Longitudinal pushing structure of closure segment of continuous rigid frame bridge
The invention discloses a longitudinal pushing structure of a closure segment of a continuous rigid frame bridge. The longitudinal pushing structure comprises a left main girder and a right main girder, wherein left pushing support components are fixed on the left main girder, right pushing support components are fixed on the right main girder, the left pushing support components and the right pushing support components are connected in a pushing manner through pushing components, the left pushing support components are fixedly connected with the top surface of the left main girder, and the right pushing support components are fixedly connected with the top surface of the right main girder. According to the longitudinal pushing structure disclosed by the invention, steel plates do not need to be pre-buried in the end surface of the left main girder and the end surface of the right main girder to be used for welding the pushing support components, and main reinforcements do not need to be cut off at the places where the steel plates are supposed to be pre-buried in the top surface of the left main girder and the top surface of the right main girder, so that the connection of prestressed bellows is not influenced, the operating space can be greatly enlarged, the operating difficulty is greatly reduced, the pushing efficiency is greatly improved, the mounting work and the disassembling work of the pushing support components are greatly simplified and are convenient, and the time consumed in the pushing process is short.
