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...

AI Technical Summary

Problems solved by technology

[0008] The cement concrete pavement used in conventional concrete bridge deck pavement has high rigidity and poor driving comfort. Usually there is no adhesive layer, and the interface is easy to peel or peel off

The properties of the usual asphalt concrete bridge deck pavement are unstable, and the interface bond is also easily damaged, which is prone to early failure

The polymer cement concrete used in some concrete bridge deck pavement is to mix polymer, cement, continuous graded gravel, sand, etc. evenly to form dense polymer cement concrete. Poor comfort, using conventional cement concrete construction technology, poor surface flatness
