The steel used in the "Bird's Nest" weighs more than 40,000 tons. A high-strength steel called Q460 is used in the most stressed parts of 24 steel columns. This product, independently developed by China engineers and technicians, has an average area of 1 mm2 and can bear 46kg, which fills the gap in this technical field in China.
Covering the Water Cube is an advanced building material called ETFE, which covers an area of 6,543,800 square meters. This transparent film makes use of natural light, but it also brings difficulties: with the incidence of light, the temperature in the museum sometimes exceeds the standard. A "spot plating" technology that can reflect light independently developed by China has successfully solved this problem. Researchers distributed more than 65,438+billion circular "plating spots" on the roof and walls of the "Water Cube" according to different densities, allowing sunlight to enter according to different needs, successfully achieving a light-heat balance.
We should make rational use of modern scientific and technological achievements to make the 2008 Olympic Games a high-tech Olympic Games. It is also Beijing's firm belief to make full use of the platform for preparing for the Olympic Games and enhance the ability and strength of scientific and technological innovation.
Innovative talents in Beijing account for more than110 in China, and academicians of the two academies account for more than half of the country. How to turn resource advantage into competitive advantage? The Olympic Science and Technology Committee has been established, which is a database of consulting experts and has organized more than 400 experts in various related fields to provide all-round scientific and technological support and consulting services for the Olympic Games. The Ministry of Science and Technology has also specially set up the "Olympic Science and Technology (2008) Action Plan". In recent years, over 100 million yuan has been invested to support more than 60 key scientific and technological projects.
Create conditions to "activate" innovation ability. For the first time in Olympic history, the Beijing Olympic Games will be televised entirely through high-definition equipment. A series of new technologies, including intelligent optical networks and a new generation of wireless local area networks, will create a veritable "broadband Olympics" in Beijing. In the construction of Olympic venues, there are more than 20 new standards and norms. "These will not only become a model of similar buildings, but also a valuable legacy left by the Olympic Games."
When reporting Beijing Olympic Games, "independent innovation" is a high-frequency word. But in the understanding of Olympic builders, innovation has another deeper core: government management innovation and system innovation.
In the construction of Beijing Olympic venues, a socialized investment and financing mechanism is established, and the project legal person is determined through public bidding, and the project legal person is responsible for financing, construction and operation. Social investment accounts for more than half of the total investment in Olympic venues.
BOCOG implemented the "one-stop" service mechanism for the first time in the Olympic Games, which realized the "one-stop" completion of the acceptance, review, approval, reply, implementation and service of various administrative examination and approval applications and service demands of the media, especially overseas media.
"Enhancing the ability of independent innovation is not only related to the preparation of the Olympic Games, but also related to scientific development; It is not only related to Beijing's development stamina, but also to Beijing's historical responsibility: let innovative resources and achievements benefit the whole country, demonstrate the whole country, drive the whole country, and finally enhance the country's competitiveness on the world stage. " Beijing sees innovation in this way and promotes it in this way. This is one of the souls of the "New Olympics" and the vitality of Beijing's future scientific development.
On August 8, 2007, Beijing, east of Tiananmen Square, in front of the National Museum of China. On the countdown board of Beijing 2008 Olympic Games, the words "366 days before the opening on August 8, 2008" are particularly eye-catching. Yellow skin, white skin, black skin ... Weaving tourists compete to take pictures, leaving a bright and expecting smile on this day.
Today, one year later, the 29th Olympic Games, which attracted worldwide attention, will open a grand curtain in this ancient and young land of China for the first time. The century-old dream of the Chinese nation will finally come true.
2001July 13, Beijing successfully applied for the Olympic Games, and it has been six years since the Olympic Games were in full swing. Over the past six years, under the leadership of the CPC Central Committee and the State Council, Qi Xin, the people of the whole country, has made concerted efforts to realize national dreams and fulfill world commitments. General Secretary Hu Jintao and other central leaders have visited Beijing many times to inspect the preparations for the Olympic Games and participate in the preparations for major events. On March 23 this year, China and the Political Bureau of the Central Committee held a meeting to listen to the report on the preparations, stressing that "hosting the Olympic Games is the common aspiration of the people of all ethnic groups in China and the century-old hope of the Chinese nation"; Requirements: "We will try our best to make the 2008 Beijing Olympic Games a success."
This is the six years that Olympic builders seized the opportunity to promote scientific development and social harmony. Beijing shoulders the entrustment of the CPC Central Committee and the expectations of the people of the whole country, unites and cooperates with relevant parties, dares to innovate, strives for perfection, and promotes the preparatory work in a solid manner. Liu Qi, member of the Political Bureau of the Communist Party of China (CPC) Central Committee, secretary of the Beijing Municipal Party Committee and chairman of the Beijing Organizing Committee for the Olympic Games, said that the implementation of the strategy of "New Beijing, Great Olympics", the implementation of the three concepts of "green Olympics, high-tech Olympics and people's Olympics" and the holding of a "distinctive and high-level" Olympic Games are the process of thoroughly implementing Scientific Outlook on Development.
From energy conservation and environmental protection of venues to healthy and livable cities
-"Green Olympics" embodies the concept of sustainable development.
Strolling through Shunyi Olympic Water Park, the water is sparkling and clear as a spring against the blue sky and white clouds. The waters are surrounded by lush willows, Robinia pseudoacacia and Pinus tabulaeformis, and the beaches on both sides are covered with lawns, colorful plants and flowers. The water surface area of this venue undertaking Olympic rowing and kayaking projects is about 640,000 square meters, and the green area is about 580,000 square meters, with a green rate of over 82%. The original bare beach has become a "natural green oxygen bar".
"We strive to make Beijing 2008 Olympic Games a truly green Olympic Games," said Wan Siquan, consultant of Beijing 2008 Project Construction Command, with full confidence. "Green Olympics" runs through every link of the planning, design, construction, acceptance and operation of Beijing Olympic venues.
The recycling of water is something to be proud of in the construction of Olympic venues. In the design of the National Stadium "Bird's Nest", rainwater utilization is fully considered. The collected rainwater is used for lawn irrigation, air conditioning and water cooling, toilet flushing, greening and fire fighting in competition venues, saving nearly 60,000 tons of water every year.
The extensive use of new energy is a highlight of the Green Olympics. The Olympic Village has a 6000-square-meter solar photothermal system. Using solar energy, more than 6000 athletes will be provided with bath hot water during the Olympic Games, and more than 2000 households in this area will be provided with domestic hot water demand after the Olympic Games.
Behind the "green" venues, Beijing has more profound thoughts on the future development of the city: combining the preparation for the Olympic Games with the protection and construction of the ecological environment of the whole city, taking the green Olympics as an opportunity and demonstration to greatly improve the environmental quality of the capital and build a livable city.
In Beijing, there are two famous enterprises, one east and one west, which attract attention. In the east, the Beijing Coking Chemical Plant, which has been in operation for 47 years and once accounted for more than 80% of Beijing's total gas supply, entered the shutdown procedure. After the enterprise completely stops production, it can reduce the coal consumption for Beijing by 2.96 million tons every year; In the west, Shougang, known as the largest relocation project in the world steel history, has begun to move to Caofeidian, Hebei Province. By the end of this year, Beijing will produce 4 million tons. After the relocation of Shougang, the annual water consumption can be reduced by more than 50 million cubic meters, equivalent to 25 Kunming lakes.
Closing, stopping, moving and adjusting all focus on "green Olympics" and surpass "green Olympics". Based on this, Beijing is determined not only to control pollution, but also to create green.
The air becomes fresh. Since 1998, Beijing has continuously implemented more than 200 atmospheric environmental control measures in 10, and the atmospheric environmental quality has been improved for eight consecutive years. In 2006, the number of days when the urban air quality was Grade II or better increased from 1 0,000 days in 1998 to 24 1 day.
Green water began to flow. On the one hand, Beijing speeds up the construction of sewage treatment plants, on the other hand, it speeds up the implementation of rainwater and sewage diversion in urban areas. By the end of 2007, the rivers within the Sixth Ring Road can be basically regulated, and the water will be clear, the shore will be green and smooth, and the goal of green water around the capital will be achieved;
More lush. Mountain areas, plains and isolated urban green areas basically form three green ecological barriers. The forest coverage rate of the whole city reached 5 1%, and the ecological environment was obviously improved.
More importantly, the "Green Olympics" conveys an idea to people, that is, to advocate and cultivate a rational and healthy lifestyle.
Wang Qishan, Mayor of Beijing, said that "Green Olympics" is not only a commitment to the international community, but also an exploration of the harmony between man and nature, and between city and environment, and the pursuit of Beijing's comprehensive, coordinated and sustainable development.
From perfecting system construction to paying attention to post-game utilization
-"Thrift and honesty" shows the good image of the country.
Beijing's development achievements have attracted worldwide attention. In 2006, the city achieved a regional GDP of 787.03 billion yuan, an increase of12.8% over the previous year; Fiscal revenue reached 1 1 1.72 million yuan, up 2 1.5% year-on-year, and doubled compared with 2002.
Beijing's financial resources have greatly increased, but the account for preparatory work is getting tighter and tighter. At the beginning of the preparations, frugality and honesty in hosting the Olympic Games became the loudest slogan in the preparations. Liu Qi pointed out: "The more civilized and progressive, the more frugal and clean. We should put' frugality and honesty' throughout the whole process and all aspects of the Olympic preparations. "
Almost at the same time as BOCOG was established, the "29th Olympic Sports Committee Supervision Committee" composed of relevant state departments was announced to be established to independently supervise the preparations for the Olympic Games. BOCOG has set up a special supervision and audit department. The Beijing Municipal Government and the State Sports General Administration have also set up special supervision institutions accordingly. Government departments, districts, counties and construction enterprises also creatively do a good job in Olympic supervision and actively promote the implementation of the "Sunshine Project".
As a construction enterprise, the project supervision of Beichen Group has achieved "three no-leaks": the supervision does not miss the specialty and project, the key positions and the key personnel; The key issues of "four passes" in construction engineering group are: material suppliers are not allowed to enter the bidding scope without qualification examination and confirmation; All kinds of materials shall not enter the site without strict quality inspection. ...
Fengtai District, as a district and county government, has set up a tracking audit office for Olympic engineering construction; Shijingshan District implements the "three inspections" system for key links, extends inspections in important areas, and strengthens follow-up inspections; Chaoyang District implements the combination of industry supervision, owner internal control and social supervision to ensure the implementation of supervision.
As a contracted project, the National Stadium has completed more than 40 tenders, and the average bid price is lower than the market price of 15%- 18%, and no irregularities have been found. The National Swimming Center project has completed the steel structure, decoration works, outdoor works, elevators, air conditioners and other 16 tenders, of which the contract amount is over 100 million yuan, and no illegal acts have been found.
Greater savings are in the venues. Beijing has not only ensured the functional requirements of the Olympic Games, but also strengthened cost control. If the existing venues can be rebuilt and expanded, no new ones will be built; if temporary venues can be built, no permanent venues will be built. Among the 3 1 competition venues in Beijing, 12 is newly built, and the rest are rebuilt and temporary venues.
"Our longer-term consideration is that the construction of Olympic venues and related infrastructure can only play a long-term role and serve the future of the city if it is consistent with the overall development plan of the city." Liu Jingmin, deputy mayor of Beijing and executive vice chairman of BOCOG, said. To this end, Beijing plans some comprehensive sports facilities in areas with few sports fields, and some venues are arranged on university campuses, so that these venues will become places for community residents and students to carry out sports activities after the games. Six universities in Beijing took part in the competition.
In the functional design of venues, the development and utilization after the games should be fully considered on the premise of meeting the requirements of the games. After the Olympic Games, Beijing will rely on many first-class Olympic venues to deeply develop Olympic resources, vigorously develop modern service industries such as sports, exhibitions, tourism and information, make Beijing an important international sports event center, exhibition center and tourist destination, and further enhance the function of the capital international exchange center. This long-term plan embodies the requirements of sustainable development and is a great effort for Beijing to hold the Olympic Games frugally.
From spreading China culture to realizing people-oriented
-"People's Olympics" highlights the spirit of a harmonious society.
"Baby!" Four famous foreign expert judges of Olympic image and landscape design, including Scott givens, creative director of Salt Lake City Winter Olympics, expressed their heartfelt love for the emblem of Beijing Olympic Games, "China Seal Dancing Beijing", and they did not hesitate to praise: "A unique image with oriental wisdom!" "A flying heart, an open book about the history and culture of China."
Not only the emblem, but also the image logo of the Beijing Olympic Games, including the medal "Gold inlaid with jade" and the mascot "China Fuwa", all embody China culture and Olympic spirit, which is concise and rich in connotation. Zhang Yimou, the general director of the opening and closing ceremonies, said that the two themes of "civilization" and "harmony" will also be highlighted.
In fact, in Beijing, the understanding of "People's Olympics" has long gone beyond the scope of spreading culture. People often say that the core of the "People's Olympics" is people-oriented, the Olympics are people's participation, and the Olympic achievements are enjoyed by the people.
Beijing Olympic venues should embody humanized design as much as possible to make athletes, coaches, referees and spectators feel convenient and comfortable, and pay special attention to protecting the special needs of the disabled. The newly-built Beijing University of Technology Gymnasium will host Olympic badminton and other competitions. Badminton competition requires that the wind speed in the venue should not exceed 0.2m/s, and the designer adopts the air conditioning design of blowing air under the audience, so that cool air can be blown out from under the seats, which not only meets the needs of the competition, but also ensures the comfort of the audience.
At present, the total number of registered volunteers for the Beijing Olympic Games has exceeded 560,000, far exceeding previous Olympic Games. The "low price" policy will be implemented, and more people will have the opportunity to visit the Olympic Games. The selection of torch relay personnel is carried out in two ways: organizational recommendation and public registration. Ordinary people may also raise a burning flame ... Beijing should let as many people as possible feel the glory and dreams of the Olympic Games.
The bigger stage has expanded beyond the Olympic Games.
Liu Feng, the conductor of Beijing Public Transport Group 7 16, and his companions clean the vehicles every day to give passengers a comfortable ride environment. "Let our excellent service leave good memories for domestic and foreign guests' trip to Beijing. "
Li Shufen, a 97-year-old man from Hujialou, Chaoyang District, has created paper-cut works with Fuwa, Chinese Seal, Confucius and Li Bai as themes in the past six years, and produced more than 240 sets of paper-cut picture books. "I hope to send it to the Olympic delegations all over the world and let China's cultural image spread to the world."
"I participate, I contribute, I am happy." For a city, hosting the Olympic Games can promote the long-term development of a region. For the masses, we should also let them get benefits and happiness through the Olympic Games.
"The Olympics have not yet started, and we have already tasted the sweetness first: going to work." The 44-year-old Naheli was originally the captain of the 14 brigade in Wabian Village, Wali Township, Chaoyang District. Soon after Beijing's successful Olympic bid, their village moved to make room for the Olympic Park. According to the resettlement agreement, more than 800 people from the original 14th Brigade in Naheli, except those who retired and went out to choose jobs voluntarily, were all resettled to various departments under the Xinao Group of the Olympic Sports Engineering Construction Company, and he also served as the manager of the trade branch.
Beijingers can keep fit when they go out now. At present, the national fitness project in Beijing has covered 100% of streets, towns and qualified communities. By 2008, the allocation rate of national fitness facilities in rural administrative villages in the city will also reach 100%.
The living environment is healthier. The proportion of "blue sky" reached 66%, the forest coverage rate reached 5 1%, and the urban sewage treatment rate reached 90%. The phenomenon of littering and spitting in public places has been significantly reduced.
More importantly, Beijing's urban construction, management and service level are improving day by day, which will enable people to enjoy long-term benefits. And it will also play an exemplary role, affect the whole country and let more people share it.
Green, science and technology, humanity, honesty, frugality ... People are sharing the achievements of preparing for the Olympic Games, and people are looking forward to a distinctive and high-level "New Olympics".
Look at this. Use it if you can.
