An Innovative Solution for Slope Protection and Ecological Restoration

Product Description

The three-dimensional vegetation net is a plastic mesh featuring a three-dimensional arched structure, primarily made of polyethylene or polypropylene. It consists of a high-modulus base layer (biaxially stretched flat mesh) and multiple layers of concave-convex plastic mesh. The surface and bottom layers are thermally bonded at connection points to form a stable three-dimensional network structure.

Working Principle

• Erosion Resistance by Vegetation: Achieved through the plant growth layer, humus layer, and root layer, which prevent soil erosion, provide a protective cover, and reinforce anchoring.

• Reinforcement by 3D Mesh: Enhances mechanical stability within a certain thickness range. Plant roots intertwine with the mesh to form a plate-like structure, increasing tensile and shear strength while preventing shallow slope sliding and bulging.

Key Features

• Superior Protection: Effectively prevents soil erosion before vegetation establishes, shielding slopes from wind, rain, and flood damage.

• Promotes Plant Growth: Secures seeds evenly on slopes while absorbing heat to elevate ground temperature, accelerating germination and growth.

• Energy Dissipation: The uneven surface creates micro-vortices in wind and water flow, reducing velocity and minimizing soil particle loss.

• Easy Installation: Flexible and lightweight for effortless deployment; can be transplanted as pre-grown grass mats for rapid slope stabilization.

Construction Process

1. Slope Preparation: Clear debris and loose rocks; round off sharp edges for smooth transitions.

2. Drainage System: Install ditches at the crest, toe, and platforms; add slope drains if needed to prevent runoff.

3. Mesh Installation: Unroll the net top-to-bottom, embed the top edge in the crest ditch, overlap adjacent rolls, and secure with U-shaped pins.

4. Soil Spraying: Apply a ≥5 cm layer of mixed humus and organic fertilizer, ensuring full coverage without exposed or compressed mesh.

5. Seed Hydroseeding: Spray a slurry of seeds, fiber, binder, water-retaining agents, and fertilizer uniformly.

6. Covering: Lay 14 g/m² non-woven fabric secured with bamboo pins; remove once plants reach ~3 cm.

7. Maintenance: Maintain moisture and nutrients during germination; manage watering, fertilizing, and pest control.

Applications

1. Highway & Railway Slope Protection

In road and rail construction, steep cut-and-fill slopes are prone to erosion and collapse. The 3D vegetation net stabilizes soil, combats rain/wind erosion, and enhances aesthetics. For example, in mountainous areas with loose soil or fractured rock, it significantly reduces landslide risks, ensuring traffic safety.

2. Mine Slope Rehabilitation

Post-mining slopes often face ecological degradation. The net accelerates revegetation, aiding ecosystem recovery. In open-pit coal mines, it enables rapid greening while preventing spoil weathering and erosion.

3. Riverbank Protection

Vulnerable to scouring, riverbanks benefit from the net’s erosion resistance and root reinforcement. Urban river projects use it to stabilize banks and create aquatic habitats, improving water ecosystems.

4. Hydraulic Engineering Slopes

Reservoirs and dams require stable, erosion-resistant slopes. The net reduces soil loss, while plant roots add reinforcement and lower surface temperatures. Small reservoirs employ it for both functionality and visual harmony.

A sustainable fusion of engineering and ecology, the 3D vegetation net transforms vulnerable slopes into resilient, green landscapes.
