Tailing dam seepage drainage system
The invention discloses a tailing dam seepage drainage system. The tailing dam seepage drainage system comprises a plurality of seepage drainage mechanisms, wherein each seepage drainage mechanism comprises a water pump, a water inlet of the water pump is connected with a plurality of seepage drainage main pipes, the seepage drainage main pipes are connected with a collection water storage tank, and the water storage tank is wrapped by plastic materials and concrete. A plurality of S-shaped seepage drainage pipes are embedded at the inclination angle of 30-50 degrees along the portion, with the low outer portion and the high inner portion, of the top of a preliminary dam, the seepage drainage pipes are wrapped by a first layer of geotechnical mat and a second layer of geotechnical cloth, and a 20-30cm inverted filter layer is additionally arranged on the outermost layer. The radiation area of the S-shaped seepage drainage pipes and the radiation area of the vertical seepage drainage pipes are far larger than that of a common seepage drainage device, the S-shaped seepage drainage pipes collect pore water in tailings and flow to the water storage tank, and the water storage tank canpump out the pore water through the water pump at regular intervals and can also flow out of the preliminary dam through the gravity effect to be drained to a dam abutment flood intercepting ditch. Aninstallation frame, a connecting pipe and a vacuum pump are arranged on the top of a tailing dam fill dam, the vacuum pump is started to enable the S-shaped seepage drainage pipes to generate negative pressure, meanwhile, positive pressure is generated through the self weight of the tailings, the pore water outflow speed is greatly increased, and seepage drainage is effectively carried out.
本发明公开了一种尾矿坝排渗系统，包括若干排渗机构，排渗机构包括水泵，水泵进水口连接若干排渗主管，所述排渗主管连接收集储水箱，所述储水箱由塑料材质和混凝土包裹。沿着初期坝顶部以外低里高30～50的倾斜角度预埋多段S型排渗管，所述排渗管外部先由第一层土工席垫，第二层层土工布包裹，最外层加一层20～30cm的反滤层。S型排渗管和竖直排渗管的辐射面积远远大于普通排渗装置，而且S型排渗管收集尾砂中孔隙水并流向储水箱，储水箱可以由水泵定期抽出孔隙水，也可以通过重力作用流出初期坝低排向坝肩截洪沟。在尾矿坝堆积坝顶部有安装框、连接管、真空泵，打开真空泵使S型排渗管产生负压，同时尾砂自重产生正压，大大增快孔隙水出流速度，并有效的进行排渗。
