Problems solved by technology

[0002] Generally, steel box girders are used as overhead bridges to meet the interchanges of urban railway business lines and urban roads. Therefore, the bridge device and construction method based on the combination of concrete box girder and steel box girder is an important civil engineering component. In the existing concrete-based In the bridge device and construction method combining box girder and steel box girder, a plane support is still carried out through the bridge pier. Since the bridge pier belongs to one point support, it affects the stability of the bridge across the railway business line

Abstract

The invention discloses a bridge device based on the combination of a concrete box girder and a steel box girder and a construction method. The bridge device comprises a bridge device body provided with a concrete box girder (6) and a steel box girder (7). A V-shaped pier (3) is connected with the concrete box girder (6) or the steel box girder (7) and provided with supporting inclined strip partswhich are distributed in a branched mode. Through the bridge device body, crossing of a railway service line is achieved, through the V-shaped pier (3), divergence face supporting of the bridge device body is achieved, plane supporting is not conducted through piers any more, and therefore the bridge stability performance of crossing the railway service line is improved.

Description

technical field [0001] The invention relates to a bridge device and a construction method, in particular to a bridge device and a construction method based on the combination of a concrete box girder and a steel box girder. Background technique [0002] Generally, steel box girders are used as overhead bridges to meet the interchanges of urban railway business lines and urban roads. Therefore, the bridge device and construction method based on the combination of concrete box girder and steel box girder is an important civil engineering component. In the existing concrete-based In the bridge device and construction method of box girder and steel box girder combination, a plane support is also carried out through the bridge pier. Since the bridge pier belongs to one point support, the stability of the bridge across the railway business line is affected. Contents of the invention [0003] The object of the present invention is a bridge device based on the combination of concr...
