To improve adhesion strength of an adhesive agent injected between an existing pipe and a regeneration pipe in an existing pipe regeneration method.SOLUTION: In a regeneration method of an existing pipe 2, following processes are successively executed, that is, a lining process for lining a resin regeneration pipe 3 on an inner side of the existing pipe 2 while expanding its diameter, here, a tube 10 is inserted between the existing pipe 2 and the regeneration pipe 3 in the lining process, a sealing process for sealing the whole periphery between a pipe end 2a of the existing pipe 2 and the regeneration pipe 3 by a cut-off material 20, an adhesive primer injection process for injecting an adhesive primer between the existing pipe 2 and the regeneration pipe 3 through the tube 10, and an adhesive agent injection process for injecting an adhesive agent between the existing pipe 2 and the regeneration pipe 3 through the tube 10.SELECTED DRAWING: Figure 4
【課題】 既設管更生方法において、既設管と更生管との間に注入された接着剤の接着強度を高める。【解決手段】既設管２の更生方法は、次の工程を順に実行する。既設管２の内側に樹脂製更生管３をその拡径を伴ってライニングするライニング工程。このライニング工程においてチューブ１０を既設管２と更生管３との間に挿入する。既設管２の管端２ａと更生管３との間を全周にわたり止水材２０で封止する封止工程。チューブ１０を介して接着プライマーを既設管２と更生管３との間に注入する接着プライマー注入工程。チューブ１０を介して接着剤を既設管２と更生管３との間に注入する接着剤注入工程。【選択図】図４
