According to Liu Qingkuan, the Genting stadium group in Zhangjiakou competition area is responsible for most of the free>

Previously, the windproof nets for the skiing competition venues of the Winter Olympics were all produced and installed by European companies.

According to Liu Qingkuan, the International Snow Federation has strict requirements on a number of indicators of the windbreak net for ski competitions, and the design must be based on wind shielding efficiency, light transmission, color, strength and other aspects

After solving the parameter problem, the visual effect of the windbreak net becomes a problem again

Liu Qingkuan said that the high-density polyethylene windproof net is about 4 mm thick, and the internal three-dimensional space structure is complex.

　　In addition, in order to ensure the low temperature resistance of the tensioning power system, the driving device is also equipped with a rapid low temperature heating device to ensure that the tensioning and recycling operations can be quickly started at low temperature

　　On the aerial skills track of Genting Ski Resort, Xu Mengtao and Qi Guangpu contributed two gold medals to China respectively, and the mixed team of Xu Mengtao, Qi Guangpu and Jia Zongyang won a silver medal; in the U-shaped skill competition, Gu Ailing won a gold medal
