Design and Application of a New Supporting Propulsion and Pullback Mechanism for Pipe Jacking Machine
In the construction of urban underground pipeline jacking,it is common to encounter the problem of recycling and reusing prefabricated cement pipes.At the same time,it is hoped that the space for changing the middle knife during the jacking machine construction process can be larger and safer,while traditional relay structures are currently unable to achieve this.In order to solve this construction problem,a special relay jacking system with support and direction adjustment mechanism was designed.This special relay room structure adds front and rear support shoe structures on the basis of the traditional relay room,achieving both forward and backward pushing of the relay room system,thereby achieving the goal of pushing out and reusing prefabricated cement pipes and increasing the front end tool changing space by pulling back the cutterhead.
