Tailing pond seepage interception structure with seepage interception wall combined with dewatering well and building method of tailing pond seepage interception structure
The invention discloses a tailing pond seepage interception structure with seepage interception walls combined with dewatering wells and a building method of the tailing pond seepage interception structure. Comprising dewatering wells and a vertical seepage-stopping wall, the vertical seepage-stopping wall is arranged at the downstream position of the tailing pond, the multiple dewatering wells are arranged at the upstream position of the vertical seepage-stopping wall, the upper portion of the vertical seepage-stopping wall adopts a continuous wall, and the lower portion of the vertical seepage-stopping wall adopts curtain grouting. According to the invention, the plurality of dewatering wells are arranged on the vertical seepage interception wall, and after the underground runoff part of discharged wastewater is intercepted by the vertical seepage interception wall, polluted underground water is collected in time through the dewatering wells and flows back for reuse, so that the escaping seepage water of the tailing dam and the surrounding thereof is effectively collected, and the underground water level of the vertical seepage interception wall is reduced; and meanwhile, the durability of the vertical seepage interception wall structure can be greatly improved, the service life is prolonged, the engineering investment is small, the application range is wide, the later maintenance is simple, the maintenance cost is low, and the environmental protection benefit, the safety benefit and the economic benefit are extremely remarkable.
本发明公开了一种截渗墙联合降水井的尾矿库截渗结构及其修筑方法。包括降水井和垂直截渗墙，垂直截渗墙设置于尾矿库下游位置，多个降水井设置于垂直截渗墙的上游，垂直截渗墙的上部采用连续墙，垂直截渗墙的下部采用帷幕灌浆。本发明通过在垂直截渗墙上游设置多个降水井，外排废水的地下径流部分经垂直截渗墙截断后，通过降水井及时将受污染的地下水收集并回流回用，有效收集了尾矿坝及其周围的外逸渗水，降低垂直截渗墙的地下水水位，降低渗水坝肩绕渗或基底渗漏的风险，同时可大大提高垂直截渗墙结构自身的耐久性，提高使用寿命，且工程投资小，适应范围广，后期维护简单，维修成本较低，环保效益、安全效益和经济效益极为显著。
