REPAIRING METHOD OF EXISTING UNDERGROUND CONDUIT FOR WATER CHANNEL
To provide a repairing method of an existing underground conduit for water channel, the method being capable of reconstituting easily, safely, and inexpensively a new water channel with a new conduit 3 in which multiple connection pipes 5 are consecutively coupled in an existing underground conduit 2.SOLUTION: A repairing method of an existing underground conduit for water channel includes: inserting consecutively-added connection pipes 5 into the existing underground conduit 2 between two adjacent manholes 1 from each of them until both of front end parts of the consecutively-added connection pipes 5 reach the middle part; further pushing in or drawing out at least one of the consecutively-added connection pipes, causing an expanded connection guide mechanism 7 to guide the connection pipes, adjusting position displacement, and completing the connection; performing contraction/removal of the connection guide mechanism 7; and reconstituting a new water channel 4 with a new conduit 3.SELECTED DRAWING: Figure 2
【課題】既設埋設管２内に連結管５が多数連結した新管３による新水路を再構築することが容易にして安全・安価に実現できる水路用の既設埋設管補修方法を提供すること。【解決手段】マンホール１間の既設埋設管２内に双方から挿入した継ぎ足し連結管５の挿入前端部同士を中間部に到達するまで挿入し、さらに少なくとも一方の前記継ぎ足し連結管５を押し込んでまたは引き込んで、膨張した前記連結用ガイド機構７により案内させ位置ずれを修正して連結を完了させ、連結用ガイド機構７は収縮除去して、新管３による新水路４を再構築する水路用の既設埋設管補修方法。【選択図】図２
