Advantage of an Active Protection Network, active safety net system for factory and standardized production, construction speed. Yan Ping Road tens of thousands of square meters of construction, only two months duration, and does not affect other construction projects simultaneously. 2. Active Protection Network system takes full advantage of the flexible material is easy to spread and high anti-impact capability, through the system and the formation of a large number of field trials to adapt all kinds of geological disasters slope protection and natural slope of systematic techniques and facilitate project quality accurate measurement of the amount of control and engineering. 3, take full advantage of the characteristics of high strength and light weight and easy processing of metallic materials to achieve the system's light, parts production factory and building blocks installed in equipment as simple as possible, the shortest duration and minimal construction and installation work to achieve quick and easy to maintain, thus solving in complex mountainous terrain of traditional protective measures construction difficulties, slow progress in the long-term problem; and take advantage of the system's flexibility and construction layout to maximize flexibility to adapt to a variety of complex terrain environment, avoid or minimize environmental damage caused due to excavation and slope stability hazards, as well as interference to other jobs in and around the building to normal operations. 4, take full advantage of the openness of the system to reduce the system of visual disturbances and protect the existing vegetation and growth conditions, and to implement artificial afforestation may be provided, in order to take full advantage of the environment green vegetation roots slope reinforcement role and greenery landscaping function, project management and environmental protection and improvement of integration. 5, take full advantage of the technology is mature, cost-effective good metal corrosion coating technology, the use of galvanized steel wire rope and steel or zinc-aluminum coating to ensure corrosion protection system longer life, the former generally up to 30 to 50 years after by up to a hundred years, only a small number of components to extend the life of the replacement if necessary. GAR1 type Active Protection Network grid: DO / 08/300 support rope: Φ16 edge (or on the edge) anchor rope + Φ16 slope (or on the edge) support rope stitch rope: Φ8 Note: single wire rope, anchor length generally 2m-3m, pullout force is not less than 50KN.
