Description

TECHNICAL FIELD

[0002] Pipe jacking construction is a trenchless construction method, which is a pipe laying construction technology without or with less excavation. In the pipe jacking construction process, a pipe jacking machine is needed. The pipe jacking construction is to overcome the friction between the pipe and the surrounding soil by using the jacking force generated by the jacking equipment in the working pit, and then to jack the pipe into the soil according to the designed slope, and to remove the earthwork. After one section of pipe is jacked into the soil, the next section of pipe is jacked in.

[0003] However, the pipe jacking machine cannot achieve better balance and stability during use, and the balance and stability of the pipe jacking machine during work are poor. Moreover, the pipe jacking machine generates large vibration and noise during use, which leads to a poor working environment for the workers and cannot better ensure the use of the pipe jacking machine.

[0004] A patent with the publication number CN110630280A discloses a balancing device for slurry balance pipe jacking machine. The technical solution points of the patent are as follows: a box body is provided, a pipe jacking machine body penetrates through the inside of the box body, sliding rails are fixedly connected to the inner walls of the box body, sliding blocks are slidingly connected to the outer surfaces of the sliding rails, a horizontal plate is fixedly connected to the opposite side of the two sliding blocks, a stabilizing piece is fixedly connected to the bottom of the horizontal plate, gear racks are fixedly connected to the two sides of the top of the horizontal plate, and a fixed plate is fixedly connected to the front of the pipe jacking machine body. The balancing device can achieve better balance and stability during the working process of the pipe jacking machine, greatly improves the balance and stability of the pipe jacking machine during work, better ensures the use of the pipe jacking machine, has high practicability, can reduce vibration and noise of the pipe jacking machine, and optimizes the working environment of the workers using the pipe jacking machine. However, the above-mentioned technology often has the following defects: the above-mentioned slurry balance pipe jacking machine cannot adjust the pillow block horizontally during use. If the pillow block is inclined, the non-horizontal support of the pillow block will cause the pipe jacking machine and the pipe section to bear additional eccentric force instead of uniform axial jacking force, which will cause physical damage to the mechanical parts and the pipe section in the long run.
