Due to the effect of wind transport, deposition and coagulation, in snow weather, the road is likely to be buried by snow, which will affect the normal traffic, or even cause traffic disruption. At present there is no ideal anti-snow facility to prevent and solve these problems. The only solution is mechanical or manual cleaning when the road is buried by snow. However, due to the long lines, big clean-up and maintenance costs, it is difficult to fundamentally solve the problem of snow blocking road. Taking the advantage of aerodynamics and the force of wind, steel snow barrier reduces the transport and deposition of snow by blocking the snow and the wind deflector, thereby snow buried road is effectively controlled.
