Problems solved by technology

Chinese patent CN1358685 discloses a greening concrete additive, which belongs to the additive component of the concrete used for slope greening, and solves the problem of vegetation growing in the concrete during the slope greening process
Relevant reports mainly focus on the compounding of plant seeds and growth substrates, and there are few studies on the modification of slope soil, resulting in the phenomenon of wet swelling, falling, peeling, and short-term vegetation degradation after ecological protection treatment.

Abstract

The invention discloses a side slope protective material, which comprises following raw materials in parts by weight: 50 to 60 parts of common silicate cement, 30 to 40 parts of clay, 5 to 15 parts ofcotton seed hull, 5 to 10 parts of yellow sand, 5 to 15 parts of corn straw, 1 to 10 parts of ceramsite, 1 to 10 parts of pumice stone, 1 to 10 parts of polyphenyl particle, 4 to 8 parts of active carbon powder, 5 to 10 parts of nano iron, and 6 to 12 parts of modified Chinese medicine residue. The protective material can interact with soil, provides a storage and migration channel for growth factors for plants such as gas, water, fertilizer, heat, and the like; is beneficial for the growth of plants, can maintain the water and soil of side slops, prevents side slopes from being corroded, andavoids the phenomenon such as swelling of side slopes, stripping, short-term vegetation degradation, and the like.

Description

technical field [0001] The invention relates to the field of slope treatment, in particular to a slope protection material. Background technique [0002] Slope ecological protection technology is based on the basic principles of ecological engineering, engineering mechanics, botany, hydraulics and other disciplines. It uses active vegetation materials and other engineering materials to build an ecologically functional slope protection system on the slope. Support, self-organization, and self-repair functions to achieve anti-erosion, anti-sliding and ecological restoration of slopes, so as to reduce soil erosion, maintain ecological diversity and ecological balance, and beautify the environment. In recent years, my country's slope ecological protection technology has been developed to a certain extent. It can make up for the shortcomings of traditional protection engineering slope protection, and can meet people's requirements for environmental protection. However, due to its...
