A Nursing Structure for Large Slope Stone Slopes Based on Inclined Planting Boards

Abstract

The invention provides a large-slope stone slope care structure based on inclined planting boards. Through the modular design of the nursing structure, the planting board and the frame can be assembled in advance. When installing on site, only the nursing structure module needs to be passed through The anchor fixing holes are fixed on the hillside, which can simplify the installation process and reduce the difficulty of installation; the planting board is designed as an inverted V shape, which can facilitate rainwater to slide from both ends of the planting board, and avoid overflow holes on both sides not being timely when there is too much rain. Drainage: overflow holes are opened at the closed ends of the two sub-boards to discharge excess rainwater out of the wedge-shaped grooves, and then collected by the water collection bags hanging on both sides; in the season of less rain, the control valve can be opened and the drip irrigation pipe Replenish water on slopes that need to be nursed to ensure the water needed for vegetation growth and reduce water transportation costs. The rainwater collection bag is made of flexible materials and can be accommodated between two adjacent nursing structure modules, saving space and increasing water storage capacity.

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
