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
うになつている。 A rainwater inlet pipe 4 is connected to the upper end of the rainwater control cell 1, and rainwater collected in a rain gutter, a side gutter, etc. flows into the rainwater control cell 1 through the rainwater inlet pipe 4.
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
になつている。 The 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 the 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、底よりやや上がつた位置に接続され
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.
したがつて、土砂や浮遊物は底に推積し、雨水
と共に放流されることはない。 Therefore, sediment and suspended matter accumulate on the bottom and are not discharged with rainwater.
また、底に推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 floating objects 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。 A rainwater discharge adjustment opening/closing valve 7 is attached to the entrance portion A of the rainwater discharge pipe 5.
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１０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 10 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
やや下がつた位置に接続され、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つている。 The rainwater supply pipe 6 is connected to a position slightly lower than the spout of the rainwater intake pipe 4, and the rainwater supply pipe 6
The rainwater in the rainwater control tank 1 is transferred to the rainwater storage infiltration tank 2.
Water is being supplied to the area.
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つている。 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の層を通つて地盤中
に徐々に浸透するようになつている。 A plurality of infiltration grooves 12,... are formed in a vertically striped lattice shape on the side of the rainwater storage infiltration tank 2, and the rainwater poured into the rainwater storage infiltration tank 2 from the infiltration grooves 12,... is transferred to surrounding crushed stones. It gradually penetrates into the ground through the layers of gravel to gravel 3.
このような構成に於いて、雨水調節枡１内への
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 such a configuration, until the water level in the rainwater control tank 1 reaches a, the rainwater discharge control valve 7 is closed.
remains open due to its own weight.
したがつて、雨水送水管６から雨水貯留浸透槽
２内の送水はなく、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１０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（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, when the amount of rainfall increases significantly due to heavy rain, etc., and 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 own weight of the lid 11. The float 10 moves (indicated by an imaginary line in the figure), and the rainwater control valve 7 closes accordingly.
The discharge from the discharge pipe 5 is stopped, and rainwater is transmitted from the rainwater transmission pipe 6 into the rainwater storage infiltration tank 2.
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１１
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 greater than the moment due to the buoyancy of the float 10, so the lid 11
opens, and only the discharge from the discharge pipe 5 begins.
よつて、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、従来必要であつ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 that was previously 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.
