Wanli Yangtze River set up "the first span in the world"!Zhang Jingyao Yangtze River Bridge starts all -round construction

Inserture point News On June 28, the reporter learned from the Jiangsu Provincial Department of Transportation that another world -class cross -river project in the Jiangsu section of the 800 -hundred -mile Yangtze River, the main project of the Zhangjing -Huan Yangtze River Bridge project, started.

Zhang Jingyao's Yangtze River Bridge is the clear "Fourteenth Five -Year Plan" period in the "Fourteenth Five -Year Plan" period in the "Yangtze River Couplet Line Layout Plan (2020-2035)". Jiang Channel's key implementation projects. The project construction is of great significance for implementing the national strategy of the integrated development of the Yangtze River Delta regional and the development of the Yangtze River Economic Belt, optimizing the cross -river channel layout of the Yangtze River to improve the layout, improve the regional road network layout, promote cross -river integration and development, and build a high -level Yangtze River urban agglomeration.

The Zhangjing -yin Yangtze River Bridge is located about 28 kilometers downstream of the Yangtze River Bridge of the Jiangyin, and about 16 kilometers upstream of the Shanghai Suzong Bridge. From the intersection of the west side of the Shizhuang Town of Rugao, Nantong City, it stopped at Chenyang Interoperation of Zhangjiagang Shugang Expressway in Zhangjiagang, Suzhou, with a total length of about 30 kilometers. The construction period of the bridge is six years, and the design estimates are 311.166 billion yuan.

Zhang Jingye's Yangtze River Bridge across the river section is 7859 meters in length, with two channel bridges in the South and North, and the three sections of the south, south, and north. Among them, the southern channel bridge across the main river channel is mainly a large span suspension bridge that spans 2300 meters, and the northern channel bridge across the Rugaozhongzhong is the main span 1208 meters suspension bridge. The design is difficult, the technological content is high, and the construction technology is complicated. During the construction of the South Channel Bridge, the world's largest span suspension bridge, the highest suspension bridge pagoda, the maximum high -strength main cable, the basis of the maximum composite field anchor, the maximum continuous length steel box beam, and the maximum displacement telescopic device The world is the most "; the main cable of the main cable of the oversized suspension bridge in the structural system will achieve ultra -high steel boxes -steel pipe constraint concrete combination Sota and anchoring on the basis of the Sota structure. The foundation of the ground wall anchor, the saddle structure realizes the six "world's first innovation "".

The construction of the Zhang Jingyu Yangtze River Bridge will fully demonstrate the innovative results of the continuous exploration and breakthrough of the Chinese bridge construction in the new era. The builders of the bridge will practice new mission of transportation power, high standards and high requirements for the construction of standardization, to create new demonstrations and new benchmarks for quality engineering, and strive to achieve world -class and domestic leading goals. Sexual engineering, Chinese bridge scientific and technological innovation leads representative engineering, and the world ’s large -scale cross -suspension bridge construction milestone project". In order to accelerate the construction of a modern demonstration zone of transportation, and write a new chapter in the new chapter of the new Jiangsu modern construction of "Strong, Fu Mei Gao".

Since the implementation of the temporary project in November 2021, the Zhangjing -Hyun Bridge has been promoted in an orderly manner in order of the overall goal. The construction of temporary facilities such as trestle bridges, platforms, and crossing the river cable is basically completed. And the ground craft test test. After the main project of the bridge is fully started, it will accelerate the construction of the ground wall, the foundation reinforcement on -site process test and the infrastructure of the Sota pile during the year, and lay a solid foundation for the comprehensive completion of the wall, the Sota pile foundation, and the construction of Chengtai in 2023.

The Zhangjing -Hyuna Yangtze River Bridge is the first time that the major transportation project in Jiangsu Province has adopted the "construction and equity investment" project for the first time. It is important for innovative transportation investment and financing models, establishing a diversified investment mechanism, promoting the development of central land, strengthening infrastructure construction funding support, etc. significance. During the bidding process, the project adheres to the principles of legal person status, construction management power, construction management model, construction measurement payment model, and construction contract management framework in the construction period of the Jiangsu Provincial Transportation Engineering Construction Bureau; Change, implement the principle of "same shares and rights".
