ABSTRACT:
Impact absorbing assembly for slope protection systems, fitted in the containment and protection screens to guard against stones or other bodies landsliding, comprising two cables arranged in the form of loops, each being cased in a “U” shaped tube. The cables are interlaced or arranged in parallel, the loops being fastened together in their upper and lower part by a clamping element compressing the tubes. The cables comprising the invention may be installed taut between the hill anchoring and the protection system, or alternatively, fitted on the mesh support cables with the posts. When an overload occurs on the containment screen, the sudden pull on the cables will force the tubes to become distorted to slide within the clamping elements, the friction leading to a dissipation of energy.
