Key Techniques Introduction to Maputo Bridge Steel Box Girders Construction

摘要

Maputo Bridge in Mozambique is the largest suspension bridge under construction in Africa, which adopts a double-pylon single-span steel box girder structure with a main span of 680m. The superstructure steel box girder construction faces a series of obstacles. By researching and applying the key construction techniques, such as whole-section factory manufacturing, all girders one-time ocean shipping, complex environment wharfing and lifting, new rotating cable crane erection and site connection, and etc., the project achieved the purpose of period guarantee, quality control, environmental impact reduction and suspension bridge construction technology promotion. Furthermore, it is expected to provide a reference and engineering example for similar large-scale bridge projects in the future.
