BACKFLOW PREVENTION DEVICE FOR SEWAGE BASIN
PROBLEM TO BE SOLVED: To inexpensively prevent backflow of sewage to a sewage source in a house from a sewage basin into which rainwater is led.SOLUTION: An excess water outlet 11 that opens on a ground outside of a house 1 is communicated with a rainwater lead-in pipe 4 communicated with a sewage basin 2 that stores and discharges sewage from the house 1, and a flow amount restrictor 24 is provided at a location closer to the sewage basin 2 than the excess water outlet 11, for restricting an amount of rainwater flowing into the sewage basin 2 so that the sewage basin 2 would not be full. A cover 16 may be provided that normally closes the excess water outlet 11 but automatically opens the excess water outlet 11 when water pressure inside the rainwater lead-in pipe 4 rises. The flow amount restrictor 24 may also adjust an amount of rainwater flowing into the sewage basin 2.SELECTED DRAWING: Figure 1
【課題】 雨水が導入される汚水桝から住宅内の汚水源へ向けて汚水が逆流することを低コストで防止する。【解決手段】 住宅１の汚水を貯留して排出するための汚水桝２に連通する雨水導入管４に、前記住宅１の外部で地上に開口する過剰水排出口１１が連通され、前記過剰水排出口１１よりも前記汚水桝２に近い位置に、前記汚水枡２への雨水の流入量を前記汚水枡２が満杯とならない量に制限する流量絞り２４が設けられる。前記過剰水排出口１１を常時は閉じ、且つ、前記雨水導入管４内の水圧によって前記過剰水排出口１１を自動的に開放する蓋１６を設けることもできる。また、前記流量絞り２４を、前記汚水桝２への雨水の流入量を調整可能なものとすることもできる。【選択図】 図１
