The 2022 Qatar World Cup has begun. Although the Chinese men’s football team missed the competition, “Made in China” has played an important role in this world competition. From small souvenirs and daily necessities to large buses and stadiums, China-made World Cup-related products have covered the international engineering industry, new energy vehicle industry, sporting goods industry, cross-border e-commerce industry, light industry, etc. Among them, China’s steel-related products appeared in the World Cup venues, and once again demonstrated the extraordinary strength of “Made in China” on the world stage!
Jinggong Steel Structure Group builds the “Golden Bowl” of Qatar World Cup
As one of the most watched events of all mankind, Qatar has built and renovated eight top-level stadiums for this World Cup. Among them, the steel structures of Lusail Stadium and Laiyang Stadium, the main venues of the World Cup, were constructed by Jinggong Steel Structure Group located in Keqiao, Zhejiang. Lusail Stadium is currently the world’s most advanced World Cup football stadium with the most complex structural system and the highest construction requirements. Jinggong Steel Structure Group overcame various challenges such as climate, technical difficulties, and epidemic situation, perfectly completed the construction task, and contributed Chinese strength to the holding of international events.
Lusail Stadium, located in Lusail New City, Qatar, looks like an Arabian “golden bowl”, shining on the Persian Gulf. The construction of this giant Arabian “Golden Bowl” is extremely difficult. Due to the “Golden Bowl”‘s unusual structure, large span, and heavy structural modules, it has brought huge challenges in technology and construction. The steel structure weighing more than 20,000 tons is supported on the concrete column only by 24 spherical joint bearings. After the installation of the 1,000-meter-long pressure ring truss is completed, the size deviation of more than 100 cable clamp holes on it is required to be controlled within 25mm. Construction is very difficult.
The total steel structure consumption of Lusail Stadium is about 30,000 tons. This is currently the largest professional stadium with the largest number of people built overseas by Chinese companies. The steel structure is divided into 48 pieces of V-column trusses, 24 pieces of pressure ring trusses, and 48 pieces of curtain wall trusses. After being assembled on the ground, they are hoisted into place by thousand-ton crawlers. The on-site modular hoisting used 3 large crawler cranes, 1000 tons, 1250 tons and 1650 tons respectively. The V-pillar truss needs to be adjusted from lying on the ground to the designed bowl-shaped posture, the adjustment of the suspension rope exceeds 10 meters, and the heaviest unit of the pressure ring truss reaches 480 tons. Jinggong Steel Group uses 5G technology to remotely control to ensure that each component is precisely in place.
Shanghai Construction Engineering Steel Structure participated in the construction of the 2022 Qatar World Cup venues, and digital technology created a “diamond in the desert”
Among the 8 World Cup stadiums, there is a stadium with a unique shape and magnificent colors, known as the “Diamond in the Desert”. It was constructed by Shanghai Construction Engineering (Jiangsu) Steel Structure Co., Ltd. Qatar Education City Stadium.
As the general contractor of the steel structure construction of the stadium, Jiangong Steel Structure has undertaken all related tasks such as steel structure design, 3D modeling, processing and production, and on-site installation, and participated in the management consulting work of some engineering projects. The digital technology, innovative technology, and international team of Jiangong Steel Structure have laid a solid foundation for the completion of the entire stadium in June 2020, becoming the first stadium completed in this World Cup.
Digital pre-assembly is an important means to ensure project quality. After technical research, the construction steel structure project team determined the methods of single-piece data collection, overall digital pre-assembly, 1/4 box girder arc section physical pre-assembly and digital assembly verification, effectively solving the most critical box-shaped ring beam The problem of dimensional accuracy ensures a successful on-site installation. During the process, the construction steel structure also used digital typesetting technology, ERP management system, digital simulation packing technology, two-dimensional code coding technology, etc., so that digital project management runs through all links. The project team also developed the manufacturing and assembly technology of large box-shaped ring beams, and the technical scheme of end milling in the process of V-shaped ring beams.
The Education City Stadium adopts environment-friendly solutions to the maximum extent in terms of design, raw materials, and manufacturing processes. It is the first World Cup stadium to obtain five-star certification from the Global Sustainability Assessment System (GSAS). A model of engineering development. Qatar Education City Stadium is another successful masterpiece of Shanghai Jiangong Steel Structure’s “World Quality Steel Structure Project”.
Nanjing Iron and Steel Co., Ltd. assists in the construction of World Cup venues
In 2018, Nangang won the steel for the stadium construction project of the 2022 Qatar Football World Cup again. It is understood that the European standard structural steel exported from Nangang to Qatar is mainly used in the construction of AlRayyan Stadium and Lusail Stadium in Qatar.
Al Rayyan Stadium, Qatar: Al Rayyan Stadium currently has 21,282 seats, which will increase to 44,740 by adding upper seats using a modular structure. The stadium uses a special “media film” that acts as a display screen showing news, updates and game progress. The total steel consumption is about 9,000 tons, and the construction area is 43,627 square meters.
Lusail Stadium, Qatar: Both the 2022 World Cup opener and final will be held at this stadium. Located in the city of Lusail, the Leuser Landmark Stadium is inspired by the sails of a traditional Arabian dhow and surrounded by water. The total steel consumption is 20,000 tons, the construction area is 144,151 square meters, and the total number of seats is 90,000.
From the perspective of time series, from the 1980s to the beginning of this century, the construction, operation and brand activities of the World Cup were mainly undertaken by enterprises in Europe, America, Japan and South Korea. Chinese manufacturing has reached the world’s leading level, has a certain overseas competitive advantage, and is shining in the international market.
