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 a 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１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 1 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１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 1, 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は取付ピン８を軸に上下方向に回
転することにより、自由に開閉でき、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 a mounting pin 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トＪ０が取り付けられて
いる。The arm portion 9 extends slightly above the connection port position of the rainwater pipe 6, and has a float J0 attached to its tip.
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
１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 intake pipe 4, and the rainwater in the rainwater control cell 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 of vertical stripes, and the penetration grooves 12.・・・
-Rainwater poured into the rainwater storage and infiltration tank 2 gradually permeates into the ground through the surrounding layers of crushed stone or gravel 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は自重により開い
たままの状態にある。In this configuration, until the water level in the rainwater control tank 1 reaches a level a, the rainwater discharge control valve 7 remains open due to its own weight.
したがって、雨水送水管６から雨水貯留浸透槽２内への
送水はなく、専ら、雨水放流管５らの放流のみが行われ
る。Therefore, water is not sent from the rainwater transmission pipe 6 into the rainwater storage infiltration tank 2, and only water is discharged from the rainwater discharge pipe 5.
しかし、豪雨等で降雨量が大幅に増え、水位がｂに至り
、フロートｌＯが水没すると、取付ピン８を中心とする
フロート１０の浮力によるモーメントが、蓋１１の自重
によるモーメントより大きくなる為、フロート１０は移
動しく図中想像線で図示）、これに伴い雨水調節開閉弁
７が閉まり、放流管５からの放流は止まり、雨水送水管
６から雨水貯留浸透槽２内へ雨水の送水が行われる。However, if the amount of rainfall increases significantly due to heavy rain etc., the water level reaches b, and the float 10 is submerged, the moment due to the buoyancy of the float 10 around the mounting pin 8 becomes larger than the moment due to the weight of the lid 11. The float 10 moves (shown by an imaginary line in the figure), and as a result, the rainwater control valve 7 closes, the discharge from the discharge pipe 5 stops, and the rainwater is transmitted from the rainwater transmission pipe 6 into the rainwater storage infiltration tank 2. be exposed.
そして、雨水調節枡１内の水位がａまで下がると、今度
は取付ピン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１０の浮力によるモーメントより
大きくなる為、再び蓋工１が開き、放流管５からの放流
のみが始まる。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 pin 8 becomes larger than the moment due to the buoyancy of the float 10, so the lid 1 opens again. , only the discharge from the discharge pipe 5 starts.
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.
〔発明の効果〕
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
。[Effects of the Invention] 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.
