Xinhua News Agency, Beijing, November 15 (Reporter Zhang Jiye) on the 15th, the National Alpine Ski Center in the Yanqing District of the Beijing Winter Olympic Games began to make snow officially. Yellow and white snow machine ejected a beautiful water mist, and then quickly condensed into snow in the air, such as smoke like jade, falling from the sky. The reporter learned from the Beijing Organizing Committee for the Winter Olympic Games and the Municipal Office of Major projects that in about 50 days from the 15th to the end of December, the National Alpine Ski Center will complete all the snow-making work related to the test race. Prepare for the first test match of "meeting Beijing" for the Beijing Winter Olympic Games in February next year.

The Yanqing District of the Beijing 2022 Winter Olympic Games is mainly responsible for alpine skiing and sleigh racing. The National Alpine Ski Center, which is responsible for alpine skiing, will build seven snow tracks with a total length of about 10 kilometers and a maximum vertical drop of more than 900 meters. Beijing 2022 Winter Olympic Games alpine skiing will hold downhill, super big slewing, big slewing, slewing and other 11 events. In February 2020, the National Alpine Ski Center will usher in the first test match of the Beijing series of winter sports events and the International Snow Federation Alpine skiing Men's World Cup Yanqing Station.

According to the person in charge of the Municipal Major Project Office, in order to meet the needs of the first test race of "meeting Beijing" at the Beijing Winter Olympic Games in February next year, the speed track, training track, and related technical roads of the National Alpine Ski Center in Yanqing have all been completed. Snow will be finished by the end of this year. At present, the projects in the Yanqing race area are progressing smoothly, the relevant ropeway systems of the service test race have been operated and debugged, and the internal and external road systems, power and communication systems in the race area have been connected, providing a reliable guarantee for the first test race.

It is understood that the national alpine skiing center test race related to snow related to a total area of about 260000 square meters, snow volume of about 260000 cubic meters. According to the snow-making plan, the snow-making will be divided into three different types of snow tracks (racing track, training track, technical road) into 16 regions, a total of 117 snow machines and 19 snow pressure vehicles.

According to the person in charge of the North Control Beijing Olympic Construction Co., Ltd., the construction unit of the Yanqing competition area, in order to ensure that the athletes can reach the maximum speed of 130-140 km / h, the International Snow Federation has strict requirements on the hardness of the snow track. Therefore, snow making has become the most critical link. According to the requirements of the race, the surface of the snow track must remain crystalline, similar to the ice surface, this kind of snow is called ice snow. Ice snow can reduce the friction between the snowboard and the snow track, so that the snow track is not easy to be damaged. In the case of athletes turning at high speed, it can also ensure that the surface of the snow track is smooth and smooth, so that no matter how many players appear, the state of the snow track is the same relatively perfect, in order to ensure the fairness of the competition.

The production process of ice snow is relatively complex, first through artificial snow to complete the snow path modeling, and then open the snow path to turn out the underlying snow, and then evenly and continuously inject water into the snow surface to increase the water content of the snow. After water injection, the wet snow is stirred evenly and then flattened by repeatedly turning and pressing the snow truck, after consolidation and sinking, the surface snow weathered to form soft snow, and then cleared manually many times before a professional snow path can be formed.

It is also understood that the water used to make snow at the National Alpine Ski Center is sent through the 7.5km underground integrated pipe corridor to the pond dam of 1050 meters above sea level and the reservoir of 1290 meters above sea level for storage. Through the third-stage pumping station, the snow-making water will be injected into each snow-making system, and finally reach the starting platform near the highest point of 2198 meters in Xiaohaituo Mountain. At the same time, the National Alpine Ski Center has also built a perfect snowmelt water, Rain Water recycling system, recycled water resources will be reused.
