During TBM excavation, the support shoes provide stable support for the tunnel boring machine to ensure that the cutterhead of the tunnel boring machine has a normal excavation posture. During the excavation process, due to the complex and changeable geological conditions, it is necessary to advance the detection of unfavorable geological sections when approaching unfavorable geological sections to reduce construction risks and construction difficulties. However, advance detection cannot detect all unfavorable geological conditions. It often happens that during TBM construction, the surrounding rock at the support shoe position is broken and cavities appear, which makes it impossible for the surrounding rock to provide support pressure and propulsion reaction force to the TBM support shoe.

[0036] As mentioned in the background technology, full-face hard rock tunnel boring machines (TBM) are currently widely used in tunnel projects such as railways, highways, mining, and hydropower construction. During TBM excavation, the support shoes provide stable support for the tunnel boring machine to ensure that the cutter head of the tunnel boring machine has a normal excavation posture. During the excavation process, due to the complex and changeable geological conditions, when approaching a poor geological section, it is necessary to advance the detection of the poor geological section to reduce construction risks and construction difficulties. However, advance detection cannot detect all poor geological conditions. It often happens that during TBM construction, the surrounding rock at the support shoe position is broken and cavities appear, which makes it impossible for the surrounding rock to provide support pressure and propulsion reaction force to the TBM support shoe. Therefore, mold sealing grouting is required.

[0037] At present, during TBM construction, when encountering unfavorable geological conditions such as broken surrounding rock, soft rock, collapsed cavity, etc. at the TBM support shoe location, the manual sealing and grouting method is adopted.

[0038] However, manual mold sealing and grouting construction has low efficiency and involves high-altitude operations during the construction process, posing great safety hazards.

[0039] In order to solve the technical problems of low efficiency of sealing and grouting of the existing TBM support shoe part and great safety hazards, the present application proposes an advanced molding device and TBM for the TBM support shoe part, wherein the advanced molding device for the TBM support shoe part includes a monitoring system, a template installation system and a grouting system; the monitoring system is arranged on the main beam of the TBM, the monitoring system includes a camera and a display, the camera is electrically connected to the display, the camera is used to photograph the hole wall to be supported by the TBM support shoe, and the display is used to display the content photographed by the camera; the template installation system includes a grouting template and a template displacement assembly, the template displacement assembly is arranged on the main beam, the output end of the template displacement assembly is connected to the grouting template, and the template displacement assembly is configured to drive the grouting template to move so that the grouting template closes the hole wall to be grouted; the grouting system includes a nozzle and a nozzle displacement assembly, the nozzle displacement assembly is arranged on the main beam, the output end of the nozzle displacement assembly is connected to the nozzle, the nozzle displacement assembly is configured to drive the nozzle to move so that the nozzle is aligned with the grouting port of the grouting template, and the nozzle is used to pour concrete.

[0040] The advance molding device for the TBM support shoe part of the present application first observes the condition of the cave wall to be supported by the support shoe of the TBM through the monitoring system. If there is a cavity in the cave wall to be supported and the surrounding rock is detached, the grouting template is used to seal the cave wall at this position through the template installation system, and then the concrete is poured into the grouting port of the grouting template through the grouting system to achieve the sealing grouting of the cave wall at this position, completing the advance support, and facilitating the subsequent TBM support shoe part to support this place. Since the present application observes the cave wall to be supported by the support shoe of the TBM in advance through the monitoring system, there is no need for manual observation here, which improves the observation efficiency, ensures personal safety, and reduces safety hazards; at the same time, the template installation system and the grouting system are used to perform sealing grouting, which further improves the efficiency of sealing grouting compared to manual construction, reduces the high intensity of construction personnel, and ensures the personal safety of workers.

[0041] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] Reference Figures 1 to 8 As shown, Figure 1 A schematic structural diagram of an advance molding device for a TBM support shoe provided in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure from another angle; Figure 3Another structural schematic diagram of the advance molding device for the TBM support shoe part provided in the embodiment of the present application; Figure 4 for Figure 1 Structural diagram of the middle template installation system; Figure 5 for Figure 4 A schematic diagram of the structure from another angle; Figure 6 for Figure 2 Schematic diagram of the structure of the grouting system; Figure 7 for Figure 2 The structural diagram of the monitoring system; Figure 8 A schematic structural diagram of an operating room in an advance molding device for a TBM support shoe portion provided in an embodiment of the present application.

[0043] In the embodiments of this application, refer to Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present application provides an advanced molding device for a TBM support shoe part, comprising a monitoring system 100, a template installation system 200 and a grouting system 300.

[0044] The monitoring system 100 is used to be set on the main beam 400 of the TBM. The monitoring system 100 includes a camera 110 and a display 120. The camera 110 is electrically connected to the display 120. The camera 110 is used to photograph the cave wall supported by the support shoe 500 of the TBM, and the display 120 is used to display the content photographed by the camera 110.

[0045] The template installation system 200 includes a grouting template 210 and a template displacement assembly 220. The template displacement assembly 220 is used to be set on the main beam 400. The output end of the template displacement assembly 220 is connected to the grouting template 210. The template displacement assembly 220 is configured to drive the grouting template 210 to move so that the grouting template 210 closes the hole wall to be grouted.

[0046] The grouting system 300 includes a nozzle 310 and a nozzle displacement assembly 320. The nozzle displacement assembly 320 is used to be set on the main beam 400. The output end of the nozzle displacement assembly 320 is connected to the nozzle 310. The nozzle displacement assembly 320 is configured to drive the nozzle 310 to move so that the nozzle 310 is aligned with the grouting port of the grouting template 210. The nozzle 310 is used to pour concrete.

[0047] The monitoring system 100 of the present application is used to photograph the cave wall 900 supported by the support shoe 500 of the TBM. By observing the content photographed by the camera 110 on the display 120, the operator can see the surrounding rock conditions of the cave wall 900 supported by the support shoe 500 of the TBM, thereby eliminating the need for manual observation of the surrounding rock conditions at the cave wall 900, thereby ensuring personal safety.

[0048] If the cave wall 900 to be supported has a cavity and surrounding rock falling off, the template displacement assembly 220 of the template installation system 200 drives the grouting template 210 to move, so as to close the cave wall 900 at this position with the grouting template 210 .

[0049] After the grouting template 210 closes the cave wall 900 at this position, the position of the nozzle 310 is adjusted through the nozzle displacement assembly 320 of the grouting system 300, so that the nozzle 310 is aligned with the grouting port of the grouting template 210, and then concrete is poured into the grouting port of the grouting template 210 through the nozzle 310, thereby achieving the sealing grouting of the cave wall 900 at this position, completing the advanced support, and facilitating the subsequent TBM support shoe 500 to support this place.

[0050] Since the present application uses the monitoring system 100 to observe in advance the cave wall 900 supported by the support shoe 500 of the TBM, there is no need for manual observation there, which improves the observation efficiency, ensures personal safety, and reduces safety hazards; at the same time, the mold sealing and grouting are carried out through the formwork installation system 200 and the grouting system 300, which further improves the efficiency of the mold sealing and grouting compared to manual construction, reduces the high work intensity of the construction personnel, and ensures the personal safety of the workers.

[0051] It should be noted that the TBM gripper shoes 500 are generally provided in two groups, and the present application provides two advance injection molding devices for the TBM gripper shoe parts, and the two advance injection molding devices for the TBM gripper shoe parts correspond one to one to the two groups of TBM gripper shoes 500.

[0052] In another embodiment, referring to Figure 1 , Figure 4 and Figure 5 As shown, the template displacement assembly 220 includes a slider 221, a guide rail 222 and a travel cylinder 223. The guide rail 222 is set on the main beam 400, and the direction of the guide rail 222 is the same as the length direction of the main beam 400. The slider 221 is slidably connected to the guide rail 222. The grouting template 210 is set on the slider 221. The travel cylinder 223 is connected to the slider 221. The travel cylinder 223 is configured to drive the slider 221 to move on the guide rail 222.

[0053] Because the moving direction of the TBM's support shoe 500 is the length direction of the TBM's main beam 400, that is, only the displacement of the grouting template 210 in the length direction of the main beam 400 needs to be changed to ensure that the grouting template 210 covers all the cave walls 900 to be supported by the support shoe 500. When the cave wall 900 to be supported by the support shoe 500 needs to be grouted, the cave wall 900 to be supported by the support shoe 500 at this time is the cave wall 900 to be grouted. In this embodiment, the slider 221 is driven to move on the guide rail 222 by the travel cylinder 223, so that the grouting template 210 is displaced along the length direction of the main beam 400, ensuring that the grouting template 210 can be aligned with the cave wall 900 to be grouted, thereby facilitating the grouting template 210 to close the cave wall 900 to be grouted.

[0054] In certain embodiments, reference Figure 4 and Figure 5 As shown, the template displacement assembly 220 also includes a tightening cylinder 224 and at least one guide column 225. At least one guide sleeve 600 is provided on the grouting template 210. Each guide column 225 is sleeved in each guide sleeve 600 in a one-to-one manner. The tightening cylinder 224 is provided on the slider 221. The output end of the tightening cylinder 224 is connected to the grouting template 210. The tightening cylinder 224 is configured to drive the grouting template 210 to move along the length direction of the guide column 225 so that the grouting template 210 is close to or away from the cave wall 900 to be grouted.

[0055] In this embodiment, the grouting template 210 is driven to move along the length direction of the guide column 225 by the tightening cylinder 224, so that the grouting template 210 can be pressed against the hole wall 900 to be grouted. When the grouting template 210 needs to be repositioned, the grouting template 210 is moved away from the hole wall 900 to be grouted by the tightening cylinder 224, that is, the grouting template 210 is contracted, so that the grouting template 210 is moved to the next position.

[0056] In one embodiment, referring to Figure 4 and Figure 5 As shown, the template displacement assembly 220 also includes a buffer spring assembly 226 , and the tightening cylinder 224 is connected to the grouting template 210 via the buffer spring assembly 226 .

[0057] In this embodiment, the tensioning cylinder 224 is connected to the grouting template 210 through the buffer spring assembly 226, so as to prevent the vibration of the main beam 400 and the tensioning cylinder 224 during the operation of the TBM from causing excessive shaking of the grouting template 210, thereby affecting the sealing and grouting construction, thereby improving the stability and safety of the construction and reducing the impact of vibration on grouting during the excavation process.

[0058] In other possible embodiments, refer to Figure 2 and Figure 6As shown, the nozzle displacement assembly 320 includes a support frame 321 and a manipulator 322 . The support frame 321 is disposed on the main beam 400 , the manipulator 322 is disposed on the support frame 321 , and the nozzle 310 is connected to the output end of the manipulator 322 .

[0059] In this embodiment, the position of the nozzle 310 is adjusted by the manipulator 322 so that the nozzle 310 can be aligned with the grouting port of the grouting template 210 .

[0060] In another possible embodiment, referring to Figure 6 As shown, the nozzle displacement assembly 320 also includes a swivel mechanism 323, and the manipulator 322 is rotatably connected to the support frame 321 through the swivel mechanism 323. Since the manipulator 322 is rotatably connected to the support frame 321, the range of movement of the manipulator 322 is increased, ensuring that the nozzle 310 can be aligned with the grouting port of the grouting template 210.

[0061] In some possible embodiments, reference Figure 1 As shown, a saddle frame 700 and a compensating cylinder 800 are also included. The saddle frame 700 is used to install the TBM support shoe 500. The compensating cylinder 800 is arranged on the main beam 400, and the output end of the compensating cylinder 800 is connected to the saddle frame 700.

[0062] During the excavation process of the TBM, the propulsion cylinder 1000 of the TBM extends, and when the main beam 400 of the TBM moves forward, the shoe 500 on the saddle frame 700 needs to abut against the cave wall 900, that is, the shoe 500 and the saddle frame 70 are stationary relative to the cave wall 900, and the compensation cylinder 800 will extend. The expansion and contraction amount of the travel cylinder 223 can be adjusted by the expansion and contraction amount of the compensation cylinder 800, so as to ensure that the grouting template 210 and the cave wall 900 are relatively stationary, and prevent the grouting template 210 from moving out of the cave wall 900 to be grouted.

[0063] In another embodiment, a hydraulic control system is also included, and the traveling cylinder 223 and the compensation cylinder 800 are respectively connected to the hydraulic control system. The hydraulic control system is configured to control the traveling cylinder 223 and the compensation cylinder 800 to extend and retract synchronously when the compensation cylinder 800 extends and retracts.

[0064] In this embodiment, the hydraulic control system is used to synchronize the extension and retraction of the traveling cylinder 223 and the compensation cylinder 800. When the compensation cylinder 800 is extended, the hydraulic control system controls the synchronous extension of the traveling cylinder 223, thereby ensuring that the grouting template 210 and the cave wall 900 are relatively still, so that the template can be assembled and grouting can be performed synchronously during excavation, and the quality of the spray mix can be guaranteed.

[0065] In other possible embodiments, refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the monitoring system 100 also includes an operation room 130 and a protection platform 140. The operation room 130 is arranged on the main beam 400, the protection platform 140 is arranged on the upper surface of the operation room 130, the camera 110 is arranged on the lower surface of the protection platform 140, and the display 120 is arranged in the operation room 130.

[0066] In this embodiment, the operator in the operating room 130 observes the content captured by the camera 110 on the display 120, so as to observe the cave wall 900 supported by the support shoe 500 of the TBM. The protection platform 140 protects the camera 110 and the operating room 130 to prevent the upper surrounding rock from falling.

[0067] In another possible embodiment, the protection platform 140 abuts against the cave wall 900 to prevent the surrounding rock above the protection platform 140 from falling into the grouting area.

[0068] Reference Figure 1 , Figure 2 and Figure 3 As shown, the second aspect of the embodiment of the present application provides a TBM, including a main beam 400, on which is provided any one of the above-mentioned advance molding devices for the TBM support shoe part.

[0069] The TBM provided in the present application is provided with any of the above-mentioned advance molding devices for the TBM support shoe part on the main beam 400, wherein the advance molding device for the TBM support shoe part includes a monitoring system 100, a template installation system 200 and a grouting system 300; the monitoring system 100 is arranged on the main beam 400 of the TBM, the monitoring system 100 includes a camera 110 and a display 120, the camera 110 is electrically connected to the display 120, the camera 110 is used to photograph the cave wall 900 supported by the support shoe 500 of the TBM, and the display 120 is used to display the content photographed by the camera 110; the template installation system 200 includes a grouting template 210 and a mold The plate displacement component 220, the template displacement component 220 is arranged on the main beam 400, the output end of the template displacement component 220 is connected to the grouting template 210, and the template displacement component 220 is configured to drive the grouting template 210 to move so that the grouting template 210 closes the hole wall 900 to be grouted; the grouting system 300 includes a nozzle 310 and a nozzle displacement component 320, the nozzle displacement component 320 is arranged on the main beam 400, the output end of the nozzle displacement component 320 is connected to the nozzle 310, and the nozzle displacement component 320 is configured to drive the nozzle 310 to move so that the nozzle 310 is aligned with the grouting port of the grouting template 210, and the nozzle 310 is used to pour concrete.

[0070] The advance molding device for the TBM support shoe part of the present application first observes the situation of the cave wall 900 supported by the support shoe 500 of the TBM through the monitoring system 100. If there is a cavity and surrounding rock detachment in the cave wall 900 to be supported, the grouting template 210 is used to close the cave wall 900 at this position through the template installation system 200, and then concrete is poured into the grouting port of the grouting template 210 through the grouting system 300 to achieve the sealing grouting of the cave wall 900 at this position, completing the advance support, and facilitating the subsequent TBM support shoe 500 to support this place. Since the present application observes the cave wall 900 supported by the support shoe 500 of the TBM in advance through the monitoring system 100, there is no need for manual observation here, which improves the observation efficiency and ensures personal safety, and reduces safety hazards; at the same time, the template installation system 200 and the grouting system 300 are used to perform sealing grouting, which further improves the efficiency of sealing grouting compared with manual construction, reduces the high work intensity of construction personnel, and ensures the personal safety of workers.
