Workers hoisted on Monday the steel truss beams for the main channel of Changzhou-Taixing Yangtze River Bridge, the world's largest span railway and highway cable-stayed bridge under construction.
In the waters on the Taixing side of the Changzhou Taixing Yangtze River Bridge, as the four main hooks of a 2500-ton floating crane vessel slowly lifted, a 1400-ton steel truss beam was steadily lifted and finally placed on the top of the No. 3 pier, which is 50 meters high from the river surface.
“The height of this section is 15.5 meters, the length is 21 meters, the width is 35 meters, and the total weight is 1400 tons, equivalent to the weight of 900 cars. The lifting of the first section marks the full entry of the superstructure construction of our main channel bridge,” said Wang Hui, the Executive Deputy Manager of Changzhou-Taixing Yangtze River Bridge Project of CCCC Second Harbor Engineering Bureau.
The main channel bridge adopts a double main truss "N" shaped steel truss beam, with a total of 91 large sections, of which the heaviest beam section reaches 1865.5 tons. After the completion of factory manufacturing, the entire section of steel truss beam is transported by waterway to the bridge site for overall hoisting and erection.
The main channel bridge of Changzhou Taixing Yangtze River Bridge, with a main span of 1176 meters, is the largest cable-stayed bridge under construction in the world for both highway and railway, and is also the first bridge on the Yangtze River integrating expressway, intercity railway and first-class highway.
