Description of the Related Art Conventionally, on roads and airport runways in areas where there is a large amount of snowfall, when snow is accumulated, snow is removed to the side of the road or the side of the runway with a snowplow. Or flowing hot water on the road and the surface of the airport runway, and melting snowfall with the heat of the hot water to prevent snow accumulation. However, if the snow accumulated by the snowplow is brought to the side of the road or runway to secure the road or runway, there is a problem that the road or runway cannot be used until the snowplow has completed snow removal. When there is a lot of snow, there is a problem that the place where snow removal has been completed is covered with snow and cannot be used unless the snow is removed again. In addition, even if a method of flowing hot water on the road surface and melting snowfall with the heat of the hot water to prevent snow accumulation, when the amount of snowfall increases, partial snowmelt results due to the relationship between the discharge amount of hot water and the amount of snowfall. In some cases, there is a problem that, in cold weather, the discharge port freezes, hinders the flow of warm water, resulting in partial melting of snow, making it impossible to prevent uniform snow accumulation. Further, as described in JP-A-8-269907, a far-infrared radiation sheet and a sheet heating element are laid below the road surface, and the far-infrared radiation sheet is heated by the sheet heating element to emit far-infrared rays. It has been proposed to melt the snow. However, this method has a problem that it is not suitable for a place having a small amount of heat and a large amount of snowfall. In view of the above, the present invention has been made in consideration of the above-described problems in the related art, and has as its object to provide a snow and freezing prevention device for a road and an airport runway that can supply heat for melting snowfall on the entire road surface. Is what you do.
