Dewatering well construction method, dewatering well and dewatering well system
The invention provides a precipitation well construction method, a precipitation well and a precipitation well system. The method comprises the steps that drilling and punching of a first preset hole diameter are carried out at a preset position, and a drilled hole is obtained; when the depth of the drill hole reaches the position of the top plate of the aquifer, clear water is added into the drill hole for slurry making, and first slurry is formed in the current drill hole so as to support the hole wall of the current drill hole; when the depth of the drilled hole reaches the preset depth, the current drilled hole is expanded, a formed hole is obtained, the expanded hole depth is the preset well depth, the preset well depth is larger than 100 m, the expanded hole diameter is the second preset hole diameter, and the second preset hole diameter is larger than the first preset hole diameter; and a sand setting pipe and a water filtering pipe are installed in the formed hole, the outer wall of the water filtering pipe, the outer wall of the sand setting pipe and the hole wall of the formed hole are filled with filter materials, a water pump and a water pumping pipe are installed in the water filtering pipe, and the dewatering well is obtained. According to the invention, a good dewatering effect can be maintained when the depth of the dewatering well exceeds 100 meters.
本发明提供一种降水井施工方法、降水井及降水井系统。该方法包括：在预设位置进行第一预设孔径的钻进打孔，得到钻孔；当钻孔的深度至含水层顶板位置时，向钻孔内加入清水进行造浆，在当前钻孔内形成第一泥浆，以便支撑当前钻孔的孔壁；当钻孔的深度达到预设深度后，对当前钻孔进行扩孔，得到成孔，扩孔的深度为预设井深，预设井深大于100m，扩孔的孔径为第二预设孔径，第二预设孔径大于第一预设孔径；在成孔的内部安装沉砂管和滤水管，在滤水管的外壁、沉砂管的外壁和成孔的孔壁之间填充滤料，在滤水管的内部安装水泵和抽水管，得到降水井。本发明能够在降水井的深度超过100米时保持良好的降水效果。
