Li Xiaohuai, director of the project department of Hefei Olympic Sports Center, knows every detail of this big project that cost 850 million yuan and lasted for 26 months. Can the new stadium host a golden league-level event so that Liu Xiang can "fly" in Hefei once? Guo Can Jingjing sealed the world again in Hefei Diving Hall? Can China Table Tennis Dream Team Defend National Honor in Hefei Complex? Director Li Xiaohuai assured us that all this is possible, because every venue is designed according to international standards, and the soft and hard conditions are fully capable of hosting various international individual events. "Hefei Olympic Sports Center has perfect functions and complete equipment, many of which are national first-class or even unique. In addition to its smaller scale, its design concept can be compared with the venues of the Beijing Olympic Games. "
2 The lawn is divided into cold and warm areas to understand the wind direction.
The main stadium, which can accommodate 60,000 people, is the most spectacular building in the Olympic Sports Center, including the outfield training ground and the infield main stadium. Now the outfield is being paved with turf, and the infield is being paved with plastic track. "The grass species suitable for the growth of cold and warm climate are selected for both the internal and external venues. The warm-season turf is planted in the external field and the cold-season early bark is planted in the infield, which ensures that the stadium can undertake competitions in any season." Construction direction: Hefei Olympic Sports Center was designed by Academician Ma, one of the only two academicians in China.
In addition to the "backup" of football turf, almost all main stadiums designed according to IAAF standards have "two systems". Whether it is the throwing area of discus and javelin or the bunker for long jump, it is divided into south and north areas, and competitions can be held in any area. "This is mainly because of the wind direction problems that may be encountered during the competition. We can choose different competition areas to minimize the influence of wind direction on athletes' performance. "
On July 19, technicians from Italy were carefully pasting the plastic track imported from Italy on the black asphalt of the main stadium. The laying of the plastic runway is expected to be completed within 40 working days. At that time, the 10 standard runway that fully meets the requirements of the IAAF will be presented to people.
3 "Rotating Torch" shows the beauty of flame.
The three main buildings of Hefei Olympic Sports Center are egg-shaped main body and flight auxiliary body.
In the modern Olympic Games, it is essential for the main stadium to light the main torch, and the unique design of the main torch platform often becomes a symbol of a city sports center. A 68-meter-high main torch was designed on the north side of the main stadium of Hefei Olympic Sports Center. The hollowed-out metal components made the torch shine. It is particularly worth mentioning that this torch designed by Beijing Institute of Civil Engineering and Architecture is very unique, and the ignition process will give people a feeling that the fire is spinning and burning, which fully shows the charm of the flame. It is understood that the torch is fueled by natural gas and is expected to be put into trial operation at the end of August.
The main entrance of the east gate of the main stadium is also unique. When holding a large-scale event, the spectators entering the stadium from the main entrance of the East Gate will walk along a viaduct with a length of 190 meters and a width of 33 meters. "After completion, there will be a 190-meter-long and 4-meter-wide Avenue of Stars decorated with lights on the viaduct." Director Li Xiaohuai said, "Ordinary viewers can feel the star-like feeling when they walk through such an aisle.
The public can share the "warm-up pool"
Hefei is a city of science and education, and the construction of the Olympic Sports Center also shows people the charm of science and technology everywhere.
The Olympic Sports Center Complex can accommodate 6000 people. Different from the transparent natural lighting design of the diving hall, the complex is all illuminated by artificial light sources. "Don't underestimate the lighting design in the museum, that is, to ensure enough brightness to ensure that athletes will not be dazzled by the lights during the competition. The requirements are very high. " Director Li Xiaohuai told us that it took two years to design and debug the lighting of the comprehensive hall, and then all 240 light bulbs were debugged strictly according to the specified angle. "Now it can be guaranteed that every inch of the competition area in the complex has sufficient lighting, and there is absolutely no shadow!"
Walking into the newly-built swimming pool, the audience can only see a standard swimming pool and a 6-meter-deep diving pool. Diving pool has10m, 7.5m, 5m and 3m standard platforms and springboard for competitions, and the audience position is relatively high. This design ensures that athletes can watch easily even if they compete on the platform of 10 meter. The most amazing thing is that there is a warm-up pool with five standard tracks and a depth of1.8m hidden under the high auditorium. When there is no competition, the warm-up pool will be open to the public for fitness. In addition, it is worthy of children's happiness that there is a foot-shaped children's play pool next to the warm-up pool.
5 elevator for the blind shows humanistic care
Hefei Olympic Sports Center is not only a work of art made of solid cement, but also embodies a strong human touch and humanistic care.
On both sides of the viaduct of the main stadium, and on each side of the gymnasium and diving hall, the builders set up four square columns with steel frames. "This is the outer frame of the elevator. We will install four vertical elevators, mainly to provide services for the blind, so that blind friends who want to' listen' to the game can easily enter the stadium. " At the entrance of the east gate of the main stadium, a long zigzag ramp is designed on the north side of the steps leading to the viaduct, which provides convenience for the wheelchair-pushing audience.
The athletes' passage, the judges' passage, the reporters' passage and the spectators' passage seem to be a small maze inside each venue entering the Olympic Sports Center. "According to the requirements of modern stadiums and gymnasiums, different people set up different dedicated passages without interfering with each other." Director Li Xiaohuai showed us several facilities specially serving journalists: there are 277 press seats in the main stadium, and independent press release halls, press release halls and other special places are set up in all three stadiums to help journalists release news through the Internet and other means at the first time. The reporter even had a special small staircase leading to the stadium and VIP passage, which really surprised everyone.
