Taizhou Yangtze river bridge is another extra-large span bridge after the completion of Jiangyin bridge and Runyang bridge in Jiangsu province. The total length of the bridge is 62.088 kilometers, and the whole project adopts the standard of two-way six-lane expressway. The total investment is 9.37 billion yuan, and the construction period is five and a half years. The main bridge (2x1080 meters) is a three-tower, double-span, steel box girder suspension bridge, which ranks first in the world. Meanwhile, the middle tower adopts longitudinal herringbone and transverse portal frame steel tower, and the large segment manufacturing and installation technology are first used in China.
Taizhou Yangtze river bridge, as a three-tower suspension bridge, has achieved the three “most” in terms of design and technology at home and abroad, and set five “World First” records in bridge construction: the long suspension bridge with three towers and two spans (2x1080 meters); the longitudinal herringbone, transverse door frame steel tower (200 meters high); the sinking depth of caisson foundation in the middle tower; the length of “W” shape main cable erection; the steel girders of two suspension Bridges are hoisted synchronously and symmetrically.
The technicists of Dynatronic assist the Highway Dep. of the Ministry of Transport in carrying out a number of tests on Taizhou bridge by using the special test system for Bridges. Faced with the inspection of a bridge with five world records, the difficulty is far greater than that of ordinary bridge. In order to successfully complete the inspection task, the two sides work closely, and carefully prepare the test plan to achieve every test detail. Overall, the test of Taizhou bridge is another milestone in the history of extra-large bridge test in China.
Obviously, a new cross-river highway has been completed in the central part of Jiangsu. Taizhou bridge has strengthened the transportation links between Taizhou, Zhenjiang and southern Jiangsu, and improved the expressway network of Yangtze river delta region, providing more powerful support for the coordinated development of regions along the river.
