Looking at the beautiful posture of Beijing Olympic venues and related facilities, Beijing has been shrouded in an increasingly strong Olympic atmosphere, and an Olympic city that blends ancient civilization with modern elegance is taking shape. In the preparations for the Beijing Olympic Games, in the construction of Olympic venues and related facilities, China people are working hard to realize the strategic concept of "New Beijing, Great Olympics" with their intelligence and master's attitude, relying on the three concepts of "green Olympics, high-tech Olympics and people's Olympics", which not only created a number of world-class material heritages, but also formed valuable spiritual qualities ... patriotism that won glory for our country; The dedication of hard work; Professional spirit of Excellence; The innovative spirit of climbing the peak and the team spirit of unity and cooperation.

In the recent interview of Olympic project construction, the reporter was always infected by the shining Olympic spirit of the project builders. Little by little, rivers and seas converge, and a little spark can start a prairie fire. The five spirits spread in the preparations for the Olympic Games and gathered into a dazzling and dazzling light of the Olympic Games.

As soon as we walk into the brightly lit construction site of the National Stadium, there is always a tall man who appears at all construction sites at any time. He is Qiao Feng, chief engineer of the National Stadium Project of China Consulting Engineering Construction Supervision Company.

When Qiao Feng was mentioned, colleagues couldn't help sighing: Qiao Feng had studied and worked in Japan for seven years before his successful bid for the Olympic Games, and he was well-known in the engineering supervision field. However, on the day when the "Bird's Nest" started construction, he gave up Japan's higher vocational education and high salary, returned to Beijing with his family and devoted himself to the supervision of the "Bird's Nest" project.

It was in the summer of 1993 that Qiao Feng was mentioned to study abroad. After Beijing failed to bid for the Olympic Games, Qiao Feng was filled with disappointment. Thinking of the Beijing Olympic Games in 2111, he sighed that he was not blessed to build Olympic venues. At the airport, Qiao Feng made two vows: I must return to China within 11 years; After winning the Olympic bid, I will return to China and contribute everything I have learned to my motherland.

on July 3, 2111, he heard the call of his motherland. Now he has come back and worked in the "Bird's Nest" site for three years. Looking at the rise of the "Bird's Nest", Qiao Feng's smile has a few aftertaste: I came back just to serve the motherland.

Qiao Feng is an athlete. He once hoped to be like Liu Xiang, wearing a national flag around the stadium to show the world the development and prosperity of China. Some people say that Qiao Feng was stupid to come back. He received one-tenth of his salary in the past, but he devoted ten times his enthusiasm. But Qiao Feng smiled-there was a national flag in his heart; He is wearing a national flag in his heart.

Shunyi Olympic Water Park is one of the most distinctive venues for the Beijing Olympic Games. After two years of intense construction by the builders, it has been completed and put into use a few days ago. On August 8, 2117, the Water Park will make a public appearance at the World Rowing Youth Championship and start the first shot of the 2117 "Good Luck Beijing" series of sports events.

When we stop at the only competition venue in the world, which is a combination of still water venue and slalom venue, and has the highest greening rate for the Beijing Olympic Games, people can't help asking: What is the power that turned a deserted river beach into this picturesque water sports paradise in just two years?

maybe you can see the answer from the venue builders.

Zhao Wanjiang is the on-site commander of the road and bridge construction unit of the stadium. Since the construction team entered the site for two years, the total holiday has not exceeded half a month. Due to the particularity of road and bridge construction, he has to go around the construction site four to five times a day, which is nearly 31 kilometers a day. From June 4 to June 7 this year, in order to meet the requirements of the construction period, Zhao Wanjiang and his colleagues fought continuously for 4 days and nights, and completed the last oil surface laying task of all roads in the stadium.

There are many builders like Zhao Wanjiang who devote themselves wholeheartedly to the construction site: the father of project manager Zhang Junting has been in the intensive care unit for two months, but as the project enters the closing and completion acceptance stage, he always sticks to the site and can only spend time with his father after the dead of night; Although project manager Cheng Fei lives in Tongzhou, in order not to delay his work, he has been living and eating at the construction site for two years. His 4-year-old daughter cried and called him and asked him, "When will Dad come home?" He can only hang up the phone every time ...

The office of the "2118" project construction headquarters in San

is the central office of the Olympic project. One hundred and eighty people have to face more than 1,111 projects including 31 competition venues, 45 training venues and 5 related facilities, 62 roads and 4 bridges. Since I started working at the end of 2113, the 6-day working day system has never changed. By the end of the project, many people even gave up their rest days automatically.

Perhaps "combination of static and dynamic" is the most appropriate way to describe their work. When sitting in the office, facing the intense paperwork, everyone is busy with their own affairs and has no time to talk. Out of the office, they are faced with a noisy construction site, and sometimes even if they speak loudly, the other party can't hear clearly. Many people go to sleep with their brains full of data and a hoarse voice every day.

colleagues in the safety and quality department often "give advice" to Han Gang, vice minister: there is no concept of time at work. Since taking over this job in October, 2116, others have summed up "three noes" for him: not a day goes by without coming early and leaving late, not a meal is eaten on time, there is no normal time to get off work, and overtime often exceeds 1 o'clock in the middle of the night. Han Gang said that safety and quality are very important for the Olympic construction, and now it is a critical moment, so we must redouble our efforts. Under his leadership, despite the heavy workload and pressure of the Safety Department, everyone did not flinch or complain, and completed all the work well.

under the leadership of minister ding Jianming, the technical department, in combination with the characteristics of Olympic engineering construction, conducted in-depth research, listened to opinions and suggestions extensively, and worked out the work requirements for the owners and contractors. There are 625 scientific and technological innovation projects that have been implemented or are being completed in key areas and projects, such as newly-built and temporary venues and related facilities, of which 126 are of high level, and more than 41 key training highlights and demonstration projects have been supported by special Olympic funds. The implementation of these projects will set an example for the national construction field and leave a valuable Olympic material heritage in the field of engineering construction.

Xu Bo, director of the headquarters office and secretary of the Party Committee of the government, said that the five spirits put forward by Liu Qi, secretary of the Municipal Party Committee, encouraged all cadres and workers to fight resolutely in the front line of Olympic engineering construction and accept the challenges of various arduous tasks.

Since it was started in June p>2115, the badminton hall of Beijing Olympic Games, located in the southeast corner of Beijing University of Technology, has quietly completed the construction of the world's largest dome steel structure: the dome with an inner diameter of 93 meters and an outer diameter of 98 meters, together with two wings overhanging from both sides, its steel consumption is less than 1,211 tons, equivalent to 1,111 kilograms per square meter.

Perhaps you can read from this set of data that the dome of the University of Technology is very light, although it is very large.

Dr. Liu Xuechun still remembers last year's experiment. Two months later, the model experiment not only proved the safety and stability of the gymnasium. And it shows that taking "light" can achieve better results.

In order to make the stress more uniform, the University of Technology changed the "dead buckle" at the intersection of the ring rope and the "fishing net" into a "live buckle" in the dome structure. The practice of "snap" is to divide the fixed node into two halves, the fixed part at the top is grooved, and the bottom part is made into a hemisphere. Two sets, better mechanical performance, safer for buildings.

Before this, there was no technical specification for regulating prestressed steel structures in China. With the rare opportunity of building the gymnasium of the University of Technology, Zhang Ailin and his colleagues began to write while working. In October, 2115, steel structure experts gathered at the annual meeting of the Expert Committee of China Steel Structure Association, where Zhang Ailin presented the first draft of technical regulations and universal adjustable joints. After the meeting, the old expert patted Zhang Ailin on the shoulder: "Your University of Technology has done something decent for the development of steel structure in China, which is really not easy."

According to the requirements of the International Badminton Federation, Beijing University of Technology and South China University of Technology, which is in charge of air conditioning system, should meet these conditions: in the summer of August, in a gymnasium with more than 7,111 people, the constant temperature is 26 degrees Celsius, and the air supply cannot exceed 1.2 meters per second.

the air conditioning system can't be changed, only the air outlet can be changed. South China University of Technology put forward the air supply method of "breaking the whole into parts". Air-conditioning outlets are set below the backrest of each audience, with three outlets for every two seats, and more than 9,111 outlets are set for the audience. Before the audience enters the stadium, it is necessary to cool down with large air volume, and then maintain the temperature of 26 degrees Celsius with small wind.

Standing in a hockey field as thick as a carpet, Li Xinrong, secretary of the branch of the Olympic Project Department of the General Housing Corporation, looked at the completed stadium and remembered the dilemma he faced three months ago: "At that time, municipal and on-site construction was going on at the same time, and the field was full of pits-many jobs could only be interspersed with homework, and the progress suddenly slowed down, which really made people feel anxious."

In the hockey field project department, there are 13 party member among the 16 managers. They have successively won the National May 1st Labor Award, the Capital Labor Award and the Capital Advanced Team Award for Economic Innovation. Everyone knows that Wang Xingguang's young commandos are particularly hard-working, able to tackle key problems and work well and quickly. It's really humbling to meet such a situation that you can't live.

April 1 is a Sunday, but there is no rest day for the people in the hockey field project department. At 6 o'clock in the evening, party member in the project department sat around with a heavy face in the meeting room of the temporary living area next to the hockey field site. Some people lit a cigarette in their hands, but they didn't smoke at all.

Wang Xingguang took out a small notebook and wrote down the problems he faced: 67 purchasing units, 26 professional subcontractors, 7 labor services ... all aspects should be installed, and the deadline for the delivery of the "Good Luck Beijing" series before the competition is less than 4 months.

"The construction period is already tight and the workload is too heavy. There are too many processes, and it can't be arranged. " Faced with such a short construction period and such complicated work, executive manager Niu Xiaoquan scratched his head. He is recognized as a tough guy, and he has never been soft on any construction problem. However, this time, he was deeply stressed.

nevertheless, everyone knows very well in the subconscious that there is no way out. Peng Aijing, the chief engineer of the project, took a mouthful of cigarettes and poked them in the ashtray: "If you can't discharge them, you have to do it!" I don't know what we can't do! "

the branch life meeting turned into a special meeting to tackle key problems. After more than three hours, everyone seemed to have a shot in the arm. In the subsequent construction coordination, the project department came up with an ingenious method: after each process came in, a functional room was selected for construction, and a "model room" was made. The project department then worked out the most suitable scheme according to the construction time and conditions to ensure the construction order and progress.

As a representative of the Olympic project, the Bird's Nest weaves a beautiful blueprint for China people's longing for the Olympic Games through the hands of the builders, and its sturdy bones also set up a monument to the five Olympic spirits. These five spirits are the vivid embodiment of the Olympic spirit. With the Olympic spirit, Beijing will surely contribute a distinctive and high-level Olympic Games to the world.
