REPAIR METHOD FOR PIPE CONNECTION PART OF MANHOLE
To provide a repair method which stops ground water contained in the soil outside of a pipe mounting part of a manhole by a simple method, and which improves efficiency of repair work of a pipe connection part of the manhole.SOLUTION: An injection hole 32 communicating with soil 100 outside a manhole 10 is formed locally by using a drill, at an outer peripheral portion of an existing pipe 14 at a pipe connection part 12 from the inside of the manhole 10. Then, an injection implement 44 is inserted in the injection hole 32, a water-stopping agent is injected in the soil from the injection implement 44 to solidify the water-stopping agent in the periphery of the existing pipe 14, and the water is stopped. After that, the outer peripheral portion of the existing pipe 14 at the pipe connection part 12 is removed.SELECTED DRAWING: Figure 4
【課題】マンホールの管取付部の外側の地盤に含まれる地下水を簡便な方法で止水し、マンホールの管接続部の改修工事を効率化する改修方法を提供する。【解決手段】マンホール１０の内側から管接続部１２における既設管１４の外周部分に、マンホール１０の外側の地盤１００に通じる注入孔３２を、穿孔機を用いて局所的に形成する。次いで、注入孔３２に注入具４４を挿入し、注入具４４から地盤に止水剤を注入して、止水剤を既設管１４の周囲で固化させることにより止水する。その後、管接続部１２における既設管１４の外周部分を取り除く。【選択図】図４
