Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] The present invention is a bridge structure, which mainly includes a foundation 4, a bridge pier 1 arranged on the foundation, and a box girder 2 placed on the bridge pier 1, and is characterized in that the box girder on the upper part of the bridge is an arched single-box multi-chamber Concrete box girder, the pier cross bridge at the lower part of the bridge is provided with an upward column 6, which is a Y-shaped, II-shaped, H-shaped pier or a vertical II-shaped, H-shaped pier, and the lower part is a vertical column. Straight or outwardly curved. During the implementation, the arched single-box multi-chamber concrete box girder is a simply supported beam or continuous beam structure of reinforced concrete or prestressed concrete prefabricated components or cast-in-place components. The inclination angle of the stressed member of the bridge ...

Abstract

The invention discloses a bridge structure, mainly comprising: piers arranged on the bases, box girders arranged on the piers. It is characterized in that: the top box girder of the bridge is an arched single-box multi-chamber concrete box girder; the bottom pier cross bridge is arranged with an upward column; the top part of the column is a pier column of abducted curved or straight Y type, I I type and H type; the bottom part of the column is straight or abducted curve. The technical characteristics of the invention are: firstly, the structure of the bridge is harmonious, reasonable and the appearance is elegant; secondly, the bridge span is enlarged, and the arched box girder can be preformed or on-site casting according to the bridge width, span and situations of the construction site, by which the project time can be shortened and the effect to the traffic is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of bridges involved in civil engineering, in particular to a bridge structure with arched box girders plus curved or vertical piers and a construction method thereof. Background technique: [0002] Urban traffic viaducts play an increasingly important role in urban daily traffic. At present, the piers of urban traffic viaducts that have been implemented in my country are in the shape of a single or double column in a straight line in the direction of the bridge, and the distance between the piers is generally between 20-30m. , the form of the main girder is hollow plate girder, T beam or box girder with straight web and oblique web, and the entire viaduct structure is single in shape and has a long construction period. Invention content: [0003] The purpose of the present invention is to provide an improved bridge structure, which can meet the requirements of urban modernization, so that the viaduct can f...
