To provide a rainwater drain pipe structure capable of stably merging of drainage from a branch pipe to a main pipe at a confluence part when applying the siphon phenomenon to drain rainwater.SOLUTION: A rainwater drain pipe structure 100 includes: a siphon type drainage member placed on the upper floors; a main pipe 122 for allowing rainwater flowing in from the siphon type drainage member to flow down from the upper floors to the lower floors; and a branch pipe 150 connected to a confluence part 120T that is located in the middle of the height direction of the main pipe 122 for allowing drain water to flow into the confluence part 120T from outside. The main pipe 122 includes: a first vertical pipe 123 placed at the upper side; and a curing tube 125 placed at the lower side of the first vertical pipe 123, which has a flow passage area larger than that of the first vertical pipe 123.SELECTED DRAWING: Figure 4
【課題】サイフォン現象を適用して雨水を排水する際に、合流部において、枝管から本管に安定して排水を合流させることが可能な雨水排水配管構造を提供すること。【解決手段】雨水排水配管構造１００であって、上層階に配置されたサイフォン式排水部材と、前記サイフォン式排水部材から流入する雨水を前記上層階から前記階下に向かって流下する本管１２２と、前記本管１２２の高さ方向における途中に位置される合流部１２０Ｔに接続され、前記合流部１２０Ｔに外部から排水を流入させる枝管１５０と、を備え、前記本管１２２は、上方側に配置される第１縦配管１２３と、前記第１縦配管１２３の下方側に配置され前記第１縦配管１２３よりも大きな流路面積を有する養生管１２５と、を備えることを特徴とする。【選択図】図４
