Tailing pond environment-friendly seepage interception structure based on dewatering well group and building method thereof
The tailing pond environment-friendly seepage interception structure comprises a precipitation well seepage interception layer formed by arranging a plurality of precipitation wells, the precipitation well seepage interception layer is arranged at the downstream position of a tailing pond, each precipitation well comprises a well wall, a peripheral inverted filter layer, a cover plate and water pumping equipment, and the upper portion of each well wall is of a waterproof structure; the lower portion of the well wall is of a permeable structure with water seepage holes, the peripheral inverted filter wraps the lower portion of the well wall, the cover plate is arranged at a well mouth, and the water pumping device is arranged inside. The precipitation well seepage interception layer is formed by arranging the multiple precipitation wells and serves as an environment-friendly seepage prevention structure of the tailing pond, the seepage interception effect is ideal, seepage sewage of the tailing dam body, the foundation and the bank slope mountain can be effectively collected, the construction speed is high, the engineering investment is small, the maintenance cost is low, and the application range is wide.
本发明公开了一种基于降水井群的尾矿库环保截渗结构及其修筑方法，包括由多个降水井排列组成的降水井截渗层，降水井截渗层设置于尾矿库下游位置，降水井包括井壁、外围反滤层、盖板和抽水设备，井壁的上部为不透水结构，下部为开设有渗水孔的透水结构，外围反滤层包裹井壁的下部，盖板设置于井口，抽水设备设置于内部。本发明通过设置多个降水井形成降水井截渗层，作为尾矿库环保防渗结构，截渗效果理想，可有效收集尾矿坝坝体、地基及岸坡山体渗漏污水，施工速度快，工程投资小，且维修成本较低，适用范围广。
