The Hangzhou Asian Games will be held from September 10 to 25 this year. Yesterday (March 31), Shaoxing Baseball (Softball) Sports Cultural Center and Shaoxing Keqiao Yangshan Rock Climbing Base passed the functional acceptance of the event. So far, after nearly 5 years of construction, 56 competition venues for the 2022 Asian Games and Asian Paralympic Games in Hangzhou have been fully completed and have passed the comprehensive acceptance of the event functions. Among the 56 completed and accepted venues, the Hangzhou Olympic Sports Center Stadium, which hosts the opening and closing ceremonies and track and field events, has attracted much attention from the outside world. What is the current situation at this venue?
The “Big Lotus” by the Qiantang River, the first prize of the National Science and Technology Progress Award
28,000 tons of steel is used less than a stadium of the same size
Headquarter reporter Gao Wei: Hangzhou Olympic Sports Center Stadium looks like a “big lotus” from a distance. It consists of 28 large lotus petals and 27 small lotus petals. To underpin such a design, the architects carried out multiple rounds of optimization. After improvement, the steel consumption of Hangzhou Olympic Sports Center Stadium is only 28,000 tons, which is one-third less than that of a stadium of the same size. Thanks to this design, Hangzhou Olympic Sports Center Stadium won the Luban Award, the highest award in the field of architectural design in my country, and the first prize of the National Science and Technology Progress Award.
It can accommodate more than 80,000 people and will generate 48 gold medals here
The Hangzhou Olympic Sports Center Stadium can accommodate more than 80,000 people. Opening and closing ceremonies and track and field competitions will be held here. It is expected that more than 700 athletes from 45 countries will participate here, and a total of 48 gold medals will be produced.
The first batch of volunteers entered the venue for training
Today (April 1), the “Big Lotus”, which has passed the functional acceptance of the event, ushered in the first batch of volunteers to step in and train. On the playground, volunteers are placing track signs and running aids for the track and field. In the auditorium, volunteers were practicing how to guide the audience to their seats. Volunteers navigated through the smart applet to help the audience find the seat accurately.
Hangzhou Olympic Sports Center Gymnasium: Feel the Wonder of “Ice Basket Conversion”
Green, intelligent, frugal and civilized, it can be said that it runs through all aspects of the construction of the 56 competition venues of the Hangzhou Asian Games. Hangzhou Olympic Sports Center Gymnasium is the venue for the basketball finals of the Asian Games. Let’s find the “smart highlights” together↓
An ice hockey game was held on this concrete ground not long ago, and through one-click “ice basket switching”, the ice sports and basketball games can be seamlessly switched.
From the concrete floor to the ice surface to the basketball court, the secret to realizing the “ice basket conversion” lies in the ice-making pipes pre-buried in the ground of the stadium. When ice-making is required, the staff will install a circle of boundary walls on the site, and continuously cool the ground inside the boundary walls through ice-making pipes.
Liu Yang, a staff member of the event department of the Hangzhou “Asian Games Hall Three” operating company: (after cooling down) the temperature of the concrete floor has dropped to minus 10 degrees Celsius or minus 8 degrees Celsius. As soon as water is sprinkled on it, it will freeze. The staff kept sprinkling water on it and then making ice. When the ice surface reaches the thickness required for the competition, the ice making process is complete.
When the ice competition is completed, the scene can quickly realize the “ice basket conversion” without melting the ice surface.
Liu Yang, a staff member of the event activity department of the operating company of Hangzhou “Asian Games Hall 3”: Just remove the boundary wall, then lay a thermal insulation carpet on top of the ice surface that has already been made, and then splicing basketball wooden floors on top of the thermal insulation carpet. The ice hockey field can be converted into a basketball arena, and the conversion can be completed in 6 to 8 hours.
In addition to the efficient “ice basket conversion”, the staff can also view the situation in all corners of the venue in real time through the visual operation and maintenance management platform system, understand the operation status, and make adjustments at any time.
