Active Protection Network is mainly composed into steel wire rope, ordinary steel grille (often called wire grill) and TECCO & reg; high-strength steel wire mesh into three categories, the first two by wire rope anchor and / or support rope fixed way, the latter by steel bolt (prestressing) and wire rope anchor (when using edge support rope), dedicated anchor plate and edge support rope fixed manner when necessary, as a flexible network system is mainly composed of covering the geological potential on the slope of disasters, in order to achieve its protective purpose (Figure 1), Table 1 lists the classification and protection features active protection system or major application conditions. Types and Uses Active Protection Network (including GAR2, GPS2, GER2 and GTC-65A), commonly used in the slope collapse, weathering, Slough, slippery or reinforcing protective slump class geological disasters, the distinctive feature is the use of the anchor system rod fixed and flexible, depending on the network, respectively, through the support rope and suture tensioning (wire rope or wire grid) or prestressed anchor (TECCO-65 grid) to realize the flexible part of the pre-tension network, thus Slope form a continuous support throughout their pre-tensioning operation of the system as close to the slope, and inhibit the formation of a local rock and soil movement or displacement or damage in the event of partial wrap tied after their (residence) in the vicinity of in situ prestressed, in order to achieve its active protection (reinforcement) function. The system in the construction process as close as possible to ensure that its slope, anchor orifice should be dug pits orifice (system layout flexibility can often take advantage of the natural low-lying position setting anchor).
