Description

  The present invention relates to a road blizzard guidance fence effective for ensuring visibility of a driver from a blizzard that easily occurs on a road, particularly a wide road such as a highway.

In cold snowy areas, strong winds cause snowstorms on the road, which hinders the driver's view and obstructs traffic and causes traffic accidents. Therefore, conventionally, a blow-off type snow fence (see Patent Document 1), a blow-off type snow fence (see Patent Document 2), and a snowdrift type snow fence are set up along the shoulder of the road, and there is a blizzard on the road. Suppressing the occurrence is performed. In particular, it has been attempted to reduce the driver's visibility disturbance by standing a snow-stop type snow fence on the shoulder of the road and guiding the snowstorm along the fence. In addition, snow shelters are installed in places where storms are likely to occur.

  As described above, the conventional snow fence is erected along the road, and is effective in suppressing snow blowing from the side of the road. However, the blow-off type snow fence and the snowdrift type snow fence cannot exert any suppression effect on the ground snowstorm running on the road. Also, the method of inducing snowstorm by standing a snowstop fence on the shoulder of the road can only reduce the driver's visibility trouble, and is not very effective in suppressing the snowstorm.

  Furthermore, the snow shelter does not require summertime, it has the disadvantage of damaging the landscape, the high cost of manufacturing and installation costs, the problem that the installation road cannot be connected in the middle of the shelter, and the driver feels pressured There are a number of drawbacks and problems, such as giving.

  The present invention has been made in view of the above-described unsolved problems of the prior art, and that the snowstorm is due to the seasonal wind, and that the direction of spraying is almost constant every year in the region. Providing road blizzard guidance fences that ensure the visibility of the driver and enable safe driving by effectively guiding the blizzard flowing along wide roads such as high-standard roads and national roads. Objective.

The means of the present invention configured to solve the above-described problem is configured by a vertical column and a beam material in a substantially bowl shape, and a base that stands across a road in a substantially orthogonal state, and a snowstorm on the road Are arranged in the beam material in a state of facing the blowing direction, and includes a plurality of snow blowing guide plates for guiding the blizzard flowing along the road upward and flowing backward .

  And the said snowstorm guide plate is good to form in the substantially flat S shape where the upper end side curves along the blowing direction of snowstorm, and the lower end side curves toward the blowing direction of snowstorm.

  The plurality of snow blowing guide plates may be arranged with a blow-off space having a predetermined interval.

  Furthermore, it is preferable that the snow blowing guide plate can be angle-set in the front-rear direction.

  Furthermore, the snow blowing guide plate may be capable of setting an angle in the left-right direction.

Since the present invention is configured as described in detail above, the following effects can be obtained.
(1) On wide roads such as highways, the snowstorm that flows along the road is guided upward to flow backwards, so that the driver's visibility can be ensured and safe driving Can be realized.
(2) Since the snowstorm guide plate is formed in a substantially flat S-shape in which the upper end side is curved along the blowing direction of the snowstorm and the lower end side is curved toward the blowing direction of the snowstorm, the snowstorm is smoothly guided upward, Can flow backwards.
(3) Since the plurality of snowstorm guide plates are arranged so as to allow a part of the ground snowstorm to escape backward by arranging the atrium spaces having predetermined intervals, the base that supports the plurality of snowstorm guide plates Therefore, it is not necessary to give the substrate excessive strength.
(4) Since the snow blowing guide plate can set the angle in the front-rear direction, the snow blowing can be effectively guided according to the wind direction, the terrain condition, the strength of the snow blowing, etc.
(5) Since the snowstorm guide plate can set the angle in the left-right direction, the snowstorm can be promptly guided outside the road according to the wind direction, the terrain condition, the strength of the snowstorm, etc. in the area where the snowstorm guide plate is installed.
