"Water Cube" blue water can drink

National Swimming Center "Water Cube" pool has been filled with water. At present, the "Water Cube" internal decoration is nearing completion. "Good luck Beijing" China swimming open will be held from January 31st to February 5th. By then, the water cube will be officially unveiled. Last week, the reporter walked into the "Water Cube", personally feel the uniqueness of this great building.

Far see: "heaven" can not fall down

Reporter witnessed: 10 am, the reporter approached the water cube". This square building, the outer layer is covered with a blue "bubble". The sun in the morning on its body, and not far from the bird's nest each other, a spectacular. In the water cube around 20 meters, with a full circle of high fence of 2 meters, there is a circle of a width of 6 meters deep in the moat of 0.5 meters, armed police patrol back and forth, it seems to want to touch the blisters, is impossible.

Experts decrypt: "Water Cube" dimensions of 177 x 177 x 30 meters, are used in the design of the bubble theory, exterior distribution of 3000 irregular air pillow, like ETFE film a "water bubble" (poly tetrafluoroethylene copolymer) has good extension and compression, each film can bear the weight of a car, heavy rain, hail, sandstorm is no problem.

In addition, ventilation, fire protection, sound insulation, cleaning and other problems are solved successfully, which is worth mentioning is that the cleaning using the siphon principle, rain fall naturally, can play a role in cleaning, which can recycle rainwater.

The film itself has a certain thickness, but if deliberate destruction will rupture. However, a small area of damage will not affect the entire bubble, special adhesive tape can be easily repaired. Around the moat, in the winter will be used to ensure that the ice does not freeze.

So far, "Water Cube" envelope only one case accident: a bird with his food, his shadow saw the film, that companion snatch, jumped a peck, "Chi", membrane leakage. However, the film can be filled, re inflated, the film inside the air pressure system can also guarantee that the sky can not fall down".

Close look: numerous steel H

2O water molecule

Reporters witnessed: from Simon into the "Water Cube", it is found that there are a total of three Hall, left by the warm-up pool, pool game is composed of two parts, and the right is reserved for a water recreation center, Olympic Games, ordinary people can swim in the "water cube". What is interesting is that most people think that "bubble" only in the "Water Cube" of the external wall, but in fact, into the "Water Cube" after the discovery, look up to the inner wall is also covered with water blue bubbles, very beautiful. Although there is no light, but the natural light through the plastic film, the room is still bright.

Subsequently, the reporter in the professional under the guidance of the "Water Cube" came to the roof, close to see support from thousands of "bubble" of the steel structure, they are perplexing, spectacular, magnificent, very irregular, of different sizes. It's like the structure of H2O water molecules learned in middle school chemistry.

Experts decrypt: "Water Cube" steel structure for the new polyhedron space steel structure". With the overall weight of light (the total amount of 6900 tons of steel, the amount of steel per square meter is only about 120 kg), span large (maximum span of 130 meters) characteristics. The adjacent bird's nest reached 20000 tons of steel. In contrast, the water cube is clearly more energy savings. "Water Cube" is the 20000 member of the entire structure, the 10000 balls, each node, each rod is completely different. For the completion of the implementation of the drawings there are more than 30 thousand, light drawing drawings, it took about a year. Workers in welding, there is no reference, completely relying on drawings and accumulated experience to complete the work. In addition, due to the "Water Cube" by the film special materials and related technology, the use of natural light to every venue lasted 9.9 hours, one year, 80000 square meters of the "Water Cube" will save a lot of power resources.

Look: blue water can drink

Reporter witnessed: from the water cube roof down around two bends, came to the Olympic swimming, diving and other projects in the competition hall. The left and right sides have 8500 audience seats, very beautiful. Of course, here is the most memorable, or a swimming pool and a diving pool, blue water, very beautiful, as if into a world water world. As the film coat for light almost no barrier, bright sunlight directly sprinkled in the venue, clear blue water looks at the bottom. Standing in the pool, because the water quality is particularly good, strong refraction, looking at the pool of water, feeling only a few dozen centimeters distant.

Experts decrypt: swimming pool water volume is 3750 cubic meters per day, also need to supplement the water of 112.5 cubic meters to 187.5 cubic meters. The pool of water storage capacity has reached 3660 cubic meters, coupled with the need to warm up the pool of water storage capacity of 2500 cubic meters, the whole water cube is recognized as large water consumption.

Such a huge amount of water, alone Beijing municipal water supply pipeline is not enough. "Water Cube" there are two other ways to get water: rainwater reuse and water reuse. Rainwater reuse is used to collect rainwater, drainage, storage, disinfection, reuse, mainly used for air conditioning cooling water supply and outdoor landscape water. The use of water is to treat athletes and other waste water treatment for ground washing and outdoor greening irrigation.

In addition, the swimming pool, all with recycling, in order to ensure the quality of water cube to achieve the new fina health standards, the water will be used sand
