[0027] A driving motor 10 is installed in the pushing assembly 6, a screw rod 11 is installed at the output end of the driving motor 10, a chassis 13 is installed on the screw rod 11, and the screw rod 11 penetrates the chassis 13, a guide rod 12 is correspondingly installed on the right side of the driving motor 10, and the guide rod 12 penetrates the chassis 13, a support rod 8 is fixedly installed at the bottom of the chassis 13, and the other end of the support rod 8 extends out of the pushing assembly 6, and the other end of the support rod 8 is fixedly connected to a pressure plate 9, a plurality of groups of hooks 7 are installed on the outer wall of the pushing assembly 6, and a plurality of groups of buckles 14 corresponding to the hooks 7 are installed on the outer wall of the tube body 1;

[0028] First, insert the pipe body 1 into the ground, inject cement slurry into the pipe body 1, align the pushing assembly 6 with the pipe body 1 and install it, clamp the buckle 14 on the hook 7, and lock the pushing assembly 6. Then, drive the motor 10 to drive the screw rod 11 to rotate, and the rotation of the screw rod 11 drives the chassis 13 to move downward along the guide rod 12, and the chassis 13 is connected to the pressure plate 9 through the support rod 8, so that the chassis 13 moves downward, pushing the pressure plate 9 to move downward to push the cement slurry in the pipe body 1, and vice versa, the drive motor 10 drives the screw rod 11 in the reverse direction to rotate, and the screw rod 11 drives the chassis 13 to move upward, and the mud pushing work is completed in a cycle.

[0029] See also Figure 1 , Figure 2 and Figure 6 A protective shell 15 is installed at one end of the tube body 1, a limit shell 16 is installed in the protective shell 15, a spring 17 is installed in the limit shell 16, and one end of the spring 17 is connected to a block 18.

[0030] Two sets of sleeves 3 are correspondingly installed on the outer wall of the tube body 1, and two sets of fixing pins 4 are correspondingly installed on the outer wall of the bottom of the tube body 1. The bottom of the tube body 1 is provided with a groove 5 corresponding to the block 18, and the inner diameter of the groove 5 is adapted to the outer diameter of the block 18;

[0031] When the length of the pipe body 1 needs to be increased, the spliced ​​pipe body 1 is aligned with the end of the pipe body 1 driven into the ground and pushed downward to insert the fixing pin 4 into the sleeve 3. The outer wall of the pipe body 1 will push the block 18 into the protective shell 15. When the groove 5 drops to the same level as the block 18, the block 18 rebounds into the groove 5 using the elastic principle of the spring 17 to lock the pipe body 1. The limit shell 16 provides a guide for the rebound compression of the spring 17. The sleeve 3 and the fixing pin 4 are conducive to the alignment and splicing of the pipe body 1 when splicing.

[0034] Working principle: insert the pipe body 1 into the ground, inject cement slurry into the pipe body 1, align the pushing assembly 6 with the pipe body 1, clamp the buckle 14 on the hook 7, lock the pushing assembly 6, and then drive the motor 10 to drive the screw rod 11 to rotate. The rotation of the screw rod 11 drives the chassis 13 to move downward along the guide rod 12, and the chassis 13 is connected to the pressure plate 9 through the support rod 8. In this way, the chassis 13 moves downward, pushing the pressure plate 9 to move downward to push the cement slurry in the pipe body 1. Conversely, the driving motor 10 drives the screw rod 11 in the reverse direction to rotate, and the screw rod 11 drives the chassis 1 3 moves upward, and after the mud pushing is completed in sequence, the buckle 14 is pressed to remove the pushing assembly 6 to harden the mud. Finally, when the length of the pipe body 1 needs to be increased, the spliced ​​pipe body 1 is aligned with the end of the pipe body 1 driven into the ground and pushed downward to insert the fixing pin 4 into the sleeve 3. The outer wall of the pipe body 1 will push the block 18 into the protective shell 15. When the groove 5 drops to the same level as the block 18, the block 18 rebounds into the groove 5 using the elastic principle of the spring 17, locking the pipe body 1 to complete the splicing work. The splicing and installation can be carried out in sequence according to the length of the pipe body 1 required by the foundation.
