Active Protection System is the main types of rope wrapped in a flexible network coverage required protective slope or rock, to limit the slope of weathered rock or soil damage and spalling crag collapse (reinforcement effect), or the rockfall control in within a certain range of motion (maintenance action). The system features: high flexibility, high protection strength, easy auxiliary malleable. Adapt to any terrain slope, the installer standardized and systematic. The system uses die-cutting of installation, short duration, low construction costs. Special manufacturing processes and high corrosion preventive materials technology systems, determines the ultra life of the system. Systems engineering team can affect the environment to a minimum, the protection zone can adequately protect the soil, rock solid, easy to artificial green, environmentally friendly. Active Protection Network architecture configurations: metal, bolts, support rope, rope stitching, mesh grille. SNS flexible protection is a high-strength steel wire flexible net (diamond wire rope, ring networks, high-strength steel wire grid) as the main component, and to cover, fastening to prevent rock slope collapse, rolled, flying stone blasting hazards. The system has been studied and improved our R & D staff, is that the technology is well developed and applied. Flexible protection of its mature technology, perfect construction application technology, standard modular operation, the slope flexible protection system has been used in a large-scale disaster prevention Slope address.
