Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0033] like figure 1 Shown is a schematic structural view of an embodiment of the karst funnel reservoir of the present invention. The karst funnel reservoir of this embodiment includes a double-layer shell sealing structure 2 for blocking the water leakage channel of the karst funnel, which is used for forming between the double-layer shell sealing structure 2 and the surrounding rock mass 1 of the karst funnel located on its upper part. In the water storage area 3 where the water is stored and treated with anti-seepage. In the water storage area, there are flood discharge buildings for flood discharge, water intake buildings for water intake, and emptying buildings for emptying...

Abstract

The invention discloses a double-layer-shell blocking structure. The double-layer-shell blocking structure comprises a base which is arranged around the inner wall of the water leakage channel of the karst-funnel reservoir for a circle; a double-shell structure used for blocking the water leakage channel of the karst-funnel reservoir is arranged in the base; and the double-layer-shell structure comprises an upper-layer blocking shell and a lower-layer blocking shell which is located below the upper-layer blocking shell. The invention further discloses a karst-funnel reservoir and a construction method of the double-layer-shell blocking structure. According to the double-layer-shell blocking structure, the double-layer-shell structure is arranged in the base, so that the self-weight of reserved water and silt and other load are converted into pressure and transmitted to surrounding rock mass, and thus pulling force borne by the blocking structure can be effectively reduced; and therefore construction load is reduced, and economy is good.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, in particular to a karst funnel reservoir and its double shell sealing structure and construction method. Background technique [0002] my country's karst landforms are widely distributed and large in area, mainly in areas where carbonate rocks are exposed, with an area of ​​about 910,000 to 1,300,000 square kilometers. Among them, Guangxi, Guizhou and eastern Yunnan occupy the largest area and are one of the largest karst landform areas in the world. The main karst landform areas in my country are also areas rich in atmospheric precipitation. However, due to poor surface water storage conditions, most of the precipitation enters the underground karst system through karst funnels, which makes the surface water resources in karst landform areas not rich. There is even a prominent seasonal water shortage problem, which seriously affects the local economic and social developmen...
