Since this is the first time that this event has come to the south of the Yangtze River, snow making methods, snow making equipment, and laying methods have changed to the previous mode, just to adapt to the “warm” weather in Hangzhou.
Xinhua News Agency, Hangzhou, December 18 (reporter Xia Liang) the 2019 International snow Federation cross-country skiing China tour Hangzhou station competition ended at Huanglong Sports Center in Zhejiang province on the 17th, this is also the first time that this world’s top city cross-country skiing event has crossed the Yangtze River.
Subject to natural conditions and other factors, ice and snow sports are known as “difficult to go out of the mountain customs” in our country. However, in recent years, with the rise of “skiing fever”, the “white economy” represented by skiing is boosting ice and snow sports to get out of Shanhaiguan and come to Jiangnan.
It is understood that since this event is the first time to come to the south of the Yangtze River, snow making methods, snow making equipment, and laying methods have all changed to the previous mode, just to adapt to the “warm” weather in Hangzhou.
Li Xiaobo, the head of the competition snow making department, said that since the ordinary snow making machine sprays water into the air and condenses into snowflakes in the air, it can only be snow making under the temperature of 0 ℃, hangzhou is far from reaching this temperature condition.
“For this competition, the organizing committee specially introduced two high temperature resistant snowing machine from Italy. The principle of this kind of machine is to connect the water source to the machine, directly cool down inside, condense into snowflakes and ice crystals, and spray them out from the machine.” Li Xiaobo said.
In order to reduce the risk of transportation in higher temperature, the organizing committee chose to snow making directly at the site. Li Xiaobo said that in order to ensure that the snow path is always kept in a low temperature state, the choice of the underlying snow quality also has a doorway. “Customized plastic film needs to be laid under the built snow pile to ensure heat insulation and ventilation at the same time, so that the melted snow water can be discharged in time, and the snow pile should be covered with the top film.”
Finally, the track, which covers an area of about two standard football fields and has a length of 1300 meters, was successfully completed. After the game, it was also praised by athletes from all over the world.
Sport Bureau of Zhejiang province the relevant person in charge said that he hoped to accelerate the strategy of “South exhibition, West expansion and East movement” of ice and snow sports through high-level competition guidance, so as to enable Hangzhou people to appreciate, participate, experience and interact, feel the charm of ice and snow sports at close range, release the passion in winter, and let more regions, more social forces, more ice and snow sports enthusiasts participate in the flood of popularity and development of ice and snow sports.
Insiders believe that the city cross-country skiing tour breaks the shackles of traditional cross-country skiing, enters the life circle of ordinary people, turns streets into snow lanes, and holds strong antagonism in the core area of the city, the highly ornamental racing project enables more skiers to watch high-level skiing events at close range, stimulating people’s enthusiasm and enthusiasm to participate in ice and snow sports, it is a useful attempt to promote “0.3 billion people participating in ice and snow sports.
