A method of filling a deep cyclone pool with air lift to drain seepage and build a dam

Abstract

The invention discloses a method for building a dam by filling a deep layer of a swirl pool with air lift and seepage drainage. The steps include: digging a drainage ditch on the dam body, embedding a drain pipe, an air intake pipe, and an air lift drain pipe, and the outlet of the drain pipe provided with a drain valve Connect to the drainage ditch; build two small dams on the top of the dam; install air lift and seepage drainage devices in the two small dams, and communicate with the air intake pipe and air lift drainage pipe; Connected slotted seepage drainage board; discharge the rough tailings into the ditch pool; open the drain valve to start the seepage drainage device, and the thick tailings in the pool will be drained and solidified; put ore into the tailings pond to form a slope beach; Slotted seepage drainage boards are laid on the surface to the inside of the reservoir; a water diversion system with a water diversion valve is installed under the seepage diversion board; a slope beach surface is formed inside the dry beach; after the ore drawing is completed, the diversion valve is opened to discharge the water and the tailings are consolidated , adopting this method at the top of the dam can continue to construct the dam rapidly. The invention improves the stability and anti-slip capability of the dam body, effectively improves the strength of the dam body and the dry beach, and has low construction cost.

Description

technical field [0001] The invention is applied to a tailing reservoir dam construction and reinforcement method for high water content and solid waste stockpiling and dam construction, and specifically refers to a method for dam construction by filling deep layers of swirl pools with air lift and seepage drainage. Background technique [0002] Most of the mine tailings are transported by pipeline, and the tailings reservoir adopts upstream dam construction, and most of them use swirl bagging to build sub-dams or foreign materials to build sub-dams. When constructing sub-dams, the foundation of sub-dams is located on the dry beach, and the bottom If the infiltration line is too high and the strength is weak, the internal deformation of the dry beach will be caused by the extrusion of foreign materials used in the swirl bagging dam and the reinforcement foundation, and the overall stability of the tailings pond will be out of balance, which will easily cause deformation and da...

Problems solved by technology

[0002] Most of the mine tailings are transported by pipeline, and the tailings reservoir adopts upstream dam construction, and most of them use swirl bagging to build sub-dams or external materials to build sub-dams. If the infiltration line is too high and the strength is weak, the internal deformation of the dry beach will be caused by the extrusion of foreign materials used in the swirl bagging dam and the reinforcement foundation, and the overall stability of the tailings pond will be out of balance, which will easily cause deformation and dam failure

The dry beach of the pile body is slowly consolidated, and foreign materials need to be used to strengthen the foundation. The cost of dam construction is high, the waste of resources is large, and the dam construction takes a long time
