Hollow plate girder bridge structure and construction process thereof
The invention discloses a hollow plate girder bridge structure. The hollow plate girder bridge structure comprises a plurality of hollow plate girders which are spliced together, wherein each hollow plate girder comprises a rectangular body; the top of each rectangular body extends towards the two side edges to form small cantilever arm steel bars respectively; the ends of the rectangular bodies are provided with cross beam steel bars; after the small cantilever arm steel bars of the adjacent hollow plate girders are connected, concrete is filled up, bridge deck cast-in-place joints are formed, and the adjacent hollow plate girders are connected together; after the cross beam steel bars of the adjacent hollow plate girders are connected, concrete is filled up, cast-in-place cross beam joints are formed, and the adjacent hollow plate girders are connected together. The invention further discloses a construction process of the hollow plate girder bridge structure. The hollow plate girder bridge structure is good in overall stress performance, reliably guarantees the durability of a bridge, and can be applied to a new project and used for replacing an existing hinged hollow plate girder bridge on the basis of reserving original capping beams, stand columns and other substructures.
