SNS Slope 1770MPA Rockfall Protection Steel Wire Mesh Fence Corrosion Resisting

SNS slope protection fence System Rockfall protection steel wire mesh fence High Tensile


1. Product description

Simple Introduction
The slope protection netis called SNS slope protection net,there are Active Protection System and passive Protection System
1.
Active Protection System is mainly made of various types of flexible steel wire mesh grille, high-strength steel wire rope net or TECCO to cover or wrap in protective slope or dangerous stone, to limit the slope rock soil from weathering or flaking or collapsing (reinforcement effect), or (maintenance effect).
SNS Active Protection System: using high-strength galvanized steel wire rope, steel wire mesh, not less than embalmed AB discipline, the corrosion life can be up to 30 50 years based on different environmental conditions, mainly to prevent from the slope failure, potential danger from falling rocks slope . there will form a (4.5m *4.5m) square pattern with the aside criss-cross the 16 # and 12 # supporting rope according to the slope type , and pre-tensioning with 4 * 4M of Active Net using suture rope, so that will form certain preload pressure to the lope, to enhance the stability of the rock, prevent rockfall occurring, the system does not affect the normal excretion of groundwater.
Composition (Technical Specifications):
1. wire rope anchor
the raw material should be 16 # steel wire rope, also can be steel wire; and anchor bolt aperture and length, tensile strength not less than 80KN, the remaining anchor tensile strength not less than 50KN. The length should be determined based on the calculation, and not less than 2 meters. Steel rod anchor bolt aperture should be larger than the rod diameter 12mm; double-strand steel wire rope anchor aperture should be more than twice the steel wire diameter 10mm.



2. The steel wire rope mesh:
using KO / 08/300-type wire rope , 4m * 4m per piece, when necessary, you can add another single steel wire rope net at the edges, if there are a large volume
of dangerous rocks heap, using double-reinforced steel wire rope net can be considered, the rope anchor tensile strength not less than 104KN,



3. The support rope;
the transversal support rope diameter should be 16 # steel wire rope, longitudinal support rope should be 12 # steel wire rope, the actual length of each support rope should be 1m longer than the rope mesh length,to fix the wire rope anchor,.when the support rope laying length L <= 10M, 10m <l <30m, or L> 30m, at the both ends of each, there will be two, three, or four corresponding fixed rope to fix it.



4. Suture wire rope;
suture wire rope diameter should be 8 # , one piece steel wire rope mesh is stitched by one suture wire rope. both end of the suture wire rope are fixed with two 8 # rope clip.
5. Steel wire mesh/ grille under the wire rope mesh GPS1 and GPS2-type active fence net, should put a wire rope grid under the wire rope mesh, wire diameter 2.2mm galvanized steel wire mesh of the wire grid 50 * 50mm, Georgia The grid is made of 1.2mm wire banding

2. Passive slope protection systems
Passive slope protection systems are those do not affect the process of the rock detachment, but rather focus on the containing and intercepting falling and sliding debris, therefore averting danger to the infrastructures and its users. Passive protection systems includes simple drapery systems, rockfall protection barriers, rockfall protection embankment.
