Embodiment Construction

[0031] A large-scale tailings reservoir structure with seepage and drainage type anti-sewage resource regeneration

[0032] Such as figure 1 The structural layer of the slope and the bottom of the large tailings reservoir area shown is provided with a base layer 1, a waterproof board layer 2, a seepage drainage pipe layer 3 and a geotextile layer 4 from bottom to top;

[0033] The base layer 1 is a flat and compacted base layer, and the edge is provided with a pressure groove 5 for trimming the top section of the slope, and a plain concrete pressure roof 6 is arranged above the pressure groove 5 .

[0034] The waterproof board layer 2 is a waterproof high-density polyethylene board with a thickness of 2.0mm arranged on the slope of the reservoir area and the base layer 1 at the bottom. , The overlap between the waterproof board and the board is at least 5cm in width, and the inflation test is adopted, and the quality is qualified if there is no air leakage.

[0035] The seep...

Abstract

The present invention is structure for preventing tail ore from polluting water resource. The structure includes base layer, waterproof board layer, water permeating and draining pipe layer and earth work fabric layer set from bottom to up. The base layer rolling grooves and concrete layer; the waterproof board layer is made of high density polyethylene plate; the water permeating and draining pipe layer has antirust spring water permeating and draining pipe, crushed stone stuffing, surface cement mortar layer, and extruded plastic board in the vertical surface; and the earth work fabric layer has overlapped earth work fabric. The present invention can prevent harmful chemical matter, heavy elements and water from tail ore to pollute underground water, river and soil in the peripheral area.

Description

technical field [0001] The invention relates to the anti-fouling technology of water resources, in particular to a tailings reservoir area structure of seepage and drainage type anti-sewage resource regeneration. Background technique [0002] Hazards from tailings waste. According to statistics, the total amount of industrial solid waste discharged by the global mining industry every year is tens of billions of tons. In my country, the waste rock tailings discharged by ferrous metal mines are about 620 million tons every year, and the waste rock tailings discharged by non-ferrous metal mines reach 115 million tons every year. , about 130 million tons of coal gangue. The large amount of random discharge of waste rocks and tailings from these mines and the unreasonable layout of the accumulation dam site have seriously damaged the natural ecological environment of land resources. Radioactive substances seriously pollute mining areas and surrounding groundwater, rivers, and fa...
