Passive Fence Mesh wire rope or ring network (need to intercept the small piece of rock fall when additional layer of the wire grill), fixed system (anchor rod, anchor rope, rope base and support), reduced pressure ring and steel columns of four main parts. Steel columns and steel wire rope net connection that constitute a whole, to form the protection surface protection, to prevent the collapse of rock soil mass drop, the effect of slope protection.

Passive Fence of flexible and intercept intensity can absorb and disperse within 500 kj of rockfall impact kinetic energy, and energy dissipation design of ring and adopt the system of impact resistant ability to further improve the SNS Passive Fencecompared with rigid intercept and build by laying bricks or stones slurry retaining wall, changed the original construction craft, reduce time and money. Passive Fence is suitable for the building facilities have buffer zone near the mountains, the rockfall, slungshot, avalanche, mud-rock flow interception in the construction, avoid disaster for the destruction of buildings.

Passive fence material: steel wire rope net, rope and decompression ring structure: by the steel wire net or ring network (need to intercept the small piece of rock fall when additional layer of the wire grill), fixed system (anchor rod, anchor rope, rope base and support), reduced pressure ring and steel columns of four main parts.
