Ice Cube a Water

The iconic building of the Beijing Olympic Games is the Water Cube Bird’s Nest, and the official name of the Water Cube is the National Aquatics Center. With the pace of the Beijing Winter Olympics, people are surprised to find that an “ice cube” has appeared. What is the relationship between this ice cube and the water cube?

The National Aquatics Center, also known as the “Water Cube”, is located in the Beijing Olympic Park. It is the main swimming pool built by Beijing for the 2008 Summer Olympics and one of the landmark buildings of the 2008 Beijing Olympics.

During the Beijing 2022 Winter Olympics, it will be converted into the “Ice Cube” as a competition venue for curling events, which can accommodate about 4,600 spectators. According to the renovation plan, the “Water Cube” will be the first venue in the world to set up a curling track on a swimming pool.

The National Aquatics Center is one of the main venues for the Beijing 2008 Olympic Games and one of the landmark buildings of the 2008 Beijing Olympic Games. With international level of facilities and reputation, there are more than 500,000 consumer residents in the surrounding area, convenient and fast traffic conditions on the subway Olympic branch line, professional companies with rich experience in stadium operation selected through international bidding, and outstanding management The project, and the adjacent large-scale related cultural and sports facilities, will have obvious competitive advantages in post-match operations. The Water Cube and the Bird’s Nest have become new landmarks in Beijing.

In August 2018, to undertake the ice project for the Beijing 2022 Winter Olympics, the remodeling of the venues has initially formed a remodeling plan. On December 26, 2018, the National Aquatics Center officially began to transform, starting a gorgeous turn to the “Ice Cube”. The transformed National Swimming Center will add a curling venue function in the competition hall to meet the needs of the Beijing 2022 Winter Olympics and Paralympics.

At the same time, an underground ice rink will be added to the South Square to serve the masses’ fitness on ice and popularize curling sports. The venue will complete the renovation of its permanent facilities in July 2020 to meet the needs of hosting the Winter Olympics test competition.

On December 8, 2019, the China Youth Curling Open successfully concluded at the “Ice Cube”. This is the first “ice-to-water conversion” carried out by the National Aquatics Center after a year of renovation of the Winter Olympics curling venue. It is also brand new. The debut “Ice Cube” ushered in the first curling event.

With this as a sign, in the ice event venues of the Beijing 2022 Winter Olympics and Paralympics, the National Swimming Center was the first to complete the ice-making work of the “Olympic Standard” ice surface, and the first to start high-level ice production. The official ice event, and the first to enter the actual operational test stage.

It is reported that it will take 3 weeks to complete this magical “water-to-ice conversion”. Of course, this process is not simply freezing the pool into ice, but involves the complex system engineering of the entire venue. The structure of the venue, humidity, temperature, lighting, etc. will be changed.

On December 21st last year, the National Aquatics Center “Water Cube” completed the second “water-ice conversion.” From swimming to curling, from Water Cube to Ice Cube, the National Aquatics Center has perfectly transformed itself. Compared with the first conversion, the second “water-to-ice conversion” effectively shortened the conversion period compared with the first. The first time the convertible structure of the ice rink was installed took 45 days, but this time it only took 20 days. Behind the greatly accelerated “water to ice” is the blessing of intelligent transformation.

It is understood that the second conversion built a conversion structure consisting of 2,600 thin-walled H-shaped steels and 1,570 lightweight concrete precast slabs. Each steel beam and concrete precast slab has its own “digital identity”. In this way, each component can be reset accurately and efficiently. During the construction process, through the combination of motion capture technology and construction measurement technology, the installation accuracy is greatly improved.

The changes brought about by technological progress not only allow the Water Cube to be converted into an Ice Cube faster and more conveniently, but also mean that the traditional stadiums will also be transformed into a truly intelligent stadium.
