Study on the Factory Prefabrication Technology of Large-Span Bridges Pier

Abstract:

The sea-crossing bridge construction takes orders the design idea of maximization, the factorization, the standardization and the assembly, which pile caps and pier shafts of the non-navigable span are prefabricated at the focus of prefabricated. In the paper, the precast solutions are put forward to pile caps and pier shafts of the non-navigable span, and the key technical problems of all kinds of precast solutions are analyzed. On this basis, the optimal pier factory prefabrication is proposed by the comparison of various schemes, which is carried out about advantages and disadvantages of prefabricated matching accuracy control, factory prefabrication, concrete placing, transport in the precast yard, transport style and the impact on follow-up construction.
