METHOD FOR REPAIRING DUCT FACILITIES

摘要

PROBLEM TO BE SOLVED: To provide a method for repairing duct facilities using a rehabilitation pipe that allows less deformation under an external force with high strength structure for repairing duct.

SOLUTION: Segment members 1 integrally formed of plastic of an inner surface plate for constituting an inner circumference and external wall plates standing on the periphery of the inner surface plate are connected in the circumferential direction and in the longitudinal direction of a duct for installing a rehabilitation pipe. A wire 34 is fixed to a pipe unit produced by connecting the segment members in the circumferential direction, surrounding the outer periphery thereof. The pipe units are connected in the longitudinal direction with a joint member 11. When the pipe units are connected in the longitudinal direction, the wire is press-contacted or coupled with the joint member. The coupling of the wire and the joint member allows the pipe unit to be less deformed, resulting in enhancing the strength of the rehabilitation pipe itself.
