The SNS Passive Protective Netting System, a slope protection system, is composed of components such as wire rope nets, high-strength steel wire mesh, anchor bolts, I-beam columns, tension anchor ropes, energy dissipation rings, bases, and upper and lower support ropes. The system is assembled from steel columns and wire rope nets, forming a cohesive unit that provides slope protection for the protected area and then prevents the descent of collapsing rocks, thereby serving as a slope protection measure.
