[0002] Pipe jacking is a trenchless construction method, which usually involves vertically excavating two wells at the starting point and the receiving point, and then using a pipe jacking machine in the starting well to gradually push the pipe into the receiving well. During construction, it is usually necessary to set circular openings on the side walls of the starting well and the receiving well so that the pipe jacking machine and the pipe can pass through the openings for jacking. Since the openings are set on the side walls of the well, they need to be reinforced to ensure their structural stability.

A supporting body is formed by the support, and the connection between the steel plate mesh and the support is achieved through the intermediate connecting device. The hole opening for pipe jacking construction is closed by the steel plate mesh, thereby ensuring the stability of the lime soil in the hole, and no longer leaving the hole opening for pipe jacking construction in an open state, thereby improving construction efficiency and eliminating safety hazards caused to railway equipment on the ground.

[0004] However, the above technical solution is inconvenient to lift the entire device during use, and requires a lot of manpower to align the device with the hole; moreover, it has a poor anti-leakage effect at the hole, which easily causes the internal mud to flow out and affect the construction; and it cannot reliably support the jacking pipe.
