Applications of Slope Protection Nets

    Slope protection nets are primarily used in mountainous and hilly regions to safeguard critical infrastructure such as highways, railways, and public facilities built near unstable slopes. These systems effectively mitigate risks posed by rockfalls and landslides, ensuring long-term stability.

Growing Demand Driven by Infrastructure Development

    With rapid infrastructure expansion in China, including remote areas now connected by highways, the need for slope protection has surged. Proactive slope management is essential to protect lives, property, and economic assets.

Flexible Slope Protection Nets: Key Advantages

    Widely adopted for highway embankments, reservoir slopes, and erosion control, flexible slope protection nets offer unmatched adaptability and durability, making them irreplaceable in geohazard mitigation. Below are their core components and installation guidelines:

  1. Anchor Rods

• Function: Critical for securing the net; categorized into upper and lower anchors.

• Standards:

  • Upper anchors: Minimum 16 mm steel wire rope with 80 kN tensile strength.

  • Lower anchors: Minimum 50 kN tensile strength.

• Note: Anchor integrity directly determines the system’s impact resistance.

  2. Support Cables

• Types: Transverse (16 mm diameter) and longitudinal cables.

• Role: Distribute dynamic loads across the net during impact events.

  3. Columns (Posts)

• Function: Serve as primary load-bearing points, transferring forces from the net to the ground.

• Specifications:

  • Hot-dip galvanized to resist corrosion (e.g., acid rain exposure).

  • Weak corrosion resistance compromises structural integrity and slope stability.

  4. Installation Protocols

• Pre-Construction: Follow detailed engineering drawings.

• Key Steps:

  • Ensure column foundations are firmly embedded.

  • Achieve seamless integration of concrete bases with terrain.

Why Flexible Nets Are Essential

    In geologically complex zones (e.g., highways, landslide-prone areas), these systems prevent rockfalls and slope failures, protecting pedestrians, vehicles, and infrastructure. Neglecting installation risks catastrophic damage to life and property.
