Description

TECHNICAL FIELD

[0002] Pervious concrete is also called porous concrete, sandless concrete and pervious pavement. It is a kind of porous lightweight concrete made of aggregate, cement, reinforcing agent and water. It does not contain fine aggregate.

[0003] Pervious concrete has a honeycomb structure with evenly distributed holes formed by the mutual adhesion of a thin layer of cement paste on the surface of coarse aggregate. It has the characteristics of air and water permeability and light weight.

[0004] In related art, a pervious concrete structure is disclosed in Chinese Patent No. CN215482045U. When in use, the structure ensures the structural strength of the road surface bottom foundation through the plain soil tamping layer 1, thereby ensuring the stability and service life of the road surface. When it rains, the rainwater first penetrates into the pervious concrete layer and then into the gravel layer. The particles of the first-grade gravel are relatively large, and the gaps between the first-grade gravel are relatively large, thereby better allowing the rainwater in the pervious concrete layer to flow downward. The rainwater flows through the second-grade gravel, reducing the flow speed of the rainwater and avoiding the impact of the rainwater on the plain soil tamping layer. The rainwater flowing into the gravel layer passes through the drainage holes into the drainage pipe. The elastic sheet intercepts the garbage in the rainwater. When there is a large amount of garbage on the elastic sheet, the elastic sheet moves downward under the action of gravity, and the garbage is ejected, thereby avoiding the blockage of the drainage holes.

[0005] The applicant found that the above-mentioned pervious concrete structure has the following disadvantages in use: the strength of the pervious concrete structure is not high, and the rainwater is discharged through the drainage pipe, which requires the pervious concrete structure to be laid with a drainage pipe in advance, resulting in a long construction time and high cost.

[0010] The composite cement columns used for strength reinforcement of the plain soil ramming layer and the base broken stone layer are filled in the reinforcing holes arranged in the plain soil ramming layer and the base broken stone layer, the mineral admixture and the reinforcing agent are filled in the interior of the pervious plain color layer, and the reinforcing agent is filled in the gaps between the mineral admixtures for reinforcement treatment.

[0011] In a preferred embodiment, the thickness of the pervious concrete structure is greater than the plain soil ramming layer, the base broken stone layer and the pervious plain color layer.
