Protective ring network using hot dip galvanizing process, the process can happen rockfall impact their geometry change, with a more prominent feature of the flexible ring to replace the wire rope safety net, as a basis for blocking stone network can achieve more than 3000kJ rockfall block, and can further simplify the structure of the form (such as rope and configuration support ring vacuum) to facilitate the maintenance of local repair after damage ring safety net has become a new alternative to wire rope system stopped stone network (RXI-type), achieve the replacement and upgrading of SNS passive protection systems. SNS slope protection net ring main models: RXI-025, RXI-050, RXI-075, RXI-100, RXI-150, RXI-200 and so on. Configuration: steel column (H-beam), support rope, pull anchor system, stitching wire, pressure ring, ring nets, wire mesh grille features: ring-type network system is a special branch of passive protection system, which has more than Ordinary higher strength characteristics of passive protection systems. The same applies to the buffer zone next to the building facilities of high mountains, the rock fall, flying rocks, avalanches, mudslides blocked from building facilities to avoid disaster destroyed the building facilities. Passive safety net (ring network -RXI Series) ring networks are used in diameter 3mm, the tensile strength of not less than 1770MPa high strength steel twine a few laps into the ring and socket from each other, the ring hole diameter is generally 300, 350 , 400mm. Twine bad thing according to the number of laps varies Forgetfulness good, finished size is generally 5 × 3/4/5/6 / 7m. Single ring ring network by a single wire twine from both ends of the first lap length of 100mm or more, twine made of steel or aluminum ring with a uniform distribution of fasteners in three clenched, so we ensure the ring the overall strength of the network but also beautiful and durable. Circular Fence Features: 1, can occur when the impact ring hole geometry deformation 2, showing superior flexibility characteristic 3, more powerful energy absorption capacity of 40,000, up 3000KJ achieve kinetic energy above 5 rockfall interception, greater flexibility Working Range 6, replace a smaller maintenance needs 7, mutually independent ring socket holes between 8 and partial damage repair easier and more economical
