On November 27, the renovation project of the "Water Cube" of the National Swimming Center was completed, making it the first venue to be completed for the 2022 Winter Olympic Games in Beijing.
As a double Olympic Stadium owned by Beijing state owned assets company, the water cube of National Swimming Center is the landmark venue of the 2008 Beijing Olympic Games. It undertakes swimming, diving, synchronized swimming and other water sports. During the 2022 Winter Olympic Games and the winter Paralympic Games, the National Swimming Center "Water Cube" will undertake curling and wheelchair curling competitions.
In 2019, "Water Cube" of National Swimming Center completed the conversion of swimming pool and ice rink for the first time through the creative "water ice conversion" scheme, becoming the world's first venue to complete "water ice conversion", realizing the gorgeous turn of "Water Cube" into "ice cube". In December 2019, China Youth curling open was successfully held, becoming the first Winter Olympic stadium to open high-level Ice Games and enter the actual combat test stage.
According to the reconstruction plan, the renovation of "Water Cube" involves construction, structure, waterproof, membrane maintenance and other engineering fields, with about 70 independent construction areas and 50000 square meters of reconstruction area. The most difficult point in the reconstruction is to add "water ice conversion" on the basis of water cube's water function. In the middle of the competition hall, a curling field with four standard tracks is formed by building a convertible structure and installing a detachable ice making system. This conversion mode not only realizes the exchange of "Water Cube" and "ice cube", but also realizes the reuse of conversion materials, which greatly reduces the cost of demolition and reconstruction in the later stage.
At present, with the advent of winter, "Water Cube" has started the second "water ice conversion" work, and a new round of venue conversion structure construction has been started in the competition hall. A new ice surface is about to appear, which will also provide a new round of ice experience venues for the public.
The "water ice conversion" scheme of "Water Cube" is a vivid practice of "repeated utilization, comprehensive utilization and sustainable utilization" of Olympic venues under the leadership of Beijing state owned assets Corporation. After the "Water Cube" is transformed into "ice cube", the competition hall will be equipped with the conditions for hosting Ice Games, water sports events and large-scale commercial activities.
After the competition, the competition hall of National Swimming Center will realize the free switching between "water function" and "ice function", which not only retains the original color of "Water Cube" to undertake water sports events, but also adds the charm of "ice cube", so as to carry out and popularize ice sports and become a model of sustainable utilization of Olympic venues.
At the same time, in order to do a good job in the later operation of the stadium, the National Swimming Center has also built two ice surfaces using the underground space of the South Square, one for the standard ice rink and the other for the curling field. At that time, it will serve as an experience base for curling projects in the Olympic central area, providing an open platform for the public and helping 300 million people participate in ice and snow sports.
