Part regeneration repair jig and regeneration repair construction method

摘要

PROBLEM TO BE SOLVED: To provide a fixture for partially regenerating and repairing a feed pipe in a simple and appropriate manner, and a technique. ;SOLUTION: A cylindrical fixture 1 is introduced into a cheese 2 from a cheese fitting hole 21 and then is fitted into the cheese 2, and a liquid resin B required for lining the internal face of a feed pipe 4 between a service cheese 31 and the cheese 2, is introduced, in a plug shape, into a pipe from the opening part of the fixture 1 as a first step. Further, the total amount of a resin plug A is transferred to a point near the service cheese 31 with a liquid flow pressure-injected from behind. In a second step, the liquid flow in the pipe is sucked and drained by a suction means 92 connected to the opening part of the fixture 1. Finally the resin B is applied to the internal face of the pipe by the fluidization of the resin plug A which is pulled back to the opening part of the fixture 1 on account of a suction force for draining the liquid flow.;COPYRIGHT: (C)1998,JPO
