Engineering Slope Protection Net

Engineering Slope Protection Gabion Mesh High-Strength Flexible Protection Rockfall and Landslide Prevention Highway/Railway / Mining / Hydraulic Slope Reinforcement Net

II. Product Overview:

Engineering slopes (such as highway/railway side slopes, mining excavation surfaces, hydraulic dam slopes) often face safety hazards like landslides, rockfalls, soil erosion, and slope collapse. Traditional rigid protection methods (such as mortar rubble or concrete retaining walls) suffer from issues like "poor adaptability (unable to handle slope deformation), high cost, and ecological damage." This engineering slope protection gabion mesh is specifically designed to address these pain points. It is woven from high-strength metal wires and can be customized based on slope gradient (≤70°), soil/rock type (soil/rock), and hazard level (small rockfalls/shallow landslides). It features "flexible blocking, active reinforcement, weather resistance, corrosion resistance, and ecological compatibility," complying with the "Highway Subgrade Design Code" and "Building Slope Engineering Technical Code," providing dual protection of "active prevention + passive blocking" for slope safety.

III. Core Advantages: "Flexible Protection" Features Tailored for Slope Scenarios

Considering the characteristics of engineering slopes—"complex terrain (steep slopes, isolated rocks), unstable geology (loose soil, fractured rock), harsh environment (rainwater erosion, UV exposure), and long-term maintenance needs"—this product highlights its fundamental differences from rigid protection methods:

1. Flexible Reinforcement + Active Blocking, Dual Protection Against Hazards

• Material and Strength Design:
  • Uses Q355 low-alloy steel wire (primary material, balancing strength and toughness) or Galfan (zinc-aluminum alloy) steel wire (for high corrosion resistance scenarios), with wire diameters of 2.8-4.0mm (typically 3.2mm), tensile strength ≥600MPa, elongation at break ≥15%, and mesh extensibility ≥20%, allowing it to adapt to minor slope deformations (≤5cm) without breaking.
  • Active Reinforcement (for soil slopes): Through a combination of "anchor rods + gabion mesh," the mesh tightly adheres to the slope surface, "bundling" loose soil into a cohesive mass to limit soil displacement and reduce erosion caused by rainwater. Combined with vegetation restoration (the mesh serves as a climbing frame for plants), it forms a "mesh-soil-vegetation" composite protection system, improving soil fixation effectiveness by 50% compared to mere spray seeding.
  • Passive Blocking (for rock slopes): Mesh openings of 5cm×10cm or 8cm×15cm (capable of blocking rockfalls with diameters ≤30cm), with impact resistance strength ≥15kN/m². Upon rock impact, energy is absorbed through elastic deformation of the mesh (impact force distributed across the entire mesh and anchor rods), preventing localized damage. Blocking efficiency is 30% higher than rigid retaining walls (especially for small, scattered rockfalls).

2. Weather and Corrosion Resistance, Adapting to Harsh Slope Environments

• Surface Treatment Processes:
  • Hot-dip galvanizing (zinc coating thickness ≥100μm, salt spray test ≥800 hours): Suitable for rock slopes in dry regions, resisting rainwater and UV erosion, with a service life of 15-20 years.
  • Galfan coating + plastic coating (zinc-aluminum alloy content ≥95%, plastic coating thickness ≥0.8mm): Suitable for slopes in rainy, humid, or coastal areas (e.g., highway tunnel entrances/exits), with salt spray test ≥1200 hours, excellent resistance to soil corrosion (acidic/alkaline soil) and microbial erosion, and a service life of 20-30 years.
• Extreme Environment Adaptability:
  • Low-temperature regions (-30°C): Material remains non-brittle, capable of withstanding snow accumulation (snow depth ≤50cm).
  • High-temperature and high-exposure regions (60°C): Plastic coating does not peel or powder, maintaining flexibility and preventing mesh aging and cracking.

3. Conforms to Terrain, Adapts to Complex Slope Conditions

• Flexibility and Terrain Adaptability:
  • The gabion mesh offers excellent extensibility, allowing flexible installation along slope undulations (gradient 30°-70°) and corners (e.g., convex or concave slopes), with ≥95% conformity. No cutting or splicing is required (avoiding protection gaps), making it especially suitable for irregular slopes with isolated rocks or fissures.
  • Customizable specifications: Mesh width 2-4m (typically 3m to reduce overlap), length cut to requirement (typically 50m/roll). Can be combined with "active protective nets (SNS)," "anchor rods," "shotcrete," etc., to form a multi-layer protection system (e.g., surface gabion mesh + deep anchor rod reinforcement).
• Ecological Compatibility:
  Open mesh design (water permeability ≥90%) does not hinder rainwater infiltration or plant growth (grass seeds can germinate through the mesh openings). Compatible with slope vegetation restoration projects, avoiding ecological damage from "concretization" and meeting "green slope" construction requirements.

4. Easy Installation, Shortens Construction Time and Reduces Costs

• Installation Efficiency and Economic Benefits:
  • Lightweight design (weight ≤6kg per square meter), allowing manual handling. Combined with "slope-specific anchor rods" (length 1-2m, customized based on soil/rock hardness), installation efficiency is 5 times higher than rigid retaining walls (a 10-person team can install 500㎡ per day), significantly shortening construction time (especially for mountain slopes, reducing the need for heavy machinery).
  • Cost is only 1/3 to 1/2 that of concrete retaining walls. Simple maintenance (local damage can be quickly repaired without full replacement), offering significant lifecycle cost advantages.

V. Applicable Scenarios: Covering All Types of Engineering Slopes

• Core Engineering Scenarios:
  • Highway/Railway Slopes: Mountain slopes alongside highways and railways (especially rock slopes and fracture zones), preventing rockfalls from hitting the road and ensuring traffic safety.
  • Mining Slopes: High and steep slopes formed by open-pit mining, reducing landslide and collapse risks through active reinforcement, protecting workers and equipment.
  • Hydraulic Engineering Slopes: Reservoir dam and channel slopes, preventing soil erosion caused by water flow, balancing ecology and protection.
  • Municipal and Industrial Area Slopes: Fill and cut slopes in urban development zones and industrial areas, combined with vegetation restoration to create "safe + aesthetically pleasing" green slopes.
