The invention discloses a water-purifying greening brick applied to ecological slope protection, comprising soil-covered hollow blocks, composite drainage nets and permeable porous blocks arranged in sequence from top to bottom; the soil-covered hollow blocks are made of dredged mud. , zeolite, fly ash, Portland cement, water glass, lignosulfonate, water, the permeable porous block is composed of ceramic particles, clay, external admixture, Portland cement, pore former, hydroxypropyl methyl cellulose and water; the invention also discloses a preparation method of the water-purifying green brick. The soil-clad hollow block of the present invention is lightweight, has strong structural stability, and the water-permeable porous block has good water permeability and high porosity. The block combination can not only effectively protect the ecological slope, but also realize the absorption, anti-filtration, purification, drainage and protection of rainwater. |
