Imprinted water-permeable cement concrete ground structure with aggregate exposed on surface, and manufacturing method thereof

Abstract

The invention discloses an imprinted water-permeable cement concrete ground structure with aggregate exposed on the surface. The structure comprises components of, from top to bottom: a cement water-permeable concrete layer, a bedding layer and a base layer. The layers are orderly arranged from top to bottom. Patterns and textures are formed through an imprinting technology on the upper surface of the cement water-permeable concrete layer with an aggregate exposure effect, wherein the cement water-permeable concrete layer is the top layer. The manufacturing method of the ground structure comprises steps that: (1) the base layer is paved; (2) the bedding layer is paved on the base layer; (3) at least one cement water-permeable concrete layer is paved on the bedding layer; (4) the patterns and textures are formed through imprinting on the surface of the top cement water-permeable concrete layer; (5) an aggregate exposure treatment is carried out upon the surface of the imprinted top cement water-permeable concrete layer. The aggregate exposure treatment comprises specific steps that: a surface-setting-retarding material is sprayed on the surface of the imprinted top cement water-permeable concrete layer, or a cement-setting-retarding film is coated on the surface of the imprinted top cement water-permeable concrete layer, then the surface of the imprinted top cement water-permeable concrete layer is washed; or the surface of the imprinted top cement water-permeable concrete layer is directly washed, such that the aggregate exposure effect is realized. The method also comprises a step (6), which is a maintenance step. The imprinted water-permeable cement concrete ground structure with the aggregate exposed on the surface is both an environment-friendly ground structure and a decorative ground structure.

Description

technical field [0001] The invention relates to a surface-exposed aggregate embossed permeable cement concrete ground structure and a manufacturing method thereof, belonging to the technical field of pavement pavement. Background technique [0002] At present, the outdoor integral pavement art floor widely used in the market mainly includes embossed floor and permeable floor. The styles and colors of the embossed ground are changeable, with strong decoration and artistry; the permeable ground with exposed aggregate has high bearing capacity, high water permeability, ecological environmental protection, supplements groundwater, reduces urban heat island effect and has high safety in rainy and snowy weather. Safety and appearance are natural and simple. However, embossed floor products are impermeable pavement materials and processes, which cannot achieve water-permeable effects. At the same time, embossed floors are artificially colored, which is not natural enough to achieve...

AI Technical Summary

Problems solved by technology

The styles and colors of the embossed ground are changeable, with strong decoration and artistry; the permeable ground with exposed aggregate has high bearing capacity, high water permeability, ecological environmental protection, supplements groundwater, reduces urban heat island effect and has high safety in rainy and snowy weather. Safety and appearance are natural and simple. However, the embossed floor products are impermeable paving materials and processes, which cannot achieve water-permeable effects. At the same time, the embossed floor is artificially colored, which is not natural enough to achieve realistic effects.

Although the exposed aggregate permeable floor has good environmental performance and natural texture, its decorative and artistic effects are limited to a certain extent because its surface is made of coarse aggregate and has no shape.
