COMMON DITCH HAVING FLOOD COUNTERMEASURE FUNCTION
To provide a common ditch that has additional functions and is easy to maintain despite of a compact and simple structure thereof.SOLUTION: A common ditch 1 has a wide and deep rainwater basin and has a shape as if rainwater basins were connected side by side, which can be installed even in a narrow road by taking in a space occupied by a road gutter. A water collection lid 2 on a surface of the common ditch is also a manhole cover as a lifeline inspection port, as well as a ventilation port for the common ditch. Since the lid is used as a drainage lid as well as an inspection port, many large ventilation holes can be provided, and only natural ventilation inside the common ditch is required, and forced ventilation inside the common ditch is not required. The inside of the common ditch is largely divided into upper and lower parts; the lower part is a rainwater ditch, and a basin for finally collecting rainwater is provided on a bottom part thereof. A part of a catch basin 4 is connected to a sewer pipe for rainwater, and the catch basin that is not connected to the sewer pipe for rainwater is used as an infiltration basin. The infiltration basin mitigates discharge to rivers, etc., and serves as measures against heat islands to maintain water retention.SELECTED DRAWING: Figure 1
【課題】維持管理が容易なコンパクトで単純な構造ながらも付加的な機能を持たせた共同溝を提供する。【解決手段】共同溝１は雨水桝の幅や深さを大きく、雨水桝を並べて接続したかのような形状とし、道路側溝の占める空間も取り入れることで、狭い道路でも共同溝が設置できる。共同溝の表面にある集水蓋２は、ライフラインの点検口としてのマンホール蓋でもあり、共同溝の換気口でもある。蓋が集水蓋かつ点検口であるため、大きな換気口を多く設けることができ、共同溝内部は自然換気だけですみ、共同溝内の強制換気が不要となる。共同溝内部は大きく上下に分かれ、下部は雨水渠であり、その底面部に雨水を最終的に集水する桝を設ける。集水桝４の一部は雨水用の下水道管に接続され、雨水用の下水管に接続されない集水桝を浸透桝とする。浸透桝は、河川などへの放流を緩和させるが、保水性を持たせるヒートアイランド対策を図る。【選択図】図１
