RAINWATER CONTROLLER AND RAINWATER CONTROL METHOD
PROBLEM TO BE SOLVED: To provide a rainwater controller that prevents excess rainwater from flowing into a sewerage system from a downpipe of a house.SOLUTION: A connection box 17 disposed to enclose a downpipe 10 has an inward-facing flange 18 at a bottom edge and at least a part of a top edge open. The inward-facing flange 18 is connected fluid-tightly to an outer peripheral surface of a lower gutter 14. An inner part of the downpipe 10 communicates with an inner part of the connection box 17, and a size of a space defined by the downpipe 10 and the connection box equals a size of a storage tank 19 for excess water. A flow amount throttle 24 is provided inside the lower gutter 14. The open top edge part of the connection box 17 serves as a drainage port 20 for excess water. Rainwater restricted by the flow amount throttle 24 is stored in the storage tank 19. The rainwater stored in the storage tank 19 flows out naturally through the flow amount throttle 24 at a time of torrential rain, during which a heavy rainfall is observed repeatedly, so that the storage tank is virtually emptied in about 15 to 60 minutes before a next heavy rainfall starts after a previous heavy rainfall subsided.SELECTED DRAWING: Figure 2
【課題】住宅の縦樋から下水道へ向けて雨水が過剰に流入することを防止する雨水制御装置を提供する。【解決手段】縦樋１０を包み込むように配設される連結ボックス１７は、下端に内向きフランジ１８を備えるとともに上端の少なくとも一部が開放され、内向きフランジ１８は、下側樋１４の外周面に対して液密に連結される。縦樋１０の内部が連結ボックス１７の内部に連通しており、縦樋１０とで画成される空間が過剰水の貯留タンク１９の大きさとなる。下側樋１４の内部に流量絞り２４が設けられ、連結ボックス１７の上端開放部が過剰水排出口２０となり、流量絞り２４で制限された雨水は貯留タンク１９に貯留される。強い雨を何回も繰り返す集中豪雨の際に、一回の豪雨が収まった後、次の豪雨が来るまでの間に１５分から６０分程度で前記貯留タンクが実質的に空になるように、貯留タンク１９に貯留された雨水が流量絞り２４を通って自然に流れ出る。【選択図】図２
