"Ground Commentary" Sunbird Times: Read the craftsman spirit in "Ice miracle"

The 2022 Beijing Winter Olympics are being held. There are 12 competition venues in 3 competition areas of Beijing, Yanqing and Zhangjiakou, 3 non-competition venues such as Winter Olympic Villages and Main Media Center, which have attracted much attention. Whether it is the "Ice Ribbon" of the National Speed Skating Hall or the "Crystal Shoes" of the Shougang Ski Jump, or the "Snow Ruyi" of the National Ski Jumping Center, a series of amazing "Winter Olympic Projects", the "Chinese Speed" and high-quality achievements that amaze the world, embodying the craftsman spirit of the builders to overcome difficulties and strive for excellence.

Visit experts before the design of the Winter Olympic venues and learn from various places. The design of the Venues for the Winter Olympics is a "theoretically feasible, but unprecedented in reality" approach. In order to create the "fastest ice" that will help athletes skate their best, the builders of the "ice ribbon" visit experts and travel from place to place. By closely focusing on the "fastest ice" and green and low-carbon goals, with the support of key research and development plans, the "ice ribbon" has innovated the carbon dioxide transcritical direct cooling ice system, making the "ice ribbon" the world's first Winter Olympic speed skating venue that uses this technology to cool; through the development and application of intelligent technology, it has innovated the intelligent integration and digital twin platform, and built the "ice ribbon" into a smart stadium with feeling, breathing, memory, thinking and self-regulation. Adhering to the design concept of excellence, the builders of the "Ice Ribbon" smart venue finally formed a "Chinese plan" with many scientific and technological highlights and can withstand the test of history, providing important support for the complete success of the Winter Olympics.

When building the venues of the Winter Olympic Games, we worked hard and overcame difficulties. The construction of Winter Olympic venues focuses on the goals of "building well" and "using well", and "not stopping for a moment" to grasp the progress of the construction period. In order to provide a good venue guarantee for the Winter Olympics, the builders of the Winter Olympic venues were on duty in the cold wind of Xiaohaituo Mountain, working in the cold winter night, and at most 6 times a day to repair the ice surface; in order to provide athletes with a better natural wind barrier, "Snow Ruyi" was erected between the valleys, and for each pillar supporting the snow path, a separate template and frame were formulated, the longest pile hit 23 meters underground, it was the Winter Olympic venue builders who were draped in starlight, bathed in morning dew, struggling to overcome difficulties, in order to " One step can not be wrong" attitude to seek construction precision, the courage to break through the technology, ability, pattern, so that the "Chinese plan" composed of Chinese design, Chinese technology, Chinese materials, Chinese manufacturing, the construction of Winter Olympic venues, in terms of green, environmental protection, sustainable for the Olympic Games set a new benchmark.

Precise inspection and fine regulation during the operation of the Winter Olympic venues. The operation of the Winter Olympic venues is to achieve "ice conversion" in two hours to help athletes achieve good results. To this end, after the Winter Olympic venue builders repeatedly delve into the research, during the race, the temperature difference of the ice surface track will be accurately controlled at 0.5 degrees Celsius with carbon dioxide transcritical direct cold ice technology to ensure that the ice surface hardness is consistent, reduce the influence of external factors on the athletes' gliding level, and at the same time use the "strongest brain" to collect and calculate the venue humidity, temperature, wind speed, number of spectators, etc. detected by intelligent sensors in real time, regulate the seat air supply system and dehumidification system, so that the ice surface always maintains the best state, in addition, It is also compared with the BIM model through laser scanning to test and ensure that the 120,000-meter stainless steel ice pipe under the ice rink is in a precise position to ensure that the ice temperature is uniform. It was the precise adjustment and fine regulation of the builders of the Winter Olympic venues that finally made the two venues, different ice surfaces, lay a solid foundation for the Olympic athletes to achieve good results, and spawned more good results and new records.

The Winter Olympics are in full swing, when we lament the black technology of the "ice ribbon" and the good results of athletes, we should also pay attention to the excellence of the builders of the Winter Olympic venues from design to regulation, and it is precisely because they have accurately grasped every detail that they have presented this wonderful, extraordinary and outstanding ice and snow event, which is the display of the craftsman spirit and the manifestation of the Chinese spirit.
