At the beginning of November 2021, the reporter first met Wei Qinghua, who was experimenting with snow machines, and his team was responsible for all the snowmaking tasks of the three competition venues of the ancient poplar stadium group in the entire Zhangjiakou Competition Area.
Wei Qinghua, manager of the mountain operation site of the ancient poplar tree venue group of the Beijing Winter Olympic Games: The area of snow making in the three arenas is nearly 300,000 square meters. This machine can produce 9 types of snow with different water content. In general, we use No. 5 snow, like this off-road venue we consider to do a little, use No. 3 snow, like in the early stage of this platform landing slope snow, you have to use No. 6, No. 7 snow, this choice of different models, to ensure that the venue of the event with snow.
On November 7, 2021, Chongli ushered in the first blizzard since the beginning of winter, the snow in the stadium was 20 centimeters deep, we thought this saved a lot of work for the snowmaking team, who knew that Wei Qinghua actually sent someone to clear all the snow off the track of the ski jump center. It turns out that these natural snowfall is easy to fall off on the slope, staying on it will cause safety hazards to athletes, only after hanging the snow net, and then re-artificial snow, and this is only the most basic standard for snow in the Winter Olympic Games.
Beijing Winter Olympics ancient poplar tree venue group mountain operation site manager Wei Qinghua: Jumping platform site, especially the landing slope, snow control on the landing slope is very fine, for example, it has a grass-roots, middle layer and surface layer, the density of each level is different, there are four or five thousand square meters of snow thickness is uniform, strict control, so this is more fine.
After the snowmaking began, the snow machine needed to work for 24 hours, and the workers on the site were working in three shifts.
Beijing Winter Olympics ancient poplar tree venue group mountain operation site manager Wei Qinghua: snowmaking is a very hard work, outdoor operations, especially at night operations, after a night down, the body is full of this snow frost, the body is also stiff at low temperatures, people are also very tired, but this job due to the limitations on the site, you have to have people in front of the snow machine to keep an eye on, can only overcome this difficult conditions, the job to do a good job.
January 20. After a month and a half of snowmaking and snow rolling, the three competition venues of the Zhangjiakou Ancient Poplar Stadium Group finally completed the construction of the track, but Wei Qinghua did not have the slightest joy of completion.
It turned out that part of the rolled snow surface had been destroyed. Wei Qinghua introduced that each venue of the Winter Olympics has more than 30 business areas, and the cross-operation of various fields will inevitably produce some conflicts. In Wei Qinghua's office, there was a large notebook made of kraft paper, and every day he wrote down the problems that needed to be solved that day.
On January 28, the off-road track of the Ancient Poplar Stadium Group was finally delivered as scheduled.
John, mountain operation manager of the ancient poplar tree venues at the Beijing Winter Olympics: (Snowmaking) This is very hard work, and it requires a lot of people to work day and night. The staff worked harder than anyone else I've worked with. Mr. Wei is excellent in terms of management and I am satisfied with the results of snow making and rolling.
Wei Qinghua, manager of the mountain operation site of the ancient poplar tree venue of the Beijing Winter Olympics: You want to say that this work is really hard, but there are several times in this life that people can take responsibility for the country. We can work at the forefront, and in the preparation of the venue, we are the leaders, worth it.
