Recycled aggregate ecological concrete slope protection structure based on capillary retardation and construction method

The invention provides a recycled aggregate ecological concrete slope protection structure based on capillary retardation and a construction method, and the slope protection structure comprises a slope soil body, and an impermeable layer, a recycled aggregate ecological concrete layer, a root growth layer, a plant-growing concrete layer and a planting soil layer which are sequentially laid on an original soil surface layer of the slope soil body from bottom to top, the recycled aggregate ecological concrete layer comprises recycled aggregate ecological concrete and nutritional geotechnical cloth laid on the recycled aggregate ecological concrete, communicated macropores are formed in the recycled aggregate ecological concrete layer and the vegetation type concrete layer, and the PH value of the vegetation type concrete layer is 8-10. According to the structure, the slope body is communicated with the atmospheric environment through reasonable matching of the structures of all the layers, a good living space i
