Method for ecological restoration of high-altitude slope

Abstract

The invention discloses a method for ecological restoration of a high-altitude slope. The method comprises the steps that sundries on the surface of the high-altitude slope are cleared away, wherein the sundries comprise pumice stones and capping mass, and leveling is conducted to the slope surface; an anchor rod position is marked, drilling is conducted, the top of the anchor rod is bent, and an anchoring agent is poured for fixation; a reinforcement net is paved on the slope surface and fixed on the anchor rod reserved on the slope surface; and a plant fiber blanket is paved, a geo-grid is then paved, and watering and conservation are conducted after fixation. According to the invention, rubble falling and collapse on the slope surface can be prevented; the steadiness of the slope surface structure is ensured; the plant fiber blanket is paved on the slope surface; stability of the slope is enhanced; moisture evaporation on the slope surface can be effectively reduced; the plant growth density can be rationally controlled; and vegetation coverage can be ensured, and demands for nutrients can be reduced. The method disclosed by the invention is used for the ecological restoration of the high-altitude slope; construction technologies are simple; the level of management and maintenance is reduced; consumption of manpower and materials can be greatly reduced; construction cost is reduced; and restoration effects of an ecological system are good.

Description

technical field [0001] The invention relates to the technical field of slope restoration, in particular to a method for ecological restoration of high-altitude slopes. Background technique [0002] High altitude slopes are distributed all over my country. The common disease types of slopes are: weathering and spalling, flowing rocks and mud, falling rocks, collapse, topple, collapse, collapse, slide, slide, landslide, scattered and so on. Due to the large slope and high slope height, the slope itself has very low water retention, fertilizer retention and soil fixation capabilities, and it is difficult to restore vegetation on the slope, which not only takes a long period, but also has poor results. At present, the treatment measures for high-altitude slopes mainly include thick-layer base material greening method, foreign soil spraying, vegetation concrete slope protection and other methods. The self-weight makes the spraying layer unable to resist the rainstorm and the sc...

Problems solved by technology

Due to the relatively large slope and high slope height, the ability of the slope to retain water, fertilizer and soil is very low, and it is difficult to restore vegetation on the slope, which not only takes a long period, but also has poor results.

At present, the treatment measures for high-altitude slopes mainly include thick-layer base material greening method, foreign soil spraying, vegetation concrete slope protection and other methods. The self-weight makes the spraying layer unable to resist the rainstorm and the scorching sun, eventually causing gully erosion, sheet erosion, and even the overall collapse of the slope, which not only fails to solve the fundamental problem of soil consolidation, but causes secondary slope damage; The relationship between vegetation and natural soil and rocks is isolated, and it is restricted by slope angle and slope height, resulting in a series of problems such as low seed germination rate, small vegetation coverage, and unstable and prone to lodging of plant roots.
