Passive Slope Protection Mesh

Passive Slope Rockfall Barrier 500–2000kJ Complete Protection System
Passive slope protection mesh are full interception systems set at slope toes
to catch falling rock masses, distinct from surface-mounted active slope mesh.
Each complete system includes galvanized steel posts, ring nets or wire rope
panels, support ropes, energy dissipating brake rings, and anchoring fittings.
Standard engineering energy ratings range from 250kJ to 2000kJ; common barrier
heights are 2–6m with 8/10mm wire rope nets and 12–20mm support ropes.
Layout, post spacing and anchor schemes are fully determined by rockfall
calculation reports. Widely deployed along mountain highways, railway cuttings,
tunnel portals and open mine slopes, all configurations are tailored to site
terrain.
Passive Slope Protection Mesh is a rockfall barrier system installed at the
slope toe, road side, or across a known rockfall path. It is used to intercept
falling stones after they separate from the slope surface. A complete system
normally includes steel posts, ring net or wire rope net panels, upper and
lower support ropes, anchors, base plates, brake devices, and connection
hardware. It is different from active slope mesh, which lies close to the slope
face. For Passive Slope Protection Mesh, the barrier height, energy rating,
post spacing, anchor type, and foundation details should be confirmed from the
rockfall design report before production.
