Description
Technical Field
The invention relates to the technical field of snow blocking equipment, in particular to a folding snow blocking net and a layout method thereof.
Background
Wind blowing snow is one of the common disasters in winter and spring in northern cold areas, commonly called as Bai Maofeng, namely, strong wind entrains snow. When the wind blows snow to meet the obstacle, the wind speed is reduced, the snow clamping capacity is reduced, and the snow is deposited and accumulated more. When the wind blows snow to meet the road, if the wind direction is parallel to the direction of the road, the wind blows snow can not deposit on the road, and no harm is caused; if the wind direction is not parallel to the direction of the road, the road becomes an obstacle for blocking wind and blowing snow, and the snow starts to deposit on the windward side of the road, and the more accumulated snow is, the more accumulated snow finally covers the whole road, so that the damage of no pass is caused. In winter and spring in northern cold areas, most of wind directions for blowing snow are western wind, northwest wind and north wind, and the wind directions frequently swing back and forth, so that the wind directions are rarely parallel to the road, most of the wind directions are not parallel to the direction of the road, and particularly when the road is basically perpendicular to the main wind direction, the snow is most rapidly deposited on the road and the hazard is greatest.
In order to avoid inconvenience brought by overlarge wind and snow for transportation travel and life of people, the current snow blocking equipment is provided with a snow blocking wall, a snow blocking fence, a snow blocking net and the like, wherein the snow blocking wall is of a rammed earth, dry masonry or paddle masonry structure, the height of the snow blocking wall is generally more than 1m, and the construction of the snow blocking wall has the defects of time and labor waste although the snow blocking effect can be achieved to a certain extent; the snow barrier is of a metal net structure, the height is generally about 3-4 m, a metal upright post is required to be arranged every 2-4 m, a firm concrete foundation is required for the metal upright post so as to ensure that the snow barrier is not blown down by wind, and the defect that construction is time-consuming and laborious is also caused; most of the existing snow blocking nets are of plastic net structures, the height of each of the existing snow blocking nets is generally about 1-1.5 m, a concrete column needs to be arranged every 3-6 m, the columns need to be deeply buried in the soil to ensure that the existing snow blocking nets are not blown down by wind, although the construction is time-saving and labor-saving relative to the snow blocking wall and the snow blocking fence, the concrete columns are large in weight, and the defects of labor saving during on-site transportation and installation exist, and in addition, the plastic materials also have the risk of polluting the environment.
