Abstract:
1. Impact absorbing assembly in slope protection systems having a barrier to protect against stones or other bodies breaking away from hillsides, said assembly designed to dissipate the considerable energy loads to which the protection barrier may be subjected, and adapted to be installed taut between a hill anchoring and the protection system, or to be fitted between the barrier and its support posts, said assembly comprising two “U” shaped hollow tubes, each having a pair of legs with open ends and a curve connecting said legs remote from said open ends, two cables forming independent, identical loops, each encased in one of said “U” shaped tubes and having a pair of legs extending out of said open ends of the associated tube and a curve within said curves of the tube, the encased loops being closed at the ends remote from said open ends of said tubes, said cable loops being positioned in opposing directions, and clamping elements located adjacent the open ends of the “U” shaped tubes to fit the two loops together to provide a predetermined length in the assembly between the remote ends of the legs of the cable loops, said clamping elements compressing the tubes, distorting them in their section, whereby in the event of overloads in the protection system, the tubes to are allowed to move longitudinally of said tube legs and said cable legs and resize the said predetermined length.
