GROUND WATER LEVEL LOWERING METHOD
To reduce the number of necessary pumping wells without drilling the pumping well deeper.SOLUTION: A ground water level lowering method is the ground water level lowering method to lower water level h of the ground 10 by pumping ground water from the pumping well 20 formed in the ground 10, comprising a step forming in the ground 10 a water passage 32 extending in a side direction of the pumping well 20 and a step pumping the ground water from the pumping well 20 as introducing the ground water to the pumping well 20 through the water passage 32.SELECTED DRAWING: Figure 5
【課題】本発明は、揚水井戸の深さを深くせずに、揚水井戸の必要本数を低減することを目的とする。【解決手段】地下水位低下工法は、地盤１０に形成された揚水井戸２０から地下水を揚水し、地盤１０の地下水位ｈを低下させる地下水位低下工法であって、揚水井戸２０から側方へ延びる水みち３２を地盤１０に形成し、水みち３２を介して揚水井戸２０に地下水を引き込みながら、揚水井戸２０から地下水を揚水する。【選択図】図５
