WATER POURING WELL AND GROUND WATER RECHARGE DEVICE
To provide a water pouring well which can be easily manufactured while enhancing a cleaning effect.SOLUTION: A recharge well (water pouring well) 150 includes: a cylindrical well body 151 which extends in a vertical direction; a cylindrical screen 152 which is connected to a lower end of the well body 151 and extends in a vertical direction; and a filter 154 which is brought into contact with the screen 152 and is provided outside in a radial direction of the screen 152. The screen 152 is formed with a plurality of through holes 161. The filter 154 is composed of a plurality of filter particles 551 having an approximately single central particle diameter. The central particle diameter of the plurality of filter particles 551 is larger than the maximum dimension of the through holes 161.SELECTED DRAWING: Figure 1
【課題】洗浄効果を高めつつ容易に製造可能な注水井戸を提供する。【解決手段】リチャージウェル（注水井戸）１５０は、鉛直方向に延びる筒状の井戸本体１５１と、井戸本体１５１の下端に接続されて鉛直方向に延びる筒状のスクリーン１５２と、スクリーン１５２に接してスクリーン１５２よりも径方向外側に設けられたフィルター１５４と、を備える。スクリーン１５２には、複数の貫通孔１６１が形成されている。フィルター１５４は、略単一の中央粒径を有する複数のフィルター粒子５５１で構成されている。複数のフィルター粒子５５１の中央粒径は、貫通孔１６１の最大寸法よりも大きい。【選択図】図１
