Passive Rockfall Protection Fence

Passive Rockfall Protection Barrier systems are such that do not affect rock detachment process, focusing rather on containing falling debris, thereby minimizing risks to the infrastructure and its users. Passive mitigation is necessary when the scenario is intended as a preventive way of controlling rockfalls. This method is usually used in areas that are not fractured or where slopes have already been worked with slope stabilization measures.

In certain rockfall hazard situations, it may not be practical to install rockfall drapery mesh protection or surface stabilization mesh due to scale, complexity, technical, topographic, access or economic issues. In these cases, a cost-effective solution is provided by installing passive rockfall barriers.

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.

Passive Rockfall Protection Barrier systems include:

Steel Wire Cabel 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 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.
