Problems solved by technology

[0003] Karst is a unique landform phenomenon in areas where carbonate rocks are distributed. At present, the single vegetation slope protection methods for slopes include turf slope protection, vegetation belt slope protection, hydraulic spraying grass slope protection, three-dimensional vegetation net slope protection, vetiver grass hedge slope protection, etc. There are traditional guest soil spraying techniques, but the above methods cannot fundamentally solve the problems of karst mountain soil structure, soil compactness, hardness, and integrity. As a result, the higher and steeper the slope, the greater the cumulative pressure. The greater the lateral pressure on the slope protection, and with the rainfall, a large amount of water and soil loss, the destruction of vegetation, the easier it is to be damaged and slumped, which is extremely harmful

Abstract

The invention discloses an abrupt slope massif slope surface vegetation ecological protection construction method. The method includes the following steps that 1, intercepting ditches are formed in the slope surface of an abrupt slope massif, and a concave water discharge way is formed between the adjacent upper intercepting ditch and the lower intercepting ditch; 2, floating stones falling off easily on the abrupt slope massif slope surface are removed, the abrupt slope massif slope surface is wet with water after the stones are removed, ecological restoration vegetation substrates for reinforcing an abrupt slope is mixed with water to prepare slurry, and the slurry is sprayed on the abrupt slope massif slope surface; 3, anchor rods are fixed to the abrupt slope massif slope surface, then vegetation component cages are fixed onto the anchor rods, and a grid screen and a steel rope screen are sequentially arranged above vegetation components; 4, the slurry prepared by mixing the ecological restoration vegetation substrates for reinforcing the abrupt slope with the water is sprayed on the abrupt slope massif slope surface provided with the vegetation component cages, the grid screen and the steel rope screen. The method is easy and convenient to implement, the ecological restoration problem of high and steep exposed rock slope surfaces is solved effectively, hidden dangers of road traffic engineering are eliminated, and the construction project quality is guaranteed.

Description

technical field [0001] The invention belongs to the fields of ecological protection of vegetation on steep mountain slopes and road traffic engineering safety, and in particular relates to a construction method for ecological protection of vegetation on steep mountain slopes. Background technique [0002] Protecting the ecological environment and promoting the healthy and sustainable development of the social economy have become the consensus and common task of all countries in the world. In recent years, with the acceleration of the development of western China, more and more mountain excavations have occurred, causing serious ecological damage. The research and application of reasonable and effective vegetation slope protection engineering technology is an urgent need to rebuild our country's good ecological environment, build green passages, and ensure the smooth flow of traffic arteries. [0003] Karst is a unique landform phenomenon in areas where carbonate rocks are d...
