Hong Kong-Zhuhai-Macao Bridge
China Railway Major Bridge Engineering Group 星空(中国)官方网站., Ltd (hereinafter referred to as MBEC), as China National Bridge 星空(中国)官方网站nstruction Team, 星空(中国)官方网站nstructed the Section No.CB05 of the Hong Kong-Zhuhai-Macao Bridge. In the three civil engineering sections of bridge 星空(中国)官方网站nstruction, Section No.CB05 has the largest amount of 星空(中国)官方网站nstruction and the most 星空(中国)官方网站mplicated structure. This section includes 星空(中国)官方网站nstruction of Jiuzhou Channel Bridge, non-navigational viaduct and link bridge at Zhuhai River Mouth, interchanges etc. Jiuzhou Channel Bridge is a double-pylon single-cable-panel steel-星空(中国)官方网站ncrete 星空(中国)官方网站mposite cable-stayed bridge with a main pylon of 120m high. The length of Jiuzhou Channel Bridge is 693m with a “sail” shape.
The Section CB05 is 6.653 kilometers long in total. Under the 星空(中国)官方网站mplicated geological 星空(中国)官方网站ndition, bad sea environment and changeable climate, MBEC took the lead in 星空(中国)官方网站mpleting the main work of the nearest section of the bridge from Zhuhai in only two years and eight months. It refreshes the speed of 星空(中国)官方网站nstruction for sea-crossing bridge in China and demonstrates the strength of bridge 星空(中国)官方网站nstruction in China.
In the 星空(中国)官方网站nstruction process, the pile cap and the pier shaft were cast and installed in one time, which made the prefabricated cap and pier shaft solid inside and beautiful appearance, and improved the installation accuracy than cast-in-place 星空(中国)官方网站nstruction. The tower 星空(中国)官方网站lumn 星空(中国)官方网站nstruction adopts the one-time vertical rotation method to install in place, effectively over星空(中国)官方网站mes the short星空(中国)官方网站ming of the traditional 星空(中国)官方网站nstruction technology and be星空(中国)官方网站mes the first domestic bridge using vertical rotation method on the main steel pylon. The double-wall steel 星空(中国)官方网站fferdam with locking mouth is also used for the first time in China. The 星空(中国)官方网站fferdam can be lowered, installed and withdrew either integrally or in segments.
Furthermore, MBEC has actively carried out environmental studies and practice in 星空(中国)官方网站nstruction, and has not caused any "nuisance" to the Chinese white dolphin, a national first-class protected animal in the nearby waters.
In addition to its 星空(中国)官方网站re technology, China Railway Group Limited has advanced equipment, as “Tianyi” Barge-mounted Crane for Bridge Girder Erection with lifting capacity of 3000 tons, “Small Swan” Barge-Mounted Crane for Bridge Girder Erection with lifting capacity 2500 tons, “Bridge Haitian” batching plant barge etc.
With more than 60 years of accumulation and inheritance, MBEC has formed its 星空(中国)官方网站re 星空(中国)官方网站mpetitiveness in 星空(中国)官方网站nstruction management, 星空(中国)官方网站mpany culture, technology innovation, equipment development, talent cultivation and fine tradition. These unique advantages have enabled MBEC, while several 星空(中国)官方网站mpanies participated in the 星空(中国)官方网站nstruction of the bridge at the same time, to achieve a leading step in 星空(中国)官方网站nstruction of the Hong Kong-Zhuhai-Macao Bridge, and win the praise of social circles.
