Steel bridge deck pavement structure for ultra-large span

Abstract

The invention provides a steel bridge deck pavement structure for an ultra-large span. The steel bridge deck pavement structure comprises an anti-corrosion layer, an elastic transition layer, polymerprefabricated profile layers and an anti-sliding layer which are all sequentially paved on a steel bridge deck; a bonding layer is arranged between the elastic transition layer and the polymer prefabricated profile layers; the elastic transition layer and the anti-sliding layer are both of an integrally-formed structure; the specification of each single macromolecule prefabricated profile layer is1-12 m long and 0.5-1.8 m wide; the adjacent macromolecule prefabricated profile layers are connected in a lap joint or clamping connection mode; and the surfaces of all the macromolecule prefabricated profile layers after being connected are located on the same plane. With the steel bridge deck pavement structure, in a using process, no matter a steel bridge deck is disturbed by dynamic load change of the bridge deck or wind power, distortion and buckling deformation of the steel bridge deck cannot be caused, and the problems of the distortion and buckling deformation of an ultra-large-spansteel bridge deck in the using process are ingeniously solved.

Description

technical field [0001] The invention belongs to the technical field of steel bridge deck pavement, and in particular relates to a steel bridge deck pavement structure for super-large spans. Background technique [0002] At present, there are more or less problems with the asphalt pavement structure of all steel box girder bridges in my country, especially for some long-span and super-long-span heavy-duty bridges. Generally, some bridges need to be repaired almost every year. In the steel bridge deck pavement structure, epoxy asphalt mixture, as a thermosetting material, plays an extremely important role. It has excellent high temperature stability and mechanical properties, and especially has good resistance to load deformation at high temperatures It has been widely used in the pavement structure of many long-span steel box girder bridges in China. However, this kind of steel bridge deck pavement structure with epoxy asphalt mixture has the disadvantages of high brittlenes...
