This EAD applies to Flexible Facing Systems for Slope Stabilization and Rock Protection, which should be made up of one or more identical functional panels placed in sequence, which permits adjusting the horizontal and vertical distance between the nails and their lengths according to the project-specific requirements. The Flexible Facing Systems for Slope Stabilization and Rock Protection are made from steel wire mesh/net to prevent and control the rolling and falling of rocks on slopes and to stabilize unstable slopes by covering them with either drape or nailed solutions.
Only the characteristics of the chain link wire mesh/spiral rope net construction products, connections and spike plates are included in this document. Upper, lower and lateral ropes and anchors and/or soil nails for fixing the chain link wire mesh/spiral rope net to the unstable slope are not covered by this EAD.
The Flexible Facing Systems according to EN 14490:2010 for Slope Stabilization and Rock Protection are made up from : a) Surface components, which has the function of absorbing the resulting driving forces and transmitting them via the system spike plate or wire ropes to the nailing or anchorage and thus to the subsoil; b) Soil / rock nails, which act as tension/shear elements and transfer the load acting from the mesh/net via the spike plate into the subsoil; c) Secondary (optional) individual parts, which have the function to fasten the mesh/net as closely as possible against the subsoil respectively fastening and reinforcing the edge areas. Chain link mesh rolls are connected together with clips while spiral rope net rolls are connected using shackles, see Figure 2b). Seamy ropes are also possible to be used.
