〔実施例］
以下、この発明に係る雨水貯留浸透装置を図示する一実
施例に基づいて説明する。[Example] Hereinafter, a description will be given based on an example illustrating a rainwater storage and infiltration device according to the present invention.
第１図はこの発明に係る雨水貯留浸透装置を示したもの
で、図中、番号工は雨水調節枡、２は雨水貯留浸透槽で
あり、いずれも、一体式若しくは組み立て式の鉄筋コン
クリート製であって、工場生産されている。Figure 1 shows a rainwater storage and infiltration device according to the present invention. In the figure, the numbered structure is a rainwater control tank, and 2 is a rainwater storage and infiltration tank, both of which are made of reinforced concrete, either integral or prefabricated. It is manufactured in a factory.
また、雨水調節枡１及び雨水貯留浸透槽２は、いずれも
、地盤中に埋設され、且つ、雨水貯留浸透槽２の回りに
は砕石若しくは砂利３が厚めに充填されている。Furthermore, both the rainwater control tank 1 and the rainwater storage and infiltration tank 2 are buried in the ground, and the area around the rainwater storage and infiltration tank 2 is filled with crushed stone or gravel 3 thickly.
雨水調節枡１には、雨水引き込み管４、雨水放流管５及
び雨水送水管６がそれぞれ接続されている。A rainwater intake pipe 4, a rainwater discharge pipe 5, and a rainwater transmission pipe 6 are connected to the rainwater control cell 1, respectively.
雨水引き込み管４は雨水調節枡１の上端部に接続され、
この雨水引き込み管４より雨樋や側溝等に集められた雨
水が、雨水調節枡１に流れ込むようになっている。The rainwater inlet pipe 4 is connected to the upper end of the rainwater control tank 1,
Rainwater collected in rain gutters, side gutters, etc. flows from this rainwater inlet pipe 4 into the rainwater control tank 1.
雨水放流管５は雨水調節枡１の底近くに接続され、この
雨水放流管５より雨水調節枡Ｉに溜められた雨水が近く
の下水道に直接放流されるようになっている。A rainwater discharge pipe 5 is connected near the bottom of the rainwater control cell 1, and the rainwater stored in the rainwater control cell I is directly discharged from the rainwater control cell 1 to a nearby sewerage system.
なお、雨水放流管５は雨水調節枡Ｉの底に接してではな
く、底よりやや上がった位置に接続されている。The rainwater discharge pipe 5 is not connected to the bottom of the rainwater control cell I, but is connected to a position slightly above the bottom.
したがって、土砂や浮遊物は底に堆積し、雨水と共に放
流されることはない。Therefore, sediment and suspended matter are deposited on the bottom and are not discharged with rainwater.
また、底に堆積した土砂や浮遊物は定期的に取り除くこ
とができる。In addition, sediment and suspended matter that has accumulated on the bottom can be removed periodically.
雨水放流管５の入り口部Ａには、雨水放流調節開閉弁７
が取り付けられている。At the entrance part A of the rainwater discharge pipe 5, there is a rainwater discharge adjustment opening/closing valve 7.
is installed.
雨水放流調節開閉弁７は取付ビン８を軸に上下方向に回
転することにより、自由に開閉することができ、その上
端部にはアーム部９が延在されている。The rainwater discharge regulating on-off valve 7 can be freely opened and closed by rotating vertically about the mounting bin 8, and has an arm portion 9 extending from its upper end.
アーム部９は雨水送水管６の接続口位置よりやや上まで
延在され、その先端部にフロー目。The arm portion 9 extends slightly above the connection port position of the rainwater transmission pipe 6, and has a flow hole at its tip.
が取り付けられている。is installed.
雨水送水管６は雨水引き込み管４の注ぎ口よりやや下が
った位置に接続され、この雨水送水管６より雨水調節枡
ｌ内の雨水が、雨水貯留浸透槽２に送水されるようにな
っている。The rainwater transmission pipe 6 is connected to a position slightly lower than the spout of the rainwater inlet pipe 4, and the rainwater in the rainwater control tank 1 is sent from this rainwater transmission pipe 6 to the rainwater storage infiltration tank 2. .
また、雨水調節枡１の上端部には、蓋１１が取り付けら
れ、いつでも、地上より開けて中を検査したり、中を掃
除できるようになっている。A lid 11 is attached to the upper end of the rainwater control tank 1, so that it can be opened from the ground to inspect or clean the inside at any time.
雨水貯留浸透槽２の側部には、複数個の浸透溝１２．・
・・が縦縞の格子状に形成され、この浸透溝１２．・・
・より雨水貯水浸透槽２に注ぎ込まれた雨水が、周辺の
砕石乃至砂利３の層を通って地盤中に徐々に浸透するよ
うになっている。A plurality of infiltration grooves 12.・
... are formed in a grid pattern of vertical stripes, and these penetration grooves 12.・・・
-Rainwater poured into the rainwater storage and infiltration tank 2 gradually permeates into the ground through the surrounding crushed stone or gravel layer 3.
このような構成に於いて、雨水調節枡１内の水位がａに
至までの間は、雨水放流調節開閉弁７は自重により閉じ
たままの状態にある。In such a configuration, until the water level in the rainwater control tank 1 reaches a level a, the rainwater discharge control valve 7 remains closed due to its own weight.
したがって、放流管５からの放流はなく、雨水調節枡１
内の雨水は、専ら、雨水送水管６を通って雨水貯留浸透
槽２内へ流れ込む。Therefore, there is no discharge from the discharge pipe 5, and there is no discharge from the rainwater control tank 1.
The rainwater inside exclusively flows into the rainwater storage infiltration tank 2 through the rainwater transmission pipe 6.
しかし、豪雨等で降雨量が大幅に増え、水位がｂに至り
、フロー）１０が水没すると、取付ビン８を中心とする
フロート１０の浮力にょるモーメントが、蓋１１の自重
によるモーメントより大きくなる為、フローＮＯは移動
しく図中想像線で図示）、これに伴い雨水放流調節開閉
弁７が開き、放流管５がらも放流される。However, when the amount of rainfall increases significantly due to heavy rain, etc., and the water level reaches b, and the flow 10 is submerged, the moment due to the buoyancy of the float 10 centered on the mounting bin 8 becomes larger than the moment due to the own weight of the lid 11. Therefore, the flow NO moves (as shown by an imaginary line in the figure), and accordingly, the rainwater discharge adjustment on-off valve 7 opens, and the discharge pipe 5 also discharges water.
そして、雨水調節枡１内の水位がａまで下がると、今度
は取付ビン８を中心とする蓋１１の自重によるモーメン
トのほうが、フロート１ｏの浮力によるモーメントより
大きくなる為、蓋１１は閉じ、放流管５からの放流は止
まる。。When the water level in the rainwater control tank 1 drops to a, the moment due to the weight of the lid 11 centered on the mounting bin 8 becomes larger than the moment due to the buoyancy of the float 1o, so the lid 11 is closed and the water is discharged. The discharge from pipe 5 is stopped. .
よって、豪雨時等に於ける降雨水の一時的流出を防止調
節することができる。Therefore, it is possible to prevent and adjust the temporary outflow of rainwater during heavy rains and the like.
この発明は以上の構成からなるので以下の効果を有する
。Since the present invention has the above configuration, it has the following effects.
豪雨時等に於ける降雨水の一時的流出を防止調節するこ
とができ、洪水による災害を防止することができる。It is possible to prevent and control the temporary outflow of rainwater during heavy rains, etc., and disasters caused by flooding can be prevented.
また、地盤面下に完全に埋設されるものである為、従来
必要であった調整池用の広大な土地を他の用途に活用す
ることができ、用地の有効利用が可能である。Additionally, since it is completely buried beneath the ground surface, the vast amount of land traditionally required for a regulating pond can be used for other purposes, making effective use of land possible.
さらに、動力を一切必要としない為、極めて経済的であ
る。Furthermore, since no power is required, it is extremely economical.
