Scene of the ceremony
On November 2, the second phase of Ningbo Zhoushan Port Liuheng Highway Bridge project, jointly undertaken by the Group and China Railway Construction and Bridge Bureau, started, marking that the construction of this world-class cross-sea bridge project has entered the full construction phase. Mr. Wang Lixin, Member of the Standing Committee of the CPC Committee and Vice President of CRCC, attended the commencement ceremony and made a speech. Mr. Chen Tao, Party Secretary and Chairman of CRCC, and Mr. Wang Yongdong, Vice General Manager of CRCC, attended the ceremony.
Wang Lixin speaks
Ningbo Zhoushan Port Liuheng Highway Bridge Phase II project is a major infrastructure connecting Liuheng, Meishan and other important islands in Ningbo-Zhoushan Port sea area. The project starts from the southwest of Liuheng Island and passes through Liuheng, Fodu and Meishan three independent islands from east to west. The total length of the line is 18.78 kilometers, which is built according to the standard of two-way four-lane expressway with a design speed of 100 kilometers per hour.
CCTV financial channel "ZhengDianfinance" column reported the Liuheng highway bridge construction of the second phase of the news
As a large-scale cross-sea island connecting project, this project is composed of many Bridges and connecting lines. The span of Shuangyumen Super Bridge is 1,768 meters, which is the largest single-span steel box girder suspension bridge in the world and also the largest span cross-sea bridge in China. Once completed, it will refresh the largest span of cross-sea bridge in China. Qinglongmen Bridge is the world's longest three-tower steel box girder cable-stayed bridge, with two main spans of 756 meters across the Qinglongmen Channel. The main tower is a diamond-shaped steel concrete bridge tower with a height of 249 meters.

The project construction scale is large, structure types are many, high science and technology content. The whole line connects 3 independent islands, crosses 4 reclamation areas and crosses 2 straits. The length of the bridge in the whole line is about 9 kilometers, and the amount of offshore work is large. The meteorological, hydrological and geological conditions in the project construction area are complicated, and the shipping is busy, making it difficult to organize the offshore construction.

In this construction, the construction team of the Group and China Railway Construction Bridge Bureau will for the first time adopt the design concept of the left and right allogenic expansion of basic gravity anchorage structure adapted to the ridge landform of the sea islands, and innovate the application of the construction technology of ultra-small clear distance tunnel anchor on the island of the super-large cross-sea suspension bridge, so as to improve the construction efficiency on the basis of meeting the use function.
Iron building pile 01 Apply the first pile
During the organization and construction of the bridge, the construction team will adopt factory manufacturing, assembly construction, intelligent construction and information management to build "one platform and five systems", that is, the control platform integrating BIM, 5G, technology and security, environmental perception, real-time monitoring and other systems, and unlock the intelligent construction engine with the customized "iron construction scheme" to help the construction of two world-class Bridges.
The successful contract of the project fills the gap in the performance of the long-span bridge of China Railway Construction Corporation and marks a new history in the construction of the cross-sea bridge of China Railway Construction Corporation. The implementation of the project will provide important support for the brand construction of "highway and super large bridge" of the Group company, and will have a positive and far-reaching impact on the improvement of the overall management level of the Group company, the improvement of scientific and technological innovation ability, and the construction of the cadre and talent team.
The first pile 01 is finished
The project department will rationally arrange the construction according to the guiding ideology of "overall planning, scientific organization, focusing on the first, stage development, balanced production and orderly promotion", committed to overcome the technology of long-span deep-water bridge, cast high-quality projects, create a first-class bridge construction brand, promote the "water in one year, two years of sealing, three years of closing, four years of completion, The overall project planning target of five years' completion has been achieved.
Bridge drawing three-dimensional space, open up the economic artery. Ningbo Zhoushan Port Liuheng Highway Bridge Phase II project is the only channel connecting Ningbo to Zhoushan Liuheng Island, which is an important measure to implement the national strategy of "One Belt, One Road" and "Yangtze River Economic Belt". It will effectively promote the construction of national Marine economy development demonstration zone and national New area, further improve the external traffic conditions of the islands south of Zhoushan, and optimize the spatial layout of Zhejiang Zhoushan Islands New Area. We will build a modern Marine industrial base, and realize interconnected development of port areas and industries on the three islands of Liuheng Island, Fodu Island and Meishan Island.
