Introduction of Vegetation Concrete Slope Greening Technology
Adopting specific concrete formula and mixed planting green seeds formula is a new technology for rock slope protection and greening. The core of this technology is the extensive application of cement to enhance the strength and erosion resistance of slope protection and quickly create an environment for plant growth. Ecological protection technology of vegetation concrete can not only solve the problems of rock slope protection and rapid greening, but also further enhance the anti-erosion ability of substrate under the joint action of grass-irrigated vegetation and substrate. Ensure the rapid formation of vegetation and ecological stability. Ordinary net-hanging soil spraying or hydraulic spraying can not achieve permanent stability on high-steep rock slopes, but vegetation concrete technology is a new technology for ecological protection of high-steep rock slopes (concrete slopes and hard rock slopes) above 60 degrees [1999, patent of Three Gorges University, Xu Wennian, Liu] 1. This technology uses cement as adhesive and special additive. This technology has a high degree of mechanization, large production capacity, long spraying distance with dry shotcrete anchor machine, certain strength of sprayed layer and strong anti-scouring ability, and is especially suitable for steep rock slopes. 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 special additives is to create a growing environment for plants (patented invention of Three Gorges University, Xu Wennian, Liu et al. ); According to the biological growth characteristics, the formula of mixed sowing green seeds was optimized. Seeds are usually irrigated with tall fescue, ryegrass, bermudagrass, Lespedeza, Robinia pseudoacacia, Amorpha fruticosa and Magnolia multiflora.
