Features: 1. Turf not grown up, you can protect the land surface erosion from wind and rain. 2 can be firmly maintained grass seed evenly distributed on the slope, the red and the loss from wind and rain. 3 black mat mass absorbs heat energy, increased wet and promote seed germination and extend the growing season. 4 due to the rough surface, so that the wind, the water flow at the surface of the mat countless eddy thus generate energy dissipation, promote its portable mat deposition. 5 composite protective layer is formed after the plants grow up, can be subjected to high water level, a large velocity erosion (two days may be subjected to a 3 - 4m / s, 4 - 5 hours, 5-6m / s) may be subjected to. 6. Permanent alternative to concrete, asphalt, stone and other slope protection material for roads, railways, rivers, dams, slopes and slope protection. Can greatly reduce the project cost is C15 concrete and dry block the stone revetment cost 1/7 the the mortared stone cost 1/8. Sand land surface laying prevent sand dunes of mobile, can greatly improve the surface roughness, increased surface sediments, the changing surface physical and chemical properties, to improve the local ecological environment. The basic principles of the three-dimensional vegetation net slope protection. 3D vegetation net slope protection concept of three-dimensional vegetation net slope protection refers to the combined use of active plant and geosynthetic materials engineering materials, to build a protection system with its own ability to grow in the slope, through the growth of plants slope reinforcement of a new technology. Slope topography, soil quality and regional climate characteristics, slope surface covering layer of geosynthetic materials and press a certain combination of spacing planting a variety of plants. Root reinforced by the activities of plant growth, stems and leaves of the purpose of the anti-erosion, after the processing of ecological slope protection technology, in the slope to form a dense vegetation cover to form intertwined roots in the topsoil, the effective suppression of stormwater runoff on the slope erosion, increasing the shear strength of the soil, reducing the pore water pressure and soil from gravity, thus greatly improving the slope stability and anti-erosion ability. Reinforcement mechanism of 3D vegetation net vegetation erosion is achieved through three main components: prevent plant growth layer (including the the perianth, sheaths, leaves, stems), dense coverage through their own slope topsoil directly from rain erosion, reduce stormwater runoff, erosion energy and surface runoff speed, so as to reduce the loss of soil; humus layer interface (including in leaf litter and roots), as the slope topsoil a protective layer; roots layer, this part of the the slope surface soil reinforced anchor, provides mechanical stability role. Under normal circumstances, in the early stage of plant growth, individual plants formed roots only loosely intertwined, not long lying roots easy separation with soil, no protection. Three-dimensional network is to achieve a more thorough enhance the effects of the above three shallow protection. First, within a certain range of the thickness and increase its protective properties and mechanical stability; second is due to the presence of a three-dimensional network, extensive root system and the three-dimensional network of the plant net rib connected together to form a plate structure (corresponding to the slope surface soil reinforcement) of the protective layer, thus increasing the tensile strength and shear strength, restrict the erosion case caused gradual destruction "(erosion interested individual plant directly damage over time, the damaged area plus large) extension of the phenomenon, and ultimately limit the the slope shallow surface sliding and uplift the occurrence. 3D vegetation net slope protection vegetation of the role of three-dimensional mesh slope protection technology integrated geonets slope of the advantages and plants, has played the role of composite revetment. The slope vegetation coverage rate of 30% or more, can withstand rain erosion, more than 80% coverage can withstand heavy rain erosion. Subject to the lush plant growth, resistant to erosion runoff velocity of 6m / s, more than 2 times the general turf. The Geonet exist have a good effect on reducing the the slope soil's moisture evaporation, increase infiltration. Geonet material black polyethylene endothermic insulation can promote seed germination, is conducive to plant growth. 4. A rapid protective measures (1) When the duration and vegetation establishment period contradictions in the works that enter the storm season just completed, the need to take "reinforced turf works fast protection order can be obtained after the completion of the comprehensive coverage of the anti- scour vegetation. Reinforced turf "three-dimensional vegetation net in the open space on the lawn plantations or near the site of the pre-cultivated turf, rolled into the floor to the entire volume or block, and then laid to required slope protection. (2) in difficult governance arid regions, may use soil coagulant, a good choice of suitable grass seed coagulant mixing with soil spray (after special treatment before sowing grass seed, and then the application of soil coagulant ). Slope, grass seed and soil treatment by the soil coagulant will not be lost due to wind and rain coagulant reduce the evaporation of the moisture in the soil, grass seeds to ensure the water supply to a certain extent, greatly improving the survival rate of the grass seed. Construction process. Slope processing will slope on and miscellaneous stone debris clean backfill compaction formation of the lower-lying areas, to ensure a smooth slope. Laying three-dimensional network ⑴ laying along the slope of the three-dimensional vegetation net Shop from top to bottom in the slope between the network and the slope to maintain smooth combination. Shop at the top of the hill when the the ⑵ embedded three-dimensional network need to extend 40 ~ 80cm, buried and compacted soil. And ⑶ anchor the three-dimensional network bottom-up with U-reinforced ф6mm more three-dimensional network fixed, U-shaped steel bar is about 15 ~ 30cm, width of 8mm, U-bar spacing of about 1.5 ~~ 2.5m middle with 8 # U nails or the bamboo nail auxiliary fixed. ⑷ to overburden dimensional vegetation net laid, dirt uniform coverage in the three-dimensional vegetation online, mesh coated cover until the empty package to ensure that the the 3D vegetation online soil thickness not less than 12 mm. Then fertilizer, auxin, cement, according to a certain proportion of mixed, applied sprinkling on the surface. Fertilizer nitrogen: phosphorus: potassium = 15:15:15 or nitrogen: phosphorus: potassium = 10:8:7 fertilizer and N-containing organic matter, fertilizer about 30 ~ 50g / ㎡. 3. Seeding overburden backfill is completed, Hydraulic Spraying upcoming grass seeds (per the square 25 grams Seeding) and to promote its growth and adhesion agents, wood fiber, fertilizer, auxin, moisturizing and water by mixing stirring to form a uniform mixture evenly sprayed on the slope on Hydraulic Spraying machine. Coverage hydroseeding grass construction completed in the slope surface covering non-woven to keep the slope water and reduce the erosion of rainfall on seed, prompting seed. If the temperature is too high, you do not need the coverage, in order to avoid the occurrence of pests and diseases. 5. Conservation and management hydroseeding construction is completed, it is necessary to conduct regular maintenance, until the lawn into the floor. After the lawn grow to about 5cm, you can uncover the non-woven three-dimensional geomat Product Description: Three Dimensional Geonet based thermoplastic resin as raw material by extrusion into the net, stretching, spot welding composite processes made was the the multilayer plastic three-dimensional structure bubbly bump mat surface, it is the ground floor of a high film base layer to prevent deformation and soil erosion, surface foaming layer, fill soil, planted grass seed is ideal soil and vegetation protection materials. Specification is divided into: EM2, EM3, EM4, EM5. Not grown up in the turf, you can protect the land surface erosion from wind and rain, both the solid grass seed sown early; the composite protection of plant growth up layer can withstand high water level, velocity rainfall; alternative to concrete, asphalt , riprap slope protection material, mainly used in highways, railways, rivers, dams, hillside slope protection. The 3D geomat is the application of a three-dimensional structure of the new geosynthetics in soil and water conservation can be effective to prevent soil erosion and increase green space, improve the ecological environment. An alternative to concrete, asphalt, riprap slope protection material, mainly used in highways, railways, rivers, dams, hillside slope protection. 2, before the grass did not grow into, you can protect the land from wind and rain erosion. 3, after the formation of the plants grow up the composite protective layer may be subjected to the high water mark, a large flow scouring. 4, can significantly reduce the project cost, the cost of concrete revetment and dry masonry stone revetment only 1/7, the mortared stone 1/8. 5, the use of polymer materials as well as UV resistant UV stabilizers, its high chemical stability, environmental pollution (degradation net pad after two years in the soil may leave marks). 6, the construction is simple, in the smoothness of the surface, can construction. 3D vegetation net protection advantages, the surface layer of the three-dimensional vegetation net as a foaming layer, fluffy network packets larger capacity of soil, grass coverage, this three-dimensional structure to ensure that the grass seeds better with soil. 3D vegetation net slope protection against wind, rain, floods, erosion can effectively protect the slope. The three-dimensional vegetation net based thermoplastic resin as raw material. Using scientific formula, by extrusion, stretching welding, shrink craft made of two or more layers of the surface was uneven network packet-like layered structure hole net, it is non-corrosive, acid and alkali. 3D vegetation net ground floor of a high modulus of the base layer, biaxially oriented technology, with a certain degree of flexibility and strength, and to prevent vegetation mesh deformation, and can effectively prevent soil erosion. 3D vegetation net surface as a foaming layer, fluffy network packets larger capacity of soil, grass coverage, this three-dimensional structure to ensure that the grass seeds better with soil. 3D vegetation net slope protection against wind, rain, floods, erosion can effectively protect the slope. 3D vegetation net initial function is conducive to the growth of vegetation, and its main function is to help with the formation of vegetation grassroots system to enhance its resistance to the natural soil erosion ability. The three-dimensional vegetation net slope protection has the following main features: network package, to reduce the impact energy of raindrops vegetation net surface uneven, wind and currents can have a small whirlpool in its surface, play a buffer role of energy dissipation, reduce flow rate, thereby effectively resist the erosion of rain; fillings Bags (soil particles, nutritive soil, grass seed, etc.) can be fixed to reduce the loss of rain erosion; Slope plays topsoil plus the role of reinforcement, so as to effectively prevent the surface soil slip; dimensional vegetation net helps the uniform growth of vegetation, the roots of the vegetation growth slope soil easily fixed; dimensional vegetation net made the grass blanket The offsite transplantation can solve the need of the rapid vegetation protection works requirements. Proved: prior to the formation of the turf, when the slope of 45 degrees, three-dimensional vegetation mat solid soil block rate up to 97.5%, flat net 74%; solid soil resistance when the slope is 60 degrees, the three-dimensional vegetation mat stagnation rate was 84%, 0% flat net, lost the solid earth; slope of 90 degrees, the three-dimensional vegetation mat may retain 60% of the soil block live. This shows that the use of three-dimensional vegetation mat has excellent solid earth, far better than the flat net plane network replacement products. The advantages of 3D vegetation net protection: three-dimensional vegetation net slope protection has the advantages of simple construction technology, short construction period, low-cost, small quantities, the protective effect. Currently, the high road landscape, especially in scenic scenic roads and country parks on the mountain, traditional masonry masonry protection seriously undermine the original natural vegetation, resulting in a lot of bare soil slope surface, can not meet the aesthetic requirements of the people. 3D vegetation net has its own unique advantages.
