ABSTRACT
Taking the Daqingzhou bridge as the background, the construction technology of a double-layer cast-in-situ beam in a deep water area is studied. A rotatable support system is designed. It not only solves the problem of space collision between steel support and deep-water cofferdam, but also ensures that a set of support is shared during the construction of double-layer cast-in-situ beams. The calculation of the finite element method provides a technical guarantee for construction. The engineering practice shows that the designed support system meets the specification requirements, which provides some practical experience and reference value for similar projects in the future.
