Orthotropic steel bridge deck paving structure and construction method thereof

Abstract

The invention discloses an orthotropic steel bridge deck paving structure and a construction method thereof. The orthotropic steel bridge deck paving structure sequentially comprises a steel bridge deck plate, a rubber layer and an aluminum alloy surface layer which are disposed from bottom to top. The rubber layer is disposed between the steel bridge deck plate and the aluminum alloy surface layer. Anti-shear welding studs are welded on the surface of the steel bridge deck plate at the same interval. An epoxy resin adhering layer coats the upper surface of the steel bridge deck plate. The rubber layer is prefabricated in factories and used for preventing water, insulating heat, buffering loads, providing a construction platform, and the like. Equal-distance holes corresponding to the anti-shear welding studs on the steel bridge deck plate are reserved in the lower surface of the rubber layer, equal-distance holes corresponding to anti-shear protruding nails on the lower surface of the prefabricated aluminum alloy surface layer are reserved in the upper surface of the rubber layer, and field construction is facilitated. The orthotropic steel bridge deck paving structure has the advantages that the rubber layer is good in load bearing and load transfer performance and good in bridge structural deformation compliance; the construction speed and durability are increased.

Description

technical field [0001] The invention relates to the technical field of traffic engineering, in particular to an orthotropic steel bridge deck pavement structure and a construction method thereof. Background technique [0002] The steel bridge deck is welded and fixed on the orthotropic structural beams and longitudinal ribs, and the steel deck system is flexible and easy to bend. The deformation and stress characteristics under the action of vehicle load and temperature load are very obvious compared with ordinary cement concrete bridges. In different parts of the same bridge, the deformation and stress are also very different. At present, there is no generally effective theory and method for the design of orthotropic steel deck pavement. The existing high-temperature pouring asphalt pavement technology has poor high-temperature stability and is easy to form ruts. The impact of the high temperature of the mixture on the bridge during construction cannot be ignored. The exis...

[0002] The steel bridge deck is welded and fixed on the orthotropic structural beams and longitudinal ribs, and the steel deck system is flexible and easy to bend. The deformation and stress characteristics under the action of vehicle load and temperature load are very obvious compared with ordinary cement concrete bridges. In different parts of the same bridge, the deformation and stress are also very different. At present, there is no generally effective design theory and method for orthotropic steel bridge deck pavement.

The existing high-temperature mixing and pouring asphalt mixture pavement technology has poor high-temperature stability and is easy to form ruts. The impact of the high temperature of the mixture on the bridge during construction cannot be ignored

The existing epoxy resin asphalt mixture pavement technology has strict requirements on the construction environment, the construction is difficult, the maintenance time is long, the surface is smooth, and the driving safety in rainy days is poor
