摘要

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

SOLUTION: This cable housing pipe repairing method includes: a step of enclosing an existing cable 4 with a tubular protective material 30; a step of enclosing the existing cable 4 with the lining material 6 by a coupling means 9 for annularly coupling the lining material 6; a step of laying a pressurizing tube 31 having a plurality of flow paths between the existing cable 4 and the lining material 6; a step of pressuring the plurality of flow paths of the pressurizing tube 31 to bulge the tube, allowing the lining material 6 to abut on the inner surface of a protective pipe 2 and curing the lining material 6; a step of removing the pressurizing tube 31 after the predetermined time elapses; and a step of removing the tubular protective material 30 after removing the pressurizing tube 31.
