CABLE HOUSING PIPE REPAIRING SYSTEM, METHOD THEREOF AND SEPARATING ROTATING TYPE TRACTION DEVICE IN THE REPAIRING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a cable housing pipe repairing method for repairing pipes using a lining material while laying cables existing in a protective pipe of a predetermined pipe coduit.

SOLUTION: The cable housing pipe repairing method includes: a step of enclosing an existing cable 4 with a lining material 6; a step of laying a tube between the existing cable and the lining material; a step of pressuring the flow path of the tube to bulge the tube, allowing the lining material to abut on the inner surface of a protective pipe 2 and keeping the abutting state for a predetermined time to cure the lining material; and a step of removing the tube after the predetermined time elapses. The step of enclosing the existing cable with a lining material includes a step of enclosing the existing cable while tracking the lining material by a separating rotating type traction device having a structure for turnably coupling a rotating member for fixing the lining material and a shaft member for fixing the traction side.
