PROBLEM TO BE SOLVED: To provide a repair structure of a conduit line, capable of utilizing heat possessed by water flowing in the repaired conduit line, and a repair method for realizing the repair structure.SOLUTION: A conduit line is repaired by connecting and arranging assemblies A, B in which a plurality of segments 2 to 4 each provided with ribs 5b, 5c on the outer periphery are assembled in the circumferential direction in the axial direction inside the conduit line to be repaired. A storage recess C for storing heat-exchange members D is formed in inner peripheral surfaces of the segments 3, 4 arranged on a bottom part 1a of the conduit line to be repaired. When the conduit line to be repaired is repaired, the storage recesses are continuously configured in the bottom part in the axial direction, the heat-exchange members are stored in the storage recesses while an opening 9 is shielded by a cover member E. Holes 6 through which optical fibers pass are formed in the rib 5c of the segment 2 arranged in an upper part of the conduit line, and holes 6 are penetratingly formed in an upper part of a repaired conduit line F in the lengthwise direction. |
