Embodiment 1

[0025] Embodiment 1: A method for water and soil resources conservation in karst areas. Several reservoirs 2 are distributed on mountains 1 in karst regions. The number of reservoirs 2 depends on the elevation and slope of the mountains. The adjacent upper and lower reservoirs 2 are connected to each other, and the connection method depends on the actual situation. For example, the upper and lower reservoirs can be connected by a single line, see figure 1 , the upper and lower reservoirs can also be used to form a network connected structure, see Figure 6 .

[0026] A return channel 7 for collecting muddy water is arranged on the slope protection, and the muddy water gathers in the nearby water storage 2 along the return channel 7, so as not to be washed directly under the slope protection. The purpose of setting the reservoir 2 is exactly to be able to reclaim the muddy water for reuse.

Embodiment 2

[0031] Embodiment 2: a kind of distributed steel plate storage reservoir, such as figure 1 or Figure 6 , a plurality of steel plate storage reservoirs are distributed on the mountain body 1 in the karst area, and each layer of steel plate storage reservoirs includes a water inlet 22 and a water outlet 23, and the water outlet of the upper layer of steel plate storage reservoirs communicates with the water inlet of the lower layer of steel plate storage reservoirs A valve is set on the pipeline 3; a dredging channel and a sealing door 21 are set at the bottom of each steel plate storage reservoir; a return channel communicating with the steel plate storage reservoir is set on the mountain 1 in the karst area. To prevent sediment from being discharged, a filter layer 24 is provided on the side or bottom inside the steel plate storage reservoir to form a filter chamber, and the water outlet 23 is located on the side wall of the filter chamber. Water pump 25 is installed in filt...

Abstract

The invention discloses a water and soil resource keeping method and a distributed steel storage reservoir in a karst region. Multiple steel storage reservoirs are distributed on a karst mountain, a water outlet of an upper steel storage reservoir is communicated with a water inlet of a lower steel storage reservoir through a pipeline, and a valve is arranged on the pipeline; a dredging channel and a sealing door are formed and arranged at the bottom of each steel storage reservoir; a backflow channel which is communicated with the steel storage reservoirs is formed in the karst mountain. By using the water and soil resource keeping method, the purpose of collecting layered muddy water in the karst region can be realized, and silt can be laid on slope protection again, so as to achieve the purpose of keeping water and soil without loss. Water resources are stored, combined dispatching and optimal management of the water resources can be performed in the karst region, the problem of engineering water shortage is solved, and appropriate local planting management is combined, so that an obvious effect is achieved.

Description

technical field [0001] The invention relates to the technical field of protection of water and soil resources in karst areas, in particular to a water storage reservoir for joint dispatching of interconnected water constructed by distributing several steel silos according to the landform conditions of karst mountainous areas. Background technique [0002] Karst (karst) is widely distributed in my country, accounting for more than 1 / 3 of the country's land area. Among them, the exposed area of ​​karst is 910,000 square kilometers, mainly distributed in the eight southern provinces mainly in Yunnan, Guizhou and Guangxi. Geographical units with special features. [0003] The karst area in southern China, centered on the Guizhou Plateau, is the world's largest, most complex, and most concentrated ecologically fragile area. The terrain of this area is high in the west and low in the east, with an average altitude of about 1100 meters. With an area of ​​more than 550,000 square ki...
