GROUNDWATER RECHARGING METHOD AND GROUNDWATER RECHARGING DEVICE
To provide a method for recharging groundwater that can be injected into the ground with an arbitrary water level difference.SOLUTION: A groundwater recharging method according to the present invention includes a pumping step of pumping groundwater W1 from a deep well 101, a pressure adjusting step of pressurizing or depressurizing the inside of a recharge well 102 for injecting groundwater W2 into an aquifer 201-2 in advance, a water injection step of injecting groundwater W2 into the recharge well 102. In the pressure adjusting step, the water level difference ΔWL between the natural water level WL1 of the aquifer 201-2 and the water level WL2 corresponding to the pressure in the recharge well 102 is maintained at a predetermined water level difference ΔWX.SELECTED DRAWING: Figure 1
【課題】任意の水位差で地盤中に注水可能な地下水のリチャージ方法を提供する。【解決手段】本発明に係る地下水のリチャージ方法は、ディープウェル１０１から地下水Ｗ１を揚水する揚水工程と、地下水Ｗ２を帯水層２０１－２内に注水するためのリチャージウェル１０２内を予め加圧又は減圧する圧力調整工程と、リチャージウェル１０２内に地下水Ｗ２を注水する注水工程と、を備える。圧力調整工程において、帯水層２０１－２の自然水位ＷＬ１とリチャージウェル１０２内の圧力に対応する水位ＷＬ２との水位差ΔＷＬを所定の水位差ΔＷＸに維持する。【選択図】図１
