Water-permeable concrete pavement structure

Abstract

The invention discloses a water-permeable concrete pavement structure. The structure successively comprises, from top to bottom, a nanometer-silicon-dioxide-containing colored coating layer (1), a recycled-aggregate-doped water-permeable concrete surface layer (2), a recycled-aggregate water-permeable concrete base layer (3), a water-stagnant layer (4) and a compact plain soil layer (5), wherein the coating thickness of the nanometer-silicon-dioxide-containing colored coating layer (1) is 10 to 300 [mu]m; the thickness of the recycled-aggregate-doped water-permeable concrete surface layer (2) is 100 to 200 mm; the thickness of the recycled-aggregate water-permeable concrete base layer (3) is 150 to 200 mm; the water-stagnant layer (4) is a waterproof geotextile layer or an ordinary concrete layer, and the thickness of the ordinary concrete layer is 30 to 50 mm; and the compaction coefficient of the compact plain soil layer (5) is greater than 95%. The water-permeable concrete pavement structure provided by the invention has good mechanical property and water permeability; the surface layer is coated with nanometer-silicon-dioxide-containing colored coating through spraying, so wear resistance of the structure is improved; meanwhile, the water-permeable concrete pavement structure has sterilization and self-cleaning effects, is environment friendly and comfortable and has elegant appearance.

Description

technical field [0001] The invention relates to the field of permeable concrete pavement structures, in particular to a recycled aggregate permeable concrete pavement structure whose surface is sprayed with nano-silica-containing color paint. Background technique [0002] The application of permeable concrete pavement structure is becoming more and more extensive, which has given birth to a group of personnel who specialize in the research, design and construction of this special concrete. With the deepening of research, the mechanical properties and water permeability have been able to meet the needs of various light-loaded road surfaces through certain mix ratios and structural measures. At present, more and more scholars have begun to pay attention to multifunctional permeable concrete, and the requirements of low carbon, environmental protection and ecology have become a dominant direction. For example, can the natural aggregate in the permeable concrete pavement st...

Problems solved by technology

This patent uses luminous permeable concrete as the surface material, which is very novel in form, but its soil foundation is relatively weak, and a large amount of rainwater seeps down and easily hollows out the soil particles, which affects its durability.
