Detachable push bench

Technical Field

The utility model relates to a push pipe construction technical field specifically is a detachable push bench.

Background

Pipe-jacking construction is a trenchless construction method, and is a pipeline burying construction technology with no excavation or less excavation. The pipe jacking construction needs to overcome the friction force between the pipeline and the surrounding soil by means of jacking force generated by jacking equipment in a working pit, jack the pipeline into the soil according to a designed gradient and carry away earthwork. After one section of pipe is pushed into the soil layer, the second section of pipe is pushed into the soil layer continuously. The principle is that by means of the thrust of the main top oil cylinder, the pipeline and the relay, the tool pipe or the development machine is pushed into the receiving pit from the working pit through the soil layer and is lifted. However, the pipe jacking machines of the line segments directly push the pipeline through the hydraulic cylinders, if the extension length of one hydraulic cylinder is different from that of the other hydraulic cylinders, the pipeline is prone to being stressed unevenly and offset when pushed, and therefore pipe jacking construction is affected.
