Abstract:In recent years, in water project construction, traditional construction techniques can no longer meet the demands of the projects, and there is an urgent need to strengthen the application of new technologies, new processes and new materials. Starting from the construction technology of Bailey support for cast-in- place beams in water projects, this paper makes a analysis of how to solve the support problem of cast-in- place bridge beams when water operation cannot be avoided. It also introduces the advantages of the Bailey support, as well as its technical application and construction key points, take the reference for other similar projects.
