Problems solved by technology

The ecological environment is the basis for the sustainable development of human society and economy, and a good ecology is one of the necessary conditions for human survival and life. Mining has exposed the surface of the mountain, which has seriously affected the ecological environment, resulting in varying degrees of damage to the ecological system. It restricts the sustainable development of human society and economy, and even endangers the safety of human beings. Therefore, ecological restoration has become the basic premise of mining. At present, the bare mountain body after mining mainly adopts artificial planting of trees to restore vegetation, but it takes a long time. And it is easy to cause soil erosion due to rainwater erosion

Abstract

The invention relates to a material for slope fixing and virescence and application thereof. The slope fixing and virescence material comprises a skeleton material, a pouring material and a virescence material, wherein the skeleton material is paved at the engineering part to be constructed, the pouring material is used for pouring after condensation, and maintenance is performed to form the slope fixing material; and the virescence material is paved on the surface of the slope fixing material and watering maintenance is performed until the plant root system penetrates the slope fixing material. The slope protecting and fixing materials with certain mechanical strength are combined with the phase with a network structure through scientific and reasonable constitution and proportioning, so that the side slope can be maintained, the plant root system can grow and develop in the slope fixing material, virescence is realized, and ecological restoration is promoted. The slope fixing and virescence material has the characteristics of good slope fixing and protecting effects, and can be widely applied to slope fixing and virescence of water edge, a road and a railway roadbed as well as ecological restoration of bare rock on two sides of the road and the railway and abandoned mines.

Description

technical field [0001] The invention belongs to the field of material science and engineering, and specifically relates to a material for slope consolidation and greening and its application. Background technique [0002] Slope protection refers to the general term for various paving and planting on the slope to prevent the slope from being scoured, including embankment reinforcement for flood protection, grid slope protection, and mountain ecological restoration. [0003] First of all, embankment reinforcement and flood control have always been an important task in our country every year. With the development of the national economy and the improvement of people's environmental requirements, the ecological construction of dikes and dams has increasingly become the consensus of people. At present, there are several ways to consolidate the slope of the waterfront. 1. Stone masonry or pouring concrete slabs. This method has no greening function, and the integrity of stone maso...
