A Nursing Structure for Large Slope Stone Slopes

Abstract

The invention provides a nursing structure for large-slope stone slopes. The planting board is designed as an inverted V shape, which can facilitate rainwater to slide down from both ends of the planting board, and prevent the overflow holes on both sides from being unable to drain water in time when there is too much rainwater. Cause rainwater to soak vegetation. An overflow hole is opened at the closed end of the outer side of the two sub-boards to drain excess rainwater out of the wedge-shaped groove, and there are water collecting bags hanging on both sides for collection. Because the overflow hole is opened in the middle, a certain amount of rainwater can also be preserved, and the water supply of vegetation can be kept for a certain period of time. In the less rainy season, the control valve can be opened to replenish water to the entire slope that needs to be nursed by the drip irrigation pipe, so as to ensure the water needed for vegetation growth and reduce the cost of water transportation. 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 nursing structure for large slope stone slopes. 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 destroys the harmony of natural ecolog...

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°. A kind of shrub slope protection planting component set on the slope in karst area" and "T-shaped planting board for slope protection slope shrub set on the karst area slope" can both achieve a good artificial soil attachment rate, and can be installed after construction Vegetation greening and regeneration can be completed within a few years; however, in the face of complex and changeable characteristics of rocky slopes, rocky slopes larger than 75° or even 90° are often encountered during construction. At present, there is no good solution. The common method is to re-clean the stone slope to make the slope smaller. However, this method requires a large amount of construction, a long period of time, and is more dangerous.
