Slope protection netting is primarily used to safeguard slopes or rock faces, preventing natural disasters such as weathering, spalling, and the collapse of unstable rock masses. The following are several major types of slope protection netting and their key characteristics:
Active Protection Netting
Active protection netting primarily consists of flexible mesh-such as steel wire rope mesh-draped over the slope or rock face requiring protection. Its purpose is to restrain the weathering, spalling, or deterioration of the surface soil and rock strata, as well as to prevent the collapse of unstable rock masses.
Due to the open structure of the system, active protection netting also preserves the natural vegetation and growth conditions on the slope surface, while simultaneously allowing for the implementation of artificial revegetation measures.
Passive Protection Netting
Passive protection netting is composed of four main components: steel wire rope mesh, ring nets, a anchoring system, energy-absorbing rings, and steel support columns.
It functions as a passive interception barrier, effectively absorbing the impact energy generated by natural disasters such as rockfalls, landslides, and avalanches, thereby protecting nearby personnel, buildings, and infrastructure from damage.
Ring Net Protection Netting
Ring net protection netting is constructed by coiling multiple strands of steel wire into individual rings that are then interlinked to form a cohesive mesh.
It possesses exceptional flexibility and tensile strength, allowing it to adapt to complex terrain while providing highly effective protection against large-volume rockfalls.
Twisted Cable Net Protection Netting
Twisted cable net protection netting utilizes high-strength steel wire as its primary material, which is fabricated through a specialized twisting process.
Characterized by its resistance to corrosion and abrasion, as well as its robust protective capabilities, this type of netting is ideally suited for slope protection applications in a wide range of harsh environmental conditions.
