Project Name: Hezhou Station Extra-Large Bridge on the Zhuhai–Zhaoqing High-Speed Railway

Project Location: Zhuhai, Guangdong, China

Product Used: Type 400 Bailey Panels

Project Overview: Using extra-large Bailey truss assemblies, the structure is formed by combining multiple rows and layers of Bailey panels to create a high-strength load-bearing frame, providing reliable temporary support for high-speed rail box girder erection. The Bailey support system must withstand the self-weight of the box girders and construction loads, demanding extremely high overall stiffness and stability, representing a large-scale application of Bailey structures in the high-speed rail engineering sector. Standardized Bailey panels enable rapid assembly and precise positioning, adapting to the long-span, high-load requirements of high-speed rail bridges, effectively improving girder erection efficiency and construction safety. Serving as a temporary load-bearing platform for high-speed rail box girder erection, the Bailey support system resolves the load-bearing challenges of in-situ casting or segmental assembly of long-span box girders, serving as a critical temporary structure ensuring construction quality and schedule of high-speed rail bridges.
