STUDY OF SNOW PROTECTION INSTALLATIONS

UNTERSUCHUNG AN SCHNEESCHUTZANLAGEN

RECENTLY INCREASING NUMBERS OF SNOW FENCES MADE OF METAL OR PLASTICS HAVE COME ONTO THE MARKET, AND THESE ARE INTENDED TO REPLACE THE CONVENTIONAL HEAVY SNOW FENCES MADE OF WOOD. THE NEW, LIGHTWEIGHT FENCES HAVE CONSIDERABLE ADVANTAGES WITH RESPECT TO INSTALLATION, TRANSPORT AND STORAGE. SINCE THE MOST IMPORTANT ASPECT OF THESE FENCES IS TO HOLD BACK SNOW, COMPARATIVE STUDIES ARE TO BE CARRIED OUT TO CHECK THIS ASPECT OF THE NEWER FENCES, WHICH ARE SUPPLIED IN VARIOUS MATERIALS AND SHAPES. THE MATERIAL RESISTANCE TO STRESS BY WEATHERING (WIND, SUN, RAIN, TEMPERATURE) AND PRESSURE OF SNOW, AND DURABILITY, AFFECTED BY TRANSPORT, INSTALLATION AND DISMANTLING ARE ALSO TO BE EXAMINED. IN ORDER TO OBTAIN DATA ON ECONOMIC JUSTIFICATION, STUDIES ARE ALSO REQUIRED ON TIMES TAKEN TO INSTALL AND DISMANTLE THE FENCES, THEIR WEIGHT, AND SPACE REQUIRED FOR STORAGE. THE STUDIES ARE TO BE CARRIED OUT WITH THE CO-OPERATION OF THE BAVARIAN CONSTRUCTION AUTHORITIES, THE MUNICH MOTORWAY DIRECTORATE AND THE TRAUNSTEIN ROAD CONSTRUCTION OFFICE AT SUITABLE POINTS ON THE MUNICH-SALZBURG MOTORWAY AND ON MAIN ROADS, AND IS TO LAST 3 - 4 YEARS DEPENDING ON SNOW CONDITIONS.
