Combined assembly of wind-shield wall for preventing and controlling sand

The invention discloses a wind-shield wall for preventing and controlling sand, which is designed for Siberia cold wind and sand from Mongolia invading China, thick sand grains in the sand dust are concentrated in the space of 50 meters below and the cold air is sunk. In the boundary line of China and Mongolia, a sand-preventing wind-shield wall with height of 60 meters is built from the east to the west. A second wind-shield wall with height of 60 meters is built at the place with 20 kilometers distance to the first wind-shield wall. A third wind-shield wall is built at the north with 20 kilometers distance to Beijing. Meanwhile, the patent 'Anti-dust Concrete Buckle Plate' in review and planting are carried out. Therefore the sand-prevention takes effect immediately and quickly, the effect of long-term sand prevention and garden type preventing effect are achieved completely. The invasion force and the intensity of the Siberia cold wind are effectively released, abundant wind power is obtained. The conclusi
