Geonet slope concept Geonet slope refers to the use of active plant combined with geosynthetics and other engineering materials to build a protection system that has the ability to grow on the slope, a new reinforced by the growth of plants on the slope technology. Slope topography, soil characteristics and regional climate, the slope surface covered with a layer of geosynthetics and press a certain combination of planting a variety of plants and spacing. To root reinforcement by plant growth activities, the purpose of stem anti-erosion, ecological slope protection technology processing, can be formed on the slope dense vegetation cover, the tangled roots formed in the surface soil, effectively inhibit the stormwater runoff on the slope erosion, increasing soil shear strength, reducing the pore water pressure and soil from gravity to dramatically improve slope stability and anti-erosion ability. On reinforcement mechanism of the three-dimensional vegetation net vegetation anti-erosion is achieved through its three major components: plant growth layer (including perianth sheath, leaf, stem), through its own dense cover to prevent slope surface soil directly affected by rain erosion, reduce stormwater runoff erosion energy and runoff velocity, thereby reducing the loss of soil; humus layer (including leaf litter and roots interface) provides a protection for the slope surface soil layer; root zone, this part of the surface soil slope reinforced anchor, the role of mechanical stability. General case, in the early stage of plant growth, due to the formation of roots of the individual plant is only loosely intertwined None Length lying roots, separation easy and soil and no protection. The application of the three-dimensional network precisely to achieve a more thorough shallow protected from enhanced the effect of the above three. First, in a certain range of the thickness and increase its protective properties and mechanical stability; second is due to the presence of the three-dimensional network, the plants of the the huge roots with a three-dimensional network of bars connected together to form a plate structure (equivalent to the slope surface soil reinforcement), which increases the tensile strength and shear strength of the protective layer, limiting the erosion caused by "undermine" (erosion interested individual plant directly damage over time, the damaged area plus large) expansion of the phenomenon, which ultimately limits the occurrence of the slope shallow surface sliding and uplift. The Geonet slope of the role of geotextile mat slope protection technology combines geonet slope of the advantages and plants, played a composite slope. The slope vegetation coverage rate reached more than 30%, can withstand light rain erosion, coverage of more than 80% can withstand heavy rain erosion. To be lush plant growth, resistance to erosion runoff flow rate up to 6m / s, more than twice the normal turf. The geonet the presence of, have a good effect on the slope to reduce soil moisture evaporation, increase infiltration. Also, because the the geonet material black polyethylene endothermic insulation, promote seed germination, is conducive to plant growth. The rapid protective measures (1) can be obtained when the duration and vegetation establishment period conflict need to be taken in the project just completed into the storm season, reinforced turf "protection of works fast, in order to be completed comprehensive coverage of vegetation against erosion . Reinforced turf using three-dimensional vegetation net pre-cultivated turf lawn plantations or near the site of the open space, the entire volume or sub-block into the floor can be rolled up, and then laying on the slope to be protective. (2) difficult to control in the arid regions, soil coagulant, a good choice of suitable seeds, after special treatment, mixing with the soil coagulant spray (can also be sowing seeds, and after the application of soil coagulant ). Soil coagulant treatment slope, grass seed and soil loss due to wind and rain will not, the coagulant and reduce the evaporation of moisture in the soil, to a certain extent to ensure the water supply of seeds, greatly improving the survival rate of the seeds.
