Zhong Da Consulting collated the basic situation of slope greening treatment through the knowledge of architectural knowledge column of this website. The main contents are as follows:
Slope greening is a new ecological slope protection method, which can effectively protect the exposed slope. Combined with traditional civil engineering slope protection (reinforced anchor support, hanging net, lattice, etc.), the restoration and protection of slope ecological vegetation can be effectively realized. ).
Slope greening treatment content:
The environmental protection significance of slope greening is very obvious. Slope greening can beautify the environment, conserve water, prevent soil erosion and landslides, and purify the air. For rocky slopes, the environmental protection significance of slope greening is particularly prominent.
Vegetation concrete slope protection and greening engineering technology
Vegetation concrete slope protection and greening engineering technology is a new technology for protecting and greening rock slopes by using specific concrete formula and seed formula. The concrete methods of vegetation concrete slope protection and greening engineering technology are as follows:
First, lay barbed wire or plastic net on the rock mass and fix it with anchor nails and anchor rods. After the raw materials of vegetation concrete are mixed, they are sprayed on the rock slope with conventional anchor and shotcrete equipment to form vegetation concrete with a thickness of nearly 10cm. After spraying, it is covered with a layer of non-woven fabric, which is sunscreen and moisturizing. Cement makes the vegetation concrete form a protective layer with a certain strength. After a period of water conservation, the grass will cover the slope, remove the non-woven fabric, and the dense grass will grow naturally. Vegetation concrete slope protection greening engineering technology can solve the problem of rock slope protection greening once and for all.
Vegetation concrete consists of cement, soil, humus, long-acting fertilizer, water-retaining agent, special additives and mixed green seeds. Cement is a kind of consolidated material with strength to achieve the purpose of engineering protection, and 425# cement is generally used; Soil is the basic substance for plants to provide nutrients and store nutrients for a long time, and loam or sandy loam (sand content is less than 5%) is generally used; Humus is the basic substance that gives priority to providing nutrients for plants and creating space for plant root growth. Generally, distiller's grains, sawdust and straw fiber are used. Long-acting fertilizer is a long-acting compound fertilizer for plant growth; Water-retaining agent absorbs water when the water is sufficient and provides water for plants when the weather is dry. Generally, water-retaining agent with particle size of 100 mesh is used. The main function of additives is to create a plant growth environment (patent of Three Gorges University, Liu); The mixture is preferably prepared according to biological growth characteristics. Generally, water-saving grass, ryegrass, Bermuda grass, Leymus chinensis, white clover, Robinia pseudoacacia, Leucaena leucocephala and Magnolia multiflora are used.
