Method for protecting vegetation of concrete slope

Abstract

The invention discloses a method for protecting vegetation of a concrete slope, which comprises the steps of: a, removing a cement paste hardening layer by an excavator or forming vegetation holes on the cement paste hardening layer; b, arranging a vegetation plate and spreading a fixing net on the slope surface which is processed by the step a, or arranging vegetation grids and spreading a fixing net on the slope surface which is processed by the step a; c, spraying a nutritive substance onto the slope surface which is paved with the vegetation plate and the fixing net by a mechanical or a manual operation until the thickness of the nutritive substance is 5-8cm; d, spraying a plant growth substance which is mixed with seeds onto the upper side of the nutritive substance by a spraying machinery until the thickness of the plant growth substance which is mixed with the seeds is 2-3cm. According to the method, the test shows that the effect that the vegetation recovery is performed on the slope surface with the concrete is extremely ideal; and the nutrition is completely guaranteed to be stably attached to the slope surface while the nutrition substance is sufficiently provided.

Description

technical field [0001] The invention relates to a protection technology, in particular to a method for planting vegetation on a concrete slope. Background technique [0002] In the treatment of slopes, shotcrete is a more traditional method. Although it can effectively prevent the occurrence of secondary disasters such as landslides and debris flows within a certain period of time, it often leaves a piece of concrete itself that is gray and visually impaired. The image is very poor, and it is out of tune with the surrounding vegetation environment, which is extremely incongruous. With the development of society and people's attention to the ecological environment, the traditional governance has been unable to meet the needs of modern times, and a new type of governance has emerged - ecological governance. The restoration of vegetation has been achieved by means of methods, and certain effects and progress have been achieved. For example, the Chinese patent No. 200510032542....

AI Technical Summary

Problems solved by technology

Concrete has high strength, good integrity, compact structure, smooth slope, and inaccessible plant roots, which also makes it more difficult to restore vegetation on concrete slopes.

After hard work, the "high-order group" spraying substrate, porous ecological concrete mechanism, ecological pad, etc. can also be suitable for the growth of slope vegetation sprayed with concrete, but these technologies have disadvantages, such as the thickness of the plant growth substrate cannot be guaranteed, and nutrients cannot be continuously replenished The key issues of vegetation restoration on concrete slopes, such as easy compaction of the soil layer, inability of vegetation to grow for a long time, and high maintenance and management costs in the later stage, have not been implemented.
