Largest Membrane In The Body

Located in the northern part of Doha, Qatar's capital, the lusell stadium, which tin adapt 80000 seats, is the chief stadium of the 2022 Globe Loving cup in Qatar. Information technology will undertake important activities such as the opening ceremony, final and closing ceremony, and will get an international landmark building in Qatar after completion.

At that place are 92000 seats in the stadium, 1000 more the bird's nest. The structure of lusell stadium is quite difficult. The chief body of the venue is a steel axle combined with concrete structure, with a steel volume of 100000 tons and a membrane structure of 45000 foursquare meters. It is the largest membrane structure in the world at nowadays.

The shape of lusell stadium is like a huge "golden bowl". The total steel consumption of its chief body and stand steel construction is near 30000 tons, equivalent to the weight of iii Eiffel towers. 5-pillar is an important part of the principal steel structure of the projection, with a total weight of about 6271 tons. It is the main vertical force transmission system of "golden bowl", which provides support for the compression ring and the side wall structure of curtain wall, and transmits the vertical forcefulness to the concrete column pier, and then to the ground.

Among the two enterprises that won the bid for the project, the other is Prc Railway Construction Co., Ltd., in addition to HBK, a local Qatar construction company. Russell stadium is the first earth cup main stadium built past Chinese enterprises every bit a principal contractor. The total contract value of the project is 2.8 billion QAR, about 5.17 billion yuan, about $767 one thousand thousand. China Railway Construction accounts for 45%. The total construction period of the project is 40 months.

The lusell stadium project should not only run across FIFA's specifications, merely also meet European and American specifications and Qatar's local specifications. The project also involves dozens of 3rd-party enterprises such as Australian Aurecon, British AFL and Vietnam Aurecon company, which can be chosen a world cup contest of construction. Since the offset of structure, China Railway Construction and Qatar HBK company take formed a shut joint venture to coordinate and lead the construction teams of various countries, use a big number of scientific and technological innovation achievements, overcome the bug of loftier temperature and humidity, circuitous process, cross construction, etc., and make the project motion forward steadily.

"V" ratio of one hundred ton steel structure for construction of of import joints

On May ten, 2019 local fourth dimension, the first single five-pillar of the 2022 Qatar world cup principal stadium lusell membrane construction stadium projection undertaken by China Railway Construction Corporation was successfully hoisted, marker a major breakthrough in the structure of steel structures controlling key factors of the construction period.

What about the v-pillar? Let'southward take a picture

At that place are 48 unmarried v-pillars in the projection, with a total weight of well-nigh 6271 tons. The single v-pillar lifted this time has a weight of about 147 tons, a length of about 48 meters, and a top width of most 15.5 meters. It is the largest v-pillar in lusier stadium. From viii:00 a.grand. on May 9 to ii:00 a.m. on May 10, the hoisting continued. In the process of hoisting, three technicians on site are responsible for remote control of Jack to control the length of lifting rope to ensure the smooth rotation of v-pillar in the air; four assemblers are responsible for the commodities connection between the support and v-pillar base of operations to ensure the concluding hoisting in place. Li Bai, master engineer of the project, Ma Gaofeng, deputy projection manager and other direction personnel have been squatting at the site and dispatching at any fourth dimension.

In the early morning of November 4, 2019 local time, the major construction node target was completed at lusell stadium, and the hoisting of 48 v-pillars of the master steel structure of the project was completed, laying a foundation for the subsequent of import process of drapery wall and pressure ring installation. According to Liu Dawei, the project manager, in the procedure of v-colonnade hoisting, due to the influence and brake of the steel structure construction of the stands, 44 of them accept been hoisted in late September, and the remaining iv have been equipped with hoisting conditions. The leaders and experts of the projection section consider the construction progress of the whole stadium, and decide to coordinate the construction site for the steel construction construction of the stands after word and consultation, and so as to brand 5-pillar hoisting It took a month to complete the installation process, only in terms of the full construction menses, information technology effectively saved fifteen days for the construction of the whole project.

Recently, the most important structure period node of the main steel structure of the 2022 Qatar world cup main stadium lusail stadium project undertaken by China Railway Construction International Grouping is about to be closed, and the overall "saddle shaped" appearance is nearly to be formed. Pressure level ring hoisting is the key process of the project, with tight construction flow, difficult structure organization and high safety requirements. CRCC international overcomes the impact of the epidemic, strengthens personnel resource allotment and resources scheduling, and ensures the smooth implementation of the project.
