（発明が解決しようとする問題点）
調節池の容量は流域面積、流出係数、許容放流
量と、降雨強度式より算出される。(Problems to be Solved by the Invention) The capacity of a regulating pond is calculated from the basin area, runoff coefficient, allowable discharge amount, and rainfall intensity formula.
降雨強度式は確率年により定まり、長年確率
（例えば５年）は、短年確率（例えば３年）より
流出量が大きくなる。 The rainfall intensity formula is determined by the probability year, and the amount of runoff is larger in the long-term probability (eg, 5 years) than in the short-term probability (eg, 3 years).
而して前記自然放流式調節池は広大な用地を必
要とし、用地費が嵩むという難点があり、また前

難点があり、更に長年確率降雨強度式で計算する
場合、前記両調節池とも問題があつた。 However, the natural discharge type regulation pond has the disadvantage of requiring a vast amount of land and the land cost is high, and the underground pump-up type regulation pond has the disadvantage of maintenance and management. When calculating, there were problems with both of the reservoirs.

題点を解決するものである。(Means for Solving the Problems) The present invention relates to a rainwater control pond proposed to solve the above-mentioned problems, and includes a natural discharge type rainwater control tank and an underground pump-up type rainwater control tank. The above-mentioned problem is solved by arranging them in two layers.

に返し、同槽の堰より越流させる。(Function) As described above, the rainwater regulation pond according to the present invention is formed into a two-stage rainwater regulation pond in which the upper stage is a natural discharge type rainwater regulation tank and the lower stage is an underground pump-up type rainwater regulation tank. Therefore, the short-term stochastic runoff is discharged through the upper natural discharge type rainwater control tank, and the difference between the long-term stochastic runoff and the short-year stochastic runoff is secured in the lower underground pump-up rainwater control tank. Then, after the water level in the upper natural rainwater control tank has decreased, the water is pumped up and returned to the natural rainwater control tank, where the water is allowed to overflow from the tank's weir.

ものである。(Effects of the Invention) In this way, in the present invention, by arranging the natural discharge type rainwater control tank and the underground pump-up type rainwater control tank in two layers, upper and lower, it is possible to achieve an improvement compared to a natural discharge type control pond. It requires less land and reduces pump equipment costs compared to underground pump-up type control ponds, making it an economical rainwater control pond.
（実施例） 以下本考案を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.
１は上段に配置された自然放流式雨水調節槽
で、その下段に地下式ポンプアツプ方式調節槽２
が配設され、前記上段の自然放流式雨水調節池１
は短年確率流出量を自然放流し、長年確率流出量
と短年確率流出量との差分を前記下段の地下式ポ
ンプアツプ方式雨水調節槽２で確保し、ポンプア
ツプするものである。 1 is a natural discharge rainwater control tank located on the upper level, and an underground pump-up type control tank 2 is located on the lower level.
is arranged, and the upper natural discharge type rainwater control pond 1
The short-year stochastic runoff is naturally released, and the difference between the long-term stochastic runoff and the short-year stochastic runoff is secured and pumped up in the underground pump-up type rainwater control tank 2 in the lower stage.
今、設計確率年（例えば５年）の調節容量を
V5とし、短年確率年（例えば３年）の調節容量
をV3とすると、上段の自然放流式雨水調節池１
でV3を確保して自然放流し、下段の地下式ポン
プアツプ方式雨水調節槽２で（V5−V3）の容量

してからポンプ３を作動して前記雨水調節池１に
戻し、（V5−V3）の水量は同雨水調節池１の堰よ
り越流させ、放流河川４に流す。 Now, the adjustment capacity for the design probability year (for example, 5 years) is
If V 5 and the regulation capacity for a short return period (for example, 3 years) are V 3 , then the upper natural discharge rainwater regulation pond 1
Ensure V 3 and allow natural discharge, secure the capacity of (V 5 - V 3 ) in the underground pump-up rainwater control tank 2 at the bottom, and start pumping after the water level of the natural discharge rainwater control tank 1 has decreased. 3 is activated to return the rainwater to the rainwater regulating pond 1, and the amount of water (V 5 - V 3 ) is allowed to overflow from the weir of the rainwater regulating pond 1 and flow into the discharge river 4.
このように図示の実施例によれば、自然放流式
