Abstract

The invention discloses an anti-explosion anti-shock steel deck pavement structure, and belongs to the technical field of bridge construction works. The structure comprises an orthotropic steel deck plate, an Eliminator waterproof adhesive layer, a Kevlar laminated sheet, an adhesive layer, a steel fiber concrete anti-explosion layer and an asphalt concrete wearing layer which are sequentially arranged from bottom to top. A welding stud-rubber flexible combination connector is welded on the upper surface of the orthotropic steel deck plate, and reinforcing meshes are arranged inside the steelfiber concrete anti-explosion layer. The integrity of the pavement structure is enhanced by the flexible combination connector, shear stiffness is reduced, the stress state of the steel fiber concreteanti-explosion layer is improved, applicability of the deck pavement structure is improved, the reinforcing meshes, the steel fiber concrete anti-explosion layer and the Kevlar laminated sheet form aprotection structure of the deck pavement structure, and the anti-explosion and anti-shock performances of the steel deck plate and an internal structure thereof are effectively improved.

Description

technical field [0001] The invention relates to a steel bridge deck pavement structure, which belongs to the technical field of bridge construction engineering, in particular to an explosion-proof and impact-proof steel bridge deck pavement structure and a pavement method. Background technique [0002] In recent years, with the continuous improvement of bridge design theory and the continuous improvement of construction level in my country, the span and scale of bridges have been continuously improved, and long-span bridges have become the preferred bridge type in the bridge planning and design stage. The orthotropic steel bridge deck is a bridge deck structure in which longitudinal and transverse stiffeners (longitudinal beams and beams) perpendicular to each other and bridge deck cover plates are welded together to bear the wheel load together. It has the advantages of low material consumption, light weight, With the advantages of large bearing capacity, high degree of ind...
