Description
Technical Field
The utility model relates to a keep off snow equipment technical field, more specifically the utility model relates to a foldable snow net that keeps off that says so.
Background
Wind blowing snow is one of the common disasters in winter and spring in northern cold areas, commonly called 'Baimafeng', namely, the strong wind carries the snow. When the wind blows snow to meet obstacles, the wind speed is reduced, the snow clamping capacity is reduced, and the snow is deposited and accumulated more and more. When the wind blows snow to meet the road, if the wind direction is parallel to the road direction, the wind blows the snow and can not be deposited on the road, and the damage can not be caused; if the wind direction is not parallel to the road trend, the road becomes a barrier for blocking wind and blowing snow, the snow starts to deposit on the windward side of the road, and the more the snow is accumulated, the whole road is finally covered, and the traffic jam is caused. In winter and spring in northern cold regions, the wind directions blown by wind are mostly west wind, northwest wind and north wind, and the wind directions often swing back and forth, so that the condition that the wind directions are parallel to the road is rare, the wind directions are not parallel to the trend of the road in most cases, and particularly when the road is basically vertical to the main wind direction, snow is deposited on the road most quickly and most harmfully.
In order to avoid inconvenience brought by excessive wind and snow for traffic trips and people's lives, the existing snow retaining equipment comprises a snow retaining wall, a snow retaining fence, a snow retaining net and the like, wherein the snow retaining wall is mostly of a rammed earth, dry masonry or paddle masonry structure, the height of the snow retaining wall is generally more than 1m, and although the snow retaining effect can be achieved to a certain extent, the construction of the snow retaining wall has the defects of time and labor waste; the snow-blocking fence is of a metal net structure, the height of the snow-blocking fence is generally about 3-4 m, a metal upright is required to be arranged every 2-4 m, the metal upright needs a firm concrete foundation to ensure that the snow-blocking fence is not blown down by wind, and the snow-blocking fence has the defects of time and labor waste in construction; current fender snow net is mostly plastics network structure, highly generally about 1 ~ 1.5m, and a concrete stand need be established to every 3 ~ 6m, and the stand needs to bury deeply in order to guarantee not blown down by wind in the soil, though the construction is less time-saving more laborsaving for keeping off the snow wall and keeping off the snow fence, but concrete stand weight is great, also has hard shortcoming during on-the-spot transport and installation, and plastics material also has the risk of polluted environment moreover. Moreover, because keep off the snow fence and keep off the snow net and be the straight formula and lay, its stability relies on the fastness of stand completely, consequently makes to keep off the snow fence and keep off the snow net and have the comparatively bulky shortcoming of stand and stand basis, and it is hard to have caused to waste time and labor when carrying out on-the-spot transport and installation to it, and when the stand was out of repair for a long time, its fastness can show the decline moreover, very easily is blown down by wind, has great potential safety hazard.
Therefore, it is an urgent need to solve the problems of the prior art to provide a foldable snow-blocking net which is light in weight, convenient to transport and transport, time-saving and labor-saving to install, good in structural stability, less in ground surface disturbance, large in snow-blocking range and high in snow-blocking efficiency.
