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 with hydraulic power without digging trenches on the surface. Technological principle and technological process of pipe jacking construction The open-laid pipeline is changed to use machinery as power 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 unearthed tools, theodolites, and levels. The function and quantity of the machine tool are determined according to the diameter, length and weight of the jacked pipe joint.

Pipe jacking engineering is a sub-subject in trenchless engineering or a process of trenchless engineering construction. It is a process for passing pipelines through auxiliary equipment without excavating the surface layer, and can cross 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 roadheader from the working well through the soil layer to the receiving well and at the same time push the pipeline into the working hole. The pipeline is propelled by the main jacking cylinder, and people usually call this kind of project a pipe jacking project.
Technological characteristics and scope of application Pipe jacking under the road, the road is smooth; pipe jacking under the building, does not affect the function of the building; shorten the pipeline laying cycle, significantly reduce the cost of the project; single equipment, easy to operate; suitable for railways, highways and difficult or It is not suitable to excavate trenches for underground pipeline construction.
