| description | The invention discloses a rapid construction method of a prefabricated segmental beam, and aims to solve the technical problems of a prefabricated segmental assembled bracket system with the height of8m or unbalanced load and a bracket body supporting technology in the construction of a ramp bridge with a smaller radius. The rapid construction method of the prefabricated segmental beam comprisesthe following steps that after a foundation is treated, performing measurement and positioning; arranging a disc buckle support; laying main ridges and secondary ridges, and placing jacks; carrying out a preloading test on the stent system; performing primary settlement observation on the prefabricated segmental beams before and after suspension splicing; after settlement stabilization, performingpermanent prestress strand pulling, tensioning and pressure drop of the top plate are conducted according to design; completing permanent prestress construction of the roof; after tensioning of the prestressed steel strands is |
