Embodiment Construction

[0014] The patent of the present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0015] refer to figure 1 , the cross-sectional structure of the split-level main girder of the highway-railway dual-purpose bridge of the present invention includes a road main girder and a railway main girder 31 . The road main beam includes the left road main beam 11 and the right road main beam 12 respectively located on both sides of the railway main beam 31, and the left road main beam 11 passes through the left connecting beam 21 and the right road main beam 12. The connecting beam 22 on the right side is connected with the railway main beam 31 as a whole. There is a height difference H between the rail surface elevation 30 on the top surface of the railway girder 31 and the road surface elevation 10 on the top surfaces of the left highway girder 11 and the right highway girder 12 .

Abstract

The invention provides a highway-railway dual-purpose bridge staggered floor main beam section structure. A key structure of the highway-railway dual-purpose bridge staggered floor main beam section structure is provided, so that mutual interference generated in the train and automobile operation and maintenance period is effectively reduced. The highway-railway dual-purpose bridge staggered floor main beam section structure comprises a highway main beam and a railway main beam. The highway main beam comprises a left highway main beam body and a right highway main beam body located on the two sides of the railway main beam, the left highway main beam body is connected with the railway main beam into a whole through left connecting crossbeams, and the right highway main beam body is connected with the railway main beam into a whole through right connecting crossbeams. Height differences exist between the elevation of a railway rail face on the top face of the railway main beam and the elevation of a highway pavement on the top face of the left highway main beam body and between the railway rail face on the top face of the railway main beam and the elevation of a highway pavement on the top face of the right highway main beam body.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to a cross-section structure of a split-level main girder of a highway-railway dual-purpose bridge. Background technique [0002] With the rapid development of the national economy, the traffic flow has increased sharply. In recent years, the country has vigorously accelerated the construction of high-speed railways, expressways, urban municipal roads and urban rail transit. In order to save bridge site resources, reduce investment, and protect the environment, more and more bridges are built jointly by roads and railways (rail transit). [0003] At present, domestic and foreign highway and railway (rail transit) dual-purpose bridges basically adopt the upper and lower layer layout scheme or the road and railway level layout scheme, and the main girder adopts steel truss girder or level steel box girder layout. However, along with the continuous emphasis on the opera...
