<p>PURPOSE: To apply a repair member to a leakage place in the flow passage inner wall surface of a gas pipe, the pipeline of waterworks, sewageworks, or the like, or a lining place for reinforcement from the inside with a passage left in the installed state. CONSTITUTION: At the time of repairing a leakage place L in a pipeline T, a pressure body 2 with a small diameter is inserted in the pipeline T. The pressure body 2 is a cylindrical packer 21 formed of elastic material closed inside and having an expansion part 22. A release agent R is applied to the peripheral part of the packer 21, and a repair member P is further laminated thereon so as to form a device expanded by a fluid. When the packer 21 is expanded to come in pressure contact with the leakage place L, the repair member P expanded along with the packer 21 is pressure-fitted to the leakage place L, and the packer 21 is contracted to transfer-fix the repair member P to the leakage place L. The packer 21 is then removed from the hardened repair member P. The repair member 2 is formed of epoxy resin, two-liquid hardened resin, formed in a patty state, and the hardened state is controlled by heating.</p> |
