DRAINAGE COLLECTING PIPE
To provide a drainage collecting pipe made of resin that can reduce noise or vibration caused along with occurrence of swirling flow.SOLUTION: An upper pipe 1100 of a drainage collecting pipe 1000 has a protrusion configured to protrude on an inner periphery in order to change flow of drainage in a direction along which a horizontal branch pipe connection part 1120 is not provided. The protrusion is a drift plate 1200 having a planar surface. The upper pipe 1100 of the drainage collecting pipe 1000 has a recess for forming the protrusion (drift plate 1200) on an outer peripheral surface of the upper pipe 1100 having the protrusion (drift plate 1200). The recess has a rib 1400 including a face perpendicular to a shaft core of the drainage collecting pipe 1000. The rib 1400 has a function to reduce vibration or noise generated when the drainage is discharged on the protrusion (drift plate 1200).SELECTED DRAWING: Figure 3
【課題】旋回流の発生に伴う騒音または振動を低減することができる樹脂製の排水集合管を提供する。【解決手段】排水集合管１０００の上部管１１００は、横枝管接続部１１２０を備えない方向において、排水の流れを変化させるために内周に突出した突起物を備える。突起物は、表面が平面形状を備えた偏流板１２００である。排水集合管１０００の上部管１１００は、この突起物（偏流板１２００）が備えられた上部管１１００の外周面に、突起物（偏流板１２００）を形成するための凹みを備え、この凹みは、排水集合管１０００の軸芯に垂直な面を含むリブ１４００を備える。このリブ１４００は、突起物（偏流板１２００）に排水が当たって発生する振動または騒音を低減する機能を備える。【選択図】図３
