To surely prevent axial elongation and contraction of a regeneration pipe lined on an existing 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 regeneration pipe insertion process for inserting a resin regeneration pipe 3 in a collapsed state to the existing pipe 2, a long member insertion process for inserting a long member 10 along an axial direction of the existing pipe 2, here, the long member is constituted by arranging a plurality of sealing bags 11 in which an adhesive agent 15 (binding material) is sealed, in a longitudinal direction, a process for lining the regeneration pipe 3 on an inner periphery of the existing pipe 2 by expanding a diameter of the regeneration pipe 3, here, the sealing bags 11 rupture so that the adhesive agent 15 is supplied to a clearance between the existing pipe 2 and the regeneration pipe 3, and a sealing process for sealing the whole periphery of a pipe end 2a of the existing pipe 2 and the regeneration pipe 3 by the cut-off material 20.SELECTED DRAWING: Figure 1
【課題】 既設管更生方法において、既設管にライニングされた更生管の軸方向伸縮を確実に禁じる。【解決手段】既設管２の更生方法では、次の工程を順に実行する。潰した状態の樹脂製更生管３を既設管２に挿入する更生管挿入工程。長尺部材１０を既設管２の軸方向に沿って挿入する長尺部材挿入工程。長尺部材は、接着剤１５（拘束材料）を封入した複数の封入袋１１を長手方向に並べることにより構成されている。更生管３を拡径させることにより、更生管３を既設管２の内周にライニングする工程。この際、封入袋１１が破裂して接着剤１５が既設管２と更生管３の隙間に供給される。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。【選択図】図１
