FIELD: construction.
SUBSTANCE: device includes gratings of strong materials which are installed on the road, covered with ice or snow. Equipment of grading elements with drives, allowing the gradings to carry out translational back motion is a new characteristic. This motion allows to move the falling snow under the gratings.
EFFECT: use of the proposed invention will permit to reduce the impact of snowfall and ice on the transport system, reduce the negative influence of anti-icing reagents and improve safety of vehicular traffic and pedestrians.
