The construction of the world's highest bridge tower in Zhangjinggao, East China's Jiangsu province, was completed on Oct. 21, marking the completion of piling construction.
The construction of the south main tower and auxiliary tower of Zhangjinggao Yangtze River Bridge started on July 29 with 138 steel protective tubes. There are 97 of them in the south main tower, with a single steel sheath about 45 meters long, 3.2 meters in diameter and 78 tons in weight. The second shipping board of pay in the construction process, the project team and zhangjiagang maritime safety administration, the bridge headquarters pioneer "Bridges" party alliance, such as overall planning, on command, overcome the river flood season the withered, secondary dredging, high-temperature heat, typhoon and cold wave hit bad impact on the environment, solve the water level is too low and the difficulty of the ship ran aground, positioning, a series of problems, It has completed the manufacturing, transportation and construction of all steel protective cartridges with good quality and quantity, laying a good foundation for the subsequent pile foundation construction.
Connecting Suzhou, Taizhou and Nantong, Zhangjinggao Yangtze River Bridge spans 7,859 meters across the river. It is divided into the south passage bridge, the North passage bridge and the approach bridge. Among them, the South Passage Bridge is a super long suspension bridge with a main span of 2300 meters, which is the largest span bridge in the world.
