Xinhua News Agency, Beijing, March 10 (Reporter Zhang Wei) the reporter learned from the Office of Beijing major project construction headquarters that the first snowmobile sled track in China-the national snowmobile sled center track took 10 days to complete ice making on the 10th.
The national snowmobile sled center will undertake all competitions of snowmobile, steel frame snowmobile and sled during the Beijing Winter Olympics. The relevant person in charge of the Beijing Major Project Office introduced that in order to complete the ice-making task of the track, the construction unit Beijing control Beijing Olympic company co-ordinated the construction unit Shanghai Baoye company, in the U-shaped track of the national snowmobile sled Center, a refrigeration evaporation pipeline of about 120000 meters long is embedded, and the first snowmobile sled track ice-making and ice-repairing team in China is cultivated in advance.
The ice making work on the track includes five links: ice making, ice repairing, ice filling, cleaning and watering maintenance. Due to the different competition items and regions, the thickness of ice making and the ice making techniques of different wall sections are different, which puts forward high requirements on the skill techniques and physical quality of ice makers. In October, 2019, after the project set up the track ice making and repairing team, 10 people were quickly selected from 200 people and sent to Pyeongchang, South Korea for training and learning. During the training, China’s ice maker was highly recognized by the international ice maker and passed all the examinations at one time. At present, the team has mastered ice-making techniques such as judging ice-making conditions from frost formation and realizing “micro-finishing” of ice surface by controlling temperature, and the ice-making technology is becoming more and more skilled.
The relevant person in charge of Beijing Olympic control company introduced that the national snowmobile sled center is the first snowmobile sled project track in China, and the construction process fills many domestic technical gaps. In the past 4 months, the construction personnel participated in the construction without interruption, successfully completed the rapid installation of about 120000 meters of refrigeration evaporation pipeline, concrete injection of the main body of the track, hoisting of ammonia tank, debugging of refrigeration system, A series of important construction procedures such as the track ice making work have laid a solid foundation for the completion of the project by the end of this year.
