Large-gradient rocky slope caring structure based on inclined vegetation plates

Abstract

The invention provides a large-gradient rocky slope caring structure based on inclined vegetation plates. By means of modular design of the caring structure, the vegetation plates can be assembled with a frame well in advance, a caring structure module only needs to be fixed to a hillside through anchors and fixing holes during on-site installation, and the installation process can be simplified and the installation difficulty can be reduced in this way. The vegetation plates are designed into inverted V shapes, rain can conveniently slide off the two ends of the vegetation plates, and the situation that rain cannot be discharged in time through overflow holes in the two sides when rain is too much is avoided. The overflow holes are formed in the sealed ends on the outer sides of two sub-plates, and too much rain is discharged out of wedge-shaped grooves to be collected by water collecting bags hung on the two sides. In the seasons with little rain, control valves can be opened to replenish water to a whole slope face needing care through drip irrigation pipes to ensure moisture required by growth of plants and reduce the water conveying cost. The rain collecting bags are made of flexible materials, can be stored between two adjacent caring structure modules, space is saved, and the water storage volume is also increased.

Description

technical field [0001] The invention relates to the construction technology of shrub slope protection in the karst (KST) area, in particular to a large-slope stone slope protection structure based on inclined planting boards. Background technique [0002] Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and the accompanying mechanical action. Karst landforms are widely distributed in Guangxi, Guizhou, Yunnan and other places in China. In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rocky slopes that cannot recover vegetation. It is almost impossible to restore vegetation coverage naturally on the surface in a short period of time; In some slope engineering reinforcement measures, the emphasis is on strength and efficiency, and most of them use gray protection such as stone masonry and shotcrete, which destro...

Problems solved by technology

In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rocky slopes that cannot recover vegetation. It is almost impossible to restore vegetation coverage naturally on the surface in a short period of time; Some slope engineering reinforcement measures mostly pursue strength and efficacy, and most of them use gray protection such as stone masonry and shotcrete, which destroys the harmony of natural ecology

With people's emphasis on ecological environment protection and the further increase of my country's economic strength, vegetation slope protection engineering technology has gradually been applied to engineering construction. Existing applications mostly use blasting afforestation methods, which are not suitable for karst landforms, or The slope is fixed by masonry and divided into small grids to make vegetation components, and then soil is planted in the divided grids to cultivate vegetation. Although such vegetation slope protection engineering technology has a certain greening effect, it still cannot meet the ecological requirements. Harmony and unity, man-made traces are too obvious

Most of the existing artificial slope greening and reconstruction projects are aimed at rocky slopes with a slope less than 75°. The planting components for slope protection of shrubs installed on the slopes in karst areas" and the "T-shaped planting boards for slope protection of slopes with shrubs installed on slopes in karst areas" can both achieve a good artificial soil attachment rate, which can be used after construction. Vegetation greening and regeneration will be completed within a few years; however, facing the complex and changeable characteristics of rocky slopes, rocky slopes larger than 75° or even 90° are often encountered during construction. There is no good solution yet. The common method is to re-clean the rocky slope to make the slope smaller. However, this method requires a large amount of construction, a long period of time, and is more dangerous
