Construction Technology of Long Span Prestressed Concrete Continuous Beam Cantilever Placement
In this paper,the application of cantilever casting construction technology in a long-span prestressed concrete continuous beam bridge is investigated.The triangular hanging basket is designed at the end of the cantilever,and the hanging basket is used as a hanger to carry out the cantilever pouring and complete the construction of the closing section,which reduces the construction difficulty and improves the construction quality.In this project,the whole process and fine management concept are implemented,and control measures are taken respectively from the erection and preloading of supports,the production and installation of hanging baskets,the binding of steel bars,the pre-maintenance of concrete pouring,the grouting of channels and the sealing of anchors to ensure the smooth completion of the cantilever construction of prestressed concrete continuous beams.
