Spider Type Protection Net for Broken Rock Faces and High-Requirement Slope Anchoring

Spider type protection net uses high-strength wire rope mesh with a diagonal, spider-like layout to clamp fractured rock surfaces tightly. It is selected where ordinary mesh needs more tensile strength and better force transfer around anchors.

The system is suitable for steep rock slopes, tunnel portals, cut slopes, and locations with blocky or highly fractured rock. Rope diameter, mesh spacing, anchor pattern, edge rope, and clamp details can be designed to suit the slope.

Product Advantages
  • High-strength wire: Designed around high-strength wire to match key engineering needs more directly.
  • Adaptable to complex terrain: Can be configured according to slope shape, geological conditions, and protection level.
  • Strong system compatibility: Can work with anchors, support ropes, and connectors to form a complete protection system.
  • Custom specifications: Size, material, surface treatment, and accessories can be adjusted by drawings or project requirements.
  • Easy maintenance: Clear structure supports later inspection, local replacement, and routine maintenance.
Structure

Spider Type Protection Net is made from high-strength wire ropes woven or crossed into a net and fixed with border ropes, anchors, clamps, and tensioning nodes. Its large openings and high tensile capacity make it suitable for fractured rock faces requiring combined local and surface restraint.

Working Principle

Spider Type Protection Net connects unstable rock between anchor points into one load-sharing system. After tensioning, the rope mesh applies restraint to the rock face, and loads from loose blocks are transferred through the mesh to anchors and stable rock, making it suitable for fractured surfaces.
