ている。2. Description of the Related Art In Japan, a cold air mass blows out of the continent in winter, and there are many opportunities to be hit by wind and snow, and there is snow cover over a wide area of the country, and if a strong wind blows during snowfall, The snow that has fallen on the ground flies and it can be a snowstorm that makes it difficult to secure visibility, so it is important to maintain the city's functions and traffic by removing snow and removing roads and passages. Securing visibility and preventing snowfall are important issues.

There are various facilities such as windbreak forests, gutters for snowstorm removal, tunnels for snowstorm removal and fences for snowstorm protection to protect against obstacles called whiteouts that cause loss of sight. The wider the facilities in the direction, the more the ideal effect will be obtained, but in recent years it is difficult to secure land and it is difficult to install facilities with sufficient effects everywhere, Tunnel for snowstorm also requires high cost for installation, so it is often constructed only in a mountain pass where there is strong snowstorm, and it is low cost as a general facility and relatively easy to install. Snow fences are often used.

With the blowing snow, the wind and snow that is blocked by the windbreak surface is distributed in the vertical direction, and the snow that has been distributed to the lower side is combined with the snow that is heading to the lower side of the wind rectification wing plate, and partly increases the wind pressure while rectifying the snow The blades collide with the wing plate, are guided and flow as a floor flow that is blown onto the road surface such as a road or a passage targeted for windbreak snow, so as to suppress snow accumulation on the road surface. While increasing the wind pressure, the snow is passed as a ceiling flow that straddles the upper side of the roads and passages subject to wind and snow, and the snow covered on the road surface is suppressed as much as possible on the leeward side of the floor where the wind speed is weakened. It can be said that the gist has a configuration in which the snow suppression area such as a road or a passage can be widened.

For example, the upper end side may be formed in a flat plate shape inclined to the leeward side, or a plurality of flat plates inclined in the same manner may be arranged above and below, or a plurality of small louver-shaped upper and lower width plates may be used. It is also possible to arrange the wing pieces vertically, and to form each wing piece as inclined so as to guide wind and snow upward, and to form a cylindrical inner surface toward the upper side. In addition to being able to be formed in the shape of a curved arc, it is possible to form a cross-sectional shape with the upper surface bulging like the wing shape of an aircraft, and on the upper side of the wing shape in the snow that passes along the upper and lower surfaces It can also be formed to generate a negative pressure to promote the rise of the snow and snow.

するものである。As described above, according to the fence for windproof snow of the present invention, the wind and snow blocked by the windproof surface portion is distributed in the vertical direction, and the wind and snow distributed downward is transmitted to the wind and snow rectifying blades located on the lower side. Blows and joins the colliding wind and snow, is guided on the road surface such as roads and passages while increasing the wind pressure, passes as a blowing floor flow, suppresses snow accumulation on the road surface, and The sorted wind and snow pushes the wind and snow that passes above the windbreak fence upward, and passes as a ceiling flow that straddles the upper side of the road or passage while increasing the wind pressure. On the downstream side of the wind and snow, a vortex is generated, and the ceiling flow is pushed up diagonally upward.Furthermore, the stormy snow that has become stalled by the vortex is also sucked into the floor surface while falling along with the snow particles,
As it passes through while being sprayed on the road surface, it enables windproof snow over a wide area, which was impossible with conventional windbreak snow fences, and it is sufficient even on roads with multiple lanes It has an excellent feature that it realizes smooth blowing of snow particles, and also prevents snow accumulation and wind pits around the fence, so that the ventilation state at the time of installation can be secured for a long time.
