An object of the present invention is to provide a system that effectively utilizes rainwater that falls on a large roof while solving the above-mentioned problems, and for this purpose, the present invention has developed a system that uses a drainage adjustment tank to collect rainwater that falls on a large roof. Then, the rainwater is guided to the rainwater tank via a control valve and a filter that prevent the water level from exceeding a certain level, and the rainwater stored in the rainwater tank is circulated until it is sent to the usage route by a water condensation pump. The gist is that chlorine is circulated using a pump while injecting chlorine as needed.

図は本発明の雨水利用システムの実施例を示す
概略縦断説面図で、図中１は大屋根１ａを有する
大型建造物である。 The figure is a schematic longitudinal cross-sectional view showing an embodiment of the rainwater utilization system of the present invention, and in the figure 1 is a large building having a large roof 1a.
この建造物１の大屋根１ａに降る雨水を樋その
他の手段で集めるべく地下に雨水槽２を形成する
が、この大屋根１ａと雨水槽２との間に排水調整
槽３を介在させた。 A rainwater tank 2 is formed underground to collect rainwater falling on the large roof 1a of the building 1 using a gutter or other means, and a drainage regulating tank 3 is interposed between the large roof 1a and the rainwater tank 2.
この排水調整槽３は流入側の水路が遮断された
ときは下水本管４に雨水を流出させるもので、そ
の流入側に沈砂槽５を設け、さらに流入弁６と洗
浄用ポンプ８を備えた回転式の微細網濾過方式の
ろ過器７とを順次配設する。 This drainage regulating tank 3 is for draining rainwater into the main sewage pipe 4 when the waterway on the inflow side is blocked, and is provided with a sedimentation tank 5 on the inflow side, and further equipped with an inflow valve 6 and a cleaning pump 8. A rotary fine mesh filtration type filter 7 is sequentially installed.
該ろ過器７と雨水槽２を結ぶ配管９に緊急閉止

はフロート式の自方式弁を用いる。 The pipe 9 connecting the filter 7 and the rainwater tank 2 is provided with an emergency shutoff valve 10 and an abnormal water level prevention valve 11. The emergency shutoff valve 10 uses a normal rose air-operated valve together with the inflow valve 6 to prevent abnormal water levels. Prevention valve 11
uses a float-type private valve.
一方、雨水槽２はその周囲にオーバーフロー用

かないように制御する。 On the other hand, the rainwater tank 2 has an overflow spring water tank 12 formed around it, and a water level gauge 13 is installed in this rainwater tank 12 to detect the water level up to overflow in about two stages, and the output is used to detect the inflow. The valve 6 and the emergency shutoff valve 10 are closed. 14 in the diagram
is a rain gauge that detects the amount of rain falling on the large roof 1a.
The output of this rain gauge 14 is also introduced into the inflow valve 6, and the inflow valve 6 is controlled not to be opened when the amount of rainfall does not reach a certain value or more.
図中１５は給水用ポンプ１６を途中に設置した

素濃度計２１を取付けている。 In the figure, 15 is a water supply pipe with a water supply pump 16 installed in the middle, which connects the rainwater tank 2 and the place of use. In addition to this water supply pipe 15, the rainwater tank 2 has a circulation pipe 1 equipped with a circulation pump 17 and a chlorine injection device 18.
9, and is further equipped with a pH meter 20 equipped with a pump and a chlorine concentration meter 21.
図中、２２は非常用排水ポンプ２３を設けた非
常用排水管で、湧水槽１２と排水調整槽３とを結

水調整槽３を消防用水の貯水槽と兼用させること
も考えられる。 In the figure, 22 is an emergency drain pipe equipped with an emergency drain pump 23, which connects the spring water tank 12 and the drainage adjustment tank 3. In addition, in order to secure emergency water in the event of a disaster,
It is also conceivable to adopt a system that replenishes tap water so that a certain amount of water is always stored even when there is no rainfall, and to make this drainage adjustment tank 3 also serve as a water storage tank for firefighting water.
次に動作について説明すると、大屋根１ａに降

のように、ろ過器７が雨水槽２の流出側でなく流
入側にあるので雨水槽２の清掃も楽なものとな
り、雨水槽２での水の腐敗も少なくすることがで
きる。また、雨水が雨水槽２へ順次溜つていき、
ある設定水位以上に達すると水位計１３の出力で
流入弁６がまず閉じ、次いでそれ以上の設定水位
になるとフロートの作用により異常水位防止弁１

これらの弁が閉じたときは排水調整槽３へ流れ込
む雨水は下水本管４へと排出される。 Next, to explain the operation, rainwater falling on the large roof 1a is collected in a temporary drainage adjustment tank 3, and from there, before flowing into the rainwater tank 2, it passes through a filter 7 and collected garbage is automatically collected by a pump 8. Washed. In this way, since the filter 7 is located on the inflow side rather than the outflow side of the rainwater tank 2, the rainwater tank 2 can be cleaned easily, and spoilage of water in the rainwater tank 2 can be reduced. In addition, rainwater accumulates in rainwater tank 2,
When the water level reaches a certain set level or higher, the inflow valve 6 is first closed by the output of the water level gauge 13, and then when the water level reaches the set level or higher, the abnormal water level prevention valve 1 is closed by the action of the float.
1 closes. Therefore, it is possible to prevent rainwater from flowing too much into the temporary rainwater tank 2 due to some kind of trouble during localized heavy rains, etc., in three stages using the three safety devices: the inflow valve 6, the emergency shutoff valve 10, and the abnormal water level prevention valve 11.
When these valves are closed, rainwater flowing into the drainage regulating tank 3 is discharged to the sewage main pipe 4.
また、何らかの異常でこれより高いレベルにな
つた水位を越えた場合は、湧水槽１２にオーバー
フローし、ここである程度貯留できその間に非常

計１３の出力で中央監視室にて監視し、警報を発
するようにした。 In addition, if the water level exceeds this level due to some abnormality, it will overflow to the spring water tank 12 and be stored there to some extent. Meanwhile, the emergency drainage pump 23 will be driven to adjust the drainage through the drain pipe 22. Return to tank 3. The water level was monitored in the central monitoring room using the output of the water level gauge 13, and an alarm was issued.
ところで、雨の降り始めは、大屋根１ａに積つ
ているホコリ類を流し込むことが多いので、雨量
計１４で計測し、一定の降雨量以下の時はある一
定時流入弁６を閉止して雨水槽２への集水を行な
わないようにする。 By the way, when it starts to rain, the dust accumulated on the large roof 1a is often washed away, so the rain gauge 14 is used to measure the rainfall, and when the amount of rainfall is less than a certain level, the inflow valve 6 is closed at a certain time to stop the rain. Avoid collecting water into water tank 2.

とにより貯留雨水の腐敗防止を図かる。 The rainwater stored in the rainwater tank 2 in this way is sent to the water supply pump 16 as auxiliary water for the cooling tower, as flushing water for toilet bowls, etc., and to other routes for use. 2 within 1~
The stored rainwater is circulated once or twice every two weeks by a circulation pump 17, chlorine is measured during the circulation, and chlorine is automatically injected by a chlorine injection device 18 to keep the concentration constant, thereby preventing the stored rainwater from decomposing. .

As described above, the rainwater utilization system of the present invention safely and effectively utilizes rainwater that falls on the large roof of a large building with a large roof. By reusing rainwater from the site and artificial ground, we are able to prevent contamination with organic matter, and by using a double slab, which is structurally necessary for the building, as a rainwater tank, a large amount of water can be stored. This makes it possible to further improve efficiency.
