The effective pipe construction method applied in the non-excavation construction project is an underground pipeline construction method developed after the shield construction method. It does not need to excavate the surface layer and can cross roads, railways and rivers. , ground buildings, underground structures and various underground pipelines.
At present, there are many different types of Chongqing pipe jacking machines on the market. The main difference lies in the balance of earth pressure and groundwater pressure and the way the working face is driven. The pipe jacking machine can be divided into two basic types:
1 Open pipe jacking machine: This pipe jacking machine has no pressure sealing zone between the working face and the subsequent pipe. The advantage is that the worker can easily enter the working face.
2 Closed pipe jacking machine: also called closed pipe jacking machine, there is a pressure partition between the excavation surface of the pipe jacking machine and the working room. According to the different balance medium used by the Chongqing pipe jacking machine, It is a pneumatic balance pipe jacking machine, a muddy water balance pipe jacking machine and a soil pressure balance pipe jacking machine.
