Problems solved by technology

The effect of the above-mentioned patent applicant is very remarkable in the process of use, but the applicant found that due to the influence of the environment and geology, the slope of the slope in the karst area cannot store water well. Death due to lack of water, the current method is to use the spray gun of the high-pressure water truck to spray water on the slope. The method has the following problems. The water sprayed by the first high-pressure water gun is easy to wash away the solid soil layer formed on the slope; Second, artificial water spraying cannot achieve uniform watering; third, the cost of water transportation and high-pressure water spray vehicles is relatively high, and in seasons of water shortage, the amount of water volatilized by water spraying is relatively large, and the effective utilization rate is low; Four cannot be popularized on a large scale

Embodiment 1

[0018] Embodiment 1: As shown in Figure 1, the shrub slope protection area 1 that needs to be nursed is first cleaned and the pumice is removed, and then the drip irrigation device 6 is first laid on the shrub slope protection area 1. The drip pipe device 6 is composed of a grid of water pipes. The distance between its pipe and the pipe is about 1 meter, and the used water pipe 2 is a plastic pipe with an aperture of 2-3cm. A drip hole is opened on the water pipe 2. The aperture of the drip hole is 1-2mm, preferably 1mm; its water supply mode can be It is to connect the tap water nearby. In some areas without tap water, the water pump 5 can be used for direct water supply after the water is transported to the area by the tanker or a reservoir is built on the top of it, and the water in the tanker is sent into the reservoir for water supply. After completing the laying of the irrigation system, lay the water-retaining material 2 on the slope of the shrub slope protection area 1 ...

Embodiment 2

[0019] Example 2, such as figure 2 As shown, the shrub slope protection area 1 to be nursed is cleaned first, pumice is removed, and then the water-retaining material 2 is laid on the slope of the shrub slope protection area 1. The water-retaining material is sponge or rock wool, and then above the water-retaining material 2 Fix the geonet or the metal mesh 5 with anchor rods, set the planting device 3 that can stop the artificial soil and seeds from slipping on the geonet or the metal mesh 5, the planting device is a planting board or a planting lattice, a planting board or a planting lattice The structure has been introduced in the previous patents of the applicant; after the water-retaining material and the planting device are fixed, the spraying vehicle is used to spray artificial soil and plant seeds to the shrub slope protection area in the karst area where the planting device is fixed, and conventional care methods are adopted. Take regular care of it.

Abstract

The invention discloses a protection method for slopes in the karst regions and a structure thereof. According to the method, water retention materials are laid on the slopes of the shrub slope protection areas of the karst regions, a plant growing device capable of preventing artificial soil and seeds from sliding is arranged above the water retention materials, after the water retention materials and the plant growing device are fixed, a spray-seeding vehicle is adopted for spraying the artificial soil and the plant seeds to the shrub slope protection areas of the karst regions with the plant growing device fixed, and a conventional protection method can be adopted for carrying out timed protection on the artificial soil and the plant seeds. Due to the fact that the water retention materials are laid, the problem that water seepage is fast in the karst regions can be relieved to a large extent, sprouting and growing of plants can be guaranteed, and sprouting of the plants can be uniform.

Description

technical field [0001] The invention relates to a slope care method and structure in a karst area, which belongs to the slope protection construction technology of shrubs in a 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 rock and soil slopes that cannot recover vegetation. It is almost impossible to restore natural vegetation coverage on the surface in a short period of time. ; Existing slope engineering reinforcement measures mostly pursue strength and efficacy, and mostly adopt gray protection such as stone masonry and shotcrete, which destroys the harmony of natural ecology. ...
