Abstract: Protective barrier for snowstorms, for installation near communication routes in order to prevent the accumulation of snow or sand on the road. The barrier is formed by joining several screens made of a set of blades that are arranged horizontally, superposed on one another at regular distances, joined with vertical posts by anchoring their ends to several rectangular plates that are inserted in the vertical post using a ring on the plate.

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.
