During the 2008 Olympic Games, the National Aquatics Center will undertake swimming, diving, synchronized swimming, water polo and other competitions, and can accommodate17,000 spectators, including 6,000 permanent spectators. During the Olympic Games,1/0,000 temporary seats will be added (to be removed after the games). After the Olympic Games, it will be built into an international advanced center integrating swimming, sports, fitness and leisure.
design
The design scheme of the National Swimming Center is the "Water Cube" ([H2O]3) scheme produced by the global design competition. The scheme was jointly designed by China State Construction Engineering Corporation, Australian PTW Architects and ARUP Australia Limited. The design embodies the design concept of [H2O] 3 ("Water Cube"), which integrates architectural design and structural design. The design is novel, unique in structure, coordinated with the national stadium, fully meets the requirements of the 2008 Olympic Games in function, and is easy to operate after the game.
Beijing State-owned Assets Management Company is responsible for the construction, management and operation of the National Swimming Center, which was started at the end of 2003, completed and put into trial operation before the end of 2007, and accepted the inspection and acceptance by the International Swimming Federation and the International Olympic Committee.
Green venues
As the three core concepts of Beijing Olympic Games, Green Olympics, Hi-tech Olympics and People's Olympics have programmatic guiding significance for all the work of Beijing Olympic Games. Of these three concepts, Green Olympics is the first. From the definition of green Olympics in Beijing Olympic Action Plan, it is not difficult to see that every link of realizing green Olympics needs people's high-standard ecological literacy to ensure that all work should be carried out according to standards.
The main advanced energy-saving technologies in the construction of the National Swimming Center include the selection of heat pump, the utilization of solar energy, the comprehensive utilization of water resources, advanced heating and air conditioning systems, control systems and other energy-saving and environmental protection technologies, such as the use of internal and external wall insulation to reduce energy loss; Adopt efficient and energy-saving light source and lighting control technology. The adoption of these new standards, new technologies and new materials has played a good demonstration role for China's future building energy-saving construction, and can further promote and promote the development of China's building energy-saving technology industrialization.
The ETFE membrane material used for the first time in the Water Cube can best represent the "Water Cube". The shape of "Water Cube" looks like a blue water box, while the wall looks like a group of irregular bubbles. The material used for this bubble is "ETFE", which is what we often call "polyvinyl fluoride". This material has good corrosion resistance, heat preservation and strong self-cleaning ability. Foreign anti-aging tests prove that 15 can be used for 20 years. Moreover, this material is also very strong, and it is said that people jumping on it will not be damaged. At the same time, because of its water repellency, it can be cleaned by natural rain, and it is a new type of environmental protection material. An ETFE film such as "Water Bubble" has good compression resistance, and its thickness is only as thick as an air pillow made of paper ETFE film, and it can even bear the weight of a car. According to the position of the air pillow, there are uneven plating spots on the outer film, which will effectively block the direct sunlight in the museum and play a role in shading and cooling.
Water cube water saving scheme
Automatic control of changing water in swimming pool
In order to ensure that the water quality of "Water Cube" meets FINA's latest hygiene standards, the water in the swimming pool will be purified by sand filtration-ozone-activated carbon, all of which will be disinfected by ozone. According to reports, ozone disinfection can not only effectively remove the odor of pool water, but also eliminate the stimulation of pool water to human body.
In addition, automatic control technology will be adopted in the whole process of changing water in the swimming pool to improve the operation efficiency of the water purification system, reduce the consumption of water purification agent and electricity, and save more than 50% of the water supply of the swimming pool. In addition, the swimming pool and water recreation pool will use impervious concrete to prevent leakage.
Bath water is used for flushing toilets and irrigation.
Besides swimming pool water, other water used by the water cube is also very economical. After biological contact oxidation, filtration, activated carbon adsorption and disinfection, bath wastewater is used for toilet flushing in venues, garage floor flushing and outdoor greening irrigation. This alone can save 44530 tons of water every year. In addition, in order to reduce water evaporation, the outdoor green space of "Water Cube" will be irrigated at night, using Israeli micro-irrigation nozzles, which can save water by 5% after completion.
Sanitary ware is equipped with a water meter to measure water.
In order to reduce people's waste of water as much as possible, "Water Cube" uses inductive flushing valves for toilets, bath faucets, basins and other equipment to reasonably control the water output of sanitary ware, and sets water meters at various centralized water consumption points to measure water consumption. It is estimated that through these measures, water can be saved by about 10%.
In addition to bath water, the Water Cube will also set up a drinking place in the competition hall to provide drinking water for athletes and spectators. In order to avoid secondary pollution and waste of drinking water, the drinking water of "Water Cube" will be treated by terminal direct drinking water treatment equipment.
Construction technology of water cube
Membrane structure architecture is the most representative brand-new architectural form in 2 1 century, and has become one of the main forms of long-span space architecture so far. It combines architecture, structural mechanics, fine chemical industry, material science and computer technology, and constructs a symbolic spatial structure. It not only embodies the beauty of the structure, but also fully shows the architect's vision and enjoys the romantic space of nature. In the architectural design of the 2008 Olympic Games, the application of membrane structure has been perfectly reflected.
"Water Cube" is the largest membrane structure project in the world, and the most advanced environmental protection and energy-saving ETFE (tetrafluoroethylene) membrane material is used outside the building. Tan, general manager of the National Gymnasium Project, revealed that the life of this material is more than 20 years, but it will actually be longer than this, and people can walk on it, which feels particularly good. At present, only three companies in the world can complete this membrane structure.
The whole building of "Water Cube" consists of more than 3,000 air pillows of different sizes and shapes, covering an area of 654.38+10,000 square meters, ranking first in the world. In addition to the ground, the exterior adopts membrane structure. The successfully installed air cushion will be inflated into "bubbles" through the inflation pipe installed on the steel frame in advance, and the whole inflation process will be intelligently monitored by the computer, and the "bubbles" will be kept in the best state according to the air pressure, lighting and other conditions at that time.
This kind of film material similar to "bubble bag" has self-cleaning function, which makes the film surface basically dust-free. Even if there is dust, natural precipitation is enough to make it clean as new. In addition, the membrane material has good compression resistance, so that people can "play trampoline" on it, and "it will not be crushed if a car is put on it normally". Once the adventitia breaks, according to the emergency plan, the damaged adventitia can be repaired or replaced within 8 hours. The glittering and translucent coat of "Water Cube" is also dotted with numerous white bright spots, called plating spots, which can change the direction of light and have the effect of heat insulation and astigmatism.
In addition, the "Water Cube" covers an area of 7.8 hectares without using a steel bar or a piece of concrete. Its wall and ceiling are connected by thin steel pipes, with1.2000 nodes. Only 2.4 mm thick membrane structure air pillow covers the whole building like skin. The largest air cushion is about 9 square meters, and the smallest is less than 1 square meter. Compared with glass, it can penetrate more sunlight and air, thus keeping the swimming pool at a constant temperature and saving electricity by 30%.
