China News Service, Beijing, April 8 (Xu Jing) The reporter learned from the Beijing Municipal Major Project Office on the 8th that the steel structure construction of the Beijing Workers Stadium Reconstruction and Reconstruction Project (hereinafter referred to as "Xingongti") has been successfully completed, and the grand dome has been completed. Appearance.
After being fully completed in December this year, Xingong Sports will undertake the opening and closing ceremonies of the Asian Cup from June to July 2023, and will host the event as the final venue.

The shape of the "worker bowl" is basically presented
Zhao Lei, person in charge of the renovation and reconstruction project of the Beijing Major Project Office, said that the renovation and reconstruction of the industrial body follows the design principle of "modern venues with traditional appearance". The three characteristic elements of the façade form and proportion remain unchanged, continuing to present the solemn and elegant style and urban memory of the top ten buildings in the capital in 1959.
With the successful completion of the construction of the steel structure, the shape of its main shape, the "worker bowl", has basically appeared.
In the next step, Xingongti will continue to promote the construction of the main body of the football field, the commercial area and the municipal supporting facilities, improve the work related to the integration of the subway, strengthen the improvement of the surrounding environment, and do a good job in the reconstruction of the artificial lake and the reconstruction of sculptures. The facade curtain wall construction will be completed, the subway integrated construction will be completed by the end of October, and the completion acceptance conditions will be met in November.

The new canopy has six functions
The addition of a canopy is one of the highlights of this renovation.
On the morning of the 8th, the reporter saw at the renovation site that the huge steel structure dome had completely spanned the top of the stadium.
Li Xiajie, deputy manager of Beijing Construction Engineering Group's work-body reconstruction project, introduced that the total steel consumption of the entire canopy steel structure is about 16,400 tons, which is a veritable "steel giant bowl".
In response to the difficulty of hoisting large components to a maximum of 46 meters, the project specially used the 1250-ton crawler crane that debuted in Beijing for hoisting; in view of the difficulty of overwintering and long-term low-temperature welding during the construction period of the steel structure, the construction unit The low-temperature welding test at minus 20°C was carried out in Yanqing and Zhangjiakou in advance, and the technical breakthrough was finally completed, which ensured the construction quality of the project.
It is understood that this canopy has six functions, including shading, lighting, water supply and drainage, snow melting, photovoltaic power generation, and sound absorption and noise reduction, which enhances the sound absorption effect in the venue, and at the same time improves the ability of the new workers to hold the competition and view in extreme weather. match experience, and meet the requirements of the Asian Cup and future higher-level international football competitions.
The outer ring of the canopy is set with a surrounding photovoltaic power generation area. The photovoltaic power generation system will provide part of the electricity for daily operation in areas such as the football field and the underground supporting garage, enabling the green development of the city.

Bowl-shaped grandstand takes into account both earthquake resistance and aesthetics
The Xingongti is centered on fans watching the game. The stand adopts the most advanced "stand bowl" structure in Europe. The original two-story "disk-shaped" stand has become a four-story "bowl-shaped" stand.
The slope of the stand is increased, and the audience's field of vision is wider.
In addition, Xingongti also set up the North Stand as a stand for die-hard fans, which is expected to accommodate 15,000 people. Whether it is the national team or the club, they can obtain the greatest support belonging to the home court in Xingongti.
In order to protect the original appearance of the work body, its height and radian are strictly controlled, the height of the main building cornice is moderately increased, and the roof canopy adopts the form of a single-layer arch shell steel structure with a large opening space.
On the premise that the seismic fortification intensity of buildings in Beijing area reaches 8 degrees, the visual effect and aesthetics are taken into account.

Create a new business card for the capital
Turf is the core facility of a professional football stadium. In this aspect, Xingongti directly benchmarks the World Cup stadium and the professional football stadiums of the five major European leagues, and adopts the anchor grass system that has become mainstream in the top European leagues.
Anchored grass system is a combination of natural grass and artificial grass to ensure that the turf is maintained at the best standard throughout the year.
In addition to adopting the highest standards in raw material procurement, the new industrial turf system is also designed and configured with a powerful "turf maintenance system" under the turf.
According to Meng Fanwei, manager of the comprehensive management department of Zhonghe Industrial (Beijing) Commercial Operation Management Co., Ltd., this system is like a rainbow cake, consisting of multiple underground structural layers such as rapid drainage, automatic sprinkler irrigation, low-temperature heating, and vacuum ventilation.
In the event of heavy rainfall, the drainage system can quickly drain the accumulated water in the venue to ensure that the normal performance of the athletes will not be affected. There is also a special water collection facility under the lawn, and the collected rainwater can be recycled again. Combined with the hot and humid summer in Beijing The weather characteristics and the design of the turf below the water level, the underground ventilation system is configured to ensure the air circulation of the turf micro-environment and ensure the healthy growth of the turf.
When encountering low temperature weather in winter, the lawn heating system will also help the growth and maintenance of turf.
To ensure that the high quality of turf is maintained throughout the season, the upgraded new body has introduced a turf supplementary lighting system.
The system allows the turf to get enough light throughout the year, especially in winter, it can form a synergy with the geothermal system to maintain the ideal state of the turf all year round and ensure top quality throughout the year.
Zhao Lei said that Xingongti can not only successfully complete the task of hosting the Asian Cup, but also provide a perfect venue for future home games of Beijing Guoan and even higher-level international football events in the future, making Xingongti a true showman.” A world-class professional football field”, and with this as the core, it will be built into an open urban public space without walls.
The reconstructed Gongti will become a comprehensive consumption carrier integrating sports, shopping, leisure, culture, entertainment and other functions, and the capital's "urban landmark, cultural and sports business card, and vitality center".
