Protecting structure for big-gradient stone slope

Abstract

The invention provides a protecting structure for a big-gradient stone slope. According to the protecting structure, plant-growing plates are designed into inverse V-shapes, so that rainwater can fall from two ends of each plant-growing plate conveniently, and thus the condition that plants are soaked by rainwater since water cannot be discharged from overflow holes in two sides in time when rainwater is excessive is avoided. Overflow holes are formed in the sealed ends of the outer sides of two sub-boards and used for draining excessive rainwater from wedge-shaped grooves; since the overflow holes are formed in the middle and can be used for conserving certain rainwater, and self-irrigation can be carried out through cotton slivers. Since each plant-growing component is of a trapezoid platform structure, the plant-growing plates and frames form wedge-shaped grooves, and after each plant-growing component is clamped into the corresponding wedge-shaped groove, a small wedge-shaped space is also reserved at the lower part of the corresponding plant-growing component, so that the rainwater can be stored in the space; in less rainfall seasons, since the cotton slivers are tied on water falling holes in the lower end of each grow-planting component, the rainwater stored in the lower end can be replenished to roots to plants according to a capillary principle.

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°. 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
