Environment-friendly breathable concrete road surface structure

Abstract

The invention discloses an environment-friendly breathable concrete road surface structure. A soil base layer is included. A gravel layer is arranged at the upper end of the soil base layer. A reinforced concrete layer is arranged at the upper end of the gravel layer and internally provided with strengthening ribs arranged in a crossed manner. A water discharging layer is arranged at the upper endof the reinforced concrete layer. A water guiding layer is arranged at the upper end of the water discharging layer. Water guiding cavities are symmetrically formed in the water guiding layer. The side walls, close to the water guiding layer, of the water guiding cavities are internally provided with branch cavities in the vertical direction, the branch cavities communicate with the water guidingcavities, the ends close to the water discharging layer are obliquely arranged downwards, and the upper end of the water guiding layer is provided with a high-permeability concrete layer. By means ofthe environment-friendly breathable concrete road surface structure, the phenomenon of road surface water accumulation can be effectively prevented, long-time rainwater accumulating is avoided, rainwater discharging and dredging hindering is avoided, and therefore frequent maintenance is not needed in the usage process, the usage process is safer and cleaner, and maintenance is more simple.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an environment-friendly breathable concrete pavement structure. Background technique [0002] Permeable concrete is developed and used by Europe, America, Japan and other countries to address the defects of the original urban road surface, allowing rainwater to flow into the ground, effectively replenishing groundwater, and alleviating some urban environmental problems such as the sharp drop in the city's groundwater level. And can effectively eliminate the environmental pollution hazards of oil compounds on the ground; at the same time, it is an excellent pavement material that protects groundwater, maintains ecological balance, and can alleviate the urban heat island effect; it is conducive to the benign development of the human living environment and It is of special significance in urban rainwater management and water pollution prevention and control. The permeable...

Problems solved by technology

[0004] However, after the existing permeable concrete is laid, if the accumulated water in the pavement cannot be diverted to the drainage channel in time, the soil subgrade will be corroded and the road surface will be affected. Therefore, the streets and pavements in major cities can only be continuously maintained and removed. Resurfacing; in summary, this kind of road surface not only has relatively large defects, but also consumes more costs in later maintenance
