Pipe jacking construction refers to the construction process of jacking steel pipes (including multi-section steel pipes) or concrete pipes from point A to point B by hydraulic power without digging trenches on the surface. The process principle and process of pipe jacking construction The Ming-laying pipeline is changed to use machinery as the driving force to transfer the pipeline from point A to point B under the surface. The main mechanical equipment includes hoisting equipment, high-pressure oil pumps, large-tonnage jacks, back piles and back beams, guide rails and excavated tools, theodolite, and level. The function and quantity of the machine tools are determined according to the diameter, length and weight of the pipe section being pushed into.

Pipe jacking engineering is a sub-subject of trenchless engineering or a process of trenchless engineering construction. It is a construction technology that passes pipelines through auxiliary equipment without excavation surface, and can pass through roads, railways, rivers, ground buildings, underground structures, and various underground pipelines. The pipe jacking project mainly relies on the thrust of the main jacking cylinder and the relay room between the pipelines to push the tool pipe or the roadheader from the working well through the soil to the receiving well and at the same time push the pipeline into the working hole. The pipeline is pushed in by the main jacking cylinder, and people usually call this kind of project a pipe jacking project.

Process characteristics and scope of application: Pipe jacking under the road, and the road is unblocked; the pipe jacking under the building does not affect the function of the building; shortens the pipeline laying cycle and reduces the project cost significantly; the equipment is single and the operation is simple; it is suitable for railways, highways and difficult or Underground pipeline construction that is not suitable for trench excavation.
