Characteristics of geotechnical three-dimensional vegetation net: 1. Due to the role of net bag, it can reduce the impact energy of raindrops, and block the flow rate of rainwater on the slope through net bag, thus effectively resisting the characteristics of rainwater scouring geotechnical three-dimensional vegetation net:
1. Due to the role of the net bag, the impact energy of the raindrop can be reduced, and the flow rate of the rainwater on the slope is blocked by the net bag, thereby effectively resisting the scouring of the rainwater.
2. The fillings (soil particles, nutrient soil and grass seeds, etc.) in the net bag can be well fixed, so that the loss will be reduced under the action of rainwater erosion.
3. It acts as a reinforcing reinforcement in the surface soil of the slope, thus effectively preventing the slip of the surface soil layer.
4, three-dimensional vegetation network can contribute to the uniform growth of vegetation, the roots of vegetation can easily grow and fix in the slope soil layer.
5. The three-dimensional vegetation net can be made into a grass blanket for transplanting in different places, which can solve the vegetation requirements for rapid protection engineering.
Geotechnical 3D Vegetation Net Specifications:
Polymer: Polyethylene Thickness: 12mm
Unit weight: 0.43kg/m2
Unit pull: 3.2kn/m
Three-dimensional vegetation net size: 50m*2m
Three-dimensional vegetation network rapid protection measures work:
1. The three-dimensional vegetation net has a contradiction between the construction period and the vegetation cultivation period. When the project just enters the rainstorm season, the HDPE geomembrane needs to adopt the “reinforced turf†to quickly protect the project, so that it can be fully covered after completion. Scour the vegetation. “Reinforced turf†uses a three-dimensional vegetation net to pre-plant the turf on the turf plantation or in the open space near the construction site. After the ping, it can be rolled up or rolled up and then laid on the slope to be protected.
2. Three-dimensional vegetation network In the arid areas that are difficult to control, soil coagulant can be used to mix the selected grass seeds with special treatment, and then mix with soil coagulant (you can also plant grass seeds first, then apply the soil) Coagulant). After the soil coagulant treatment, the grass seeds and soil will not be lost due to the wind and rain, and the coagulant will reduce the evaporation of water in the soil, which will ensure the water supply of the grass seeds to a certain extent and greatly improve The survival rate of grass seeds.
Through the growth activities of plants, the roots are reinforced, and the stems and leaves are protected against erosion. The three-dimensional vegetation network http://is treated by ecological slope protection technology, which can form dense vegetation cover on the slope surface and form the roots of the roots in the topsoil. Suppress the erosion of storm runoff on the slope, increase the shear strength of the soil, reduce the pore water pressure and the self-gravity of the soil, thus greatly improving the stability and erosion resistance of the slope.
The three-dimensional vegetation net slope protection technology combines the advantages of geonets and plant slope protection, and plays a role in compound slope protection. When the vegetation coverage of the slope reaches 30% or more, it can withstand the scouring of light rain, and it can withstand the torrential rain when the coverage rate reaches 80% or more. When the plants are flourishing, the runoff velocity that can resist erosion is 6m/s, which is more than twice that of the general turf. The existence of geonet has a good effect on reducing the evaporation of water in the slope soil and increasing the infiltration. At the same time, because the geonet material is black polyethylene, it has the function of heat absorption and heat preservation, which can promote seed germination and is beneficial to plant growth.
