Description

  The present invention relates to a road surface freezing prevention method and apparatus for preventing freezing by uniformly spraying an antifreezing agent on road surfaces of roads such as cold regions and mountainous regions.

  In cold areas and mountainous areas in winter, road surfaces freeze, or snow accumulates, causing slippage in driving of automobiles and the like, resulting in frequent traffic accidents. In particular, automobiles are slippery on slopes and sharp curves, causing contact accidents and rear-end collisions.

Therefore, pipes are buried on the road surface at the required location, and the liquid antifreeze agent is pumped by the electric pump installed on the side of the road to exude the antifreeze agent on the road surface to prevent freezing. It has been proposed that an antifreezing agent spraying device is installed on the side to detect the outside air temperature, and a granular antifreezing agent is sprayed through a rotating disk type spraying mechanism to prevent freezing.

  However, with the former, the tolerance of the nozzle installation location is wide and remote spraying is possible, and the drug oozes out from the road surface, so the efficiency of the drug is good. It was expensive and easily affected by the ruins of the car, and the drug was easily diluted and the effect was not sustained.

  In the latter case, primary power construction and civil engineering work are not required, and the equipment cost is low, and since the granular chemical spraying is simple, the equipment is simple because the chemical is granular, but the remote spraying is not possible. Since it was granular, it was easily affected by the wind and could not be spread evenly.

  For example, when a liquid antifreezing agent is pressurized and sprayed, if the nozzle portion is in a diffused state as shown in FIG. 11, it can be sprayed in a fan shape, but the sprayed state is dense near the spraying device, and the sprayed state is far away. Becomes thinner and cannot be applied uniformly as expected. In addition, when the nozzle portion is in the throttle state, it can be sprayed far away as shown by the alternate long and short dash line in the figure, but it cannot be sprayed uniformly over a wide range because it has a narrow bat shape. It was.
