PILE BUILT-IN PUMPING WELL, AND UNDERGROUND WATER PUMPING METHOD
To provide a pile built-in pumping well and an underground water pumping method capable of shortening a construction period by combining a pile hole and a hole of a pumping well and capable of discharging underground water while supporting a structure using a pile in a pumping well.SOLUTION: A casing pipe 7 is arranged in a ground 1. Next, inside the casing pipe 7, an H-shaped steel pile 5a, a pump 17 disposed between flanges of the H-shaped steel pile 5a, pumping piping 21 disposed between the flanges and connected with the pump 17, and a net 29 disposed so as to surround an outer periphery of the H-shaped steel pile 5a are integrally built. And, foot protection concrete 35 of the H-shaped steel pile 5a is installed, a water guide material 37 is used to fill the inside of the net 29a, and the casing pipe 7 is removed from the ground 1, to complete a pumping well 41. Then, underground water in the ground 1 is discharged from the pumping piping 21 by operating the pump 17 while supporting a structure using the H-shaped steel pile 5a.SELECTED DRAWING: Figure 5
【課題】杭孔と揚水井の孔とを併用することで工期短縮が可能であり、揚水井内の杭で構造物を支持しつつ地下水を排水することができる杭一体型の揚水井および地下水の揚水方法を提供すること。【解決手段】地盤１にケーシング管７を設置する。次に、ケーシング管７の内部に、Ｈ型鋼杭５ａと、Ｈ型鋼杭５ａのフランジ同士の間に配置されたポンプ１７と、フランジ同士の間に配置されてポンプ１７に接続された揚水配管２１と、Ｈ型鋼杭５ａの外周を囲むように配置された網２９とを一体として建て込む。そして、Ｈ型鋼杭５ａの根固めコンクリート３５を打設し、網２９の内側に導水材３７を充填し、ケーシング管７を地盤１から撤去して、揚水井４１を完成する。その後、Ｈ型鋼杭５ａで構造物を支持しつつ、ポンプ１７を作動させて揚水配管２１から地盤１の地下水を排水する。【選択図】図５
