A kind of pipe jacking construction technology

Abstract

The present application relates to the technical field of pipe jacking construction. Aiming at the problem that the process of placing pipes on the track is relatively complicated in the traditional pipe jacking construction process, a pipe jacking construction process is proposed. There are two sets of fixed plates in the starting shaft. The two sets of fixed plates are arranged symmetrically about the vertical plane where the track is located. The top of the fixed plates is hinged with a receiving plate. When the pipe is placed between the two sets of receiving plates, the two sets of receiving plates are driven to swing by the driving component. When the distance between the two sets of receiving plates is greater than the outer diameter of the two sets of receiving plates, the pipeline can fall accurately. on track.

Description

technical field [0001] The present application relates to the technical field of pipe jacking construction, in particular to a pipe jacking construction process. Background technique [0002] Pipe jacking construction can bury relevant pipelines without extensive excavation on the ground, and is usually used in pipeline burying projects where the terrain is complex and ground excavation cannot be carried out. [0003] In the related art, before the pipe jacking construction, the starting well and the arrival well need to be excavated on the ground, then the track is laid in the starting well and the jacking equipment is installed, and the pipe jacking machine such as a crane is used to lift it into the starting well and place it in the track. , and then hoist the pipeline to be laid on the track, start the pipe jacking machine, the jacking equipment drives the pipeline and the pipe jacking machine to move horizontally, and the jacking equipment is jacked to the limit positio...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: during the pipe jacking construction process, the pipe is usually hoisted into the track by means of a crane and a wire rope, and the pipe is prone to deviation during the hoisting process, resulting in the need for construction during the hoisting process. Personnel assist in adjusting the position of the pipeline at the bottom of the well, so that the pipeline can face the track and fall onto the track smoothly, reducing the situation that the pipeline falls outside the track. The overall operation is more complicated, and there is a certain degree of danger in this process
