Structure of bridge deck having polymer porous concrete surface course and construction method therefor

Abstract

The invention relates to a structure which has a polymer porous concrete face layer on bridge, comprises that plating or adhering the polymer compound formed by polymer material, or polymer and stuff, on a bridge 3 to form an adhesive layer 2, then mixing the polymer, broken stone and stuff, to form polymer porous concrete to be laid on the adhesive layer 2 to form a polymer porous concrete face layer 1. The inventive polymer porous concrete face layer has high strength, large deformation, better anti-crack property, anti-aging property and better corrosion resistance, while the adhesive layer 2 combines the face layer 1 and the bottom steel bridge 3 integrally, to bear force together, resist penetration, water and corrosion or the like.

Description

1. Technical field

[0001] The invention relates to pavement projects such as bridge deck pavement and bridge deck overlaying and construction methods thereof, in particular to the structure and construction method of polymer porous concrete surface layer on the bridge deck. 2. Background technology

[0002] 1. Bridge deck pavement and its construction method

[0003] The usual bridge deck pavement includes cement concrete pavement and asphalt concrete pavement. For the newly formed concrete bridge deck with higher rigidity, in order to further enhance the integrity of the bridge, in many cases, the cement concrete with higher rigidity or concrete with special properties is still used. The concrete with special properties includes waterproof concrete, polymer cement Concrete, polymer concrete, fiber concrete, etc. for pavement. For the overlaying of existing cement concrete pavement and asphalt concrete pavement, cement concrete or asphalt concrete is usually used as the su...
