FLOOD PREVENTION SIDE DITCH STRUCTURE
PROBLEM TO BE SOLVED: To provide a flood prevention side ditch structure which can prevent flood such as road flooding even if rainwater exceeds a planned drainage amount from a side ditch.SOLUTION: A flood prevention side ditch structure comprises a water storage basin block 2 that is buried in the ground and that infiltrates rainwater 1 into the ground while storing rainwater, and a hood block 3 mounted on the upper part of the water storage basin block 2. The hood block 3 is provided with a drain ditch 4 exposed to the ground, and the drain ditch 4 is provided with a water-overflow inflow part 5 into which water-overflow 1A exceeding a water-level of a planned drainage amount flows when rainwater 1 flowing into the drain ditch 4 reaches the planned drainage amount or more. The water-overflow inflow part 5 is provided with an overflow water passing part 6 that communicates with the inside of the water storage basin block 2 mounted in the lower part of the hood block 3.SELECTED DRAWING: Figure 3
【課題】側溝の計画排水量を越えても、道路冠水等の洪水が防止される洪水防止側溝構造を提供すること。【解決手段】地中に埋設されて雨水１を貯水しつつ地中へ浸透させる貯水桝ブロック２と、この貯水桝ブロック２の上部に装着される天蓋ブロック３とから成り、前記天蓋ブロック３には、地上に表出させる排水溝４が設けられており、この排水溝４に、この排水溝４内に流れ込む雨水１が計画排水量以上となった際に、この計画排水量の水位を越えた越水１Ａが流入する越水流入部５が設けられ、この越水流入部５に、前記天蓋ブロック３の下部に装着される前記貯水桝ブロック２内へと通ずるオーバーフロー通水部６が設けられている洪水防止側溝構造。【選択図】図３
