Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for pipe jacking construction, in particular to a pipe axial correction device for pipe jacking construction. Background Art

[0002] Pipe jacking construction is a trenchless construction method and a pipeline burial construction technology that requires no excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, jack the pipeline into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunneling machine from the working pit through the soil layer and lift it into the receiving pit. The pipeline follows the tool pipe or tunneling machine and is buried between the two pits.
