Abstract

The invention discloses a bridge girder erection machine for overall erection construction of the upper structure of a large-span bridge and a construction method thereof. The bridge girder erection machine comprises a main truss arranged in the longitudinal bridge direction, a lifting device connected with the upper end face of the main truss in a sliding mode, a front support fixedly arranged at the front end of the main truss in the longitudinal bridge direction and a supporting leg system connected with the main truss in a sliding mode. The supporting leg system comprises a plurality of supporting legs, any supporting leg is of a telescopic structure and is provided with a driving device, and the driving device drives the supporting leg to slide on the main truss in the bridge erecting direction; and the multiple supporting legs are alternately fixed to support the main truss, and driving devices fixed to the supporting legs drive the main truss to advance for multiple spans in the bridge erecting direction. Multi-span steel beams can be erected at a time, the bridge erecting effect is improved, and the stability of the bridge girder erection machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction. More specifically, the present invention relates to a bridge erecting machine and a construction method for integral erection of the superstructure of a long-span bridge. Background technique [0002] In recent years, the national infrastructure construction and the construction of ecological civilization have been promoted simultaneously. Bridges require less land than roadbeds, so they are widely used. The requirements for the area occupied by the substructure of bridges are further reduced, which promotes the development of bridges in the direction of large spans. In the category of long-span bridges, girder bridges are more economical structural types. Prestressed concrete structure and steel-concrete composite beam structure can be selected as the superstructure type of beam bridge. There is an upper limit for the maximum span in the design of prestressed concrete beams, so the ...
