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 method for slope protection. The method includes the following steps that rivets are hit into a slope surface to lay and fix a slope surface iron gauge, then protection materials and grass seeds are uniformly mixed and formed through a stirring machine and by adding water, then the mixture is conveyed to a hydraulic spray-seeding machine through a pipeline to be sprayed to the slope surface, and the thickness of spraying is 7-10 mm; then watering maintaining is conducted on the spraying surface, and a sunscreen net or a thermal-insulation thin film is laid and disassembled after 20 days of maintaining. The limit value of compressive strength of a slope surface base material formed through the method is larger than or equal to 3.0 MPa, the slope surface base material and soil can interact with each other, the storing and transferring route for water, air, fertilizer, heat and other plant growth elements is provided, growth and development of plants are easy, conservation of water and soil of slope soil can be effectively improved, slope erosion can be prevented or slowed, and swelling falling, stripping, plant short-period degeneration and other phenomena can be avoided.

Description

technical field [0001] The invention relates to the field of slope management, in particular to a slope protection method. 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 ...
