A high-efficiency vertical seepage drainage device for tailings pond

Abstract

The invention discloses a high-efficiency vertical seepage drainage device for a tailings pond, which comprises a seepage drainage pipe (1) and a connecting pipe (2). The seepage drainage pipe (1) is vertically arranged in the tailings pond and passes through the connecting pipe (2) Connected with the hidden drainage pipe and the drainage chute of the tailings pond or directly lead out of the pond, the seepage drainage pipe (1) consists of a pipe body (3) with a plurality of through holes (31) in the center, and a covering pipe The filter cloth (4) and the fixed net (5) on the outer circumference of the body (3) constitute. The present invention vertically arranges seepage drainage pipes with through-holes on the inner wall and outer covering filter cloths in the tailings dam, so that the tailings are funnel-shaped to discharge seepage at about 45° along the drainage pipes, and the seepage drainage area increases with the accumulation of tailings. Gradually increase, the closer to the seepage pipe, the better the effect, so as to effectively reduce the infiltration line in the vertical direction and ensure the safety of the tailings pond. Compared with the traditional horizontal seepage discharge pipe, the seepage discharge pipe of the present invention is more resistant to pressure and less prone to bending, and can also be used as a horizontal seepage discharge pipe, and can also be used in combination with the horizontal seepage discharge pipe.

Description

technical field [0001] The invention belongs to the technical field of mine engineering, and in particular relates to a high-efficiency vertical seepage discharge device for a tailings pond with stable and reliable operation, high seepage discharge efficiency and low operating cost. Background technique [0002] The dam body of the initial dam of the tailings reservoir in our country is made of earth and rocks with varying degrees of water permeability. The stacking method of the tailings reservoir dam mostly adopts the upstream stacking type. Since this type mainly drains the seepage water immersed in the reservoir through the tailings filter structure formed by accumulation, once the filter structure is difficult due to some reasons (such as too many interlayers of fine-grained sediment in the reservoir, etc.) If it is formed or destroyed, the seepage line inside the reservoir will rise, and seepage water may escape from the dam slope to form a swamp on the dam surface, a...

AI Technical Summary

Problems solved by technology

Generally, a set of horizontal seepage drainage devices is installed when the tailings dam is about 4 meters away. This device cannot drain the water below the seepage drainage pipe, and only a small part of the water that is too high above the seepage drainage device can be discharged into the pipe. Its scope is limited

Moreover, traditional horizontal seepage drainage pipes are easy to bend and not resistant to compression, so they can only be arranged horizontally
