Problems solved by technology

[0006] The defects of the above-mentioned flexible drainage channels are firstly that the resistance is large, the drainage is slow, and a large amount of sediment is easy to deposit in the channel, causing the drainage system to be paralyzed quickly; as a result of:
[0008] 2. A large amount of rainwater directly rushes to the slope and the horseway, causing soil erosion and even destroying the vegetation on the slope
[0009] 3. Rainwater infiltrates into the gangue area, producing leachate, polluting groundwater and soil
[0010] 4. The soil on the horse track is soaked for a long time, which can easily cause landslides, subsidence and subsidence, and then cause greater damage to the dr

Abstract

The invention designs a half-flexible quick drainage system applied to gangue dump treatment and aims to overcome the defect that gangue dump drainage channels are nonresistant to settling, prone to sedimentation and slow in drainage. Half-flexible drainage channels are adopted, so that damage to the channels caused by settling of gangue dump can be resisted, and quick drainage can be realized; various optimized design modes are adopted for the drainage system, each transverse drainage channel is designed with a U-shaped section, a higher middle, lower two sides and an adverse slope, so that more rainwater can enter the transverse drainage channels more quickly and can be discharged from a longitudinal drainage channel outside a gangue dump site more quickly, the problem of sedimentation in the drainage channels is solved effectively, and soaking of slopes and packways by the rainwater is reduced; the drainage channels have the advantages of high strength, corrosion resistance, long service life, freezing resistance and convenience for mounting and replacing, and a powerful guarantee is provided for long-time use of the drainage channels.

Description

Technical field [0001] The invention belongs to the technical field of drainage, and specifically relates to a semi-flexible rapid drainage system applied to the treatment of waste rock. Background technique [0002] Coal gangue is the largest industrial solid waste discharged by coal mines, accounting for about 10-20% of raw coal output. At present, there are thousands of gangue hills in the country that have not been treated, and hundreds of millions of tons of gangue are added every year. The gangue hill not only occupies a large amount of land and destroys the surrounding ecological landscape, but also releases a large amount of toxic and harmful gases and dust into the atmosphere, and produces a large amount of leaching solution. Therefore, the responsibility for the ecological environment management of the gangue hill is heavy and the task is arduous. [0003] The conventional method for the treatment of gangue hills: cutting slopes and finishing → covering soil → construct...
