On February 11, the men's steel frame snowmobile competition of the Beijing Winter Olympics began to compete in the "Snow Dragon". China's Yan Wengang won the third place with a total time of 4:01.77 in four rounds, achieving a breakthrough of "zero" medal in China's steel frame snowmobile project, refreshing the best time for the Chinese Olympic Games, and another Chinese athlete, Yin Zheng, won the fifth place in 4 minutes 02.13 seconds.
In addition, on the morning of February 11, Zhao Dan, a "post-00" youngster who served as the female flag bearer of the Chinese delegation at the opening ceremony of the Beijing Winter Olympics, and teammate Li Yuxi also represented the Chinese team. It is reported that this is the first time that Chinese women's steel frame snowmobile athletes have participated in the Winter Olympics, and the performance of the two female athletes is currently very outstanding, and Zhao Dan has set a new record for the women's steel frame snowmobile track with a time of 1 minute 02.26 seconds, temporarily ranking third.

It is understood that the steel frame snowmobile known as the "ice dive machine" is extremely fast, because there is no steering and braking device, athletes need to lie forward on the sleigh, relying on the slight shaking of the head and body to control the direction, and slide down the ice track at high speed. The good results of athletes are inseparable from the high-quality construction of venues.

The National Bobsleigh Center venue is one of the new competition venues with the most difficult design, the greatest construction difficulty and the most complex construction process in the Beijing Winter Olympic Games. With a total length of 1975 meters, a total of 16 curves with different angles and slopes, a maximum design speed of 134.4 kilometers per hour, and a vertical drop of more than 120 meters, it is the first bobsleigh track in China, the third in Asia and the 17th in the world to meet the olympic standards. Because from the air, the track winds down like a dragon coiled between the mountains, so it is also known as the "Snow Dragon". Among them, the 11th bend is currently the only 360-degree slalom in the world.
Li Xinggang, chief architect of China Architectural Design and Research Institute, introduced that the construction of "Snow Tour Dragon" transforms the traditional "dry-type" residential structure in the southwest mountains of the mainland into modern construction technology, develops a high mountain overhead platform system, and builds a steel structure support along the mountain trend to "support" the basic platform, which not only does not destroy the mountain environment, but also improves the construction efficiency and quality, and can quickly restore the original appearance of the terrain according to demand after the game.
In order to avoid the ice surface of the track from softening due to direct sunlight during the day, the bobsleigh course is usually built on the northern slope of the mountain, but there is only one area on the southern slope of Haituo Mountain with a suitable construction slope. Therefore, Li Xinggang's design team used the natural shading of natural terrain, combined with the design of artificial terrain, awning, windshield and so on, to achieve the research and development and construction of the "Snow Dragon" terrain climate protection system, and the energy-saving indicators of the track were even better than those of the north slope.

In addition, the design team also installed a pedestrian walkway on the awning as a counterweight of the shed structure, which is convenient for maintenance personnel and can be used by spectators and tourists. Hidden under the shingle roof of the awning, the "Snow Dragon" adds to the Chinese charm of the mountain forest veranda.
"Passing on the cultural concept and ecological values of Chinese to the world is the core idea of Yanqing Division's design." Li Xinggang said that the construction of Olympic venues must not only technically meet international requirements, but also be a super project built under the eyes of the world, from the grandeur of 2008 to the ecological integration in 2022, "Every Olympic project is creating history."
