[0022] The present invention provides a tunneling type pipeline burying machine for use in soft geological conditions and a method of using the same, which will be described in detail below with reference to specific embodiments.

[0023] like Figure 1As shown, an embodiment of the present invention provides a tunneling type pipeline burying machine for soft geological conditions, including a delivery box 1, a tunneling box 2 and an auger 3; the delivery box 1 is provided with an inlet 11, an outlet 12 and a delivery channel 13 connected between the inlet 11 and the outlet 12, the inlet 11 is located at the top of the delivery box 1, the outlet 12 is located at the bottom of the delivery box 1, the inlet 11, the outlet 12 and the delivery channel 13 are used for the pipeline 4 to pass through; the tunneling box 2 is provided at the front end of the delivery box 1 for moving forward; the auger 3 is provided in the tunneling box 2 for digging the soft soil 5 to the surface.

[0024] The soft soil may be sand, silt, or other soil, and the pipeline 4 may be a flexible, bendable cable such as an electric cable or water pipe. The tunneling box 2 may be moved forward by human drag or by a towing machine. The delivery box 1 and tunneling box 2 may be an integrated structure. Specifically, the auger 3 may include a drive mechanism 31 and an auger rod 32. The drive mechanism 31 is operatively connected to the auger rod 32 to rotate the auger rod 32, thereby excavating the soft soil 5 to the surface. The drive mechanism 31 may be a device such as an electric motor or an engine capable of rotating the auger rod.

[0025] In this embodiment, the delivery box 1 is provided with an inlet 11, an outlet 12 and a delivery channel 13 for the pipeline 4 to pass through, so as to play the role of delivering the pipeline 4 into the underground. The excavation box 2 is arranged at the front end of the delivery box 1, and can drive the delivery box 1 and the auger 3 forward when moving forward underground. The auger 3 is arranged in the excavation box 2, and can continuously dig the soft soil 5 to the surface as the excavation box 2 moves forward. When it is necessary to bury the pipeline 4, the pipeline burying machine can be inserted into the underground, and the excavation box 2 moves forward and drives the delivery box 1 and the auger 3 to move forward. The auger drill 3 moves forward, and the soft soil 5 is continuously excavated to the surface when the auger drill 3 moves forward. When the drop box 1 moves forward, the pipeline 4 continuously enters the underground area behind the excavated soil through the drop box 1. After moving forward, the soft soil 5 collapses by itself to bury the pipeline 4, thereby completing the burial construction of the pipeline 4, realizing trenchless construction, which can reduce the excavation damage to the surface and thus reduce the disturbance caused to the surface. At the same time, it realizes burying the line while moving forward, which can be completed quickly in one go without frequent support, thereby improving construction efficiency and reducing construction costs.

[0026] Alternatively, as Figure 1As shown, the delivery box 1 includes a first box body 14 and a second box body 15, the first box body 14 is arranged vertically, the second box body 15 is connected to the lower end of the first box body 14 and is tilted backward in a downward direction, the lower end of the inner cavity of the first box body 14 is connected to the upper end of the inner cavity of the second box body 15 to form the delivery channel 13, the top of the first box body 14 is open to form the inlet 11, and the bottom of the second box body 15 is open to form the outlet 12.

[0027] Specifically, the first box body 14 and the second box body 15 may be an integrated structure to reduce the gap at the connection between the first box body 14 and the second box body 15 to prevent the soft soil 5 from entering.

[0028] In this optional embodiment, the first box body 14 is arranged vertically, which makes it easier for the pipeline 4 to be dropped into the drop box 1; the second box body 15 is connected to the lower end of the first box body 14 and is tilted backward in a downward direction, so that the entire drop box 1 has a downward and backward bending structure, that is, the delivery channel 13 is downward and backward bending, and the entire pipeline burying machine moves forward, so the downward and backward bending delivery channel 13 can make the pipeline 4 easier to extend from the drop box 1, thereby further improving construction efficiency.

[0029] Alternatively, as Figure 1 As shown, the front side wall of the first box body 14 includes two inclined walls 141 , the front ends of the two inclined walls 141 are connected, and the rear ends of the two inclined walls 141 are spaced apart so that the two inclined walls 141 are arranged at an angle.

[0030] Specifically, the angle between the two inclined walls 141 is less than 180°, and may be, for example, an acute angle, a right angle, or an obtuse angle.

[0031] In this optional embodiment, the front ends of the two inclined walls 141 are connected, and the rear ends of the two inclined walls 141 are spaced apart so that the two inclined walls 141 are set at an angle. In this way, the front side wall forms a sharp angle facing forward, which is beneficial to reducing the resistance encountered by the delivery box 1 when moving forward.

[0032] Alternatively, as Figure 2 and Figure 3 As shown, a first inclination angle is formed between the plane where the peripheral edge of the outlet 12 is located and the horizontal plane, and the opening of the first inclination angle is arranged upward and backward.

[0033] In this optional embodiment, the opening of the first inclination angle formed between the plane where the periphery of the outlet 12 is located and the horizontal plane is set upward and backward, which means that the entire outlet 12 is in a downward and backward state, which can prevent a large amount of soft soil 5 from entering the delivery box 1 and hindering the extension of the pipeline 4.

[0034] Alternatively, as Figure 2 and Figure 3 As shown, the tunneling type pipeline burying machine for soft geological conditions also includes a cover plate 6, which is covered on the outlet 12. The lower end of the cover plate 6 is rotatably connected to the bottom of the delivery box 1, and the upper end of the cover plate 6 is provided with a protrusion 61 protruding from the peripheral side wall of the delivery box 1 along the radial direction of the outlet 12. When the delivery box 1 moves forward driven by the tunneling box 2, the protrusion 61 is subjected to the resistance of the soft soil 5 to drive the cover plate 6 to rotate around the axis of its rotational connection with the delivery box 1 to open the outlet 12.

[0035] It should be noted that the specific implementation method for the rotational connection between the lower end of the cover plate 6 and the bottom of the delivery box 1 is not specifically limited here. In addition, the shape of the cover plate 6 can be adapted to the shape of the outlet 12. For example, if the outlet 12 is square, the cover plate 6 can also be square.

[0036] In this optional embodiment, since the outlet 12 is covered with a rotatable cover plate 6 and the cover plate 6 is provided with a protrusion 61, during the process of the pipeline burying machine being gradually inserted into the ground, the cover plate 6 can be blocked by the soft soil 5 to be tightly attached to the bottom of the delivery box 1, thereby closing the outlet 12 and preventing the soft soil 5 from entering the delivery box 1. When the delivery box 1 moves forward driven by the excavation box 2, the protrusion 61 can be affected by the resistance of the soft soil 5 to drive the cover plate 6 to rotate around the axis of its rotational connection with the delivery box 1 to open the outlet 12, so that the cover plate 6 automatically opens when moving forward to facilitate the extension of the pipeline 4.

[0037] Furthermore, a deformable sheet is provided at the lower edge of the cover plate 6, and the deformable sheet is connected to the bottom of the delivery box 1. The deformable sheet is provided with a fold extending in the direction of the axis of the rotational connection between the cover plate 6 and the delivery box 1. With such a configuration, the deformable sheet can be deformed at the fold to allow the cover plate 6 to rotate relative to the delivery box 1, thereby realizing a rotational connection between the lower end of the cover plate 6 and the bottom of the delivery box 1. In this way, a rotational connection can be realized, and compared with a pin connection to realize a rotational connection, it can prevent particles of soft soil 5 from entering the connection and causing jamming.

[0038] Alternatively, as Figure 3 and Figure 4 As shown, the excavation box 2 includes two vertically arranged box plates 21 and horizontally arranged ribs 22. The two box plates 21 are arranged opposite to each other in the left and right directions. The ribs 22 are located between the two box plates 21 and are respectively connected to the two box plates 21. An installation opening 221 is opened on the ribs 22, and the spiral drilling machine 3 is inserted into the installation opening 221.

[0039] Specifically, the two box panels 21 can be connected to the delivery box 1. Specifically, the auger rod 32 of the auger drill 3 is inserted into the mounting opening 221. The excavation box 2 also includes a back panel 23, which is connected to the rear ends of the two box panels 21. The back panel 23 can be used to mount the drive mechanism 31 of the auger drill 3. Furthermore, the lower end of the auger rod 32 of the auger drill 3 can be located between the two box panels 21, and the upper end can be extended from between the two box panels 21 to be exposed outside the excavation box 2, facilitating the discharge of the excavated soft soil 5.

[0040] In this optional embodiment, two box plates 21 and rib plates 22 form the excavation box 2, which can form a trough-shaped structure in which each plate surface is parallel to the front-to-back direction. The front area directly facing the soft soil 5 in front is small, which can effectively reduce the resistance during forward movement; the rib plates 22 connected between the two box plates 21 can play a role in structural reinforcement, thereby increasing the lateral compression strength of the entire excavation box 2; the two box plates 21 are arranged vertically and the rib plates 22 are arranged horizontally, so that the space enclosed by the two box plates 21 and the rib plates 22 is just through-through, which makes it more convenient for the soft soil 5 to pass through, thereby guiding it to the spiral drilling machine 3 to achieve rapid excavation and discharge; the horizontally arranged rib plates 22 can realize the forward and backward flow of the soft soil 5, which is consistent with the moving direction of the excavation box 2. The flow of the soft soil 5 will not interfere too much with the forward movement of the excavation box 2, thereby ensuring the horizontality of the forward direction of the excavation box 2, thereby improving the construction quality of the buried pipeline 4.

[0041] Furthermore, the tunneling box 2 can also include a guide plate, which is arranged horizontally, and the rear end of the guide plate is connected to the front end of the two box plates 21. The guide plate is used to be placed on the ground. With this arrangement, the guide plate can move along the ground when the tunneling box 2 moves forward. This can not only guide the forward movement of the tunneling box 2, but also ensure the posture of the entire tunneling box 2, and prevent the tunneling box 2 from tilting up and down and affecting the horizontality of the forward direction.

[0042] Alternatively, as Figure 4 As shown, a plurality of ribs 22 are provided between the two box plates 21 , and the plurality of ribs 22 are sequentially spaced apart in the up-down direction, and the auger 3 passes through the installation openings 221 of the plurality of ribs 22 .

[0043] Specifically, the auger rod 32 of the auger drill 3 passes through the installation openings 221 of the plurality of ribs 22 , and the extension direction of the auger rod 32 is consistent with the arrangement direction of the plurality of ribs 22 , so as to correspondingly excavate the soft soil 5 at different ribs 22 .

[0044] In this optional embodiment, multiple ribs 22 arranged in sequence in the upper and lower directions can distribute the soft soil 5 more evenly, effectively preventing the tunneling box 2 from swinging when the soft soil 5 passes through, thereby further improving the horizontality of the tunneling box 2 in the forward direction; and, multiple ribs 22 can further improve the lateral pressure resistance of the entire tunneling box 2; in addition, the auger 3 passes through the mounting openings 221 of multiple ribs 22, so that the auger 3 can be limited by multiple mounting openings 221 at the same time, which can improve the stability of the installation of the auger 3.

[0045] Alternatively, as Figure 3 and Figure 4 As shown, the box plate 21 extends gradually and tiltedly forward from the lower end to the upper end, and the arrangement direction of the plurality of ribs 22 is the same as the extension direction of the box plate 21.

[0046] Specifically, the arrangement direction of the plurality of ribs 22 can be the direction of a line connecting the center points of the plurality of ribs 22. When the box plate 21 extends gradually and tilted forward from the lower end to the upper end, the direction of the line connecting the center points of the plurality of ribs 22 can also be tilted upward and forward. Specifically, the extension direction of the auger rod 32 can be the same as the arrangement direction of the plurality of ribs 22.

[0047] In this optional embodiment, the box plate 21 gradually extends forward from the lower end to the upper end, so that the entire excavation box 2 is tilted forward to further reduce the resistance to forward movement; the arrangement direction of the multiple ribs 22 is the same as the extension direction of the box plate 21, so that the positions of the multiple ribs 22 are more adapted to the shape of the box plate 21, which can further improve the lateral pressure resistance of the entire excavation box 2.

[0048] Alternatively, as Figure 4 As shown, a mounting hole 211 is provided at the upper end of the box plate 21 , and the mounting hole 211 is used to install an operating handle or connect to the output end of the towing machine.

[0049] Specifically, the upper end of the box plate 21 can be provided with multiple mounting holes 211. For example, there are two mounting holes 211. When one mounting hole 211 is deformed and fails, the remaining mounting holes 211 can be used as backup to improve the reliability of the excavation box 2.

[0050] In this optional embodiment, the mounting hole 211 can be used to install an operating handle or be connected to an output end of a towing machine, so that the entire boring box 2 can be towed and moved by an external force.

[0051] Furthermore, the mounting holes 211 on the two box plates 21 can be arranged relative to each other in the left-right direction, so that the operating handles can be passed through at the same time or the output ends of the dragging machinery can be connected at the same time, which can improve the reliability of the connection.

[0052] like Figure 5As shown, an embodiment of the present invention provides a method for using the above-mentioned tunneling pipeline burying machine for soft geological conditions, including: Inserting the lower part of the tunneling pipeline burying machine into the ground; The excavation box 2 moves forward to drive the auger 3 and the delivery box 1 to move forward. When the auger 3 moves forward, the soft soil 5 in front is continuously excavated to the surface. When the delivery box 1 moves forward, the pipeline 4 is continuously delivered to the delivery channel 13 through the inlet 11, so that the pipeline 4 leaves the delivery channel 13 through the outlet 12 and enters the soft soil 5.

[0053] Specifically, when the lower portion of the tunneling pipeline burying machine is inserted into the ground, the upper end of the auger rod 32 of the auger drill 3 is exposed above the ground surface. Furthermore, the pipeline 4 can be a cable or a water pipe. If the pipeline 4 is a cable, the lower end of the cable needs to be connected to electrical equipment. Therefore, when the cable is dropped into the drop box 1, the cable and the electrical equipment can be dropped into the drop box 1 together. If the pipeline 4 is a water pipe, the lower end of the water pipe does not need to be connected to ground equipment. Therefore, when dropping the water pipe into the drop box 1, only the water pipe can be dropped into the drop box 1.

[0054] In this embodiment, the lower part of the tunneling pipeline burying machine is first inserted into the ground, and then the tunneling box 2 moves forward to drive the auger 3 and the delivery box 1 to move forward. When the auger 3 moves forward, the soft soil 5 in front is continuously excavated to the surface. While the delivery box 1 moves forward, the pipeline 4 is continuously delivered to the delivery channel 13 through the inlet 11, so that the pipeline 4 leaves the delivery channel 13 through the outlet 12 and enters the soft soil 5, and finally the pipeline 4 burying construction is completed. There is no need to excavate a trench in the soft soil 5, thereby reducing the ecological disturbance to the surface. At the same time, the line burying can be completed synchronously when the pipeline burying machine moves forward, without the need for frequent support construction, thereby improving construction efficiency and reducing construction costs.

[0055] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
