METHOD FOR LOWERING GROUNDWATER LEVEL, METHOD FOR CONSTRUCTING DRAIN CHANNEL OF GROUND WATER AND STRUCTURE OF DRAIN CHANNEL OF GROUNDWATER
PROBLEM TO BE SOLVED: To provide a method for lowering a groundwater level to allow the groundwater level to be effectively lowered.SOLUTION: A method for lowering a groundwater level of the present invention is configured by arranging porous materials on a bottom wall and side walls of a drain channel of groundwater to lower the groundwater level by allowing the groundwater to pass through the bottom wall and side walls by penetrating and to be drained to the drain channel of the groundwater. Preferably, the drain channel of the groundwater is formed in a way that the side walls are tilted expanding a width of the channel in an upward direction to drain groundwater into the drain channel of the groundwater through the bottom wall and the side walls by upwardly penetrating. Preferably, the groundwater drained in the drain channel of the groundwater is forced to drain from the drain channel of the groundwater by a drainage pump.SELECTED DRAWING: Figure 1
【課題】本発明は、地下水位を効果的に低下させることができる地下水位低下方法を提供することを目的とする。【解決手段】本発明の地下水位低下方法は、地下水排水路の底壁及び側壁に多孔質体を配置した構成であり、地下水を前記底壁及び側壁の中を浸透の形で通過させて前記地下水排水路に排水することで地下水位を低下させる方法である。前記地下水排水路は、流路幅が上部へ向けて広がるように前記側壁が傾斜して形成され、地下水を前記底壁及び側壁の中を上向き浸透の形で通過させて前記地下水排水路に排水することが好ましい。前記地下水排水路に排水された地下水を、前記地下水排水路から排水ポンプにより強制的に排水することが好ましい。【選択図】図1
