[0037] In some embodiments, Figure 4 and 5 As shown, second side plates 33 are fixedly provided on both sides of the top column body 31, and a second bottom plate 32 is fixedly provided on the bottom of the top column body 31. The second bottom plate 32 enables the top column body 31 to be stably placed on the top of the slide plate 400, and a second stop edge 24 is fixedly provided on the top of one end of the top column body 31 away from the plug block 37. The inner side of the second stop edge 24 matches with one end of the top column body 31 on which the plug block 37 is provided, and at the same time matches with one end of the top pick assembly 4, so as to realize the positioning between the top column body 31 and the positioning between the top column body 31 and the top pick assembly 4.

[0038] In some embodiments, corresponding positioning components 6 are provided on both sides of the positioning support tube 22 away from the pad assembly 1 and on both sides of both ends of the top column body 31. When the positioning support tube 22 and the top column body 31, and the top column body 31 and the top column body 31 are aligned, the positioning components 6 between the positioning support tube 22 and the top column body 31, and the top column body 31 and the top column body 31 correspond to each other and are triggered, and it is judged that the positioning support tube 22 and the top column body 31, and the top column body 31 and the top column body 31 are aligned. If it is found that a positioning component 6 is not triggered after splicing and during construction, it is judged that the positioning support tube 22 and the top column body 31, and the top column body 31 and the top column body 31 are offset, and correction is required;

[0039] As a specific implementation of the positioning component 6, the positioning component 6 has a positioning support 61, and the interior of the positioning support 61 is provided with a laser sensor emitting end 62 and a laser sensor receiving end 63 facing opposite directions along its axial direction. One end of the positioning support 61 is provided with an emission channel 64 corresponding to the laser sensor emitting end 62 along its axial direction, and the other end of the positioning support 61 is provided with an injection channel 65 corresponding to the laser sensor receiving end 63 along its axial direction; when the positioning support tube 22 is aligned with the top column body 31, and the top column body 31 is aligned with the top column body 31, the two positioning components 6 correspond to each other, and the laser sensor emitting end 62 in one positioning component 6 emits a laser beam outward along the emission channel 64, and the laser beam is received by the other positioning component 6. The injection channel 65 enters into the laser sensor receiving end 63 and triggers the laser sensor receiving end 63. Therefore, by detecting that the laser sensor receiving end 63 is triggered, it can be determined that the positioning support tube 22 and the top column body 31, as well as the top column bodies 31 and the top column bodies 31 are aligned; when the positioning support tube 22 and the top column body 31, as well as the top column bodies 31 and the top column bodies 31 are offset, the laser sensor emitting end 62 emits a laser beam outward along the injection channel 64 and cannot enter into the injection channel 65 to trigger the laser sensor receiving end 63. Therefore, if it is detected that the laser sensor receiving end 63 is not triggered, it can be determined that the positioning support tube 22 and the top column body 31, as well as the top column bodies 31 and the top column bodies 31 are offset, and timely correction is required.

[0040] In some embodiments, Figure 7 As shown, the pad assembly 1 comprises an outer pad 11 and an inner pad 12, the outer pad 11 being fixedly arranged on one side of the rear wall 200; the outer pad 11 is hinged to one end of the inner pad 12, and an inclination compensation mechanism 14 is arranged between the other ends of the outer pad 11 and the inner pad 12. If there is a large angle error on the side of the rear wall 200 that abuts against the pad assembly 1, direct jacking construction will affect the construction accuracy. In order to compensate for the angle error, the angle between the inner pad 12 and the outer pad 11 can be adjusted by the inclination compensation mechanism 14 to compensate for the angle error and ensure the construction accuracy.

[0041] In some embodiments, Figure 8As shown, the inclination compensation mechanism 14 comprises a rotating support seat 141 rotatably arranged at one end of the outer pad 11 and a rotating adjustment seat 142 rotatably arranged at one end of the inner pad 12, an adjusting bolt 143 rotatably arranged on the rotating support seat 141 and threadedly connected to the rotating adjustment seat 142; two adjusting guide rods 144 parallel to the adjusting bolts 143 are symmetrically arranged on one side of the rotating support seat 141 close to the rotating adjustment seat 142, the rotating adjustment seat 142 is slidably connected to the adjusting guide rod 144, and a limit plate 145 is fixedly arranged at the end of the adjusting guide rod 144 When adjusting, the adjusting bolt 143 is rotated, and the threaded structure between the adjusting bolt 143 and the rotating adjusting seat 142 cooperates, so that the rotating adjusting seat 142 can be driven to approach or move away from the rotating support seat 141, thereby adjusting the angle between the outer pad 11 and the inner pad 12; after the angle between the outer pad 11 and the inner pad 12 is adjusted, there will be a gap between the outer pad 11 and the inner pad 12, and soil can be filled into the gap to form a support between the outer pad 11 and the inner pad 12 to prevent the inner pad 12 from deforming during jacking.

[0042] In some embodiments, a locking nut 146 is assembled on the adjusting bolt 143 on the side of the rotating adjustment seat 142 facing away from the rotating support seat 141, and the locking nut 146 is abutted against one side of the rotating adjustment seat 142. After the angle between the outer pad 11 and the inner pad 12 is adjusted, the locking nut 146 is tightened to abut against one side of the rotating adjustment seat 142, so that the adjusting bolt 143 can be locked with the rotating adjustment seat 142, thereby preventing the adjusting bolt 143 from loosening during construction and affecting the accuracy.

[0043] In some embodiments, Fig. 9 As shown, the top pick assembly 4 has a top pick support 41, a hydraulic cylinder 42 is arranged inside the top pick support 41, and a push plate 43 is arranged at the end of the piston rod of the hydraulic cylinder 42; a positioning slot 52 matching the push plate 43 is fixedly arranged on the push plate assembly 5, and the push plate 43 is inserted into the positioning slot 52. The push plate assembly 5 is connected together by setting the positioning slot 52 matching the top pick assembly 4, thereby improving the stability of the top pick assembly 4. At the same time, the push plate assembly 5 can increase the contact area between the hydraulic cylinder 42 and the end of the culvert, disperse the force, and avoid damage to the culvert.

[0044] In some embodiments, Figures 9 to 11 As shown, locking mechanisms 53 are provided on both sides of the positioning slot 52 for locking or releasing it with the push plate 53;

[0045] The two sides of the push plate 53 are symmetrically provided with locking grooves 44, and the two sides of the positioning slot 52 are provided with clearance holes 521 corresponding to the locking grooves 44;

[0046] The locking mechanism 53 includes a locking block 531 slidably arranged inside the yield hole 521, and the end of the locking block 531 matches the shape of the locking groove 44. A locking support 532 corresponding to the locking block 531 is fixedly arranged on the push plate body 51, and a locking bolt 533 threadedly connected to the locking support 532 is rotatably arranged on one side of the locking block 531 close to the locking support 532; rotating the locking bolt 533 can drive the locking block 531 to be inserted into the locking groove 44 to lock the push plate 53 and the positioning slot 52, or pull the locking block 531 out of the positioning slot 52 to release the push plate 53 and the positioning slot 52.

[0047] In some embodiments, a stopping nut 534 is assembled on the locking bolt 533 between the locking support 532 and the locking block 531, and the stopping nut 534 is abutted against one side of the locking support 532. When the stopping nut 534 is locked between the push plate 53 and the positioning slot 52, it abuts against one side of the locking support 532 to prevent the locking bolt 533 from loosening.
