The invention discloses a construction waste water-permeable concrete production and preparation method. According to the method, construction waste with a particle size of 5-10 mm is selected for replacing natural stones to form a concrete framework; a part of cement is replaced by fly ash; an additive is added to improve performance of concrete; and an accurate calculation method of the usage amount of each component material is provided by utilizing the mass relationship among all the components and self parameters of all the materials. According to the method, construction waste with a single particle size is selected, and performance of the concrete can be regulated by controlling the particle size of the aggregate. The fly ash is used for partially replacing the cement, and the additive is added, so that performance of the concrete is greatly improved. The water-permeable concrete is prepared from the construction waste, so that recycling of solid waste is realized, environmentalprotection is facilitated, and engineering cost is reduced.
