COMMON CONDUIT WITH RAINWATER STORAGE FUNCTION
To provide a common conduit maintained without cost and spending time that has a rainwater storage function on a narrow road with a road width of 3.5 to 6.5 m in a flood inundation assumed area of an existing urban area.SOLUTION: An internal space of a common conduit with a rainwater storage function (hereinafter referred to as a common conduit) is divided into two spaces, "upper lifeline storage space" and "lower waterway space", by "a receiving rod that is a receiving tool for a lifeline", and a "side conduit type common conduit with a reverse cross slope" is installed at an end part of a road in addition to the common conduit.SELECTED DRAWING: Figure 1
【課題】 既成市街地の洪水浸水想定区域において、道路幅員が3.5~6.5mと狭い道路に雨水貯留機能を持つ共同溝をコストと時間をかけずに整備する。【解決手段】 雨水貯留機能を持つ共同溝(以下、前記共同溝という。)の内部空間を「ライフラインの受け具である受け棒」により「上部のライフライン収納空間」と「下部の水路空間」の二つの空間に分け、前記共同溝とは別に、道路端部に「逆の横断勾配を持つ側溝型の共同溝」を設置することで上記の課題を解決した。【選択図】図1
