To cut water easily and properly in a joint part between an attachment pipe joined to a drainage main pipe and a renewed pipe while preventing complication of installation work of the renewed pipe on the drainage main pipe.SOLUTION: An existing pipe renewal method includes: a renewed pipe installation step K1 in which a renewed pipe 3 is installed in a drainage main pipe 1 buried in the ground; a joint part specifying step K2 in which a joint part 23 of the renewed pipe 3 located below a joint position 22 between an attachment pipe 2 and the drainage main pipe 1 is specified; a water stop material supply step K3 in which a supply hose 61 is inserted into the attachment pipe 2 to supply a water stop material 60 for sealing a gap between the renewed pipe 3 located at the joint part 23 and the drainage main pipe 1; and an opening formation step K4 in which a drilling machine is placed into the renewed pipe 3 and drilling work of the renewed pipe 3 is performed based on specific information of the joint part 23 to form an opening 25 communicating with the attachment pipe 2 in the renewed pipe 3.SELECTED DRAWING: Figure 8
【課題】排水用主管に対する更生管の設置作業が煩雑になることを防止しつつ、排水用主管に接合された取付管と更生管との接合部を容易かつ適正に止水する。【解決手段】地中に埋設された排水用主管１に更生管３を設置する更生管設置工程Ｋ１と、前記取付管２と前記排水用主管１との接合位置２２の下方に位置する前記更生管３の接合部２３を特定する接合部特定工程Ｋ２と、前記取付管２内に供給ホース６１を挿入し、前記接合部２３に位置する前記更生管３と前記排水用主管１との間を封止する止水材６０を供給する止水材供給工程Ｋ３と、前記更生管３内に穿孔装置を進入させ、前記接合部２３の特定情報に基づいて前記更生管３の穿孔作業を行うことにより、前記取付管２に連通する開口部２５を前記更生管３に形成する開口部形成工程Ｋ４と、を備えている。【選択図】図８
