Slope Protection Mesh Gabion Mesh

Slope Protection Gabion Mesh High-Strength Flexible Protection Against Rockfall and Landslides for Highway/Railway, Mining, and Water Conservancy Slope Reinforcement Mesh Custom Specifications

II. Product Overview:

Slopes (such as highway/railway embankments, mining excavation faces, water conservancy dam slopes, and construction foundation pit slopes) often face safety hazards like landslides, rockfalls, soil erosion, and slope collapse. Traditional rigid protection methods (such as masonry rubble or concrete retaining walls) suffer from issues like "poor adaptability (inability to handle minor slope deformations), high costs, and ecological damage." This specialized slope protection gabion mesh is 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, 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 through "active prevention + passive blocking" for slope safety.

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

Addressing the characteristics of slopes—"complex terrain (steep slopes, isolated rocks, fissures), unstable geology (loose soil, fractured rock), harsh environments (rainwater erosion, UV exposure, large temperature variations), and long-term maintenance needs"—this solution highlights fundamental differences from rigid protection methods:

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

·Material and Strength Design:

oUses Q355 low-alloy steel wire (primary material, balancing strength and toughness) or Galfan (zinc-aluminum alloy) steel wire (for high corrosion resistance scenarios). Wire diameter ranges from 2.8-4.0mm (typically 3.2mm), with tensile strength ≥600MPa, elongation at break ≥15%, and mesh extensibility ≥20%. It can adapt to minor slope deformations (≤5cm) without breaking, avoiding localized damage caused by "hard impacts" in rigid protection systems.

oActive Reinforcement (Soil Slopes): Through a combination of "anchor rods + gabion mesh," the mesh tightly conforms to the slope surface, "bundling" loose soil into a cohesive mass to limit displacement and reduce soil erosion from 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 stabilization by 50% compared to mere spraying.

oPassive Blocking (Rock Slopes): Mesh apertures of 5cm×10cm or 8cm×15cm (capable of blocking rockfalls up to 30cm in diameter), with impact resistance ≥15kN/m². Upon rock impact, energy is absorbed through elastic deformation of the mesh (distributing force 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 for Extreme Slope Environments

·Surface Treatment Processes:

oHot-Dip Galvanizing (zinc coating ≥100μm, salt spray test ≥800 hours): Suitable for rocky slopes in dry areas, resisting rainwater and UV erosion, with a service life of 15-20 years.

oGalfan Coating + Plastic Coating (zinc-aluminum alloy content ≥95%, plastic coating thickness ≥0.8mm): Ideal for slopes in rainy, humid, or coastal areas (e.g., highway tunnel entrances/exits, coastal embankments). Salt spray test ≥1200 hours, with excellent resistance to soil corrosion (acidic/alkaline soil) and microbial erosion, offering a service life of 20-30 years.

·Extreme Environment Adaptability:

oLow-temperature regions (-30°C): Mesh material remains non-brittle, capable of withstanding snow and ice pressure (snow depth ≤50cm).

oHigh-temperature and sun-exposed 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:

oThe gabion mesh offers excellent extensibility, allowing flexible installation along undulating slopes (gradient 30°-70°) and around corners (e.g., convex/concave slopes, isolated rocks), with a conformity rate ≥95%. No cutting or splicing is required (avoiding protection gaps), making it ideal for irregular slopes with isolated rocks or fissures (where traditional welded meshes often create right-angle gaps).

oCustomizable Specifications: Mesh width 2-4m (typically 3m to reduce overlap), length cut to需求 (typically 50m/roll). Can be combined with "active protection nets (SNS)," "anchor rods," and "shotcrete" to form a multi-layer protection system (e.g., surface gabion mesh + deep anchor reinforcement).

·Ecological Compatibility:
Open mesh apertures (water permeability ≥90%) do not hinder rainwater infiltration or plant growth (grass seeds can germinate through the mesh). Compatible with slope vegetation restoration projects, avoiding ecological damage from "concretization" and meeting "green slope" construction requirements, especially for slopes near scenic areas and ecological reserves.

4.Easy Installation, Reduces Engineering Costs

·Lightweight and Efficient Installation:

oMesh weight ≤6kg per square meter, portable by manual labor. Paired 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㎡ daily), significantly shortening project timelines (especially in mountainous areas, reducing heavy machinery use).

·Economic Advantages:
Costs only 1/3 to 1/2 of concrete retaining walls. Simple maintenance (localized damage can be quickly repaired without full replacement), offering significant lifecycle cost savings. Ideal for small to medium-sized slope projects with limited budgets.

V. Applicable Scenarios: Covering All Types of Slope Engineering

·Core Engineering Scenarios:

oHighway/Railway Slopes: Mountain slopes alongside highways and railways (especially rocky slopes and fracture zones), preventing rockfalls from hitting roads and ensuring traffic safety.

oMining Slopes: High and steep slopes from open-pit mining, using active reinforcement to reduce landslide and collapse risks, protecting workers and equipment.

oWater Conservancy Project Slopes: Reservoir dams and channel slopes, preventing soil erosion from water flow, balancing ecology and protection.

oMunicipal 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.

oConstruction Foundation Pit Slopes: Temporary slope protection after deep excavation, preventing soil collapse and ensuring construction safety.
