Light permeable prefabricated foamed concrete footpath pavement structure

Abstract

The invention discloses a light permeable prefabricated foamed concrete footpath pavement structure. The light permeable prefabricated foamed concrete footpath pavement structure comprises inverse filtering geotechnical cloth paved on a plain soil foundation, a fine sand bedding layer paved on the inverse filtering geotechnical cloth, prefabricated permeable foamed concrete paved on the fine sand bedding layer, anti-crack permeable geotechnical cloth paved on the prefabricated permeable foamed concrete, macropore bituminous stabilized macadam paved on the anti-crack permeable geotechnical cloth, and a permeable bituminous mixture paved on the macropore bituminous stabilized macadam. The footpath pavement structure has the functions of permeating, storing water and purifying water, the self-weight of the prefabricated foamed concrete is relatively light, the prefabricated foamed concrete has an excellent effect of dispersing the load, the stability of the foundation subgrade soil immersed in water is guaranteed, and the footpath pavement structure has a wider application scope than a common permeable footpath pavement structure.

Description

technical field [0001] The invention relates to the field of walkway structures, in particular to a prefabricated foamed concrete lightweight permeable walkway pavement structure. Background technique [0002] Urban sidewalks are one of the important components of urban roads. The traditional non-permeable sidewalk pavement is discharged through the rainwater collection well through flooding. The sidewalk is slippery, and the accumulated water can easily make pedestrians wet their shoes, which affects the safety and comfort of pedestrians walking; lack of regulation of urban surface temperature and humidity capacity, exacerbating the urban heat island effect; blocking the groundwater recharge path, which is not conducive to the growth of green plants. [0003] Since urban footpaths are mainly responsible for pedestrian traffic, the requirements for carrying capacity are lower than those for motorways, so it is easier to put forward more functional requirements for them besi...

AI Technical Summary

Problems solved by technology

[0004] In order to maintain the hydrological environment of the original soil, the disturbance to the original soil should be minimized in the process of laying the pavement structure of the permeable pavement, and the bearing capacity and stability of the soil foundation will be reduced in the state of water retention
