Vegetation member for protecting karst region slope and protecting method using member

Abstract

The invention discloses a vegetation member for protecting a karst region slope and a protecting method using the member. The vegetation member (1) is fixed on the karst region slope, and the vegetation member (1) is formed by mutually connecting one or more than one hollow column (2). The vegetation member is made into a mesh shape, the meshes are formed by mutually connecting a plurality of hollow columns, and when artificial soil is sprayed and seeds are sowed, the artificial soil and the seeds can be deposited on and in the hollow columns, so a good attachment platform surface is provided for the artificial soil and the seeds, expansion of roots when the plant is grown is better ensured and a foundation is laid for the growth of vegetation.

Description

technical field [0001] The invention relates to a vegetation component for slope surface protection in a karst area and a protection method for the component, belonging to the shrub slope protection construction technology in the karst (KST) area. 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 s...

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

On May 8, 2009, the applicant applied for two patents, Nos. 2009203029557 and 2009203029595, respectively named "a shrub slope protection planting component arranged on the slope of the karst area" and "a planting component installed on the slope of the karst area". The patent of T-shaped planting board for shrub slope protection on the slope above has been obtained. The above two patents have been used so far and the effect is relatively satisfactory. However, the applicant found that the planting board has troubles in fixing, low efficiency, and Fixing is not firm enough. If the planting board collapses, the artificial soil stacked on the planting board will fall off, and it will be difficult to grow vegetation in places without artificial soil; therefore, the existing planting components have high costs and hanging nets Difficult and slow problems cannot well meet the rhythm and trend of modern high-speed and high-efficiency
