Embodiment Construction

[0037] 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.

[0038] 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-curved arched beam-slab sealing structure 2 for sealing off the leakage channel of the karst funnel, and the double-curved arched beam-slab sealing structure 2 and the surrounding rock of the karst funnel located on its upper part A water storage area 3 for storing water and treated with anti-leakage is formed between the bodies 1 . In the water storage area, there are flood discharge buildings for flood discharge, water intake buildings for water intake, and emptying buildings for emptyi...

Abstract

The invention discloses a double-curved-arch-shaped beam plate plugging structure comprising a concrete base arranged in a mode of embracing by one circle along the inner wall of a water leakage channel of a karst funnel. Concrete plates used for plugging the water leakage channel of the karst funnel are arranged in the concrete base; concrete beams used for supporting the concrete plates are arranged under the concrete plates and comprise the cross beams and the longitudinal beams; the two ends of the cross beams and the longitudinal beams are both arranged on the concrete base; and in the vertically-downward view direction, the cross beams and the longitudinal beams are orthogonal mutually, the elevations of the top faces at the intersections of the cross beams and the longitudinal beams are equal, and a double-curved-arch-shaped face grid structure used for supporting the concrete plates is formed on the top faces of the cross beams and the longitudinal beams. The invention further discloses a karst funnel reservoir and a construction method of the double-curved-arch-shaped beam plate plugging structure. According to the karst funnel reservoir and the double-curved-arch-shaped beam plate plugging structure thereof and the construction method, the requirement for plugging the concentrated water leakage channel of the karst funnel can be met.

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-curved arch beam-slab sealing structure and construction method. Background technique [0002] my country's karst landforms have a wide distribution and a large area, mainly in areas where carbonate rocks are exposed, covering 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 ...
