Active Protection Active Protection System is based wire rope wrapped cover all types of flexible net in the desired protective slope or rock, to limit the slope rock weathering or damage to soil and rock collapse (reinforcement effect), or rockfall control within a certain range of motion (envelope effect). 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 edge support when necessary rope fixed way. With high flexibility, high protection strength, easy spreading. Adapt to any terrain slope, the installer standardized and systematic. The system uses die-cutting of installation, short duration, low construction costs. Special manufacturing processes and high corrosion preventive materials technology systems, determines the ultra life of the system. Systems engineering team can affect the environment to a minimum, the protection zone can adequately protect the soil, rock solid, easy to artificial green, environmentally friendly. Similar spray anchor and soil nailing wall and other surface slope system on the role of principle, 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 TECCO High strength steel grille guard uniform transfer to full 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. System openness, groundwater can freely excreted avoid problems due to rising slope instability caused by groundwater pressure; the system in addition to the contribution to the stability of the slope has some outside, while inhibition of slope subjected to further weathering and erosion and morphological characteristics 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 the subsequent and artificial slope or conditional green retain the necessary conditions needed in the future, 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 best slope protection and environmental protection purposes. 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) general model: system support wire rope anchor + + suture rope rope, opening the pit + tension [or edge (along) the anchor (anchor 2-4m cable from 4.5m) + vertical and horizontal support rope (2-∮16) + wire rope (◇ 08 / 300/4 * 4 m) + suture rope (∮8)]
