What is the internal structure of ice cubes?

The exterior wall of ice cube Exhibition Hall is very distinctive. Decorated with ice patterns, it looks like an "ice cube" when lit at night. "ice cube" also built two ice surfaces (one is a standard ice rink and the other is a curling venue) by using the underground space of the South Square as the experience base for curling events in the Olympic Center, providing an open platform for the citizens.

20 19, "water cube" introduced "water-ice conversion" for the first time. The efficiency of the second "ice-water conversion" is four times that of the first one. It took 45 days to install the convertible structure of the skating rink last year, and this time it only took 10 days.

Yang Qiyong, general manager of the National Swimming Center, revealed that due to the high-tech blessing, the assembled quick disassembly technology and leveling dynamic monitoring technology were applied. The former optimizes the sequence of material entry and construction organization, and ensures that the components are installed in the original position during reconstruction. The latter solves the "pain point" of low leveling efficiency of laying 1500 precast concrete slab on the transfer structure.

"Water-ice conversion" is a "Chinese scheme" for the innovative utilization of stadiums. It refers to the construction of an ice rink convertible structure in the swimming pool and the installation of a detachable ice-making system to form a standard curling venue. The scheme supports the transformation of "Water Cube" into curling venues and wheelchair curling venues for the Beijing Winter Olympics on the basis of retaining its water function.

Yang Qiyong introduced that the "water-ice conversion" is actually very complicated, and the change is not only in the swimming pool, but also requires the machinery, equipment and control system in the backstage of the venue to have the ability to convert with the functional requirements of the venue, and also undertake commercial activities here. This rapid switching of multiple scenes poses a great challenge to the intelligent level of venue equipment and even the level of property management.

Extended data

Winter Olympic projects such as "Ice Belt", "ice cube" and National Gymnasium have been completed one after another;

It is reported that the Winter Olympics projects such as "Ice Ribbon", "ice cube" and National Gymnasium have been completed one after another, and Beijing Winter Olympics Village is expected to be completed in June 20021year. The reconstruction and construction of the Winter Olympics venues such as "Bird's Nest", Beijing Awards Plaza and Beijing Winter Olympics Doping Testing Center are under way.

The National Speed Skating Hall, known as the "Ice Belt", was officially completed. The main stadium has a building area of about 80,000 square meters and a height of 33 meters, and can accommodate about 65,438+2,000 spectators. The National Speed Skating Hall is designed with full ice, which is the largest ice surface in Asia and the largest transcritical direct cooling ice surface with carbon dioxide in the world.

At the same time, the National Speed Skating Hall is an out-and-out intelligent venue. Based on the construction of 5G network, the introduction of technologies such as "indoor and outdoor integrated positioning and navigation system" into the venue is like equipping the venue with a "brain", which can provide high-quality watching experience and complete service guarantee for spectators, event organizers and participants in the future.

The National Aquatics Center (referred to as "Water Cube") located in the southeast of the "Ice Belt" has recently completed the "water-ice conversion" and turned into an "ice cube". The National Gymnasium has also completed the renovation, adding ice-making function and dehumidification system, building a new ice hockey hall as a training hall on its north side, and adding facilities such as changing rooms. After the renovation, the total area of the venue is about 98,000 square meters, and it is equipped with two ice hockey ice surfaces that meet the Olympic standards. One ice hockey ice surface is used for official competition, and the other is used for pre-competition training and warm-up during the Beijing Winter Olympics.
