Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to an auxiliary pipe jacking device for water conservancy construction. Background Art

[0002] Pipe jacking is a trenchless construction method, a pipeline burial construction technology with 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, push 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 tunnel boring machine from the working pit through the soil layer to the receiving pit and lift it. The pipeline follows the tool pipe or tunnel boring machine and is buried between the two pits.
