EXHAUST PRESSURE PIPING
To provided exhaust pressure piping capable of efficiently suppressing the destruction of water seal in a building by a small number of pressure release means.SOLUTION: There is provided exhaust pressure piping comprising a piping body 10 leading from a drainage system to a sewerage system, a plurality of rising pipes 20, 20.. provided in the piping body 10, and pressure release means 30 releasing the internal pressure inside the piping body 10 to the outside. The pressure release means 30 is installed in the rising pipe 20 of the plurality of rising pipes 20, 20.. located in a pressure rise generating section 12 having an opposite end wall 13 that opposes the reverse flow of the internal pressure increased in the piping body 10.SELECTED DRAWING: Figure 1
【課題】少数の圧力開放手段によって建物内の封水破壊を効率的に抑制できる排圧配管を提供する。【解決手段】排水設備から下水道へと至る配管本体部１０と、配管本体部１０に設けられた複数の立上り管２０，２０・・と、配管本体部１０内の内圧を外部に開放する圧力開放手段３０と、を備えている。圧力開放手段３０は、複数の立上り管２０，２０・・のうち、配管本体部１０で高まった内圧の逆流に対向する対向端壁部１３を備えた圧上昇発生部１２に位置する立上り管２０に設置されていることを特徴とする。【選択図】図１
