Description

Technical Field

[0001] The utility model mainly relates to the technical field of pipe jacking construction, in particular to a pipe jacking device for underground pipe network 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.

[0003] However, the existing pipe jacking device is operated in a pit during actual operation. The lifting equipment used is to lift the pipe jacking head to the pipe jacking device located in the pit. When the pipe jacking head is lifted into the pit, the pipe jacking head is connected to the lifting equipment by ropes, and the pipe jacking head shakes or rotates. When the device is installed and fixed on the pipeline, it is easy to cause the pipeline to tilt, affecting the construction. The operator is required to correct and maintain its position, but the space in the pit is small, which is not convenient for the operator to operate. To solve this problem, a pipe jacking device for underground pipeline construction is provided. Utility Model Content
