RAINWATER DRAINAGE SYSTEM
PROBLEM TO BE SOLVED: To make it possible to suppress overflow from a drain pipe cover regardless of a shape of a bent pipe, at the time of concentrated torrential rainfall.SOLUTION: There is provides a rainwater drainage system comprising: an eaves gutter 2 attached to eaves of a roof; a downpipe 3 provided at part of the eaves gutter 2; a horizontal pipe 6 that is connected to the downpipe 3 via an elbow 4, is embedded underground, and is joined by an indoor drain pipe 5; and a basin 7 including a gully 72 provided on the horizontal pipe 6 and a confluence basin 71 connected to the indoor drain pipe 5. Rainwater flows into the eaves gutter 2, passes through the downpipe 3, and is made to flow out to the horizontal pipe 6. Siphon generation parts are provided in the eaves gutter 2 and downpipe 3, and a straightening rib is provided in a passage that is between the downpipe 3 and horizontal pipe 6 and has the elbow 4.SELECTED DRAWING: Figure 2
【課題】集中豪雨時において曲管の形状にかかわらず排水管カバーからのオーバーフローを抑制することができる。【解決手段】屋根の軒先に取り付けられた軒樋２と、軒樋２の一部に設けられる竪樋３と、竪樋３にエルボ４を介して地中に埋設されるとともに室内排水管５が合流する横引き管６と、横引き管６に設けられる雨水枡７２および室内排水管５に接続される合流枡７１からなる枡７と、を備え、軒樋２に流れた雨水を竪樋３を介して横引き管６に流出させるように構成され、軒樋２および竪樋３にサイホン発生部が設けられ、竪樋３と横引き管６との間のエルボ４を有する流路内には整流リブが設けられた構成の雨水排水システムを提供する。【選択図】図２
