It is reported that the starting area, slide area, grandstand area and ending area of the national ski jump center have been completed in September. This means that the four competition venues located in Zhangjiakou competition area - Yunding Ski Park, national ski jumping center, national cross-country skiing center and national winter biathlon center are all qualified for competition.
In particular, the national ski jumping center, which recently opened its mysterious veil, is known as snow Ruyi because it is similar to the traditional Chinese auspicious ornament Ruyi. As the competition venue with the largest engineering quantity and the highest technical difficulty in Zhangjiakou competition area of the 2022 Beijing Winter Olympic Games, the project is the first ski jumping ground in China and the first ski resort in the world to adopt full reinforced concrete frame structure and set up large buildings in the top departure area.
On the second floor open platform of the national cross country skiing center technical building, there are only a few supports on both sides of the bottom of the three or four story building, which looks like hanging in the air from a distance. It is said that this structure can not only increase the use area, but also has good seismic resistance. Compared with reinforced concrete structure, it has more advantages in construction period, engineering cost and environmental protection.
With the continuous promotion of the preparations for the Winter Olympics, Zhangjiakous supporting industries for the Winter Olympics have been constantly improved. By the end of July this year, the construction of two ice and snow industrial parks in Zhangjiakou high tech Zone and Xuanhua district has been steadily promoted. This year, 68 ice and snow industry projects have been signed and 57 projects have been implemented, with a total investment of 33.173 billion yuan. (end) today, there are many tower cranes in Chongli District of Zhangjiakou, and the construction of Winter Olympic projects goes hand in hand. According to Wei Jingqi, novel coronavirus pneumonia, the head of the national cross-country skiing center project of the Beijing Zhangjiakou Winter Olympic Games project group, the Chinese Railway Construction Industry Group Co., Ltd., who has resumed work to the completion of the project, has been working three shifts in order to seize the time limit for the delay of the new crown pneumonia outbreak.
