Method for rapidly realizing re-greening of red sandstone slope

Abstract

The application provides a method for rapidly realizing re-greening of a red sandstone slope. The method comprises steps of slope cleaning, excavation of planting holes, base material filling in planting holes, spaced sowing of bushes, grass seed spraying, non-woven fabric covering and maintenance management. Planting holes are dug in the surface of a red sandstone slope and thus water storage containers are installed at the slope surface similarly, so that moisture and nutrients that are need for long-time plant growing are kept in the base material and thus a problem of the poor water retention effect of the weathering or semi-weathering red sandstone slope is solved. The base material is a plant cultivation base material that is produced based on a scientific proportion after fermentation of agricultural and forestry wastes and contains lots of beneficial microorganisms; and since the base material contains lots of humic acid and beneficial microorganisms capable of realizing soil degradation, the speed of weathering of the red sandstone into soil is increased and minerals and nutrients absorbed by the roots of the plants are released, so that problems that the red sandstone soil is impoverished, the weathering speed is fast, and the own minerals can not be absorbed by the plant and the like are solved.

Description

technical field

[0001] The application relates to the technical field of slope protection, in particular to a method for rapid regreening of red sandstone slopes. Background technique

[0002] With the construction of the expressway, a large number of slopes have been generated during the construction process, which not only destroys the natural environment, but also causes serious soil erosion. The environmental protection department requires that the safety and stability of the slope surface should be ensured during the slope protection process. , but also pay attention to ecological restoration. Among them, the slopes include red sandstone slopes, which are red, dark red or brown due to rich oxides. Affected by the geological structure characteristics of red sandstone, red sandstone slopes are prone to accidents such as landslides, so it is urgent to take protective measures for red sandstone slopes.

[0003] The geological structure of red sandstone is divided into Cla...

Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0042] Weathered or semi-weathered red sandstone slopes often have the characteristics of easy weathering and fracture of the surface layer, fast heat absorption, large water evaporation and poor water retention. In addition, such red sandstone slopes have poor soil and fast weathering speed. The material content is high, but it is difficult ...
