter 32042, the second flow meter 3104, and the proportional valve 32041 correspond one-to-one. The number of the first injection pipe 3103, the second injection pipe 3203, the water injection pipe 3212, the first flow meter 32042, the second flow meter 3104, and the proportional valve 32041 can be set according to actual needs and there is no limitation. For example, the first injection pipe 3103, the second injection pipe 3203, the water injection pipe 3212, the first flow meter 32042, the second flow meter 3104, and the proportional valve 32041 can all be three, four, five, etc.

[0228] A switch valve can also be installed at the outlet of the water inlet pipe 3212 to facilitate the control of the cleaning water.

[0229] like Figure 12 As shown, in some embodiments, the first injection device 31 includes a three-way pipe 3213, which includes a pipe body 32131 and a one-way valve 32132. The first feed end of the pipe body 32131 is used to input the third material 101, and the discharge end of the pipe body 32131 faces the surrounding rock and the gap between the tunnel segments of the tunnel 6. The one-way valve 32132 is installed on the pipe body 32131, and the feed end of the one-way valve 32132 is connected to the discharge end of the second injection device 32, and the discharge end of the one-way valve 32132 is connected to the second feed end of the pipe body 32131.

[0230] Understandably, since the third material 101 is input into the first feed end of the pipe body 32131, and the second feed end of the pipe body 32131 is connected to the discharge end of the second injection device 32, with the discharge end of the pipe body 32131 facing the surrounding rock and the gap between the tunnel segments of the tunnel 6, the third material 101 and the fourth material 102 can be mixed in the pipe body 32131 and injected into the surrounding rock and the gap between the tunnel segments of the tunnel 6 after mixing. This enables flexible injection of the injection auxiliary system 3, making its use more convenient. At the same time, since a one-way valve 32132 is provided between the second feed end of the pipe body 32131 and the discharge end of the second injection device 32, the mixed material in the pipe body 32131 cannot enter the second injection device 32, thus avoiding damage to the second injection device 32 caused by the backflow of the mixed material and ensuring the stable operation of the injection auxiliary system 3.

[0231] It should be noted that the tee pipe 3213 includes a first inlet end, a second inlet end, and an outlet end. The first inlet end and the outlet end of the tee pipe 3213 are arranged opposite each other, and the second inlet end of the tee pipe 3213 is located between the first inlet end and the outlet end of the tee pipe 3213. The specific installation direction of the tee pipe 3213 can be set according to actual needs. For example, the first inlet end of the tee pipe 3213 can be located at the bottom, and the outlet end of the tee pipe 3213 can be located at the top.

[0232] The specific type of the tee pipe 3213 can be set according to actual needs and there are no restrictions on it. For example, the tee pipe 3213 can be the first injection pipe 3103.

[0233] The specific type of check valve 32132 can be set according to actual needs, and there are no restrictions on it.

[0234] like Figure 13 , Figure 14 and Figure 15As shown, in some embodiments, the one-way valve 32132 includes a valve body 321321, a valve stem 321323, a material passage 321324, and an elastic sleeve 321325. The valve body 321321 is disposed on the pipe body 32131, and a valve cavity 321322 is disposed inside the valve body 321321. The valve cavity 321322 is connected to the second feed end of the pipe body 32131. The valve stem 321323 is disposed on the valve body 321321, and the valve stem 321323 includes a first part 3213231 and a second part 3213232. The first part 3213231 is connected to the second part 3213232. Part 3213231 is located outside valve chamber 321322, and part 3213232 is located inside valve chamber 321322. Material passage 321324 is located inside valve column 321323. The inlet end of material passage 321324 is located on part 3213231 and is connected to the outlet end of second injection device 32. The outlet end of material passage 321324 is located on part 3213232. Elastic sleeve 321325 is fitted on part 3213232 and covers the outlet end of material passage 321324. Figure 14 As shown, when the pressure in the material passage 321324 is greater than the pressure in the valve chamber 321322, a gap 321326 is generated between the elastic sleeve 321325 and the second part 3213232. The discharge end of the material passage 321324 is connected to the valve chamber 321322 through the gap 321326. Figure 13 As shown, when the pressure in the material passage 321324 is less than or equal to the pressure in the valve cavity 321322, the elastic sleeve 321325 is sealed and fitted with the second part 3213232, and the discharge end of the material passage 321324 is cut off from the valve cavity 321322.

[0235] Understandably, the fourth material 102 enters from the feed end of the material passage 321324 and fills the interior of the material passage 321324. When the pressure of the fourth material 102 in the material passage 321324 is greater than the pressure of the third material 101 in the valve cavity 321322, the elastic sleeve 321325 deforms under the action of the pressure difference and forms a gap 321326 with the second part 3213232, so that the fourth material 102 in the material passage 321324 is discharged from the discharge end of the material passage 321324 through the gap 321326 into the valve cavity 321322; when the pressure of the fourth material 102 in the material passage 321324 is equal to the pressure of the third material 101 in the valve cavity 321322, the fourth material 102 in the material passage 321324 is discharged from the discharge end of the material passage 321324 through the gap 321326. When the pressure of the third material 101 is less than the pressure of the third material 101 in the valve cavity 321322, the elastic sleeve 321325 seals against the second part 3213232 under its own elastic force, preventing the fourth material 102 in the material passage 321324 from flowing out from the outlet end of the material passage 321324. When the pressure of the fourth material 102 in the material passage 321324 is less than the pressure of the third material 101 in the valve cavity 321322, the elastic sleeve 321325 seals against the second part 3213232 under the combined action of its own elastic force and the pressure of the third material 101 in the valve cavity 321322, preventing the fourth material 102 in the material passage 321324 from flowing out from the outlet end of the material passage 321324.

[0236] Therefore, by utilizing the elastic force of the elastic sleeve 321325 and the pressure difference within the check valve 32132, unidirectional passage of the fourth material 102 is achieved without involving mechanical movement. This not only improves the sealing performance of the check valve 32132 and effectively enhances its performance, but also reduces wear within the check valve 32132 and effectively extends its service life.

[0237] It should be noted that the elastic sleeve 321325 is elastic. The elastic sleeve 321325 can be fitted onto the second part 3213232 by its own elasticity. The specific material of the elastic sleeve 321325 can be set according to actual needs. For example, the elastic sleeve 321325 can be made of rubber material.

[0238] The specific size of the gap 321326 is determined based on the elasticity of the elastic sleeve 321325, the pressure of the fourth material 102 in the material passage 321324, and the pressure of the third material 101 in the valve cavity 321322. The greater the pressure of the fourth material 102 in the material passage 321324, the smaller the elasticity of the elastic sleeve 321325 and the pressure of the third material 101 in the valve cavity 321322, the larger the size of the gap 321326 and the greater the flow rate of the fourth material 102.

[0239] The specific type of valve body 321321 can be set according to actual needs. For example, valve body 321321 can be a cylindrical structure, and valve cavity 321322 is the chamber inside the cylindrical structure.

[0240] The specific types of the first part 3213231 and the second part 3213232 can be set according to actual needs. For example, the first part 3213231 is a cylindrical structure, and the second part 3213232 is a combination of a cylindrical structure and a frustum structure. The diameter of the cylindrical structure of the second part 3213232 is larger than that of the cylindrical structure of the first part 3213231. The frustum structure of the second part 3213232 is used for the connection between the cylindrical structure of the second part 3213232 and the cylindrical structure of the first part 3213231. The valve stem 321323 can be a one-piece molded part.

[0241] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the discharge end of the material passage 321324 is disposed on the outer circumferential surface of the second part 3213232, and the elastic sleeve 321325 is sleeved on the outer circumferential surface of the second part 3213232. The end of the elastic sleeve 321325 near the first part 3213231 is sealed and connected to the second part 3213232. The one-way valve 32132 also includes a first cover plate 321327, which is disposed at the end of the second part 3213232 away from the first part 3213231. The first cover plate 321327 abuts against the end of the elastic sleeve 321325 away from the first part 3213231.

[0242] It is understandable that the fourth material 102 enters from the feed end of the material passage 321324 and fills the interior of the material passage 321324. When the pressure of the fourth material 102 in the material passage 321324 is greater than the pressure of the third material 101 in the valve cavity 321322, the elastic sleeve 321325 deforms under the action of the pressure difference and a gap 321326 is generated between it and the outer circumferential surface of the second part 3213232. Since the end of the elastic sleeve 321325 near the first part 3213231 is sealed and connected to the second part 3213232, the fourth material 102 in the material passage 321324 is discharged from the discharge end of the material passage 321324 along the direction from the first part 3213231 to the second part 3213232 through the gap 321326 into the valve cavity 321322 and mixes with the third material 101.

[0243] This not only enhances the stability of the elastic sleeve 321325 on the second part 3213232, but also reduces the number of bends in the flow path of the fourth material 102, thereby allowing the fourth material 102 to flow more smoothly from the material passage 321324 into the valve chamber 321322, effectively improving the performance of the one-way valve 32132. Furthermore, the first cover plate 321327, when the elastic sleeve 321325 is tightly fitted with the second part 3213232, forms a seal to block the end of the elastic sleeve 321325 away from the first part 3213231, preventing backflow problems in the one-way valve 32132 and further improving the performance of the one-way valve 32132.

[0244] It should be noted that the specific type of the first cover plate 321327 can be set according to actual needs. For example, the shape of the first cover plate 321327 can be the same as the cross-sectional shape of the elastic sleeve 321325, and the size of the first cover plate 321327 can be larger than the cross-sectional size of the elastic sleeve 321325. The first cover plate 321327 can be set at the end of the second part 3213232 away from the first part 3213231 by welding, bolting or other means.

[0245] The arrangement of the material passage 321324 within the valve stem 321323 can be determined according to the shape of the valve stem 321323. For example, the main body of the material passage 321324 can be a cylindrical structure, and the central axis of the material passage 321324 can coincide with the central axis of the valve stem 321323.

[0246] The specific dimensions of the elastic sleeve 321325 can be set according to actual needs. For example, the inner diameter of the elastic sleeve 321325 is smaller than the outer diameter of the second part 3213232.

[0247] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the material passage 321324 is provided with multiple discharge ends, and the discharge ends of the material passage 321324 extend obliquely along the direction from the first part 3213231 to the second part 3213232.

[0248] Understandably, by extending the discharge end of the material passage 321324 at an angle along the direction from the first part 3213231 to the second part 3213232, the bending angle of the bend point on the flow path of the fourth material 102 is made larger. This not only effectively reduces the impact force of the fourth material 102 on the elastic sleeve 321325 and reduces the wear of the elastic sleeve 321325, but also further improves the smoothness of the fourth material 102 being discharged from the material passage 321324 into the valve chamber 321322, effectively improving the performance of the one-way valve 32132.

[0249] It should be noted that the distribution of the multiple discharge ends of the material passage 321324 can be set according to actual needs. For example, the multiple discharge ends of the material passage 321324 are divided into multiple groups. The multiple groups of discharge ends of the material passage 321324 are evenly distributed along the direction from the first part 3213231 to the second part 3213232. The discharge ends in each group are evenly distributed along the circumference of the second part 3213232.

[0250] The specific number and tilt angle of the material passages 321 and 324 can be set according to actual needs, and there are no restrictions on them.

[0251] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the one-way valve 32132 further includes a sealing sleeve 321328, which is sleeved on the second part 3213232 near the end of the first part 3213231, and an elastic sleeve 321325 is disposed between the sealing sleeve 321328 and the second part 3213232 near the end of the first part 3213231.

[0252] It is understandable that by setting the sealing sleeve 321328, the end of the elastic sleeve 321325 near the first part 3213231 can be sealed. The sealing sleeve 321328 is set on the second part 3213232. This not only achieves the seal between the end of the elastic sleeve 321325 near the first part 3213231 and the second part 3213232, ensuring that the fourth material 102 in the material passage 321324 can flow in the gap 321326 along the direction from the first part 3213231 to the second part 3213232, but also cooperates with the first cover plate 321327 to avoid the backflow problem of the one-way valve 32132, further improving the performance of the one-way valve 32132.

[0253] It should be noted that the way the elastic sleeve 321325 is set between the sealing sleeve 321328 and the second part 3213232 can be set according to actual needs. For example, the elastic sleeve 321325 is connected to the sealing sleeve 321328 by adhesive, and the elastic sleeve 321325 is connected to the second part 3213232 by abutment. The distance between the sealing sleeve 321328 and the second part 3213232 is less than the thickness of the elastic sleeve 321325. It is understandable that by abutting the elastic sleeve 321325 against the second part 3213232, the elastic sleeve 321325 and the second part 3213232 are connected, while facilitating disassembly and maintenance between the elastic sleeve 321325 and the second part 3213232. At the same time, the distance between the sealing sleeve 321328 and the second part 3213232 is set to be smaller than the thickness of the elastic sleeve 321325, so that the sealing sleeve 321328 can press the elastic sleeve 321325 onto the second part 3213232, thereby effectively improving the sealing performance between the elastic sleeve 321325 and the second part 3213232.

[0254] The specific type of sealing sleeve 321328 can be set according to actual needs, and there are no restrictions on it.

[0255] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the valve body 321321 is provided with an opening 321329, and the end of the second part 3213232 near the first part 3213231 passes through the opening 321329. The one-way valve 32132 also includes a flange 3213210, which is sealed on the valve body 321321 and covers the opening 321329. The flange 3213210 is sleeved on the end of the first part 3213231 near the second part 3213232.

[0256] Understandably, the installation of openings 321329 and flanges 3213210 not only facilitates the disassembly and assembly of components such as valve stem 321323 and sealing sleeve 321328 inside the valve body 321321, making the inspection and maintenance of the check valve 32132 more convenient, but also ensures the sealing of the valve cavity 321322 and avoids leakage problems.

[0257] It should be noted that the specific dimensions of the opening 321329 can be set according to actual needs, as long as components such as the valve stem 321323 and the sealing sleeve 321328 can pass through smoothly, and there are no restrictions on this.

[0258] The specific type of flange 3213210 can be determined based on opening 321329, and there are no restrictions on it.

[0259] The flange 3213210 can be installed on the valve body 321321 in a manner that can be determined according to actual needs. For example, the flange 3213210 can be installed on the valve body 321321 by means of bolt fixing, snap-fit ​​fixing, etc.

[0260] A sealing element can be provided between flange 3213210 and valve body 321321 as needed. For example, a sealing ring is provided between flange 3213210 and valve body 321321 to further improve the sealing performance of valve cavity 321322.

[0261] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the one-way valve 32132 further includes a retaining sleeve 3213211 and a nut 3213212. The retaining sleeve 3213211 is threadedly fitted onto the end of the second part 3213232 near the first part 3213231. The retaining sleeve 3213211 is located inside the opening 321329. The end of the retaining sleeve 3213211 away from the first part 3213231 is connected to the sealing sleeve 321328. The end of the retaining sleeve 3213211 near the first part 3213231 abuts against the flange 3213210. The nut 3213212 is threadedly fitted onto the end of the first part 3213231 near the second part 3213232. The end of the nut 3213212 near the second part 3213232 abuts against the flange 3213210.

[0262] Understandably, by setting the fixing sleeve 3213211 and nut 3213212, the flange 3213210, valve column 321323 and sealing sleeve 321328 are relatively fixed, while the sealing between valve column 321323 and flange 3213210 is guaranteed, which further improves the sealing performance of valve cavity 321322. This facilitates the disassembly, assembly and maintenance of check valve 32132 while avoiding leakage problems.

[0263] It should be noted that the specific types of the fixing sleeve 3213211 and nut 3213212 can be set according to actual needs, and there are no restrictions on this.

[0264] A sealing element can be provided between the fixed sleeve 3213211 and the flange 3213210 as needed. For example, a sealing ring is provided between the fixed sleeve 3213211 and the flange 3213210 to further improve the sealing performance of the valve cavity 321322.

[0265] When installing the check valve 32132, the elastic sleeve 321325, sealing sleeve 321328, first cover plate 321327 and other components can be placed on the valve stem 321323 firstly. Then, the valve stem 321323 is connected to the flange 3213210 through the fixing sleeve 3213211 and nut 3213212. Finally, the flange 3213210 is placed on the valve body 321321. When removing and repairing the check valve 32132, the operation can be performed in the reverse order.

[0266] The feed end of the material passage 321324 is located at the end of the first part 3213231 that is away from the second part 3213232, such as... Figure 12 and Figure 15 As shown, a quick connector 3213213 is provided on the feed end of the material passage 321324, and the one-way valve 32132 is connected to the discharge end of the second injection device 32 through the quick connector 3213213. The specific type of quick connector 3213213 can be set according to actual needs and is not limited thereto.

[0267] like Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the valve stem 321323 extends obliquely along the direction from the discharge end of the tube body 32131 to the first feed end of the tube body 32131.

[0268] Understandably, by extending the valve stem 321323 of the one-way valve 32132 at an angle from the discharge end of the pipe body 32131 to the first feed end of the pipe body 32131, the impact force of the third material 101 in the pipe body 32131 on the valve stem 321323, the elastic sleeve 321325 and other components is effectively reduced, thereby reducing the wear of the one-way valve 32132 and effectively extending the service life of the three-way pipe 3213.

[0269] It should be noted that the tilt angle of the valve stem 321323 can be set according to actual needs, and there are no restrictions on it.

[0270] like Figure 15 As shown, in some embodiments, the three-way pipe 3213 further includes a first baffle 3213214, which is disposed on the side wall of the pipe body 32131 opposite to the valve column 321323. The first baffle 3213214 is located between the valve column 321323 and the second feed end of the pipe body 32131.

[0271] It is understandable that by setting the first baffle 3213214, part of the third material 101 between the one-way valve 32132 and the second feed end of the pipe body 32131 can be effectively blocked, thereby reducing the impact force of the third material 101 in the pipe body 32131 on the valve column 321323, elastic sleeve 321325 and other components, thereby reducing the wear of the one-way valve 32132 and effectively extending the service life of the three-way pipe 3213.

[0272] It should be noted that, while ensuring that the first baffle 3213214 effectively shields the valve column 321323, elastic sleeve 321325 and other components, the impact on the flow rate of the third material 101 in the pipe body 32131 should be minimized. The specific dimensions of the first baffle 3213214 can be determined based on the dimensions of the pipe body 32131 and the valve column 321323, and there are no restrictions on this.

[0273] The arrangement of the first baffle 3213214 inside the pipe body 32131 can be configured according to actual needs. For example, the first baffle 3213214 can be set on the side wall inside the pipe body 32131 by welding, bolting or other methods.

[0274] Before installing the check valve 32132, the first baffle 3213214 can be installed at the second feed end of the pipe body 32131. When the first baffle 3213214 is removed for maintenance, the operation can be carried out in the reverse order.

[0275] like Figure 15 As shown, in some embodiments, the first baffle 3213214 extends obliquely along the direction from the discharge end of the tube 32131 to the first feed end of the tube 32131, and the first baffle 3213214 bends from the center line of the first baffle 3213214 to both sides of the first baffle 3213214 along the direction from the discharge end of the tube 32131 to the first feed end of the tube 32131.

[0276] Understandably, the inclined arrangement of the first baffle 3213214 within the pipe body 32131 and the bending structure of the first baffle 3213214 itself make the mixture of the third material 101 and the fourth material 102 flow more smoothly from the discharge end of the pipe body 32131 to the first feed end of the pipe body 32131. This avoids the accumulation of the mixture at the one-way valve 32132 due to the presence of the first baffle 3213214 during cleaning of the three-way pipe 3213, thereby providing further protection for the one-way valve 32132 and effectively extending the service life of the three-way pipe 3213.

[0277] The second material handling system 4 can be used to classify, dehydrate, separate and dry the second material 10 such as shield tunnel slag, mud and other waste, and reuse inorganic raw materials and water resources, so as to realize the reduced transportation, environmentally friendly treatment and resource utilization of the second material 10. The specific type of the second material handling system 4 can be set according to actual needs and there are no restrictions on it.

[0278] like Figure 16 and Figure 17 As shown, in some embodiments, the second material handling system 4 includes a screening device 41, a flocculation collection device 42, and a solid-liquid separation device 43. The feed end of the screening device 41 is connected to the discharge end of the material pool 8, the feed end of the flocculation collection device 42 is connected to the second discharge end of the screening device 41, and the feed end of the solid-liquid separation device 43 is connected to the second discharge end of the flocculation collection device 42.

[0279] It is understandable that by setting up the screening device 41, the second material 10 is screened; by setting up the flocculation collection device 42, the second material 10 after screening is flocculated and collected; and by setting up the solid-liquid separation device 43, the second material 10 after flocculation and collection is separated into solid and liquid components. Thus, multiple components in the second material 10 can be separated, thereby not only realizing the processing of the second material 10 and effectively improving the efficiency of the tunnel 6 shield tunneling construction, but also enabling the components separated from the second material 10 to be recycled, thereby reducing the cost of the tunnel 6 shield tunneling construction.

[0280] The excess components separated can be sold externally, turning waste into treasure and creating economic benefits; at the same time, it enables the second material 10 to be processed or transported out quickly, and the material pool 8 at the construction site to be emptied in time, creating conditions for construction.

[0281] It should be noted that the component types in the second material 10 can be set according to actual needs, and there are no restrictions on this. For example, the components in the second material 10 can be soil, water, stones, etc. Among them, stones can be screened out by screening device 41. After removing stones, the soil and water in the second material 10 can be separated by flocculation collection device 42 and solid-liquid separation device 43.

[0282] The specific types of the screening device 41, the flocculation collection device 42, and the solid-liquid separation device 43 can be set according to actual needs, and there are no restrictions on them.

[0283] For example, such as Figure 16As shown, the screening device 41 may include a hopper 4101, a coarse vibrating screen 4102, a fine vibrating screen 4103, a coarse screen cone tank 4104, a first hydrocyclone 4105, a second hydrocyclone 4106, a settling tank 4107, a sand washing machine 4108, etc. The feed end of the hopper 4101 is used to feed the second material 10, and the discharge end of the hopper 4101 is connected to the feed end of the coarse vibrating screen 4102. The hopper 4101 is used to transport the second material 10 to the coarse vibrating screen 4102. The coarse vibrating screen 4102 is used to separate large-diameter sand and gravel with low mud content and slurry with high sand content from the second material 10. The first discharge end of the coarse vibrating screen 4102 is used to discharge large-diameter sand and gravel with low mud content, and the second discharge end of the coarse vibrating screen 4102 is used to discharge... The second discharge end of the coarse vibrating screen 4102 is connected to the feed end of the coarse screen cone 4104, which is used to separate the mud with a lower sand content and the small-diameter sand and gravel with a higher mud content from the second material 10. The first discharge end of the coarse screen cone 4104 is used to discharge the mud with a lower sand content from the second material 10. The first discharge end of the coarse screen cone 4104 is connected to the feed end of the first mud tank 44. The second discharge end of the coarse screen cone 4104 is used to discharge the small-diameter sand and gravel with a higher mud content from the second material 10. The second discharge end of the coarse screen cone 4104 is connected to the feed end of the first hydrocyclone 4105, which is used to separate the small-diameter sand and gravel with a lower mud content and the small-diameter sand and gravel with a higher sand content from the second material 10. The first hydrocyclone 4105, with a low sand content, discharges slurry with a low sand content at its first discharge end. This first discharge end is connected to the inlet end of a settling tank 4107, which separates slurry with a low sand content and small-diameter sand and gravel with a low mud content from the second material 10. The first discharge end of the settling tank 4107 discharges small-diameter sand and gravel with a low mud content. This first discharge end is connected to the inlet end of a coarse screen cone 4104. The second discharge end of the settling tank 4107 discharges slurry with a low sand content. This second discharge end is connected to the inlet end of a first mud tank 44. The second discharge end of the first hydrocyclone 4105 discharges small-diameter sand and gravel with a low mud content. The second discharge end of the flow meter 4105 is connected to the feed end of the sand washing machine 4108. The sand washing machine 4108 is used to separate small-diameter sand and gravel with lower mud content and slurry with lower sand content from the second material 10. The first discharge end of the sand washing machine 4108 is used to discharge small-diameter sand and gravel with lower mud content. The first discharge end of the sand washing machine 4108 is connected to the feed end of the fine vibrating screen 4103. The fine vibrating screen 4103 is used to separate small-diameter sand and gravel with lower mud content and slurry with lower sand content from the second material 10. The first discharge end of the fine vibrating screen 4103 is used to discharge small-diameter sand and gravel with lower mud content. The second discharge end of the fine vibrating screen 4103 is used to discharge slurry with lower sand content. The second discharge end of the fine vibrating screen 4103 is connected to the feed end of the first slurry tank 44.The second discharge end of the sand washing machine 4108 is used to discharge slurry with a lower sand content. The second discharge end of the sand washing machine 4108 is connected to the feed end of the second hydrocyclone 4106. The second hydrocyclone 4106 is used to separate small-diameter sand and gravel with a lower mud content and slurry with a lower sand content from the second material 10. The first discharge end of the second hydrocyclone 4106 is used to discharge slurry with a lower sand content. The first discharge end of the second hydrocyclone 4106 is connected to the feed end of the first slurry tank 44. The second discharge end of the second hydrocyclone 4106 is used to discharge small-diameter sand and gravel with a lower mud content. The second discharge end of the second hydrocyclone 4106 is connected to the feed end of the fine vibrating screen 4103.

[0284] The coarse vibrating screen 4102 is equipped with a first high-pressure spraying device. The coarse vibrating screen 4102 uses the high-pressure water of the first high-pressure spraying device to flush away the mud in the large-diameter sand and gravel, so that the first discharge end of the coarse vibrating screen 4102 discharges large-diameter sand and gravel with a lower mud content.

[0285] The sand washing machine 4108 is equipped with a second high-pressure spray device. The sand washing machine 4108 uses the high-pressure water of the second high-pressure spray device to wash away the mud in the small-diameter sand and gravel, so that the first discharge end of the sand washing machine 4108 discharges small-diameter sand and gravel with a lower mud content.

[0286] like Figure 16 As shown, the overflow end of the first mud tank 44 is connected to the feed end of the second mud tank 45, so that after the first mud tank 44 settles, the mud with a lower sand content will overflow into the second mud tank 45.

[0287] Both the coarse vibrating screen 4102 and the fine vibrating screen 4103 include a vibrating motor, screen frame, screen plate, vibration isolation spring, spraying device, etc. The coarse vibrating screen 4102 can be a double-layer linear vibrating screen, and the fine vibrating screen 4103 can be a single-layer linear vibrating screen.

[0288] For example, such as Figure 16As shown, the flocculation collection device 42 may include a first flocculation tank 4201, a second flocculation tank 4202, a dosing device 4203, etc. The inlet end of the first flocculation tank 4201 is connected to the outlet end of the second mud tank 45 and the outlet end of the dosing device 4203, respectively. The first flocculation tank 4201 is used to separate water with low mud content and mud with low water content from the mud. The first outlet end of the first flocculation tank 4201 is used to discharge water with low mud content. The first discharge end of the first flocculation tank 4201 is connected to the feed end of the second flocculation tank 4202. The second discharge end of the first flocculation tank 4201 is used to discharge mud with a lower moisture content. The second flocculation tank 4202 is used to separate water with a lower mud content and mud with a lower moisture content from the slurry. The first discharge end of the second flocculation tank 4202 is used to discharge water with a lower mud content. The first discharge end of the second flocculation tank 4202 is connected to the feed end of the first clear water tank 46. The second discharge end of the second flocculation tank 4202 is used to discharge mud with a lower moisture content.

[0289] Among them, such as Figure 16 As shown, the overflow end of the first clear water tank 46 is connected to the feed end of the second clear water tank 47, so that after the first clear water tank 46 settles, the water with a lower mud content overflows into the second clear water tank 47.

[0290] The discharge end of the second clear water tank 47 can be connected to the inlet end of the first high-pressure spray device and the inlet end of the second high-pressure spray device to realize the recycling of water and thus reduce the overall cost.

[0291] For example, such as Figure 16 As shown, the solid-liquid separation device 43 may include a filter press 4301, etc. The feed end of the filter press 4301 is connected to the second discharge end of the first flocculation tank 4201 and the second discharge end of the second flocculation tank 4202, respectively. The filter press 4301 is used to separate mud with lower water content and water with lower mud content from the slurry. The first discharge end of the filter press 4301 is used to discharge mud with lower water content, and the second discharge end of the filter press 4301 is used to discharge water with lower mud content. The second discharge end of the filter press 4301 is connected to the feed end of the second clear water tank 47.

[0292] Among them, the large-diameter sand and gravel discharged from the first discharge end of the coarse vibrating screen 4102 can be used as construction aggregate for the construction of tunnel 6 or for other fields; the small-diameter sand and gravel discharged from the first discharge end of the fine vibrating screen 4103 can be used as casting raw material for the construction of tunnel 6 or for other fields; the mud discharged from the first discharge end of the filter press 4301 can be used for the construction of tunnel 6 or for other fields; and the water in the second clear water pool 47, in addition to supplying the first high-pressure spray device and the second high-pressure spray device, can also be used for the construction of tunnel 6 or for other fields.

[0293] like Figure 17 , Figure 20 , Figure 21 and Figure 22 As shown, in some embodiments, the third continuous conveying system 5 includes a base 51, a third drive device 54, a collecting device 52, and a lifting device 53. The base 51 is slidably disposed in the material pool 8 in the horizontal direction. The third drive device 54 is connected to the base 51 in a transmission manner and is used to drive the base 51 to reciprocate within the material pool 8. The collecting device 52 is disposed on the base 51, and the feed end of the collecting device 52 is disposed below the material surface of the material pool 8. The lifting device 53 is disposed on the base 51, and the feed end of the lifting device 53 is connected to the discharge end of the collecting device 52. The discharge end of the lifting device 53 is disposed outside the material pool 8 or the discharge end of the lifting device 53 is connected to the feed end of the screening device 41.

[0294] It is understandable that the collecting device 52 collects the second material 10 in the material pool 8 and then conveys it to the lifting device 53. The lifting device 53 lifts the second material 10 out of the material pool 8, thereby realizing the continuous outward conveying of the second material 10 in the material pool 8. The collecting device 52 and the lifting device 53 move back and forth in the material pool 8 with the base 51, so that the feeding of the collecting device 52 can cover the entire area in the material pool 8. Thus, the conveying efficiency of the second material 10 is effectively improved and the conveying cost of the second material 10 is reduced.

[0295] It should be noted that the material pool 8 is used to temporarily store the second material 10. The specific shape of the material pool 8 can be set according to actual needs and there are no restrictions. For example, the material pool 8 can be a cuboid structure, and the moving direction of the base 51 is located in the length direction or the width direction of the material pool 8.

[0296] When the third continuous conveying system 5 conveys the second material 10 from the material pool 8 to the outside, the carriage of the transport vehicle can be placed below the discharge end of the lifting device 53. After the carriage of the transport vehicle is filled, the operation of the lifting device 53 can be stopped briefly to facilitate the replacement of the transport vehicle.

[0297] When the third continuous conveying system 5 conveys the second material 10 from the material pool 8 to the screening device 41, an inclined chute can be set on the moving path of the discharge end of the lifting device 53. The lower end of the chute is located above the feed end of the screening device 41 so that the second material 10 in the material pool 8 can be continuously fed to the screening device 41.

[0298] The third continuous conveying system 5 and the second material handling system 4 can be used simultaneously or separately. When used separately, the third continuous conveying system 5 can transport the second material 10 to the outside, while the feeding of the second material handling system 4 can be completed by equipment such as excavators.

[0299] The specific type of base 51 can be set according to actual needs and there are no restrictions on it. For example, base 51 can be a flat plate structure with a certain strength.

[0300] like Figure 17 As shown, in some embodiments, the material collection device 52 includes a material collection seat 5201, a screw conveyor 5202, and a material collection bin 5203. The material collection seat 5201 is disposed on the base 51, the screw conveyor 5202 is disposed on the material collection seat 5201, and the feed end of the screw conveyor 5202 is disposed below the material surface of the material pool 8. The material collection bin 5203 is disposed on the material collection seat 5201, the feed end of the material collection bin 5203 is connected to the discharge end of the screw conveyor 5202, and the discharge end of the material collection bin 5203 is connected to the feed end of the lifting device 53.

[0301] Understandably, the screw conveyor 5202 collects the second material 10 in the material pool 8 into the collection bin 5203 by screw conveying. The collection bin 5203 guides the collected second material 10 into the lifting device 53 to ensure efficient conveying of the second material 10 by the lifting device 53. At the same time, the screw conveyor 5202 enables continuous collection of the second material 10 in the material pool 8, effectively improving the conveying efficiency of the second material 10 and reducing the conveying cost of the second material 10.

[0302] It should be noted that the specific type of the aggregate holder 5201 can be set according to actual needs, and there is no restriction on it. For example, the aggregate holder 5201 can be a flat plate structure with a certain strength. The aggregate holder 5201 can be set on the base 51 by bolt fixing, welding fixing or other methods.

[0303] The specific type of the collection bin 5203 can be set according to actual needs, and there are no restrictions on it. For example, the collection bin 5203 is a hollow tubular structure. The collection bin 5203 can be set on the collection seat 5201 by means of bolt fixing, welding fixing, etc. The feeding end of the collection bin 5203 can be a bucket-shaped structure.

[0304] like Figure 17 , Figure 21 and Figure 22As shown, in some embodiments, the screw conveyor 5202 includes a first screw blade 52021, a second screw blade 52022, and a third drive member 52023. The first screw blade 52021 is rotatably mounted on the collecting base 5201, and the rotation center axis of the first screw blade 52021 is perpendicular to the moving direction of the base 51. The first screw blade 52021 is located below the material surface of the material pool 8. The second screw blade 52022 is rotatably mounted on the collecting base 5201, and the rotation center axis of the second screw blade 52022 is perpendicular to the moving direction of the base 51. 22 is located below the material surface of the material pool 8. The feed end of the collection bin 5203 is located between the first spiral blade 52021 and the second spiral blade 52022. The third drive member 52023 is disposed on the collection seat 5201. The third drive member 52023 is connected to the first spiral blade 52021 and the second spiral blade 52022. The third drive member 52023 is used to drive the first spiral blade 52021 and the second spiral blade 52022 to rotate, so that the first spiral blade 52021 and the second spiral blade 52022 spiral forward in a direction close to the feed end of the collection bin 5203.

[0305] Understandably, driven by the third driving component 52023, the first spiral blade 52021 and the second spiral blade 52022 rotate and convey the second material 10 on both sides of the base 51 to the feed end of the collection bin 5203, thereby collecting the second material 10 in the material pool 8 and ensuring the efficient conveying of the second material 10 by the lifting device 53. As the first spiral blade 52021 and the second spiral blade 52022 continuously convey the second material 10 on both sides of the base 51 to the feed end of the collection bin 5203 under the drive of the third driving component 52023, and the first spiral blade 52021 and the second spiral blade 52022 reciprocate with the base 51 in the material pool 8, the entire area of ​​the material pool 8 is covered, effectively improving the collection quality and efficiency of the collection device 52 for the second material 10, thereby improving the conveying efficiency of the second material 10 and reducing the conveying cost of the second material 10.

[0306] It should be noted that the arrangement of the first helical blade 52021 and the second helical blade 52022 on the collecting base 5201 can be configured according to actual needs and is not limited thereto. For example, a first support plate is provided at one end of the collecting base 5201, a second support plate is provided at the other end of the collecting base 5201, and a support base is provided in the middle of the collecting base 5201. The first helical blade 52021 is rotatably disposed between the first support plate and the support base through a sealed bearing, and the second helical blade 52022 is rotatably disposed between the second support plate and the support base through a sealed bearing. The first helical blade 52021 and the second helical blade 52022 are coaxially connected in the support base, and the helical directions of the first helical blade 52021 and the second helical blade 52022 are opposite.

[0307] The specific types of the first helical blade 52021 and the second helical blade 52022 can be set according to actual needs and are not limited thereto. For example, the first helical blade 52021 and the second helical blade 52022 can both be an integral structure; the first helical blade 52021 and the second helical blade 52022 can both be a multi-segment combined structure, and the multi-segment combined structure can adapt to different sizes of material pools 8.

[0308] The specific type of the third driving component 52023 can be set according to actual needs and is not limited thereto. For example, the third driving component 52023 includes a hydraulic motor, a first gear and a second gear. The hydraulic motor is mounted on the support base, the first gear is sleeved on the output shaft of the hydraulic motor, and the second gear is sleeved on the rotating shaft of the first helical blade 52021 or the second helical blade 52022. The first gear meshes with the second gear, thereby achieving synchronous rotation of the first helical blade 52021 and the second helical blade 52022 under the drive of the hydraulic motor.

[0309] The arrangement of the collection bin 5203 on the collection seat 5201 can be configured according to actual needs and is not limited thereto. For example, the collection bin 5203 is located in the middle of the collection seat 5201, with the feed end of the collection bin 5203 facing between the first spiral blade 52021 and the second spiral blade 52022, and the discharge end of the collection bin 5203 facing the feed end of the lifting device 53.

[0310] When the screw conveyor 5202 conveys the second material 10, the screw conveyor 5202 also moves back and forth in the material pool 8 along with the base 51. This allows the second material 10 located on the side of the screw conveyor 5202 facing away from the moving direction of the base 51 to be effectively conveyed by adhering to the screw conveyor 5202 under the action of resistance. However, due to the movement of the base 51 and the centrifugal force of the screw conveyor, the second material 10 located on the side of the screw conveyor 5202 facing the moving direction of the base 51 is difficult to adhere to the screw conveyor 5202, resulting in low overall conveying efficiency of the screw conveyor 5202 for the second material 10.

[0311] like Figure 17 , Figure 18 , Figure 19 , Figure 21 and Figure 22 As shown, in some embodiments, the collecting device 52 further includes a second baffle 5204, which is detachably mounted on the collecting seat 5201 and is located on the side of the screw conveyor 5202 facing the moving direction of the base 51.

[0312] It is understandable that by setting the second baffle 5204, the second material 10 located on the side of the screw conveyor 5202 facing the base 51 in the direction of movement can be effectively limited, so that the second material 10 located on the side of the screw conveyor 5202 facing the base 51 in the direction of movement can be attached to the screw conveyor 5202 and effectively conveyed, thereby effectively improving the overall conveying efficiency of the screw conveyor 5202 for the second material 10, thereby improving the conveying efficiency of the second material 10 and reducing the conveying cost of the second material 10.

[0313] It should be noted that the side of the screw conveyor 5202 facing the moving direction of the base 51 and the side facing away from the moving direction of the base 51 are in opposite positions on the screw conveyor 5202. This can be further explained by observing the screw conveyor 5202 passing through a certain position. When the screw conveyor 5202 moves with the base 51, the side of the screw conveyor 5202 facing away from the moving direction of the base 51 passes through the position first, and then the side of the screw conveyor 5202 facing the moving direction of the base 51 passes through the position. Thus, the side of the screw conveyor 5202 facing the moving direction of the base 51 and the side facing away from the moving direction of the base 51 can be determined by the order in which they pass through the position.

[0314] The specific type of the second baffle 5204 can be set according to actual needs and is not limited thereto. For example, the second baffle 5204 can be a flat plate structure with a certain strength. In particular, due to the presence of the collection bin 5203, an avoidance gap can be set near the collection bin 5203 of the second baffle 5204 to avoid collision between the second baffle 5204 and the collection bin 5203.

[0315] like Figure 18 and Figure 19 As shown, in some embodiments, the collecting device 52 further includes a first chute 5205, a second chute 5206, and a lifting device 5207. The first chute 5205 is disposed on the collecting base 5201 and is located on one side of the screw conveyor 5202. The second chute 5206 is disposed on the collecting base 5201 and is located on the other side of the screw conveyor 5202. The lifting device 5207 is disposed on the base 51. The lifting end of the lifting device 5207 is detachably connected to the second baffle 5204. The lifting device 5207 is used to place the second baffle 5204 in the first chute 5205 or the second chute 5206.

[0316] It is understandable that, due to the reciprocating movement of the base 51 within the material pool 8, the direction of movement of the base 51 is constantly changing. Therefore, by hoisting the second baffle 5204 within the first chute 5205 or the second chute 5206 through the hoisting device 5207, the second baffle 5204 can always be located on the side of the screw conveyor 5202 facing the direction of movement of the base 51, thus ensuring that the second baffle 5204 effectively improves the conveying efficiency of the screw conveyor 5202.

[0317] The first chute 5205 and the second chute 5206 facilitate the stable setting and position adjustment of the second baffle 5204 on the collection seat 5201. The hoisting device 5207 facilitates the disassembly and assembly of the second baffle 5204, making the use of the second baffle 5204 more convenient.

[0318] It should be noted that the arrangement of the first slide groove 5205 and the second slide groove 5206 can be configured according to actual needs and is not limited thereto. For example, both the first slide groove 5205 and the second slide groove 5206 are formed on the opposite sides of the first support plate and the second support plate. The upper ends of both the first slide groove 5205 and the second slide groove 5206 can be configured as a bucket-shaped structure to allow the second baffle 5204 to quickly align with the first slide groove 5205 and the second slide groove 5206.

[0319] The specific type of hoisting device 5207 can be set according to actual needs and is not limited thereto. For example, hoisting device 5207 includes a hanger 52071, a telescopic boom 52072 and a chain hoist 52073. The hanger 52071 is set on the base 51, the telescopic boom 52072 is set on the top of the hanger 52071, and the chain hoist 52073 is set on the telescopic end of the telescopic boom 52072. A hanging ring is provided in the middle of the second baffle 5204.

[0320] When the second baffle 5204 is positioned in the first slide groove 5205, the hook of the chain hoist 52073 is moved above the hanging ring by controlling the extension and retraction of the telescopic arm 52072. Then, the hook is moved to the hanging ring by controlling the lifting and lowering of the hook of the chain hoist 52073. The hook is then hooked onto the hanging ring. The second baffle 5204 is moved out of the first slide groove 5205 by controlling the lifting and lowering of the hook of the chain hoist 52073. Then, the second baffle 5204 is moved above the second slide groove 5206 by controlling the extension and retraction of the telescopic arm 52072. Finally, the second baffle 5204 is moved into the second slide groove 5206 by controlling the lifting and lowering of the hook of the chain hoist 52073. This achieves the position adjustment of the second baffle 5204.

[0321] The specific type of telescopic boom 52072 can be set according to actual needs and is not limited thereto. For example, telescopic boom 52072 can be a sliding telescopic boom 52072; telescopic boom 52072 can be a sleeve-type telescopic boom 52072.

[0322] The 52073 chain hoist is a light and small lifting device. The 52073 chain hoist typically includes a motor, sprocket, etc. The specific type of the 52073 chain hoist can be set according to actual needs and there are no restrictions on it.

[0323] To reduce the erosion of the telescopic boom 52072 and chain hoist 52073 by the second material 10, for example, both the telescopic boom 52072 and the chain hoist 52073 are positioned above the material surface of the material pool 8.

[0324] like Figure 17 , Figure 20 , Figure 21 and Figure 22As shown, in some embodiments, the lifting device 53 includes a lifting frame 5301, a drive sprocket 5302, a driven sprocket 5303, a transmission chain 5304, multiple scrapers 5305, a partition plate 5306, and a fourth driving member 5307. The lifting frame 5301 is mounted on the base 51. The drive sprocket 5302 is rotatably mounted at one end of the lifting frame 5301, and the driven sprocket 5303 is rotatably mounted at the end of the lifting frame 5301 away from the drive sprocket 5302. The transmission chain 5304 is wound around the drive sprocket 5302 and the driven sprocket 5303. One end of the transmission chain 5304 is located near the discharge end of the collecting device 52. The other end of the drive chain 5304 is located outside the material pool 8. The drive chain 5304 includes an upper chain and a lower chain. Multiple scrapers 5305 are sequentially arranged on the drive chain 5304. A partition plate 5306 is arranged on the lifting frame 5301 and is located between the upper chain and the lower chain. The scraper 5305 on the upper chain is slidably connected to the partition plate 5306. A fourth drive member 5307 is arranged on the lifting frame 5301 and is connected to the drive sprocket 5302. The fourth drive member 5307 is used to drive the drive sprocket 5302 to rotate so that the upper chain moves towards the outside of the material pool 8 along the discharge end of the collecting device 52.

[0325] Understandably, the fourth driving component 5307 drives the active sprocket 5302 to rotate, and with the cooperation of the driven sprocket 5303, the active sprocket 5302 can drive the transmission chain 5304 to rotate, thereby causing multiple scrapers 5305 to move synchronously with the transmission chain 5304. Due to the setting of the partition 5306, the second material 10 can be limited on the scraper 5305, thereby enabling the scraper 5305 to effectively lift and convey the second material 10. Thus, with the cooperation of the fourth driving component 5307, the partition 5306, and multiple scrapers 5305, continuous lifting and conveying of the second material 10 is achieved, effectively improving the conveying efficiency of the second material 10 and reducing the conveying cost of the second material 10.

[0326] It should be noted that the specific type of the lifting frame 5301 can be set according to actual needs and is not limited thereto. For example, the lifting frame 5301 can be a near-triangular frame structure. The way the lifting frame 5301 is set on the base 51 can also be set according to actual needs and is not limited thereto. For example, the lifting frame 5301 can be set on the base 51 by bolt fixing, welding fixing, or other methods.

[0327] The arrangement of the drive sprocket 5302 and the driven sprocket 5303 on the lifting frame 5301 can be configured according to actual needs and is not limited thereto. For example, the drive sprocket 5302 is rotatably mounted on the upper end of the lifting frame 5301 via a sealed bearing, and the driven sprocket 5303 is rotatably mounted on the lower end of the lifting frame 5301 via a sealed bearing. Correspondingly, the fourth drive member 5307 is also mounted on the upper end of the lifting frame 5301. This makes both the drive sprocket 5302 and the fourth drive member 5307 positioned above the material surface of the material pool 8, thereby reducing the erosion of the second material 10 on the drive sprocket 5302 and the fourth drive member 5307.

[0328] The arrangement of the scraper 5305 on the transmission chain 5304 can be customized according to actual needs and is not limited thereto. For example, the transmission chain 5304 includes multiple links that are hinged together sequentially. The scraper 5305 includes a first part 3213231 and a second part 3213232. The first part 3213231 and the second part 3213232 are respectively fixed on both sides of the link by welding, bolts, or other methods. The link and the connection between the link and the first part 3213231 and the second part 3213232 can be designed as a sealed structure to form a sealed whole structure, preventing material leakage when the scraper 5305 is conveying the second material 10.

[0329] The specific type of the fourth drive component 5307 can be set according to actual needs and is not limited thereto. For example, the fourth drive component 5307 includes a motor and a reducer. The motor and reducer are mounted on the lifting frame 5301. The output shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is coaxially connected to the rotating shaft of the drive sprocket 5302. Thus, the drive sprocket 5302 is rotated under the drive of the motor.

[0330] like Figure 20 As shown, in some embodiments, the lifting device 53 further includes a first side plate 5308, a second side plate 5309, and a second cover plate 5310. The first side plate 5308 is disposed on one side of the partition plate 5306, the second side plate 5309 is disposed on the side of the partition plate 5306 away from the first side plate 5308, and the second cover plate 5310 is disposed on the side of the first side plate 5308 and the second side plate 5309 away from the partition plate 5306. The partition plate 5306, the first side plate 5308, the second side plate 5309, and the second cover plate 5310 together form a material lifting channel. The scraper 5305 located on the upper chain is located inside the material lifting channel, and the scraper 5305 located on the upper chain is slidably and sealingly connected to the inner wall of the material lifting channel.

[0331] It is understandable that by setting the first side plate 5308, the second side plate 5309, and the second cover plate 5310, the scraper 5305 located on the upper chain is placed in a closed material lifting channel. Since the scraper 5305 located on the upper chain is slidably and sealed to the inner wall of the material lifting channel, a sealed space is formed on the scraper 5305 that moves with the scraper 5305. Thus, when the scraper 5305 conveys the second material 10, leakage of the second material 10 can be effectively prevented, ensuring the effective conveying of the second material 10 by the scraper 5305, effectively improving the conveying efficiency of the second material 10, and reducing the conveying cost of the second material 10.

[0332] It should be noted that the arrangement of the partition 5306, the first side plate 5308, the second side plate 5309, and the second cover plate 5310 can be configured according to actual needs, and there are no restrictions on this. For example, the partition 5306, the first side plate 5308, the second side plate 5309, and the second cover plate 5310 are connected by bolts, welding, or other means, and the partition 5306 and the second cover plate 5310 are arranged in parallel, the first side plate 5308 and the second side plate 5309 are arranged in parallel, and both the first side plate 5308 and the second side plate 5309 are perpendicular to the partition 5306 and the second cover plate 5310.

[0333] like Figure 20 As shown, in some embodiments, the lifting device 53 further includes an elastic element 5311, which is disposed in the circumferential direction of the scraper 5305 and abuts against the inner wall of the lifting channel.

[0334] It is understandable that by setting the elastic element 5311, the scraper 5305 can move in the material lifting channel while sealing the scraper 5305 with the material lifting channel, thereby preventing the leakage of the second material 10, ensuring the effective conveying of the second material 10 by the scraper 5305, effectively improving the conveying efficiency of the second material 10, and reducing the conveying cost of the second material 10.

[0335] It should be noted that the specific type of elastic element 5311 can be set according to actual needs, and there are no restrictions on it. For example, elastic element 5311 can be made of polymer materials such as rubber or polyurethane resin.

[0336] The elastic element 5311 abutting against the inner wall of the material lifting channel means that the elastic element 5311 abuts against the partition 5306, the first side plate 5308, the second side plate 5309, and the second cover plate 5310 respectively.

[0337] The way the elastic element 5311 is set on the scraper 5305 can be set according to actual needs, and there is no limitation. For example, the elastic element 5311 can be set in the circumferential direction of the scraper 5305 by means of adhesive fixation, snap-fit ​​fixation, spring adjustable pressing, etc.

[0338] like Figure 21 and Figure 22 As shown, in some embodiments, the third driving device 54 includes a driving base 5401, a winding roller 5402, a fifth driving member 5403, a second steering wheel 5404, and a transmission rope 5405. The driving base 5401 is disposed at one end of the material pool 8. The winding roller 5402 is rotatably disposed on the driving base 5401, and the rotation center axis of the winding roller 5402 is perpendicular to the movement direction of the base 51. The fifth driving member 5403 is disposed on the driving base 5401 and is connected to the winding roller 5402 in a transmission manner. The second steering wheel 5404 is rotatably disposed at one end of the material pool 8 away from the driving base 5401. One end of the transmission rope 5405 is wound around the winding roller 5402, and the other end of the transmission rope 5405 passes around the second steering wheel 5404 and is wound around the winding roller 5402. The two ends of the transmission rope 5405 are wound in opposite directions on the winding roller 5402. The base 51 is connected to the transmission rope 5405.

[0339] Understandably, the fifth driving component 5403 drives the roller 5402 to rotate, so that the roller 5402 winds one end of the transmission rope 5405 and releases the other end of the transmission rope 5405, thereby causing the transmission rope 5405 to drive the base 51 to move, thus realizing the reciprocating movement of the base 51 in the material pool 8.

[0340] The drive mechanism, which uses the cooperation of components such as the roller 5402 and the second steering wheel 5404 to form a transmission rope 5405 to drag the base 51, enables the base 51 to move back and forth while accommodating the large weight of the base 51 and its components such as the material collection device 52 and the lifting device 53, thus ensuring the stable movement of the base 51.

[0341] It should be noted that the way the drive seat 5401 is set on the material pool 8 can be set according to actual needs, and there is no restriction on it. For example, the drive seat 5401 is set on the ground at one end of the material pool 8 by bolt fixing.

[0342] The specific type of the roller 5402 can be set according to actual needs and there is no limitation thereto. For example, the roller 5402 may include a first roller body and a second roller body. The first roller body and the second roller body are coaxially connected and rotatably mounted on the drive seat 5401 through bearings. One end of the transmission rope 5405 is wound on the first roller body and the other end of the transmission rope 5405 is wound on the second roller body.

[0343] The specific type of the fifth drive component 5403 can be set according to actual needs and is not limited thereto. For example, the fifth drive component 5403 includes a motor and a reducer. The motor and reducer are mounted on the drive base 5401. The output shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is coaxially connected to the rotating shaft of the roller 5402. Thus, the roller 5402 is rotated under the drive of the motor.

[0344] The second steering wheel 5404 is used to steer the transmission rope 5405. The specific type of the second steering wheel 5404 can be set according to actual needs and there is no limitation. For example, multiple second steering wheels 5404 can be set. The second steering wheel 5404 is rotatably set at the end of the material pool 8 away from the drive seat 5401 through the bearing. The rotation center axis of the second steering wheel 5404 is perpendicular to the movement direction of the base 51.

[0345] The specific type of transmission rope 5405 can be set according to actual needs and is not limited thereto. For example, transmission rope 5405 can be a rope with tensile strength such as steel wire rope, or a chain 5304 with tensile strength, etc.

[0346] To reduce the erosion of the second material 10 on the third drive device 54, for example, the drive seat 5401, the roller 5402, the fifth drive member 5403, the second steering wheel 5404 and the transmission rope 5405 are all arranged above the material surface of the material pool 8.

[0347] like Figure 17 , Figure 21 and Figure 22 As shown, in some embodiments, the third continuous conveying system 5 further includes a stack 55, a third guide rail 56, and a rotating wheel 57. The stack 55 is disposed on the material pool 8, the discharge end of the lifting device 53 is located above the stack 55, the third guide rail 56 is disposed at the bottom of the stack 55, and the rotating wheel 57 is rotatably disposed on the base 51, with a gap 58 between the rotating wheel 57 and the base 51. The third guide rail 56 passes through the gap 58 and is rotatably connected to the rotating wheel 57.

[0348] Understandably, the third guide rail 56 is set on the material pool 8 via the stack 55, and the third guide rail 56 and the rotating wheel 57 roll together to realize the sliding setting of the base 51 in the material pool 8, ensuring that the base 51 can move back and forth in the material pool 8, thereby enabling the feeding of the material collecting device 52 to cover the entire area in the material pool 8, effectively improving the conveying efficiency of the second material 10 and reducing the conveying cost of the second material 10.

[0349] The trestle 55 provides a driving channel for transport vehicles. Since the discharge end of the lifting device 53 is located above the trestle 55, the transport vehicles can receive the second material 10 discharged by the lifting device 53 while driving on the trestle 55. Thus, the transport vehicles can receive and transport the second material 10, ensuring the efficient outward delivery of the second material 10.

[0350] It should be noted that the specific type of the walkway 55 can be set according to actual needs and there is no limitation. For example, the walkway 55 may include multiple longitudinal beams, multiple transverse beams and a support plate. The ends of the longitudinal beams are set on the ground at the end of the material pool 8, the multiple transverse beams are respectively set between the multiple longitudinal beams, and the support plate is set on the multiple longitudinal beams and multiple transverse beams. Transport vehicles travel on the support plate.

[0351] Alternatively, depending on actual needs, a third guide rail 56 can be separately installed above the material pool 8, while the walkway 55 is set on the ground on the side of the material pool 8, or the walkway 55 can be omitted and the transport vehicles can drive directly on the ground on the side of the material pool 8.

[0352] The specific number of the third guide rail 56 and the rotating wheel 57 can be set according to actual needs and there is no limit to it. For example, the number of the third guide rail 56 and the rotating wheel 57 can be two, three, four, etc.

[0353] To reduce the erosion of components such as the second material 10 on the walkway 55, the third guide rail 56, and the wheel 57, for example, the walkway 55, the third guide rail 56, and the wheel 57 can all be set above the material surface of the material pool 8.

[0354] In the description of this disclosure, the terms "second," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
