Slope protection netting-also known as SNS slope protection netting, flexible slope protection netting, or steel wire rope netting-is a type of equipment used to protect against landslides along highways and railways; it is primarily categorized into active protection systems, passive protection systems, and ring-net systems.
Active protection systems utilize steel wire rope netting to cover the slope, limiting the weathering and spalling of rock masses and containing the spread of falling rocks; they also offer environmental benefits and are suitable for stabilizing slopes with large rock masses. Passive protection systems consist of steel wire rope netting, ring nets, anchoring systems, steel posts, and energy-dissipating rings; they intercept falling rock masses through surface coverage and are suitable for slopes prone to loose rockfall, with their positioning and height determined based on rockfall trajectories.
The system employs a modular installation process characterized by high flexibility and adaptability, resulting in short construction periods and minimal environmental impact. Installation steps include surveying and positioning, securing the base, and laying out the support ropes and netting. Technological advancements emphasize deep reinforcement and comprehensive management strategies, incorporating measures such as anchoring, drainage, and concrete shear reinforcement.
