Steel bridge deck pavement structure with composite three-dimensional porous material and its construction method

Abstract

The invention discloses a steel bridge deck pavement structure made from composite three-dimensional porous materials. The steel bridge deck pavement structure comprises a pavement layer which is arranged on a steel bridge deck and formed by mixing a composite three-dimensional porous material with a filler, wherein three-dimensional through holes of the three-dimensional porous materials are filled with the filler to form a network-woven compact structure; and the through holes of the three-dimensional porous materials are densely filled with the filler to enable the materials and the filler to penetrate and cross mutually as a whole, the filler can form looping lockout in the three-dimensional meshes, so that a good enhancement effect is achieved, the strength of the interfacial binding force is high, the materials are restrained by each other and enhanced by each other, the formed structure has strong integrity, the strength and yielding stress of the structure are obviously improved, the whole strength and rigidity of the steel bridge deck pavement structure can be improved, the steel bridge deck pavement structure has certain tenacity, the anti-track capacity can be enhanced; the steel bridge deck pavement structure has the characteristics of being small in water absorbance, good in seepage resistance and freezing resistance, high in wear resistance and good in high and low temperature resistance performances, and the technology for implementing the steel bridge deck pavement structure is simple and convenient to operate.

Description

technical field [0001] The invention relates to the field of bridge deck pavement, in particular to a steel bridge deck pavement structure with composite three-dimensional porous materials and a construction method thereof. Background technique [0002] Along with the process of my country's reform and opening up, expressways, urban expressways, and urban arterial roads have developed rapidly, and a large number of highway bridges and urban bridges have been built. So far, all kinds of modern bridges that have been built in our country have entered important positions in the world's bridge span rankings, even among the best. It reflects the development height of my country's production, economy, science and technology from one aspect. [0003] With the vigorous development of bridge technology in our country, the bridge construction technology is becoming more and more mature, and the problems in the overall structure of the bridge are decreasing day by day. Relatively spe...

Problems solved by technology

However, the durability of asphalt concrete bridge deck pavement is seriously insufficient

Usually the total length of structural structures such as bridges, passages and interchanges on an expressway is usually much shorter than that of the subgrade pavement, but the asphalt concrete surface layer on the cement concrete pavement of the structures on most expressways produces potholes The number is often more than the potholes produced on the subgrade road surface, the repair rate of the former is often much larger than that of the latter, and it is more prone to rutting and pushing
