Based on the construction project of a 600 m concrete filled steel tube rigid arch bridge, the key technologies such as the cable hoisting system, as well as the design and pouring scheme for external concrete are introduced. For the cable hoisting system, a “combined temporary with permanent” design between the suspension tower foundation and the bridge pier foundation is adopted. A new cable lifting system and comprehensive monitoring techniques are employed to ensure the safety of the cable hoisting system for the large span. The rigid arch ribs use the optimization control principle of “optimal process, controllable results” and one tension technique, thus,to achieves a joint elevation error less than 2 mm in the connection of chord pipes. The external concrete formwork follows the “3 rings, 6 segments and 8 working faces” balanced loading construction process, which ensures that the maximum tensile stress of the external concrete and the shape of the main arch meet the requirements.
