The inclined plate 29 is inclined. The high-pressure jet grouting rig 32 is slidably installed on the lifting plate 28, and the high-pressure jet grouting rig 32 can only slide along the extending direction of the lifting plate 28.

[0067] In order to push the inclined plate 29 to rotate circumferentially around the axis of its own hinge shaft 21, a pushing member is further provided. The pushing member includes: a pushing oil cylinder 27.

[0068] The housing of the pushing oil cylinder 27 is hinged to the hinge block 20, and the piston rod of the pushing oil cylinder 27 is hinged to the inclined plate 29.

[0069] In order to drive the rotating block 23 to rotate around its own axis, a rotating structure is further provided. The rotating structure includes: a gear ring 24, a rotating motor 25, and a rotating gear 26.

[0070] An empty groove 35 is provided on the groove wall of the rotating groove 34. The gear ring 24 is rotatably connected in the empty groove 35. The gear ring 24 is fixedly sleeved on the rotating block 23. The rotating motor 25 is fixedly connected in the adjusting plate 22. The rotating gear 26 is fixedly connected to the output rotating shaft of the rotating motor 25. The rotating gear 26 meshes with the gear ring 24.

[0071] Among them, the specific structure of the high-pressure rotary jet grouting rig 32 can refer to the high-pressure rotary jet grouting rig disclosed in the publication number: CN111550182A. The high-pressure rotary jet grouting rig includes a vehicle body, a traveling mechanism, a working platform, a drill rod device, a rotary mast mechanism and a power head.

[0072] Embodiment 1: In order to drive the working platform 17 to move horizontally, a horizontal moving member is further provided. The horizontal moving member includes: a horizontal rack 13, a horizontal slider 14, a horizontal motor 15, and a horizontal gear 16. (As Figure 5 、 Figure 6 shown)

[0073] The horizontal rack 13 is fixedly connected to the top wall of the connecting frame 12. The horizontal slider 14 is slidably connected to the top wall of the connecting frame 12. The horizontal motor 15 is fixedly connected in the horizontal slider 14. The horizontal gear 16 is fixedly connected to the output rotating shaft of the horizontal motor 15. The horizontal gear 16 meshes with the horizontal rack 13. The top wall of the horizontal slider 14 is fixedly connected to the working platform 17.

[0074] Embodiment 2: As another horizontal moving member, the horizontal moving member includes: a horizontal oil cylinder 38; the housing of the horizontal oil cylinder 38 is hinged to the moving mechanism 11, and the piston rod of the horizontal oil cylinder 38 is hinged to the bottom wall of the working platform 17. (As Figure 1 、 Figure 2 shown)

[0075] Working or installation process:

[0076] Drive the moving mechanism 11 to move on the ground rail 36 in the tunnel. The moving mechanism 11 drives the working platform 17 to move synchronously and makes the high-pressure rotary jet grouting rig 32 move to the longitudinal position in the tunnel where the cement-soil pile needs to be driven;

[0077] Working process of Embodiment 1: The horizontal motor 15 is started. The output rotating shaft of the horizontal motor 15 drives the horizontal gear 16 to rotate. The horizontal gear 16 drives the horizontal slider 14 to move by meshing with the horizontal rack 13. The horizontal slider 14 drives the working platform 17 to move horizontally in the tunnel, so as to drive the high-pressure rotary jet grouting rig 32 to move to the horizontal position in the tunnel where the cement-soil pile needs to be driven through the working platform 17; at this time, the horizontal motor 15 turns on the self-locking mode so that the horizontal slider 14 stays and is fixed at this position.

[0078] Working process of the second embodiment: The horizontal oil cylinder 38 is started, and the piston rod of the horizontal oil cylinder 38 extends and pushes the side wall of the moving mechanism 11, causing the horizontal slider 14 to move along the extension direction of the connecting frame 12 until the high-pressure jet grouting rig 32 moves to the corresponding position. Among them, the operations of the first embodiment and the second embodiment can both drive the horizontal slider 14 to move horizontally along the extension direction of the connecting frame 12.

[0079] If it is necessary to drive the cement-soil piles vertically downward into the tunnel floor, after the position is determined, the pushing oil cylinder 27 is started, and the piston rod of the pushing oil cylinder 27 extends and pushes the inclined plate 29, causing the inclined plate 29 to rotate around its own axis of the hinge shaft 21. The inclined plate 29 rotates from the inclined state to the state perpendicular to the ground, and the high-pressure jet grouting rig 32 is vertical downward. The high-pressure jet grouting rig 32 is started to drive the cement-soil piles into the tunnel.

[0080] If it is necessary to drive the cement-soil piles obliquely downward into the tunnel floor, the inclined plate 29 is inclined to the tunnel floor, and the head of the high-pressure jet grouting rig 32 is inclined to the tunnel floor to drive the cement-soil piles obliquely downward into the tunnel floor.

[0081] If the position where the cement-soil piles need to be driven is on the tunnel side wall, it is necessary to adjust the high-pressure jet grouting rig 32 so that the head position of the high-pressure jet grouting rig 32 faces the inner side wall of the tunnel. The rotation motor 25 is started, and the output rotating shaft of the rotation motor 25 drives the rotation gear 26 to rotate. The rotation gear 26 drives the gear ring 24 to rotate by meshing with the gear ring 24. The gear ring 24 drives the rotation block 23 to rotate. The rotation block 23 drives the lifting plate 28 to rotate synchronously. The lifting plate 28 drives the high-pressure jet grouting rig 32 to rotate around its own axis of the rotation block 23 and makes the head position of the high-pressure jet grouting rig 32 face the position where the cement-soil piles need to be driven; by rotating the rotation block 23, the drill head of the high-pressure jet grouting rig 32 can drive the cement-soil piles at multiple angles; at this time, the rotation motor 25 turns on the self-locking mode, and the rotation angle of the inclined high-pressure jet grouting rig 32 is fixed and will not rotate and shift.

[0082] If the depth of the cement-soil piles to be driven is relatively deep and the elongation length of the drill head of the high-pressure jet grouting rig 32 is insufficient, at this time, the lifting oil cylinder 30 is started, and the piston rod of the lifting oil cylinder 30 extends and drives the high-pressure jet grouting rig 32 to move. The high-pressure jet grouting rig 32 moves along the extension direction of the lifting plate 28, thereby increasing the length of the drill head of the high-pressure jet grouting rig 32.

[0083] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept.
