[0002] Pipe jacking is a trenchless construction method, a technique for burying pipes with minimal or no excavation. Pipe jacking involves using the jacking force generated by jacking equipment within a working pit to overcome friction between the pipe and the surrounding soil, pushing the pipe into the soil according to the designed slope, and removing the soil. After one section of pipe is pushed into the soil, the second section is lowered and pushed forward. Using the thrust of the main jacking cylinder and other components such as the pipe and relay rooms, the tool pipe or tunnel boring machine is pushed from the working pit through the soil and hoisted into the receiving pit. The pipeline is then buried between the two pits, following the tool pipe or tunnel boring machine.

During the jacking construction of the pipe jacking machine, the cutterhead is likely to cause disturbance of the soil layer around the jacking direction when drilling and excavating, which may easily cause soil collapse and affect the surrounding structures, thereby causing hidden dangers of engineering accidents.
