Initial situation
Before 2005, the German Bundesstrasse 305 (State Road) near Berchtesgaden (Bavaria) had to be closed partially or even entirely in winter. Icicles up to five meters long and one meter wide fell onto the road and endangered the traffic. For safety reasons, the road maintenance department checked the section several times a day. This effort prompted the authorities to look for a cost-effective solution.
Description
Hinged supports guide the suspension cables. As a result, breaking ice masses fall behind the mesh and not onto the road.
Moreover, the ice «grows» through the network. When the ice detaches from the ground, it causes a considerable strain on the protective drape.
Already after the first hard winter 2005/2006 with extreme ice build-up, the authorities' feedback was very positive. In the secured area, ice break-offs no longer endanger traffic. The ice drape proves its effectiveness at high ice formation and also when ice masses that have grown through the mesh detach from the ground.
A total of 1'200 m² were secured, the maximum slope height is 30 m, slope inclination 70 ° - 90 °.
