Product Description

Passive protection is by the cable network, ring network, (need to intercept a small piece of rock fall when additional layer of wire grid), fixed system (anchor rod, anchor rope, base and support rope) reduced pressure ring and steel column four main parts.Steel columns and steel wire rope connection that constitute a whole, to form the protection surface protection, so as to prevent collapse of rock soil mass drop, slope protection effect.
The material
Wire rope net, rope and reduced pressure ring.
structure
Mesh wire rope or ring network (need to intercept a small piece of rock fall when additional layer of wire grid), fixed system (anchor rod, anchor rope, rope base and support), reduced pressure ring and steel column four main parts.
Product features
System of flexible and intercept strength enough to absorb and disperse rock fall expected impact kinetic energy, and energy dissipation design and adopt the system of further improve impact resistant ability. Compared with the rigid intercept and build by laying bricks or stones slurry retaining wall, changed the original construction technology, reduce time and money to get.
Commonly used specifications:
[steel column (spacing of *0 m), *0 with energy dissipation ring double support line *6 and *0 *6 "people" glyph on the anchor rope (each across six energy dissipation loop), *0 *6 lateral tensile anchor rope () belay devices designed, cardiac / *8/**0/4 * 5 ㎡ wire rope net, *0 8 suture line, grille net]
Product features:
With several strands of wire and form a circular by the socket of the net.Its role is to intercept rockfall protection energy is commonly **0 kj - ***0 kj
Installation steps
(1) the SNS flexible slope fence installation steps according to the design and combined with the actual topography measurement location of steel column and anchor foundation.The pay-off length should be more than the length of design system about 3 ~ 8%, the terrain ups and downs is bigger, system layout difficult along the same contour line layout take upper limit (8%);In relatively flat terrain rules, system layout can basically in the same contour decorate along a straight line when removed (3%);On this basis, the column spacing can be adjusted for design spacing *0% shortened or widen the scope.(2) the foundation pit excavation (not the overburden layer thickness, when excavation and has yet to reach the design depth to bedrock, the anchor hole position in the foundation pit drill bolt hole, stay after grouting anchor rod inserted into the bedrock and perfusion upper foundation concrete).
(3) embedded anchor and perfusion foundation concrete (on rock foundation, 2, 3, process should be hole drilling anchor and anchor installation, the concrete foundation, also after perfusion foundation concrete drilling anchor installation).
(4) the base installation: the base set into the anchor bolt and nut and tighten.
(5) on the steel column and anchor rope installation
(6) the installation of the lateral tensile anchor rope: ditto installation method of anchor rope, only after pulling anchor rope is installed on.
(7) on the support line installation
(8) the support line installation
(9) the installation of steel rope net
(*0) steel wire rope mesh grille installation
