Spider Type Protection Net

Home Products Slope Protection SystemSpider Type Protection Net

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

The spider-type protection net adopts a two-layer slope reinforcement structure. The outer layer uses high-strength wire rope mesh as the main load-bearing layer, while the inner fine mesh is fitted with chain link mesh to closely cover the slope surface and restrain loose fragments. The two layers are fixed with anchors, boundary ropes, clamps, and tensioning nodes, forming a combined point-and-surface reinforcement system for fractured rock slopes.

Working Principle

After tensioning, the outer wire rope mesh connects unstable rock blocks between anchor points into an integrated load-bearing system, transferring local rock pressure to the anchors and stable rock mass. The inner chain link mesh stays close to the slope surface, helping restrain smaller stones and weathered surface layers, reducing fragment fall and improving overall slope stability.
