Method for greening and restoring hard side slope

Abstract

The invention discloses a method for greening and restoring a hard side slope. The method comprises the steps of cleaning a slope surface, arranging an anchor rod, laying a galvanized wire mesh sheet,improving red sandstone into planting soil, laying a geomembrane, executing sowing, establishing an automatic irrigation system and executing operation and maintenance, wherein the red sandstone soillayers with different sandstone contents are improved by adding an improver, meanwhile spray heads are installed on a pre-buried spray system by utilizing an automatic control system, and planted plants are irrigated by using the spray heads. A sprinkling irrigation system can be automatically controlled according to temperature and humidity. The invention provides a hard slope greening restoration technology for improving red sandstone into planting soil. Long-term growth conditions are provided for vegetations, the ecological restoration requirements of a rock slope and a hard slope are met, slope protection greening planting plants are combined with a traditional vegetation concrete ecological-restoration technology, vegetation restoration and anchoring fixation are simultaneously carried out, and the vegetation growth on slopes and slope fixation can be better achieved.

Description

technical field [0001] The invention relates to the fields of ecological restoration engineering and greening engineering, in particular to a method for greening and repairing hard slopes. Background technique [0002] Due to the acceleration of urban construction in my country in recent years, the destruction of vegetation is more serious, resulting in a significant reduction in green area, which in turn has aroused people's attention to the environment and ecological balance. The new ecological slope protection has begun to be widely used. In hydropower, transportation, municipal and mining projects, due to construction excavation, a large number of exposed rock slopes are formed. Some slopes are protected by shotcrete, masonry and other projects to form hard slopes. These rocky slopes, Due to the lack of vegetation growth conditions and poor ecological environment on hard slopes, the demand for slope landscape effects has not been well resolved for a long time.

AI Technical Summary

Problems solved by technology

After excavation or blasting, most red sandstones can be disintegrated and broken by the atmospheric environment, or even muddy. Therefore, the size and particle gradation of the rock blocks will change with the time course of the dry-wet cycle, and their physical and mechanical properties will also change. There will be changes. In the existing technology, the original red sandstone cannot be used for the green restoration of the hard slope, and the planting soil needs to be re-laid, which is too expensive.
