's maritime bridge built tunnel construction technology." According to reports, the Hong Kong-Zhuhai-Macao Bridge, the first three places cooperation to build a very large project; the design life of the bridge for 120 years, is the world's bridge design life of the longest; the construction of the bridge is three places for the first time a unified international construction standards. Tan Guoshun said Railway Co., Ltd. won the bid in bridge civil engineering and composite beam construction sections, general manager of the different legal systems, different management system, different technical specifications for the construction of the Hong Kong-Zhuhai-Macao Bridge to bring difficulties and challenges. " , "but the same dream, the same pursuit of the same faith we have the determination to overcome difficulties and meet the challenges of confidence." It is understood that China Railway Group Limited in the country, building various kinds of Bridge over 1500 seat, and has involved in the East China Sea Bridge, the Hangzhou Bay Bridge, the construction of the Qingdao Bridge.

At present, the construction of the new standard for Hong Kong-Zhuhai-Macao Bridge, the new requirements and a number of indicators of the "first", the China Railway Bridge Bureau Group research team focused on to solve the related construction will be faced with a series of world problems. In order to solve prefabricated Cheng Taiwan installation key technology, the China Railway Bridge Bureau Group under the Chinese Academy of Engineering, Chief Engineer of the Corporation Qin along the whole of the leadership of Zhongshan base repeatedly carried out studies and simulation test, at present has successfully completed a "foot foot sealing simulation test, hanging and wave forces impact the process study and a series of construction technology used for the first time in the world. According to this cross-sea bridge design, construction steel pipe pile verticality requirements in less than 1/250, China Railway Bridge Bureau Group of independent research and development to meet the requirements of the adjustable guide frame. According to reports, the main project of the Hong Kong-Zhuhai-Macao Bridge the Zhuhai wiring will be six-lane expressway standard construction, designed driving speed of 100 kilometers per hour. Completed, the project will build the Hong Kong-Zhuhai-Macao traffic channel to enhance the leading role of Hong Kong to the Pearl River east coast regional economic radiation to fully tap the potential for development of the Pearl River West, the transport links between the convenience Hong Kong, Macao and the Pearl River.
