Highway sand prevention method in high wind energy area

Abstract

The invention relates to the technical field of wind and sand prevention and control, and provides a high wind energy area road sand prevention method which comprises the steps that a sand blocking belt, a sand fixing belt and a sand conveying belt are sequentially arranged on the windward side of a roadbed of a road in the wind and sand flow leading direction, the sand blocking belt and the sand fixing belt are spaced, and the sand conveying belt is arranged adjacent to the roadbed and connected with the sand fixing belt; the sand blocking belt, the sand fixing belt and the sand conveying belt are sequentially arranged from high to low. The sand prevention effect can be improved, sand accumulation bodies are effectively prevented from gathering and invading the highway pavement, and the smoothness of the road is guaranteed; in addition, a large amount of accumulated sand does not need to be cleaned in the using process, the middle and later maintenance cost is low, the sustainable protection performance is high, and the service life is long.

Description

Technical field [0001] The present invention relates to a sand control techniques, and more particularly relates to a method for high wind road sand zone. Background technique [0002] Drift potential high wind areas generally more than 400VU, road protection system related technologies commonly used sand fixation grid, way more single sand, and after prolonged use can produce a large volume of sand body, when the body is greater than the height of accumulated sand after the scope of the system will lead to sand sand system failure, resulting in accumulated sand sand body system will forward the devastation, and the product is easy to gather sand body invasion road surface, seriously affecting the patency of the road. Inventive content [0003] The present invention provides a method of road sand high wind area, can increase the effect of sand, effectively prevent the invasion of blown sand body accumulation road surface to ensure the patency of the road; and the invention in th...

AI Technical Summary

Problems solved by technology

[0002] The sand transport potential in high wind energy areas generally exceeds 400VU. The highway protection system of related technologies usually adopts sand-fixing grids, and the sand prevention method is relatively simple, and large sand accumulation bodies will be generated after long-term use. When the height of the sand accumulation body is greater than The protection range of the sand control system will lead to the failure of the sand control system, and the forward movement of the sand accumulation body will cause devastating damage to the sand prevention system, and the sand accumulation body is easy to gather and invade the road surface, seriously affecting the smoothness of the road
