DUCT REINFORCEMENT CONSTRUCTION METHOD, DUCT RENEWAL CONSTRUCTION METHOD, AND DUCT REINFORCEMENT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a duct reinforcement construction method which inhibits deformation of a duct and leakage from the duct.;SOLUTION: A duct reinforcement construction method includes: a coating step where a first elastic resin is applied to a leakage inhibition object portion (for example, a crack Cr) of a duct 1 to form a coat 14 coating the leakage inhibition object portion with the first resin; and a filling step where a periphery of the duct is filled with a second resin 19 having rigidity higher than that of the first resin to form a resin layer that integrally coats surfaces of the coat and the duct.;COPYRIGHT: (C)2016,JPO&INPIT
