Bun nets Description: Active Protection Active Protection System is a wire rope wrapped mainly covering 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 the rockfall control within a certain range of motion (envelope effect). Bun nets constructed: 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), as well as special anchor plate fixation edge support rope when necessary. Bun network characteristics: 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. Bun nets purposes: 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 artificial slope greening implemented retained 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 when needed 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 topography and slope vegetation achieve optimum 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) (or on the edge) anchor rope edge + + support rope stitch rope (D0 / 08/300 steel anchor rope + down + up and down along the edge (or horizontal) support rope) general model: system support rope wire rope anchor + + suture rope tensioning orifice pit + [or edge (along) the anchor (anchor 2-4m cable from 4.5m) + vertical and horizontal support rope (∮12-∮16) + wire rope (◇ 08/300/4 * 4 m) + suture rope ( ∮8)].
