Description

Technical Field

[0001] The utility model mainly relates to the technical field of pipe jacking, in particular to a pipeline positioning device used for pipe jacking construction. Background Art

[0002] The pipe jacking method is to overcome the friction between the pipe and the surrounding soil in the working pit with the help of the jacking force generated by the jacking equipment, and push the pipe into the soil according to the designed slope. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in. The pipe jacking method can reduce the damage to road traffic and can be used for the laying of water supply pipelines. When the pipe jacking is carried out, the soil covering thickness of the pipe jacking is generally not less than 3m or not less than 1.5 times the outer diameter of the pipe. At this time, the requirements for pipe jacking construction are more stringent.

[0003] At present, during the construction of pipe jacking, after one end of the first pipe jacking is pushed into the soil, a second pipe jacking needs to be welded to the other end of the first pipe jacking. Since the second pipe jacking is in a suspended state, it is easy to shake, so there will be position deviation when the two pipe jacking are welded, which will cause the overall axis of the pipeline to shift and the construction route to deviate. When the overall pipeline shifts, it is not easy to correct the position of the main pipeline, which greatly increases the difficulty of construction. When the pipeline shifts, additional correction work is required. This process increases the additional expenditure of manpower and material resources and affects the progress of the project.
