The 2022 Beijing Winter Olympics will be held in Beijing, Yanqing and Zhangjiakou, with a total of 25 venues, including 12 competition venues and 13 non-competition venues.Beijing is the first city in the world to host both the Summer and Winter Olympics, so the Bird’s Nest will be the first Olympic stadium to host both.At the Winter Olympics, venues such as the Bird’s Nest, which combines intelligence and technology, are a highlight of the event.The venues in Beijing, Yanqing and Zhangjiakou have left a deep impression in terms of venue construction, infrastructure, smart services and green energy.Venue designers overcome the difficulties of construction and transformation, the depth of the Winter Olympics and technology integration, the Winter Olympics and nature close, the winter Olympics and history closely linked, will attract the attention of the world.Among the 12 venues, The Beijing venue includes the National Speed Skating Hall, the National Aquatics Center, the National Stadium, the Wukesong Arena, the Capital Stadium and the Shougang Ski Big Jump, which will host all ice events and snowboarding and freestyle skiing big jump events.Yanqing includes the National Alpine Ski Center and the National Bobsled Center.The Zhangjiakou competition area includes the biathlon Center, the National cross-country ski resort, the National ski jumping Resort and the Genting Ski Park.National Aquatics Center national Aquatics Center: The “Ice Cube” converts a swimming pool into a curling rink. The National Aquatics Center is the first sports arena in the world to achieve “water ice conversion”.As the only Olympic stadium in the world that can operate both water and ice events, and the first Olympic stadium in the world to set up a curling track on the swimming pool, the National Aquatics Center has added ice functions on the basis of maintaining the water cube.Therefore, the National Aquatics Center is affectionately known as the “Ice Cube”.Here, many new achievements in the field of science and technology, such as architecture, structure, ice making, dehumidification, lighting and sound field, are applied.Curling requires a very high level of ice surface. Under the weight of 150 kg per square meter, the ice deformation should not exceed 1 mm. The surface of the track will be subtly changed by the continuous sliding of the curling stone, repeated ice repair by the ice maker, and even slight changes in the indoor environment.At the same time, curling requires the humidity of the venue to be below 30%, the temperature of the ice surface to be about minus 8 degrees Celsius, the air temperature of 1 meter above the ice surface to be 10 degrees Celsius, and the indoor temperature to be less than 16 degrees Celsius. These factors will directly affect the friction coefficient of curling and ice and determine the track quality.In the process of transforming the National Aquatics Center from a high temperature and high humidity swimming pool environment to a low temperature and dry ice rink environment, researchers presented a detailed technical transformation plan of “water ice transformation”, involving construction, structure, waterproof, membrane maintenance and other engineering fields, about 70 independent construction areas, 50,000 square meters of transformation area.Taking the transformation of the curling track as an example, the National Aquatics Center built a convertible structure in the middle of the competition hall and installed a detachable ice making system.After emptying and draining the pool, the steel supporting system and concrete panels were installed, and ice pipes were laid to form a curling arena with four standard tracks.This conversion mode not only realizes the exchange of “Water Cube” and “Ice Cube”, but also realizes the reuse of converted materials, greatly reducing the cost of demolition and reconstruction in the later period.The “water ice conversion” technology allows the National Aquatics Center to switch between “water” and “ice” functions, allowing it to carry out water sports, ice sports and various large-scale activities at the same time.There will be three gold MEDALS in the men’s, women’s and mixed doubles.It is worth mentioning that during the competition, the “Ice Cube” built a new “giant screen” of 170 square meters. The “curling operation capture technology” introduced by the scientific research team can capture the real-time picture of the competition, clearly display the running track of curling, and increase the fun of the audience.The Capital Stadium is an Olympic stadium with a long history. It was built in 1968.During the Games, it will host events in figure skating, short track speed skating and ice hockey, and may be the site of China’s first gold medal.This time, the Capital Stadium borrowed from the Beijing Winter Olympics, ushered in a gorgeous “change of outfit”.Inside the venue, the main competition area is made up of 21 quality flexible floors 30 meters in length and 3.5 meters in width, with an ice rink underneath.According to the introduction, the reason for this layout, is to enable the venue to achieve rapid and efficient conversion.Terrazzo floors already existed under the floor during the 2008 Beijing Olympics, a huge breakthrough in Olympic stadium technology.When water is poured on the terrazzo floor, the low temperature ammonia drain inside the terrazzo cools and turns the water into ice all year round for ice hockey, figure skating and short track speed skating competitions.Unlike other expansions to increase seating capacity, the Capital Stadium has reduced seating capacity, both to increase the distance between the seats and to help the audience enjoy the best view of the high-level competition.At the same time, in figure skating and short track speed skating, the venue will attract the audience with immersive competition areas, adding sky projection and ring screen, three-dimensional effect is more obvious, with the venue’s sound and optical technology, the audience can feel the speed and passion of ice competition.The short-track speed skating and figure skating events will all take place there from February 4 to 19, with 14 gold MEDALS to be awarded.National Alpine Skiing CenterWinding down “white waterfall” alpine skiing, known as “pearl on the crown of the winter Olympics”, and as for the competition of the national center for alpine skiing, built around the mountain, down from an altitude of 2198 meters peak overlooking, seven runs like a white waterfall, from the top of the mountain to the valley winding “flowing”, like a bright pearl, set foot on the Great Wall.National alpine skiing center located at Beijing yanqing northwest area, based on the small tuo mountain natural yamagata, here are 7 trail, a total construction including 3 game trails, four training runs, about 3 km, the longest track racing circuit drops 900 meters, maximum gradient is close to 70%, the highest speed can reach 130 kilometers per hour.As the venue with the largest area, the highest altitude, the largest number of foreign staff and the largest number of participating countries, the National Alpine Skiing Center has steep mountains and complex site conditions.Currently, each stage of the course has its own name, such as white face, Roller Coaster, Panda Jump, Silk Road and Haituo Bowl, which are all named by the International Ski Federation and released to competitors.In addition, the national Alpine Ski Center ropeway system consists of 9 aerial ropeways and 2 tow ropeways, with a total length of 10.3 kilometers.During the Winter Olympics, all alpine skiing events will be held here, divided into speed series and technical series, a total of 11 events, 11 gold MEDALS, including the speed series is divided into downhill and super G, technical series is divided into giant slalom and slalom events and team events.In addition, there is the downhill and slalom combined alpine skiing all-around competition.National Bobsled Center National Bobsled Center:Article 16 bending of snow flying as China’s first, and only a winter Olympics standard snowmobiles sled track, total length of 1975 meters, the main national center for snowmobiles sled track circuit space for long linear hyperbolic panel shell structure, relying on the altitude of 2198 meters of the small tuo mountain natural yamagata construction, like a dragon flying drooling over the mountain ridges.The terrain of the National Snowmobile Center is complex, with a height difference of about 150 meters from the high point in the north to the low point in the south, and an average natural slope of more than 16%.The circuit is divided into 54 cooling units and consists of 16 turns with different angles and gradients. The 11th turn is the unique 360 degree turn in the world, which is also the first in the world.The track has an altitude of 1017m at its highest point, starting zone 1, and 896m at the bottom of turn C16, with a maximum drop of 121m and a top speed of 134.4km/h.As one of the new venues of the Winter Olympics with the highest design difficulty, the most difficult construction and the most complex construction technology, the National Bobsled Center has created the miracle of the Winter Olympics from scratch.At present, the National Bobsled Center and the National Alpine Ski Center are regarded as the miracle projects in the history of Chinese architecture.During the Winter Olympics, there will be three events in bobsled, bobsled and skeleton bobsled, which will produce 10 gold MEDALS.Source: Thoughtful Shanghai
