Refuse landfill deep precipitation pump drainage vertical well construction method
The invention discloses a refuse landfill deep precipitation pump drainage vertical well construction method, and relates to the technical field of precipitation and drainage. The refuse landfill deepprecipitation pump drainage vertical well construction method includes the following steps that a, a drill hole is drilled in the ground; b, a reinforcement cage is wrapped by a two-way geogrid, andthen the reinforcement cage is put in the drill hole; c, the outer side of a galvanized steel pipe is wrapped by a geo composite drainage network, then the galvanized steel pipe is put in the drill hole, and the galvanized steel pipe is located in the reinforcement cage; d, the position between the reinforcement cage and the galvanized steel pipe is filled with gravel through a gravel filling machine; and e, a submerged pump for pumping leachate is mounted in the galvanized steel pipe. Blockage can be avoided, and meanwhile by means of a hopper, the gravel is prevented from entering the galvanized steel pipe.
本发明公开了一种垃圾填埋场深层降水抽排竖井施工方法，涉及降排水技术领域；一种垃圾填埋场深层降水抽排竖井施工方法，步骤如下：步骤a：在地面上钻出钻孔；步骤b：在钢筋笼外包裹双向土工格栅，然后将钢筋笼放入钻孔内；步骤c：在镀锌钢管外侧包裹土工复合排水网，然后将镀锌钢管放入钻孔，镀锌钢管位于钢筋笼内；步骤d：利用灌石机在钢筋笼和镀锌钢管之间灌注碎石；步骤e：在镀锌钢管内安装用于抽取渗沥液的潜水泵。本发明可以避免堵塞，同时料斗的使用防止碎石进入镀锌钢管。
