The steel structure of the main stadium of the 2022 World Cup contracted by Chinese enterprises was

The hoisting of the main steel structure of the main stadium of the Qatar World Cup undertaken by our country has been completed.

The steel structure of the main stadium of the 2022 World Cup has been completed, and since the completion of the construction of our Chinese railway, the exterior of the building has been mainly built to achieve the normalcy of the bottom node. In November 2016, a consortium was established to lay the foundation for the next step in the construction of the roof structure. This is the first time that a Chinese company has broken the monopoly of European and American companies in this field and successfully established the main stadium of the World Cup as the main contractor.

As the main venue of the 2022 World Cup, it will host major events such as the opening and closing ceremonies, semi-finals, and finals, with a total capacity of 92,000 spectators, 1,000 seats more than the Bird's Nest, and the largest and most professional stadium.

The total consumption of steel is equivalent to 3 iron towers, and the roof membrane structure covers an area of 56,000 square meters, making it the largest structural construction project in the world. The top competition of the main stadium at the construction site of the Qatar 2022 World Cup main stadium is a model of modern building technology, and European and American standards meet the needs of both parties locally in Qatar. 42 specialty-designed specialties.

China's railway construction industry chain, the use of Chinese enterprises to collect, design management, steel structure, membrane structure roof cables, etc., the difficulties and special tasks not only break through Australia and the United Kingdom, Turkey and other countries dozens of enterprises to participate in the project, packaged in the construction can be called the World Cup competition.

The indication of the completion of the steel structure hoisting is the closure of the pressure ring, which is the ring of the steel structure ring beam on the outside of the roof of the project, which will be partially lifted during the construction process. After the closure of the dragon, all 24 segments of the pressure ring form a whole, which plays the role of fixing the roof cable and transferring the roof load to the lower steel structure, which is the most important steel structure component of the project. The project manager said that the 23 segments in front of the pressure ring were hoisted to the intended position.

The weight of the final section is 302 tons, and the gap of no more than 20mm is 3mm.

China's steel is of high quality, with professional designers to design and guide the construction of stadium structures, and the business level is high.

China mobilized a lot of manpower and material resources, and worked 24 hours a day in three shifts to build the steel structure of the main stadium.

This is the speed of China, which amazes the world, China's engineering construction process is standardized, down-to-earth and serious, which is inseparable from our culture, we pay attention to hard work, practical and hardworking, rather than all kinds of human rights in Western countries first, no overtime, no rush, and afternoon tea every day.

China's manufacturing technology is still very strong, although there are still certain defects in some places, but in some large companies, it can still show China's manufacturing technology.

This can ensure the early opening of the entire Four Bridges project on the basis of quality and safety, ensure the continuous deepening of economic and trade cooperation between China and Kuwait, and maintain the friendship between the two peoples.
