DRAIN PIPE REPAIR METHOD
PROBLEM TO BE SOLVED: To provide a drain pipe repair method capable of preventing a defect due mainly to fluctuation in pressure inside a drain pipe while the same is repaired.SOLUTION: A method for repairing a drain pipe 2, which has: a vertical pipe section 3 which is installed in a manner that vertically penetrates respective floors of a building 1; and drainage joints 4 installed at a plurality of locations in an intermediary section of the vertical pipe section 3, renews the vertical pipe section 3 and the drainage joints 4 in a descending order or an ascending order. When temporarily stopping repair work, the method for repairing the drain pipe 2 installs at least either negative pressure alleviation means 24 to alleviate negative pressure or positive pressure alleviation means to alleviate positive pressure at a place close to a connection member 23 temporarily installed at a boundary between a renewed section 21 and an existing section 22.SELECTED DRAWING: Figure 5
【課題】主に、排水管の改修中における管内圧力の変動による不具合を防止し得る排水管の改修方法を提供する。【解決手段】建物１の内部に各階を上下に貫くように設置されている縦管部３と、この縦管部３の中間部分に複数設けられている排水用継手４とを有する排水管２の改修方法において、縦管部３および排水用継手４を、下側または上側から順に更新して行く。そして、施工の一時中断時に、更新部分２１と既存部分２２との境界部分に一時的に設けられる接続部材２３の近傍に、負圧を緩和するための負圧緩和手段２４、または、正圧を緩和するための正圧緩和手段の少なくとも一方を設置する。【選択図】図５
