FINE BUBBLE WATER DISPLACEMENT METHOD, AND FINE BUBBLE WATER DISPLACEMENT DEVICE
To provide a displacement method and a displacement device which efficiently displace ground water to fine bubble water.SOLUTION: A fine bubble water displacement method includes: a pumping step of pumping up ground water using a pumping well 1; and a fine bubble water injection step of injecting fine bubble water BW from a water injection pipe 2, in which in the pumping step, the pumping well 1 is used which has a vertical hole 11, a well pipe 12 having a ground water inflow hole on its peripheral wall, a strainer 121 annularly installed in the well pipe 12, a lid member blocking an upper opening of the well pipe, a filter material 14 embedding a gap between the vertical hole 11 and the strainer 121, a vacuum pump 15 reducing the pressure inside the well pipe 12, and a pumping pump 16 pumping the ground water taken into the inside of the well pipe 12, and has the ground water inflow hole provided at a lower position of the uppermost end of a water passing part of the strainer 121.SELECTED DRAWING: Figure 1
【課題】地下水を効率よくファインバブル水に置換する置換工法並びに置換装置を提供する。【解決手段】ファインバブル水置換工法は、揚水井１を用いて地下水を揚水する揚水工程と、注水管２からファインバブル水ＢＷを注水するファインバブル水注入工程とを備え、揚水工程において、竪穴１１と、周壁に地下水流入孔を有する井戸管１２と、井戸管１２に環装されるストレーナ１２１と、井戸管の上部開口を閉塞する蓋部材と、竪穴１１とストレーナ１２１の隙間を埋めるフィルタ材１４と、井戸管１２の内部を減圧する真空ポンプ１５と、井戸管１２内部に取り込まれた地下水を揚水する揚水ポンプ１６とを有し、地下水流入孔が、ストレーナ１２１の通水部の最上端より下方位置に設けられた揚水井１を用いる。【選択図】図１
