A few days ago, the windproof wall was unveiled in the Yunding Ski Park in the Zhangjiakou Competition Area of the Beijing Winter Olympics. The establishment of the windproof wall can effectively reduce the interference of high winds on athletes and ensure the normal operation of the event. It is reported that the windproof wall is composed of a snow-white net and a tower, with high tensile strength, and the windproof net is convenient to open and close under the anti-low temperature power control system, which can reduce the wind speed of more than 10 m/s in the sports space to 3.5 m/s.
