Active Protection System is mainly of various types of flexible steel wire rope net covering wrapped in protective slope or rock needed to limit the slope rock weathering or damage to soil and rock collapse (reinforcement effect), or the rockfall control movement (envelope effect) material within a certain range: steel wire rope, ordinary steel grille (often called wire grill) and TECCO high strength steel wire mesh. Structure: the first two by wire rope anchor and / or support rope fixed way, the latter through reinforcement (can be prestressed) and / or wire rope anchor (when using edge support rope), dedicated anchor plate and, if necessary edge support rope fixed way. Product Features: Similar to the role of the principle spray anchor and soil nailing wall and other surface slope system, but because of the flexible features make the system both locally concentrated load to the surrounding material: steel wire rope, ordinary steel grille (often called wire grill ) and high-strength steel wire mesh uniform TECCO delivered in full protective capacity of the entire system, ie locally under load, the overall effect, so that the system can withstand greater loads and reduce single bolt anchoring force requirements. Usage: open systems, groundwater can freely excreted, to avoid the problems caused by rising groundwater slope instability caused by pressure; the system in addition to the contribution to the stability of the slope has some outside, while inhibition of 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 to subsequent or future conditional and implement artificial slope when you need to retain the necessary green 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 topography and slope vegetation to achieve Best of slope protection and environmental protection purposes. [1] safety net simple types: Edge (or on the edge) anchor rope + + support rope stitch rope (D0 / 08/300 steel anchor rope + + up and down up and down along the edge (or horizontal) support rope) edge (or on along) support rope wire rope anchor + + suture rope (D0 / 08/300 + up and down along the steel rope anchor + down along (or horizontal) support rope) general model: system support rope wire rope anchor + + suture rope, orifice pits + tension [or edge (along) the anchor (2-4m cable bolt from 4.5m) + vertical and horizontal support rope (2-∮16) + wire rope (◇ 08/300/4 * 4 m) + suture rope (∮8)] safety net structure configuration: steel wire rope, wire rope anchor, support rope, stitching wire, steel wire mesh grille.
