Ecological green plant component for steep slope reinforcing repair and preparation method

The invention discloses an ecological green plant component for steep slope reinforcing repair and a preparation method. The preparation method comprises the steps of 1, carrying out screening, cutting, fine grinding and water flushing on constructional engineering waste with metal and wood removed to obtain particles with the particle size of 0.5mum-4mum, and drying the particles; 2, evenly mixing and stirring rapid-hardening sulphate aluminum cement, fly ash, humus soil, the particles obtained in the step 1 and carbon black to obtain A; then evenly mixing animal bone glue powder, a water reducing agent, polyving alcohol, cellulose ether, polypropylene fibers and sodium bicarbonate to obtain B; 3, evenly mixing the B and the A, adding water, pouring the mixture into a component mould, and preparing the ecological green plant component for steep slope reinforcing repair. The ecological green plant component for steep slope reinforcing repair is friendly to the environment and suitable for plant growing, has the water-retaining property, fertilizer-retaining capacity, water permeability and breathability, and can provide the largest growing space for plants and a nutrition medium required by growth.
