Embodiment 1

[0028] Such as figure 1 As shown, in this embodiment, the new ecological permeable concrete pavement includes a permeable surface layer, a permeable structure layer, a recycled aggregate base layer and a rammed soil base layer arranged in sequence. Among them, the permeable surface layer is cement permeable mortar (or colored permeable finish) with a weight ratio of cement and sand of 1:4 and a thickness of 30mm; the permeable structure layer is 150mm and a compressive strength of 21.5Mpa. Granular permeable concrete; the thickness of the base layer of recycled aggregate is 100 mm, which is the aggregate with a particle size of 5 mm after crushing, screening, and impurity removal processes for concrete construction waste; the base layer is plain soil rammed soil foundation.

Abstract

The invention discloses a novel ecological water permeation concrete pavement. The novel ecological water permeation concrete pavement comprises a water permeation surface layer, a water permeation structural layer, a renewable aggregate base layer and a compacted soil substrate layer which are successively arranged; the water permeation structural layer is made of coal ash ceramicite water permeation concrete; and the renewable aggregate base layer is made of concrete-type construction garbage renewable aggregates. By adopting the novel ecological water permeation concrete pavement, the problem of the pollution of the coal ash waste is solved, the concrete-type construction garbage is sufficiently utilized, waste is converted into treasure, and the environmental protection is facilitated; and the water permeability and the water storage property are good, the strength is high, and the comprehensive utilization of the sponge urban construction for solid wastes and construction garbage is realized.

Description

technical field [0001] The invention belongs to the technical field of pavement, and in particular relates to a novel ecological permeable concrete pavement. Background technique [0002] Fly ash, commonly known as fly ash, is the main solid waste discharged from coal-fired power plants, and it is also one of the largest industrial wastes in my country. In recent years, with the increase in demand for resources, the output of fly ash has been increasing year by year. According to related reports, in 2015, my country's fly ash output exceeded 600 million tons, ranking first in the world. The gray forecast model estimates that China's fly ash emissions will reach 900 million tons by 2020. If the fly ash is not treated, it will generate dust and pollute the atmosphere. If it is discharged into the water system, the river will be silted up, and the toxic chemicals in it will also cause harm to the human body. Therefore, how to rationally utilize fly ash and realize the reuse o...
