[0002] For sewage pipe networks in water environments, the pipe networks are usually less than 2m. For sewage pipe networks crossing major traffic routes, in order to reduce interference with traffic and avoid large excavation, pipe networks with a buried depth of more than 3m can be connected to the sewage pipe networks by artificial jacking construction. The technical principle of jacking construction is to make a working well and a receiving well between the pipelines being constructed, and with the help of the thrust of the oil cylinder, the prefabricated concrete pipe is pushed from the working well to the receiving well. This is a construction method for laying underground pipes that does not require excavation of the road surface.

[0003] The jacking construction technology is a construction method that uses 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. It has the advantages of being able to cross obstacles for construction, small construction impact, and high civilized construction. The pipe interface form and double guide control in this technology are the key points of this technology. Flexible sealed self-locking socket joint solid wall pipe sections are selected. Under the combined action of soil friction, jacking force and traction during the jacking process, they are locked into a rigid body, reducing the risk of pipeline disconnection and cracking. For this reason, this plan proposes a jacking pipe for underground pipe network construction. Utility Model Content
