PURPOSE:To achieve cost reduction and to shorten the work period by lining only the part to be repaired of a pipeline with a tubular lining material impregnated with a curable resin. CONSTITUTION:A tubular lining material 1, a balloon body 2 and a protective capsule 7 covering both of them are inserted in a pipeline 9 having a damaged part 9a from a manhole 11 in a unified state. After the tubular lining material 1, the balloon body 2 and the protective capsule 7 are accurately moved to the position of the damaged part by a television camera 19, the protective capsule 7 is detached from the lining material 1 and the balloon body 2 and, when the balloon body 2 is filled with hot water, said balloon body 2 is expanded by the pressure of hot water to press the tubular lining material 1 to the inner peripheral wall containing the damaged part 9a of the pipeline 9. At this time, since the thermosetting resin infiltrated in the tubular lining material 1 is cured by the hot water, the tubular lining material 1 becomes a rigid body in the state pressed to the wall of the pipeline. |
