Description

Drainage structures is held to refuse dump side slope

Technical Field

The utility model relates to a refuse dump side slope maintenance field especially relates to refuse dump side slope holds drainage structures.

Background

The refuse dump is also called a waste rock dump, and refers to a place for intensively discharging mine mining wastes. The refuse of the dump generally includes rotten surface soil, weathered rock and soil, hard rock and mixed rock and sometimes includes possible recycled surface ores, lean ores and the like.

The dump is a loose pile and has serious safety problems. The instability of the dump will cause mine dump disasters and major engineering accidents, which not only affect the normal production of the mine, but also cause the mine to suffer huge economic losses.

The surface soil reclamation of the refuse dump is a more scientific, economic and common green covering mode, and the refuse dump can be stabilized after green covering, so that safety accidents caused by instability are avoided, and water and soil resources can be utilized. The existing green covering mode adopted for the waste dump is simpler, trees and grass are planted after soil is covered, and reasonable soil conservation and water storage measures are not adopted in the structure and construction of a soil and rock heap. The plants planted after soil covering need a certain time for growing, and the existing green covering method mainly has the following problems in rainy seasons before the planted plants do not fully exert the water and soil conservation effect:

firstly, the soil nutrients and water in the waste dump can be greatly lost due to rain wash, and the soil with nutrients and water lost can not be required by the growth of the planted plants;

secondly, due to rain wash, a large amount of rain water flows down along with the side slope to generate gullies, the density of the erosion gullies is increased along with rainfall, the length and the depth of the erosion gullies are increased, the water and soil loss is increased along with the increase of the number and the length and the depth of the erosion gullies, the coverage rate of forest and grass is reduced year by year, the soil discharge field is more prone to instability, and the water and soil loss is serious;

thirdly, the soil washed by the rainwater flows to the ground outside the refuse dump from the toe of the slope and is accumulated on the ground, so that the side slope is expanded, the floor area of the refuse dump is increased, and the surrounding environment is damaged again;

fourthly, the plants do not root or root firmly, and due to the existence of water erosion, the surface soil and seeds are easy to flush downwards, so that the side slope of the waste dump is not uniformly greened, the seeds under the slope are more, the surface soil is thicker, and the coverage after greening under the slope is large; the superficial soil on the slope is thin and barren, the number of seeds is small, and the phenomenon of alopecia areata after greening is more.
