- Abstract
The complex conditions and harsh construction environment at the site of the secondary navigable span of Xiushan Sea-crossing Bridge, such as strong winds, great water depth, rapid currents, and large tidal range, brought great difficulties to the selection of cofferdams for pile caps, installation control of the cofferdams, pile cap construction and removal of suspension box cofferdam. In order to solve the technical problems in the construction of pile cap cofferdams and ensure the quality and safety of pile cap construction, an appropriate cofferdam structure was determined through hydrological survey, research and analysis. During the construction, the overall structure and detailed components of the steel box cofferdam were improved and designed innovatively. The steel box cofferdam was fabricated as an integral structure and lifted and transported as a whole, which was installed with technology of precise positioning and rapid installation to realize the rapid installation, disassembly and turnover of the steel box cofferdam, thus solving the technical problem that the lowering accuracy of the cofferdam is difficult to control due to current force and wave force.
