"The maximum height of the pylon of Huajiang Canyon Bridge is 261.7 meters, and the installation of reinforcement is a difficult point in the construction of the bridge. Through technological innovation, the modular lifting appliance of main reinforcement+stirrup is used to achieve accurate docking, improve efficiency and reduce the safety risk of aerial work. In addition, in the construction of cable tower, the whole support system adopts special Bailey truss and load-bearing corbel for special design, and innovatively realizes the construction beam of large-span pier free support system.

"As a" second-generation road ", from the world's highest bridge, the Beipanjiang Bridge on Hangzhou Ruili Expressway, to the current Huajiang Canyon Bridge, it is a great honor and pride to participate in the construction of such a world-class bridge. After more than 20 years of work, it has witnessed the tremendous changes in Guizhou's transportation construction.
