Problems solved by technology

There are often potholes of different sizes on this kind of slope, which is not convenient for hanging nets. If it is not filled and leveled, it will waste a lot of substrates and increase construction costs.
And the substrate is sprayed too thick, which is not conducive to water and soil protection, and the slope protection ability is poor

Abstract

The invention relates to an ecological protection structure suitable for a bumpy rock slope and a construction method. The ecological protection structure comprises cement soil sprayed on a slope surface, an iron gauze laid on a cement soil layer, a short anchor rod for fixing the iron gauze and a base material spraying layer; the base material spraying layer is located on the cement soil layer; and the base material spraying layer comprises a base layer containing no mixed plant green seeds and a surface layer containing mixed plant green seeds. Base materials of three technologies are adopted, cement soil layer and vegetation concrete spraying construction can be completed through a dry type concrete spraying machine or a soil dressing spray-seedling machine or a wet type spraying machine according to the different base materials, the construction process is simple, the construction period is short, the construction cost is low, the method is suitable for slope protection and ecological restoration of uneven rock slopes, and wide application prospects are realized.

Description

technical field [0001] The invention relates to an ecological protection technology for potholes and uneven rock slopes, and belongs to the field of ecological slope protection. Background technique [0002] Limestone slopes are prone to potholes and uneven slopes. Limestone is not hard and easy to dissolve. Its unevenness is formed by geological action. This kind of slope often has potholes of different sizes, which is not convenient for hanging nets. If the construction is sprayed without filling, it will waste a lot of substrates and increase the construction cost. And the substrate is sprayed too thickly, which is not conducive to soil and water protection, and the slope protection ability is poor. In order to simplify construction, reduce costs, and improve slope stability, new ecological protection structures and methods need to be proposed. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose an ecological protection structure and a...
