To provide a renewal method of an existing pipe buried in the ground along an arrangement path of waterworks and a sewer which renews the existing pipe properly to prevent drain water etc. from entering a gap between an end of a renewed pipe and an end of the existing pipe while preventing high construction costs and extension of a construction period.SOLUTION: A renewal method of an existing pipe 1 buried in the ground along an arrangement path of waterworks and a sewer includes: a renewed pipe installation step K in which a renewed pipe 3 is installed within the existing pipe 1; and a water stop material injection step K4 in which a water stop material formed by a foam resin material is injected into a gap 13 between an end of the existing pipe 1 and an end of the renewed pipe 3. In the water stop material injection step K4, the water stop material 60 is injected into the gap 13 in a state that a tip of a water stop material injection part 61 provided at a water stop material injection device 6 is inserted into the gap 13.SELECTED DRAWING: Figure 7
【課題】上水道又は下水道の配設経路に沿って地中に埋設された既設管の更生方法であって、施工コストが高く付くのを防止するとともに、施工期間が長くなるのを防止しつつ、既設管を適正に更生して、更生管の端部と既設管の端部との隙間に排水等が侵入するのを防止できる既設管の更生方法を提供する。【解決手段】上水道又は下水道の配設経路に沿って地中に埋設された既設管１の更生方法であって、前記既設管１内に更生管３を設置する更生管設置工程Ｋと、前記既設管１の端部と前記更生管３の端部との隙間１３内に、発泡樹脂材からなる止水材を注入する止水材注入工程Ｋ４と、を備え、該止水材注入工程Ｋ４において、止水材注入装置６に設けられた止水材注入部６１の先端を前記隙間１３内に挿入した状態で、該隙間１３内に前記止水材６０を注入する。【選択図】図７
