Abstract

The embodiment of the invention provides a bridge rotation construction device and method, and the device comprises a central rotating body mechanism which is disposed below a mid-span pier of a beambody, supports the beam body and a pier below the beam body, and drives the beam body and the pier to swivel; an auxiliary slideway mechanism which is used for being arranged below the side span of the beam body and is in an arc shape with the center rotating body mechanism as the circle center; and an auxiliary walking mechanism which is used for being arranged at the bottom of the side span of the beam body; wherein the auxiliary walking mechanism can walk along the auxiliary slideway mechanism. According to the bridge rotation construction device and method, the problem that in a traditional scheme, bridge consolidation design is difficult can be solved.

Description

technical field [0001] The application relates to bridge construction technology, in particular to a bridge swivel construction device and construction method. Background technique [0002] The bridge swivel technique is to turn the bridge pier as a central axis to the design position after the bridge pier and girder structure are constructed. Operation of railway lines. [0003] Beams are divided into concrete pouring beams, simply supported beams, truss beams, etc. Taking truss beams as an example, in order to ensure the stability of the rotation, the piers and beams must be consolidated. However, the consolidation design is more difficult for truss girders with high overall stiffness, weak local member stress, and free end cantilever length exceeding 130m. If the consolidation treatment fails to meet the design requirements, it will affect the stability of the bridge during the rotation process. Contents of the invention [0004] In order to solve one of the above-me...
