WATER CUTOFF METHOD OF EXISTING PIPE AND WATER CUTOFF STRUCTURE OF EXISTING PIPE
PROBLEM TO BE SOLVED: To easily cut off infiltrated water from an existing pipe to a manhole.SOLUTION: A water cutoff method of an existing pipe, where an existing pipe 31 communicates with a manhole 32, includes a regeneration pipe arrangement step of arranging a regeneration pipe 40 on an inner surface of the existing pipe 31, and projecting a pipe end part 42 of the regeneration pipe 40 from the inside of the existing pipe 31 to the inside of the manhole 32; an elastic body arrangement step of arranging an annular elastic body 11 on an outer periphery of the pipe end part 42; and a holding step of arranging an annular pressing member 12 on the outer periphery of the pipe end part 42 and holding the elastic body 11 between a manhole wall 30 and the pressing member 12 to elastically deform the elastic body, and pressure-welding the elastic body 11 to outer peripheral surfaces of the manhole wall 30 and the regeneration pipe 40.SELECTED DRAWING: Figure 2
【課題】既設管から人孔への浸入水を容易に止水する。【解決手段】既設管の止水方法は、人孔３２に連通する既設管３１の止水方法であって、既設管３１の内面に更生管４０を配置するとともに、更生管４０の管端部４２を既設管３１内から人孔３２内に突出させる更生管配置工程と、管端部４２の外周に環状の弾性体１１を配置する弾性体配置工程と、管端部４２の外周に環状の押圧部材１２を配置して人孔壁３０と押圧部材１２との間に弾性体１１を挟み込んで弾性変形させ、弾性体１１を人孔壁３０および更生管４０の外周面に圧接させる挟み込み工程と、を備えている。【選択図】図２
