AVALANCHE-PROTECTED GALLERY-SPRINGBOARD

摘要

The invention relates to construction, in particular to structures protecting railway or motor road areas from rock collapses, snow avalanches or mud flows in a mountain terrain. The invention is aimed at increasing efficiency of avalanche quenching and kicking-off thereof and dynamic stability of an avalanche-protected gallery-springboard. The avalanche-protected gallery-springboard is located at an avalanche-hazard slope above railway or motor road areas to be protected and comprises a C-shaped support wall mounted on a foundation facing by its concave part towards the slope, the wall edge rests on a flooring made as a back slab and covered with a vibrated insulating layer and a semi-cylindrical springboard mounted on the flooring back slab along the plane of the support wall edge.
