CRUSHING METHOD OF SEWAGE PIPE AND REMOVAL METHOD OF SEWAGE PIPE
PROBLEM TO BE SOLVED: To provide a crushing method of sewage pipe and a removal method of the sewage pipe, capable of surely breaking an existing sewage pipe in a present position.SOLUTION: A crushing method comprises a process of arranging a flexible pipe having an explosive device in a sewage pipe, a process of filling a pressure medium in the sewage pipe and a process of breaking the sewage pipe by detonating the explosive device, and comprises a process of inserting a traction member between the sewage pipe and two manholes adjacently arranged to the sewage pipe, a process of pulling a flexible pipe via the traction member in the other manhole via the inside of the sewage pipe from one manhole by installing the flexible pipe in the traction member, a process of filling the pressure medium in the sewage pipe, a process of pulling the explosive device in the flexible pipe and a process of breaking the sewage pipe by detonating the explosive device.
【課題】既設の下水道管を現位置で確実に破壊することが可能な下水道管の破砕工法及び下水道管の撤去工法を提供する。【解決手段】下水道管内に火工品を備えた可撓管を配置する工程と、下水道管内に圧力媒体を充填する工程と、火工品を起爆し、下水道管を破壊する工程とを有する。下水道管に隣接配置される２つのマンホールと下水道管との間に牽引部材を挿通する工程と、牽引部材に可撓管を取り付け、可撓管を一方のマンホールから下水道管内を通して他方のマンホールへ牽引部材を介して引き込む工程と、下水道管内に圧力媒体を充填する工程と、可撓管内に火工品を引き込む工程と、火工品を起爆し、下水道管を破壊する工程とを有する。【選択図】図１
