REPAIR METHOD OF EXISTING PIPE AND REPAIR STRUCTURE OF EXISTING PIPE
To provide a repair method of an existing pipe which can form a water stop structure which is high in water stop performance to the existing pipe having a pipe structure in which two kinds of pipes which are different from each other in pipe diameters are connected to each other.SOLUTION: An existing pipe comprises a cut first pipe, a second pipe having an inside diameter larger than an inside diameter of the first pipe, and a connecting part for connecting the first pipe and the second pipe. There is employed a repair method of the existing pipe which comprises the steps for: preparing a short pipe having a length reaching a prescribed position of the second pipe from a cut end of the first pipe; inserting the short pipe into the existing pipe from the cut end; deforming a portion in the vicinity of a tip of the short pipe inserted into the pipe so as to be expanded up to a prescribed position; and charging a liquid water stop agent from the cut end of the first pipe so as to fill a clearance between the first pipe and the short pipe, and hardening the water stop agent.SELECTED DRAWING: Figure 9
【課題】管径の異なる２種の管が接続されている管構造を有する既設管に止水性の高い止水構造を形成することができる、既設管の補修方法を提供する。【解決手段】既設管は、切断された第１の管と、第１の管の内径よりも大きい内径を有する第２の管と、第１の管と第２の管とを接続する接続部と、を備え、第１の管の切断端から第２の管の所定の位置まで届く長さを有する、短管を準備する工程と、短管を切断端から既設管の管内に挿入する工程と、管内に挿入された短管の先端付近を、所定の位置で拡張させるように変形させる工程と、第１の管と短管との間の隙間を埋めるように、第１の管の切断端から液状の止水剤を充填し、止水剤を硬化させる工程と、を備える既設管の補修方法を用いる。【選択図】図９
