Green 3D earth slope protection net

Advantage：

Improve slope stability: three-dimensional vegetation network slope protection technology combines the advantages of geotechnical network and plant slope protection. and plays a role of compound slope protection. When the plants grow lush. the runoff flow rate that can resist erosion reaches 6m/s. more than twice that of the general turf. The existence of geotechnical mesh has a good effect on reducing the evaporation of soil water and increasing the infiltration. At the same time. because the geomesh material is black polyethylene. it has the effect of heat absorption and heat preservation. which can promote seed germination and is conducive to plant growth.

Preventing soil erosion: The role of vegetation in the three-dimensional vegetation network is mainly considered from three parts. the first part is the growth layer of plants. the second part is the detritus layer. and the third part is the root layer. The installation of three-dimensional vegetation network can control the erosion of slope by rainstorm and strong wind to a certain extent. increase the soil firmness. reduce the water pressure between pores and the soil self-gravity. and reduce soil erosion.

Promote vegetation growth: The three-dimensional vegetation network is made of active substances and synthetic materials. so it can absorb a lot of heat energy. enhance the ground temperature. promote grass germination. and extend the growth cycle of grass.

Economic and environmental protection: three-dimensional vegetation network slope protection technology not only significantly improves the overall and local stability of the slope. but also conducive to the growth of slope vegetation. while the

project cost is also low. in line with the development direction of slope engineering. in China's soil and water conservation has great application value.

Construction technology：

Folding slope treatment

Clean up the debris on the slope. and tamp down the low-lying areas to ensure that the slope is smooth.

Folding and laying three-dimensional mesh

(1)The three-dimensional vegetation net is laid on the slope from top to bottom along the slope. and the smooth combination between the net and the slope is maintained.

(2) When the embedded three-dimensional mesh is laid on the top of the slope. it should be extended by 40~80cm. buried in the soil and compacted.

(3) The anchoring three-dimensional network is fixed from the bottom up with the U-shaped steel bar above 6mm. U-shaped steel bar length is about 15~30cm. width is about 8mm. U-shaped steel bar spacing is about 1.5~2.5m. and the middle is assisted by 8# U-shaped iron nails or bamboo nails.

(4) The soil covering three-dimensional vegetation network is laid. the soil is evenly covered in the three-dimensional vegetation network. the net package is covered until there is no empty package. and the thickness of the soil on the three-dimensional vegetation network is not less than 12mm. Then the fertilizer. growth hormone. cement mixed evenly according to a certain proportion. sprinkle on the surface. Fertilizer for nitrogen: phosphorus: potassium =15:15:15 or nitrogen: phosphorus: potassium =10:8:7 compound fertilizer and organic matter containing N. the fertilizer amount is about 30~50g/㎡.

Folding spray seeding

After soil cover and backfilling is completed. hydraulic spraying is carried out. that is. grass seeds (spraying about 25 grams per square meter) and the adhesive. wood fiber. fertilizer. growth hormone. humectant and water that promote their growth are mixed and stirred in a certain proportion to form a uniform mixture. which is evenly sprayed on the slope through the hydraulic spraying machine.

Folding cover

After the construction is completed. the surface of the slope is covered with non-woven fabric to keep the moisture on the slope and reduce the erosion of the seeds by rainfall. so as to promote the seed growth. If the temperature is too high. there is no need to cover. so as to avoid the occurrence of diseases and pests.

Folding maintenance management

After the completion of the grass spraying construction. maintenance must be carried out regularly until the lawn is flat. When the lawn is about 5cm long. the non-woven fabric can be uncovered.
