Embodiment Construction
[0030] The present invention is applied to engineering example, provides a kind of new steel box girder erection method, in conjunction with accompanying drawing, specific implementation of the present invention is described as follows:
[0031] A. Construction of pile foundation (1), cap (2), pier body (3), cable tower (4), side-span concrete box girder (5) and steel-concrete combination section (6) is carried out in sequence, and the concrete box girder ( 5) The construction is completed with cast-in-place supports;
[0032] B. At the end of the bridge, use the foundation of the constructed cap (2) to install the girder door frame (Z1) that can lift the steel box girder (Z4) to the concrete beam surface of the side span in sections, and install the first to third pairs one by one during the period Stay cables (9) are tensioned symmetrically in pairs in sequence;
[0033] C. Assemble and anchor the cantilever bridge erecting machine (Z3) near the mid-span end of the concrete...
