Passive Rockfall Barrier Fence / Spider Shaped Spiral Rockfall Net
Product description
Passive rockfall barrier system is installed bottom of the mountain
or slope to reduce and block the rockfalls and stones. When the
stones, rocks, snows are falling down the mountain or slopes, the
passive rockfall barrier system can reduce the impact of the
rockfalls and protect the people and properties' safety.
Main types of passive rockfall barrier systems are including steel
wire rope net and steel ring net.
Steel wire rope net. steel wire rope net can not only used for active rockfall barrier system, but also the passive rockfall barrier system. It is mainly composed of steel wire rope net, decompression rings, supporting rope, sewing rope and steel column. It has high tensile strength and can block the rockfalls within 750 kJ.
Steel wire ring net. Steel ring net is made of high quality hot dipped galvanized wire into circles. Different circle quantity have different block capacity. The steel ring net can block the rockfalls within 2000 kJ. Steel ring net system is commonly made of steel ring net, supporting rope, anchor rope, sewing rope and metal column.
Main Components: The spider shaped rock protection system consists of the spiral rope net, nails and anchors, spike plates as standard anchorage, border and temporary ropes and net connection elements.

Slope protection mesh features:
High strength.
Short installation period
Less weight, easy to transport
Good ventilation
Excellent corrosion resistance
Easy maintenance
Applications:
Rockfall Net method stabilizes unstable slope surface using the combination of rock bolts and wire ropes. By tightening wire ropes, it is possible to hold back the loosened slope ground so that small scale surface sliding will be prevented.
