Wind shielding gravel mechanism not vertical to ground

Abstract

The invention relates to a wind shielding gravel mechanism not vertical to the ground. The wind shielding gravel mechanism comprises a base, a wind shielding gravel structure installed on the base; in the movement direction of wind, the wind shielding gravel structure is in an arrangement with an inclined angle of 30-80 degrees with the installment plane of the base; in addition, the wind shielding gravel structure is provided with a plurality of through holes with aperture ratio of 20-80%, at least a part of windward side of the wind shielding gravel structure is a curve structure. The wind shielding gravel structure not vertical to ground can change wind direction on the ground on the basis of an aerodynamic principle and enables wind to be output in direction parallel to the installment direction of the wind shielding gravel mechanism, and thus corrosion phenomenon can be avoided effectively; in addition, due to the change of wind direction and shielding of the wind shielding gravel mechanism, wind power in the wind shielding gravel mechanism is reduced obviously, and thus the wind shielding gravel mechanism can be used for reducing the sand carrying capacity of wind can be effectively weakened, and the damage of sand flow to railways, highways and other traffic facilities can be further prevented.

Description

technical field [0001] The invention relates to a wind-sand retaining wall structure, in particular to a wind-sand-stone net wall on a non-vertical ground. Background technique [0002] Existing wind-sand retaining wall structure 10 overwhelming majority all is installed vertically to the ground, as figure 1 shown. [0003] This kind of structure is convenient for design and installation. However, for some areas with large amount of wind and sand and fast wind speed, such as the northwestern part of China, the maximum wind speed can reach more than 30 s / m. Therefore, the wind and sand retaining wall structure or windbreak wall structure installed vertically is very easy to form turbulent flow due to the wind close to the surface under the condition of wall barrier, and, over time, erosion will occur. [0004] After the erosion occurs, the sand-fixing body for windbreaks is prone to wind and sand flow directly blowing into the windshield area from the ground. Thereby more ...

Problems solved by technology

Therefore, it is difficult for the existing upright anti-wind and sand retaining wall to achieve the ideal anti-wind and sand effect in areas with large amount of wind and sand and fast wind speed. At the same time, it will also cause waste of original equipment and loss of manpower and material resources in the secondary installation process.
