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.

[0004] A windbreak snow fence widely used as a simple facility as described above is called a blow-off fence, and utilizes the fact that the wind speed is increased by passing through a gap formed in the fence, thereby removing snow on the road. There is a structure that blows away, and a specific structure thereof is as shown in a side view of the use state of the conventional windbreak snow fence in FIG. A plurality of upper and lower wind rectifying blades 4, 4,... Are stretched in a bridging manner between the support portions 2, 2 erected at predetermined intervals around the windward boundary of the wind rectifier. The wing plates 4, 4, ... are inclined at a predetermined angle so that they face downward from the windward side to the leeward side, and are fixed. The wind and snow to be blown is rectified and guided toward the road surface to remove the snow on the road surface. Although it is configured to blow off, this windproof snow fence 1 In the case of the above, the wind and snow passing through the upper part tends to fall to a relatively close place, and as shown in FIG. 8, on the road 9 having two lanes, snow particles are accumulated in the lane located on the remote side, It has been the present situation that snowfall and the snowstorm phenomenon are caused, and a sufficient windproof snow effect cannot be obtained.

As described above, according to the present invention, it is impossible to perform effective windbreak snow over the entire width of a wide road having a plurality of lanes with the conventional windbreak snow fence, and the wintertime when wind and snow frequently occur is impossible. It is difficult to secure good traffic during the period, which not only reduces city functions, but also makes it impossible to secure sufficient visibility and safety. In order to do this, we will start developing and researching it quickly, trial and error for a long time and a lot of trial production,
As a result of repeating experiments, we finally succeeded in realizing a windbreak snow fence with a new structure that can solve those problems. The configuration will be described in detail together with the embodiment.

[0007] Further, the windproof snow fence of this basic configuration is
In other words, pillars are erected at predetermined intervals around the windward boundary of a road or a passage subject to wind and snow, and these pillars are adjacent to each other. The windproof surface portion of a predetermined vertical width, a single or a plurality of the windshield surface portion is stretched in a bridging manner, and between the strut portions from the lower end edge of the windproof surface portion, the road and the windproof snow target, Wind and snow rectifying blades inclined downward toward the road surface such as a passage, or one or a plurality of upper and lower tiers combined at appropriate intervals and stretched in a bridge form,
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.

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.

When the parts are replaced, the parts can be easily replaced, and each part including the column can be disassembled into dimensions and weights that can be manually transported, installed and removed, or can be folded and / or reduced. By doing
Until now, roads and passages had to be partially closed before and after the snowfall season to perform large-scale installation work using large cranes, etc. The work can be installed efficiently and economically mainly by the manual work by the worker who uses the as a supplement.

In particular, the fence 1 for windproof snow described in the embodiment
The windbreak surface section 3 is formed from a windbreak net to secure a good view and visibility, reduce the feeling of blockage, secure traffic safety, and form the display portions 34, 34 for patterns, characters, etc. to improve the appearance. It can also function as a display board that can send a message to people passing by, such as calling for traffic safety, etc.
By combining a guide plate portion 6 whose upper edge side is inclined upward in the leeward direction between the upper ends in a bridging manner, the windbreak surface portion 3 blocks the rise and guides the rising wind and snow upward,
The ceiling flow 8 can be made to jump to the remote side, and the effect of preventing a wide area of snow accumulation and snow particle accumulation that has been impossible with the conventional structure can be exhibited.
