Description
Technical Field
The utility model belongs to the field of highway wind and snow disaster prevention and control, and particularly relates to a combined wind and snow prevention highway facility.
Background
Highways, in particular highways, are important traffic infrastructures, the traffic capacity of which ensures the smoothness of a region and even of the entire traffic network. However, in winter in a part of areas, because of the snow damage caused by large-scale snowfall, such as wind snow blowing, avalanche and the like, the road is often buried along the road, traffic interruption is caused, traffic accidents are easy to cause, and great trouble is caused to the economic development of the areas and the life of people.
Wind blows snow, also known as wind-snow flow, is an important component of snow damage, and is formed because when natural wind force is strong, wind blows snow on the ground to cause snow migration, and when the snow encounters obstacles or areas with changed topography (such as roads and the like), airflow is rapidly reduced or forms airflow vortex, so that wind flow in the wind-snow flow is separated from the snow flow, and accumulated sedimentation is carried out in the areas such as roads and the like to form snow. The influence of wind and snow blowing damage on road traffic is extremely large, snow particles are accumulated, so that snow is prevented from being broken, meanwhile, when wind and snow flow is strong, visibility is reduced, vision obstacles are formed, and the vision of a driver is influenced; on ice and snow roads, the sliding friction coefficient is small, the braking distance of the vehicle is long, traffic accidents are very easy to cause, and the difficulty of disaster relief work is increased due to severe traffic conditions. Particularly in high altitude mountain areas, snow can be blown by wind to form snow eaves at the ridge or local snow accumulation at the leeward slope, which becomes an induction factor of avalanche and has great influence on the transportation of mountain line highway. The mountain roads, such as the hillside roads, have more curve turning areas, so the mountain roads are more prone to flow around and accumulation, and traffic is blocked. Outlets such as highway tunnels in mountain areas are more susceptible to snow and thus cause blockage of the entire line. In summary, wind and snow disasters have a great influence on road traffic, particularly mountain road traffic.
In the existing snow protection facilities, snow protection walls, snow protection fences, snow protection forests and the like are widely applied, but the problems of low snow protection efficiency, poor durability of facilities due to environmental influence and the like are commonly existed, so that a high-efficiency highway snow protection facility is needed to solve the problem of wind and snow disasters of a highway.

The working principle and the working flow of the utility model are as follows:
When the snow and wind flow passes through the highway 1 provided with the utility model, firstly, the wind speed is reduced because of the blocking of the arc-shaped air deflector 8 and the snow blocking wall 7, and meanwhile, the flow field of the snow and wind flow is changed along the flow field direction of the concave side of the arc-shaped air deflector 8 to form vortex, and the carried part of snow particles are subject to the change of the flow field and the reduction of the wind speed can not reach the starting wind speed so as to be settled, thereby falling outside the snow blocking wall 7.
Some snow particles may still migrate with reduced wind speed, but after passing over the arcuate deflector 8, due to the disappearance of the obstacle, the wind speed changes and some snow particles settle down into the snow storage trench 6. The further snow particles encounter the barrier of the snow guard 3 and settle down in the snow guard 3 or the two side snow storage trench 6. The flow field wind speed is reduced by multiple changes, so that the starting wind speed of most snow particles cannot be achieved, and the wind and snow flow is effectively blocked. Meanwhile, as part of snow is settled in the snow storage trench 6, the inside of the snow storage trench 6 is affected by the terrain due to wind speed, and the flow field changes to form the gate way wind. Under the action of the gate wind in the snow storage trench 6, part of snow particles are blown away along the snow storage trench 6, so that excessive accumulation of the snow particles is avoided, and the influence on snow protection facilities is avoided.
Snow melt water plays an important role in regional hydrology, snow reserved in the snow storage trench 6 can be effectively utilized, and snow in other places can be stacked in the snow storage trench 6 for storage. The utility model is applicable to the prior art where it is not described.
