GPS2 type Active Protection Network is used for high-strength steel wire rope or TECCO main types of steel wire mesh grille covered or wrapped in a flexible mesh or dangerous rock slope protection necessary to limit or destroy the slope weathering of rock and soil, as well as crag collapse (reinforcement effect), or rockfall control within a certain range of motion (maintenance action). GPS2 type active protection system uses a network of high-strength galvanized steel wire rope, steel wire, not less than embalmed AB class, its antiseptic life depending on the environmental conditions in general up to 30-50 years. The main slope instability, potential expansion from falling rocks to prevent and treat dangerous slope to criss ф16 support rope, according to slope shape (4.5X4.5m or 4.8X4.8m) arranged in a square pattern counter, and in The main 4X4m pre Mobility suture tensioning rope, so that the system is subjected to a certain direction slope preload pressure, thereby increasing the stability of dangerous rock mass, prevent rockfall occurred, but the system does not affect the normal groundwater excretion, and to ecological management slope provides a prerequisite. Active Protection Network System: the use of plant roots and active protection systems combine to achieve ecological restoration, consolidation slope stability, promote the degradation of organic pollution, clean air, reduce noise of an environmentally friendly system.
