To provide drainage piping that can solve the following problems that: in order to eliminate malfunctions caused by pressure changes in the drainage piping, pressure adjustment mechanisms such as intake valves, exhaust valves, and positive and negative pressure relief devices are sometimes connected to the drainage piping, in such cases, however, these pressure adjustment mechanisms often include moving parts, and if drainage water flowing through the drainage piping comes into contact with the pressure adjustment mechanisms, the moving parts may stop working, causing malfunctions; and although there is a method of making it difficult for the drainage water to flow into the pressure adjustment mechanisms by providing a convex part or the like in a drainage water flow channel, it is difficult to completely prevent the drainage water, and there is also a risk that drainage water performance is deteriorated by the convex part.SOLUTION: Drainage piping is composed of a piping member through which drainage water passes, a branch pipe part provided with an opening part in the side of the piping member and extending from the opening part in a direction of the side of the piping member, a pressure adjustment mechanism for adjusting pressure of air in the piping member connected to the branch pipe part, and a waterproof body that is disposed in the opening part, permits passage of gas and does not permit the passage of a liquid.SELECTED DRAWING: Figure 2
【課題】排水配管には、排水配管内の圧力の変化による不具合を解消するため吸気弁や排気弁、正負圧緩和装置など圧力調整機構が接続される場合がある。しかし、これら圧力調整機構は可動部分を含む構造が多く、排水配管を流れる排水が圧力調整機構に触れると可動部分が動作しなくなり不具合が生じる恐れがある。排水の流路上に凸部等を設けて圧力調整機構に排水が流れ込み難くする方法もあるが排水を完全に防止することは困難であり、また凸部によって排水性能が悪化する恐れもあった。【解決手段】排水配管を、排水が通過する配管部材と、前記配管部材の側面に開口部を設け、前記開口部から前記配管部材の側面方向に延出して設けられた枝管部と、前記枝管部に接続される前記配管部材内の空気の圧力を調整する圧力調整機構と、前記開口部に配置された、気体の通過を許容し、液体の通過を許容しない防水体と、から構成する。【選択図】図２
