BORING APPARATUS FOR REPAIRING SEWAGE PIPE

摘要

PURPOSE: A cutting and boring apparatus for repairing a sewage pipe is provided to facilitate repair work and reduce construction time and costs by enabling repair work though sewage remains in the sewage pipe. CONSTITUTION: A cutting and boring apparatus for repairing a sewage pipe comprises a moving body(31), a body fixing device(40), a cutting/boring head(50), a cutting actuator(60), a new pipe front assembly(55), and a straight movement guide mechanism(70). The moving body moves in a sewerage pipe. The body fixing device clinches the moving body within the sewerage pipe. The cutting/boring head is located in the front of the moving body and cuts the inner wall of the sewerage pipe. The cutting actuator is formed in the moving body and rotates the cutting/boring head. The new pipe front assembly is positioned in the front of the cutting/boring head and is coupled with the new pipe.
