METHOD TO PROTECT ROADS AGAINST SNOW AVALANCHES AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC E01F7/04 

FIELD: construction.

SUBSTANCE: method includes lowering of snow of subcritical mass into an accumulating groove, on the bottom of which they lay pipes in parallel to each other, inside of which heating elements are installed, and whenever an avalanche collapses, they determine the subcritical mass with a weight sensor, snow avalanche heating is started in automatic mode with subsequent drainage of melted mass along the pipes. The subcritical mass is determined by gravity of snow avalanche equal to at least 170 kg/m². The technical result is also achieved with a device comprising an accumulating groove, which is equipped with pipes, heating elements and a weight sensor, besides, the latter is connected to heating elements and source of power supply.

EFFECT: reduced labour intensiveness, higher efficiency, increased safety and reduced prime cost for protection of roads from snow avalanches.
