Description

Push bench based on continuous unearthing of band conveyer

Technical Field

The utility model relates to a push pipe technical field, concretely relates to push pipe machine based on band conveyer goes out native in succession.

Background

The pipe jacking technology is a trenchless tunneling type pipeline laying construction technology used for municipal construction. The method has the advantages of no influence on the surrounding environment or less influence, small construction site and low noise. But also can be deeply operated underground, which is incomparable with the advantages of digging and burying pipes. In the past decades, cities in China develop rapidly, and cities expand rapidly. The pipe jacking construction is widely applied to short-distance underground excavation construction due to the advantages that the open excavation workload is small, and the construction cost is lower than that of a shield method.

During the working process of the conventional pipe jacking machine, muck is discharged from the spiral chip cleaner and is sent into a muck truck through a belt conveyor, and after the muck truck is fully piled, the pipe jacking machine stops tunneling, pulls the muck truck out of a hole and pours out the muck. And then the muck truck is put into the starting well and pulled to the lower part of the belt conveyor, and the pipe jacking machine continues to tunnel. From the above description, the conventional pipe jacking machine has a long stopping time in the construction process, and the stopping time is increased along with the increase of the length of the pipe jacking, so that the tunneling efficiency is low.
