RAINWATER DRAINAGE SYSTEM AND ON-ROOF STRUCTURE
To provide a rainwater drainage system capable of preventing harms caused by excessive opening of the tail end of a water sprinkling pipe and harms caused by excessive closing.SOLUTION: The rainwater drainage system comprises a water sprinkling pipe 40 connected through a first elbow 18 from a down-pipe 17. At least one opening hole 42 is provided downward in the water sprinkling pipe 40. The lower part of the tail end 44 of the water sprinkling pipe 40 is opened, and an area of the tail end 44 of the water sprinkling pipe 40 is closed by 40-80% with respect to a pipe flow path cross-section area immediately before.SELECTED DRAWING: Figure 2
【課題】散水管の終端の過度な開放による弊害、及び過度な閉塞による弊害を防止できる雨水排水システムを提供する。【解決手段】雨水排水システムは、竪樋１７から第１エルボ１８を介して接続される散水管４０を含む雨水排水システムであって、散水管４０には、少なくとも１つの開口孔部４２が下方に向けて設けられる。散水管４０の終端４４の下方が開口し、かつ、散水管４０の終端４４の面積が直前の管流路断面積に対し４０～８０％閉塞されている。【選択図】図２
