The winter Olympics scene | windproof net is amazing, very perfect

Among the three divisions of the Beijing Winter Olympics, Yanqing and Zhangjiakou mainly hosted snow competitions. Because Yanqing and Zhangjiakou are located in mountainous areas, the snow competition venues built in these two major competition areas are particularly vulnerable to the various impacts of climate change in the mountainous areas, so the two competition areas have made careful arrangements in terms of wind protection and sun protection. Through the experience of the past few days, athletes including Sean White have praised the facilities.

In the Zhangjiakou Genting Stadium Group, 9 snow white poles and 8 flat snow white windproof nets were erected on the side of the track of aerial skills and U-shaped field skills, which allowed athletes to be as little as possible from wind interference when competing. From the appearance, this set of windproof devices seems to be no different from the general windproof net, but in fact, the material contains a lot of scientific and technological components. It is made of high-density polyethylene material, the interior has a complex three-dimensional space structure, so it has good light transmission performance, but also has a strong tensile performance, 1 meter width of the windproof net can withstand 1.2 tons of pressure, which makes its wind speed reduction performance is particularly good, 10 meters per second of high wind, after its blocking, the wind speed is reduced to 3.5 meters per second.

In addition, it also has anti-ultraviolet function, long-term exposure to the sun will not easily change color, and the surface decoration is also very beautiful, to ensure the visual effect of live TV during the game.

The wind speed in the field after the wind is almost zero, which is ideal for athletes and has won the praise of many athletes. After the U-shaped track skills competition, sean White, a men's snowboarder and three-time Winter Olympic champion, said: "The windbreak net is amazing, protecting us from the wind. Freestyle skier Winter Venecki also said: "In many competition venues, athletes have to fight against the wind, but here, the design of the windproof net ensures our safety and allows us to play more skillfully in the air." Team USA, the champion of the freestyle ski aerial skill mix, said, "It's perfect to have a windbreak on the sidelines, we really need it, and such a windbreaking net helps us to focus more on the game and also provide a higher level of competition, so we can perform so well and be successful in such a great arena."

At the National Bobsleigh Center in Yanqing, a "Terrain Climate Protection System" has also been installed, which can reduce the impact of solar radiation on the track and avoid direct sunlight affecting the quality of the ice surface.

During the design and construction process, the design team monitored the time and angle information of the solar incidence venue and track, and then accurately calculated the coverage area and angle of the awning through the protection analysis of the digital system. In this way, whether the sun rises in the morning or the sun sets at night, it can ensure that the track is not exposed to direct sunlight, ensuring that athletes' competition and training are not affected.

In addition, the sun blinds suspended on both sides of the track are an extended sun blind, which has a better sun protection effect. Secondly, its appearance is coated with a special reflective material, which can effectively reduce the impact of solar radiation, in addition, its surface has some tiny holes, which can improve its light transmittance and permeability, ensure that the sunlight will not be too strong, avoid interference with the race, and ensure the light of the track.

With these guarantees, whether it is the Yanqing Division or the Zhangjiakou Division, they can provide a suitable sports level for athletes in various sports of bobsleigh, sledding and skiing.
