Snow mesh fence

It is a combined fence for avalanche prevention and rockfall protection.

This is a suspended avalanche prevention fence that holds the fence surface with pillars and anchors. Due to its flexible structure, it can be installed not only on shaped slopes but also on natural slopes. It is mainly suitable for slopes with a snow depth of 4 meters or more and prevents both "full-depth avalanches" and "surface avalanches." - It can be used not only as an avalanche prevention fence but also as a rockfall protection fence, making it ideal for slope measures in snowy areas. - It features a lightweight and simple structure, allowing for short construction periods and cost reductions in installation expenses. - A full-scale model (with a pillar spacing of 4.5m and a length of 13.5m) underwent a full-scale loading test assuming a snow depth equivalent to 3m, confirming its load-bearing performance. (Equivalent to a snow depth of 3.0m loading ● resultant force 50.605kN/m) - A heavy weight impact test was conducted using a full-scale model (with a pillar spacing of 3m and a length of 9m), confirming that it retains its energy capture function. (Based on the "Rockfall Mitigation Handbook (December 2017)" - impact energy ● 116kJ, impact speed ● 25.0m/sec, weight of the heavy weight ● 0.33t)
