Problems solved by technology

[0003] At present, there is no set of relatively complete systematic method, which can solve the problem of anti-seepage of various underground water-bearing rock and soil layers according to the geology, terrain and aquifer characteristics of underground ancient channels and ancient gullies, as well as the characteristics of aquifers and water supply conditions. , as well as the selection of the type of underground dam, the design of the dam height and the overflow section elevation of the dam crest, the recharge of the underground reservoir, and the improvement of the sustainability of the reservoir's water supply, etc.

Embodiment Construction

[0053] Out of the sense of responsibility and interest in the profession, the inventor began to study the construction of underground reservoirs for ancient rivers and gullies from the early 1980s. Characteristics and water supply conditions, anti-seepage methods for various underground water-bearing rock and soil layers, type selection of underground dams, design of dam height and dam crest overflow section elevation, and recharge and replenishment of underground reservoirs to improve reservoir performance. Continuity of water supply and other issues have been targeted research and experiments.

[0054] After many years of research and experimentation, from theory to specific technical difficulties such as engineering survey, design, construction, and methods for separating the water content of underground water-bearing rock and soil layers, a set of feasible methods has been created in an all-round way. At the same time, in the process of research and experimentation, I felt...

Abstract

The invention relates to a method for constructing an underground reservoir in an ancient gully of an ancient underground river channel. The method comprises the following steps: investigating the ancient gully of the ancient underground river channel, designing an underground reservoir dam body, designing an anti-seepage dam body in the reservoir area of the underground reservoir, carrying out stability assessment on the underground reservoir dam body, constructing the underground reservoir dam body, constructing the anti-seepage dam body in the reservoir area of the underground reservoir, surveying and mapping a longitudinal profile of the underground reservoir and calculating the volume of a water-bearing rock-soil layer of the underground reservoir, the water storage capacity of the underground reservoir and the average water separation quantity of an underground water-bearing layer; scientifically utilizing the water storage capacity of the underground reservoir and carrying out recharge and water replenishment on the underground reservoir. The method has the beneficial effect that aiming at the riverbed geology and the landform of the ancient gully of the ancient underground river channel, the characteristics of the water-bearing layer of the ancient gully of the ancient underground river channel as well as the supply conditions of a water source, the anti-seepage problem of various different water-bearing rock-soil layers and problems about the type selection of an underground water dam, the design of dam height and dam crest overflow section elevation, the recharge and the water replenishment of the underground reservoir and the improvement of water supply continuity of the reservoir can be systematically solved.

Description

technical field [0001] The invention is a method for constructing an underground reservoir by utilizing the special stratum, topography and groundwater conditions in the river bed of the ancient underground river channel and ancient gully to construct an underground dam to intercept and contain the diving in the underground aquifer, and belongs to the field of water conservancy construction. Background technique [0002] Since the 1980s, domestic and foreign media have made a lot of reports and comments on extreme natural disasters such as dust storms and droughts in my country. Some reports pointed out that the desertified area of ​​my country has accounted for one-third of the total land area. In my country, many provinces and cities absorb a large amount of groundwater due to drought and water shortage, causing the groundwater level to drop rapidly, causing ground cracks and subsidence, causing great economic losses and casualties to the country. As the contradiction betw...
