Problems solved by technology

At present, adding additives is generally used to improve the compressive strength of vegetation-type permeable slope protection materials, and the alkali content inside the concrete is reduced by adding silica powder, fly ash or spraying ferrous sulfate solution, but there are still insufficient strength or poor water permeability, sulfuric acid, etc. Problems such as low utilization efficiency of ferrous solution
In addition, the research on vegetation-type permeable slope protection materials mainly focuses on water permeability, mechanical strength, and reducing the alkali content inside concrete. and groundwater pollution are less studied

Abstract

The invention relates to a self-purifying planting type water-permeable slope protection material and a preparation method thereof. The self-purifying planting type water-permeable slope protection material comprises a self-purifying planting type water-permeable concrete base layer and a photocatalyst coating, wherein the self-purifying planting type water-permeable concrete base layer comprisessilicate-titanium salt slurry, cement strengthener and an active porous material; and the photocatalyst coating is sprayed on the self-purifying water-permeable concrete base layer, and the amount ofthe photocatalyst coating is 2.0 to 7.0 L / m<2>. The self-purifying planting water-permeable slope protection material can degrade organic pollutants in river water or reduce the heavy metal entering the underground water by permeating into the soil, and is high in strength and suitable for the growth of plants.

Description

technical field [0001] The invention belongs to the technical field of civil engineering materials, and in particular relates to a self-purifying vegetation type permeable slope protection material and a preparation method thereof. Background technique [0002] For a long time, various hard slope protection methods have been widely used due to the excessive emphasis on the resistance of river embankments to water flow, wind and wave invasion and erosion. While meeting the functional requirements of slope protection, this type of slope protection method isolates the material exchange between soil and water, destroys the original ecosystem in the river bank area, causes a decline in biodiversity, leads to the loss of ecological functions of slope protection, and the self-purification function of water bodies decline or even complete loss. [0003] With the development of social economy and the improvement of living standards, and the enhancement of human awareness of environm...
