The roads and railway go through desert and Gobi areas are facing poor natural conditions. Traffic is frequently suspended due to the strong wind and sand. People plant trees, shrub and grass along the road to prevent the wind and fix the sand. But due to drought and water shortage, the survival rate of these plants is low and the cost of maintenance is big. It is difficult to solve the problem of sand resistance and sand damage fundamentally.
Due to the effect of wind transport, deposition and coagulation, in desert area, the road and the railway are likely to be buried by sand, which will affect the normal traffic, or even cause traffic disruption.
Taking the advantage of aerodynamics and the force of wind, steel sand barrier reduces the capability of wind transport and deposition by blocking the sand and deflecting the wind, thereby the road is effectively prevented from sand burial.
