[0022] When it is necessary to push and guide the jacking pipe in the loess layer, this device can be used to make the base 1 contact with the ground, and then place the jacking machine on the first roller 6 on the first support frame 5, and then start the first hydraulic rod 3 on the fixed frame 2, and drive the equalizing block 4 to move through the first hydraulic rod 3, thereby pushing the jacking machine to move, so that the first roller 6 rotates, and the jacking machine moves to the second roller 14, and then the first hydraulic rod 3 is reversed to drive the equalizing block 4 to move in the opposite direction and reset, and then the jacking pipe is placed on the first roller 6, and then the motor 8 and the first hydraulic rod are started. A hydraulic rod 3 drives the gear to rotate through the motor 8, and the gear and the gear ring engage with each other to rotate, so that the cleaning brush 10 rotates, and the equalizing block 4 moves through the first hydraulic rod 3, thereby pushing the jacking pipe to move, so that the first roller 6 rotates, so that the jacking pipe contacts the cleaning brush 10.

During the operation, the second hydraulic rod 12 can be started, and the third support frame 13 can be driven by the second hydraulic rod 12 to move along the slide rail 11, thereby driving the second roller 14 and the jacking pipe to move. After moving to a suitable height, the second hydraulic rod 12 is closed, and then the equalizing block 4 is moved to continue to push the jacking pipe to move and contact with the guide wheel 16 for centering propulsion, so that the position of the jacking pipe can be corrected for centering and guiding propulsion, reducing errors, reducing construction costs, facilitating the propulsion of the jacking pipe, and improving the convenience of use. After the propulsion is completed, the first hydraulic rod 3 is closed, and then the device can be removed.
