"Record-breaking" is definitely the key word in the speed skating event of the Beijing Winter Olympics. As of February 9, the beijing Winter Olympics speed skating event has been competed for in four small events, and the championship results have all set olympic records (two of which have been refreshed twice). On the one hand, it reflects the athletes' efforts to continuously exceed the limit and pursue excellence, on the other hand, it also shows that the ice surface of the national speed skating "ice ribbon" in the competition venue is worthy of the "fastest ice".
Under the protection of "black technology" such as carbon dioxide transcritical direct cooling technology, the maximum temperature difference of the ice surface of the "ice ribbon" is within 0.5 degrees Celsius, laying the hardware foundation for the high-quality ice surface of the "ice ribbon". But if you want to have the "fastest ice", it is inseparable from the efforts of the ice-making team of the venue. On February 9, the speed skating competition was suspended for one day, but the Beijing Daily client reporter saw in the venue that the ice-making team was still busy, "We came to the venue at 7:30 in the morning to monitor the ice situation, on the one hand, because there will still be athletes to train today, on the other hand, because the ice surface must be carefully maintained." Shao Yi, head of the ice making team of "Ice Ribbon", explained.
For the ice team, ice monitoring is definitely an important task, because as the temperature, humidity and even the number of people and landscape arrangements inside the venue change, the ice surface state will fluctuate. An important task of monitoring is to measure the thickness of the ice surface, Shao Yi introduced: "Regardless of the straight curve, the thickness of the ice surface must be between 2.5 cm and 3 cm, so as to ensure flatness." Where the ice surface is thinner, the ice truck will sprinkle more water, and vice versa, sprinkle less water, and the ice knife on the car will shovel the ice deeper. He told reporters that in order to ensure the quality of the ice surface at all times, the "ice ribbon" race has been poured ice up to 8 times a day.
Such meticulous maintenance and adjustment have continuously improved the ice quality of the "Ice Ribbon". The Dutch star Krul, who won the silver medal in the men's 1500 meters on February 8, told reporters after the game that he felt that the ice surface was a little soft on the first day of training, but then it felt better and better, "The ice surface was adjusted very well, and when I played today, [the ice surface felt] like the ice rink in my hometown." ”
In the ice-making team of 18 people in the "Ice Ribbon", Mark Maiser, a Canadian expert who participated in the ice-making work of the Winter Olympics for the sixth time, is definitely a central figure. Shao Yi told reporters that Maiser is not only highly skilled, but also let him and the Chinese team members feel and learn the real "craftsman spirit", "he is like his own child, especially loving, never allow an unrelated person to go to the ice (will leave dirty things and traces), see a small black spot on the ice, will immediately stop to deal with." Shao Yi revealed that Maiser has no reservations in his work and has passed on his skills to the Chinese side, "After the Winter Olympics, we must strive to make the 'ice ribbon' continue to become the 'fastest ice', and we also hope that there will be more high-quality ice rinks in China." ”
Next, the "ice ribbon" will also compete for 10 speed skating events, the first 4 field record-breaking results, so that Shao Yi and his team are very popular, "Now everyone is full of energy, we will definitely be more meticulous, let the ice state get better and better, look forward to more athletes, especially Chinese athletes to break records here!" ”
