Ecological restoration construction technology for surface mine slope

Abstract

The invention relates to the technical field of ecological restoration, in particular to a surface mine slope ecological restoration construction technology. The method comprises the following steps: S1, safety treatment; s2, reinforcement treatment is conducted, specifically, concrete is sprayed on the side slope to form a concrete layer, then carbon fibers loaded with glucolactone are laid on the concrete layer, and a slow release layer is formed; s3, matrix reconstruction: spraying a plant matrix on the slow release layer to form a matrix layer, wherein the plant matrix comprises sodium alginate and sodium silicate; s4, vegetation reconstruction; and S5, monitoring and maintaining. In the application, through comprehensive use of the concrete layer, the slow-release layer containing the glucolactone and the carbon fibers and the substrate layer containing the sodium alginate and the sodium silicate, the situation of slope loosening and cracking caused during safety treatment is effectively solved, the slope can be further protected, weathering and collapse of the slope are avoided, and the safety of the slope is improved. And meanwhile, the problem that the plant substrate layer is easy to fall off is solved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an ecological restoration construction technology for open-pit mine slopes. Background technique [0002] The mine open-pit stope is severely affected by mining activities, the topsoil is stripped, the surface shape is changed, the original surface loses its original characteristics, and there are still many extreme physical and chemical properties that are harmful to the environment. The main characteristics are: the topsoil layer is destroyed, The lack of soil moisture and the increase in the content of toxic substances, etc., therefore, are particularly important for the ecological restoration of open-pit mine slopes. The construction of slope ecological restoration projects in open-pit mines should adhere to the principles of overall planning, comprehensive management, and ordering and implementing policies. Systematic construction should minimize the disturban...

Problems solved by technology

Second, it sprays the light-duty mixed base material layer on the slope subsequently. Due to the addition of organic polymer binders in the light-duty mixed base material, it promotes the formation of soil particle aggregates, and larger particle aggregates are not easy to be sprayed into the above-mentioned anchor rods and edges. The loose cracks between the slopes can neither play a role in stabilizing the slope, but also cause the temperature at which the light mixed matrix itself is easy to fall off the slope

Third, the seed-anti-erosion integrated layer is subsequently sprayed on the light mixed base material layer. The light mixed base material layer and the seed-anti-erosion integrated layer are only connected together by physical action, and the seed-anti-erosion integrated layer is easy to fall off , resulting in poor plant growth
