Pipe jacking construction can be divided into

The technical structure can be divided into the following parts:

1. Mechanical excavation jacking: the pipe jacking is excavated by mechanical excavation equipment, and it will be jacked continuously during the excavation until it reaches the design length.

2. Extrusion jacking: The pipe is pressed into the soil layer by the pressure at the front end of the pipe jacking machine, and the soil in the soil layer is squeezed out of the pipe at the same time, so as to achieve the purpose of jacking.

3. Hydraulic machinery excavation: the pipeline is jacked into the soil layer by hydraulic machinery, and the soil in the soil layer is washed out at the same time to achieve the purpose of jacking.

4. Manual excavation jacking: the pipe jacking is excavated by manual excavation equipment, and it is jacked continuously during the excavation until it reaches the design length.
