Haikou's new landmark "Two Airlines"

Hubei Daily News (Reporter Daihui, correspondent Li Anhui, Zhu Xiao, Gao Yang) On September 27, Haikou's most high -steel structure project in Haikou City, Haikou City, was capped in the main building of the International Center of Haikou China Communications International Center.

Haikou CCCC International Center is located on the extension of the east of the CBD core area of ​​Da Yingshan CBD, Haikou. The business complex project consists of a 44 -story super high -rise main building above the ground and a 3 -story commercial podium. The total construction area is 136,000 square meters. Construction was started on May 20, 2020. It is expected to be completed in September 2023.

The main building has a construction area of ​​about 88,000 square meters and a total height of 211.6 meters. It uses steel pipe concrete frame columns+steel support inner tube+three extension truss all steel structure system. The total steel structure is about 24,000 tons. The steel beams, steel columns, and oblique supports that were made in the factory in advance were "assembled" like building blocks at the construction site. The total number of steel components reached 13,000, and only 530 steel structure joints on each floor were as many as 530.

Li Xingwang, the person in charge of the project, introduced that compared with traditional buildings, this prefabricated building greatly reduced the amount of operation at the scene, and the work efficiency increased by 3 to 5 times. Shortening the project period, belongs to the green construction building, is the new representative of the current construction industry.

Due to the complex structure of the whole steel and the high temperature and high humidity environment of the coastal coastal and high -humidity environment, the bustling section of Haikou City, the construction venue is small, the operating space is very limited, coupled with factors such as groundwater surging, sand, and difficulty in precipitation. Large, the construction of deep foundation pit has crossed 6 engineering geological layers and a geological geological layer of engineering, and has experienced support piles, engineering piles, drainage, earth -rejuvenation, internal support construction, construction of the main structure of the basement, internal support, internal support 13 procedures such as disassembling and replacement support lasted a whole year and a half.

Smart construction leads high -quality development and makes the project construction safer and more efficient. At present, 10 new technologies in my country's construction industry have applied 8 major items and 36 items in this project, including seismic, reinforcement and monitoring technology, steel structure technology, green construction technology, information technology, etc. In addition, more than 20 processes including the internal support of the construction slot steel, high -altitude welding operations, and virtual pre -assembly were applied to technical innovation or application, and successfully declared 1 invention patent and 4 new practical patents.

The Hubei Daily client, paying attention to the major events of Hubei and the world, not only pushing the authoritative policies for users, fresh hot information, and practical convenience information, but also launched a series of features such as reading newspapers, newspapers, learning, online interactives.
