At 16:00 on February 16th, Beijing time, the hoisting of the main steel structure of the main steel structure installation project of the 2022 World Cup main stadium-Lusail Stadium project, which was mainly participated in by the steel structure of the China Machinery Construction Corporation, was completed, and the "saddle shape" of the building was completed. The appearance is basically formed, and major construction node breakthroughs have been achieved.
The sign of the completion of this steel structure hoisting is the closing of the pressure ring. The pressure ring is a ring of steel structure ring beams located on the outside of the project roof, with a total weight of 6,200 tons. It is the core of the project's "strength" and "beauty". Lift into place. The last section weighs 302 tons and is 37.5 meters long. The pressure ring of the Helong section needs to be at an altitude of 70 meters to ensure that the dislocation of the nozzles of the adjacent pressure rings on both sides does not exceed 3 mm and the gap does not exceed 20 mm.
As the main stadium of FIFA's top competition, it has high standards, complex design and great difficulty. The project not only needs to meet FIFA standards, but also European and American standards and Qatar's local standards. The design includes 30 majors and 42 special designs. Not only the design and management work is very complicated, but the project also brings together dozens of third-party companies such as Australia's Aureguan and British AFL, which can be called a World Cup competition for construction. The project management team has made extraordinary hardships and efforts to set up a youth commando to overcome difficulties, carry out technological innovation with the spirit of drawing a blueprint to the end, improve the hoisting process, and finally successfully complete the closing of the pressure ring.
