China’s first railway bridge using gluing technology was completed on Dec 2 in Zhoukou, Central China’s Henan province, marking a breakthrough in China’s railroad construction technology.
The railway bridge is part of the high-speed line linking Zhengzhou in central China and Fuyang, East China. The bridge sections were assembled on site and stuck together with a special kind of epoxy glue, a resin that acts as an extremely strong adhesive through chemical reaction.
“Compared with the traditional construction technology of continuous beam, this technology is compact, causes less pollution and consumes less energy. It represents the future development direction of railway bridge construction in China,” said Li Aiguo, head of the Zhengzhou-Fuyang high-speed rail project.
The 277-kilometer rail has a design speed of 350 kilometers per hour and is expected to be finished in 2019.
