Hebei Hengshui Gucheng Peng Cheng sales of various types of high quality flexible protection initiative SNS SNS SNS Active Protection System Active Protection System principles constitute divided by major steel wire rope, ordinary steel grille (often called wire grill) and high intensity TECCO steel grille three categories, the first two by wire rope anchor or support rope fixed way, the latter through the steel (can be prestressed) or wire rope anchor (when using edge support rope), dedicated anchor plate and, if necessary edge support rope and other fixed manner, as a flexible network system is mainly composed of covering the slope of potential geological disasters, in order to achieve its protective purpose. SNS Active Protection System commonly used in the standard slope collapse, boulders and falling rocks, weathering, Slough, slippery or slumping Geological Disaster reinforced protection, its distinctive feature is the use of a fixed anchor system and flexible network based on different respectively, through the support rope and suture tensioning (wire rope and wire grill) or prestressed anchor (TECCO-65 grid) to achieve the pretension of flexible net part, thus forming a continuous support of the entire slope, its pre-tensioning operating 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 situ prestressed nearby, 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 opening pits should be dug (due to system layout flexibility, often using natural low-lying position within the permissible range set anchor, thus appropriate to reduce the orifice pit dug). The system is similar spray anchor and soil nailing wall and other surface slope system on the role of the principle, but because of the flexible features enable the system to be delivered locally concentrated loads evenly to give full play to the surrounding protective capacity of the entire system, ie the whole local Loaded effect, so that the system can withstand greater loads and reduce single bolt anchoring force requirements. In addition, due to the openness of the system, groundwater can freely excreted, to avoid the problems caused by rising groundwater slope instability caused by the pressure of the system in addition to the contribution to the stability of the slope has some outside, while inhibition of the slope suffer further weathering and erosion, and the morphology of the slope, no special requirements, does not destroy and change the slope of the original topography and vegetation growth conditions, characterized by its openness and to subsequent or conditional green artificial slope when needed in the future to retain the necessary conditions , green plants can grow freely in its open space, the role of the solid earth and slope protection plant root system became one, thus inhibiting the slope destruction and soil erosion, which in turn protects the slope topography and vegetation, to achieve the most Best of slope protection and environmental protection projects.
