METHOD FOR RENEWING SEWERAGE PIPE
PROBLEM TO BE SOLVED: To provide a method for destroying an existing sewerage pipe for certain and laying a new sewerage pipe in place of the destroyed existing sewerage pipe.SOLUTION: A traction member is placed from a first manhole to a second manhole through an existing sewerage pipe. The traction member is fitted on a flexible pipe housing a traction member for a renewal pipe and an auxiliary traction member, and the traction member is pulled for drawing the flexible pipe from the first manhole to the second manhole through the existing sewerage pipe. A pressure medium is filled in the existing sewerage pipe, an explosive device is fitted on the auxiliary traction member, and the auxiliary traction member is pulled to draw the explosive device into the flexible pipe. The explosive device is ignited for destroying the existing sewerage pipe. A thrusting device is installed in the first manhole, while a traction device is installed in the second manhole. The traction member for a renewal pipe is fitted on a first renewal pipe, and subsequent renewal pipes are sequentially pushed in by the thrusting device while pulling the traction member for a renewal pipe with the traction device.
【課題】既設の下水道管を確実に破壊した後、破壊した既設の下水道管の領域に新たな下水道管を敷設する方法を提供する。【解決手段】一方のマンホールから既設の下水管内を通して他方のマンホールへ牽引部材を配置し、更新管用牽引部材及び補助牽引部材を内部に配置した可撓管に牽引部材を取り付けると共に、牽引部材を牽引して可撓管を一方のマンホールから既設の下水道管内を通して他方のマンホールへ引き込み、既設の下水道管内に圧力媒体を充填し、補助牽引部材に火工品を取り付け、補助牽引部材を牽引して可撓管内に火工品を引き込み、火工品を起爆し、既設の下水道管を破壊し、一方のマンホール内に押込装置を配置し、他方のマンホール内に牽引装置を配置し、先頭の更新管に更新管用牽引部材を取り付け、更新管用牽引部材を牽引装置で牽引しながら後続の更新管を押込装置で順次押し込む。【選択図】図１
