The anti-erosion effect of vegetation is achieved through its three main components: first, the growth layer of plants (including sepals, leaf sheaths, leaf blades, and stems), which prevents the surface soil of the slope from being directly eroded by rainwater through its dense coverage. When the plants grow lushly, they can resist runoff velocities up to 6m/s.
Twice as much for general turf. The presence of geotextile effectively reduces water evaporation from slope soil and increases infiltration. Additionally, due to the black absorbing properties of the geotextile material, it promotes seed germination and facilitates plant growth. Firstly, within a certain thickness range, it enhances the protective and mechanical stability properties. Secondly, the three-dimensional structure of the net connects with the extensive root systems of plants, forming a sheet structure (equivalent to reinforcing the surface soil of the slope), thereby increasing the tensile and shear strength of the protective layer and limiting the expansion of "gradual destruction" (erosion can directly damage individual plants, and over time, the damaged area increases).
Ultimately restricts the occurrence of shallow surface sliding and uplifting of slopes. The three-dimensional vegetation mesh slope protection technology combines the advantages of geotextile nets and vegetation slope protection, serving as a composite slope protection. When the vegetation coverage rate of the slope reaches over 30%, it can withstand the erosion from light rain; when the coverage rate is over 80%, it can withstand the erosion from heavy rain. In areas difficult to manage due to drought, soil condensers can be used. The selected suitable grass seeds, after special treatment, are mixed with the soil condenser and sprayed (it can also be sown with grass seeds first, followed by the application of the soil condenser). The slope surface treated with soil condensers ensures that grass seeds and soil will not be lost due to wind and rain, while the condenser also reduces the evaporation of soil moisture, to some extent ensuring the water supply to the grass seeds.
Significantly increase the survival rate of grass seeds. Reduce the erosive energy of heavy rain runoff and the speed of surface runoff, thereby reducing soil erosion; secondly, the humus layer (including the interface between the leaf litter layer and the root stem), provides a protective layer for the surface soil of the slope; thirdly, the root zone, which reinforces and anchors the surface soil of the slope, providing mechanical stability. Generally, in the early stages of plant growth, due to the loose intertwining of individual plant roots without a sprawling root system, they are prone to separate from the soil layer and fail to provide protection. The application of the three-dimensional mesh is precisely to enhance the effects of these three aspects to achieve more comprehensive shallow protection.
