Embodiment Construction

[0028] figure 1 The schematic flow chart of the anti-seepage method of the underground reservoir provided by the embodiment of the present invention, the present invention provides a kind of anti-seepage method of the underground reservoir, which includes the following steps:

[0029] Step a, laying anti-seepage concrete on the rock formation at the bottom of the reservoir. Among them, anti-seepage concrete refers to concrete added with anti-seepage materials such as chloride salt or triethanolamine.

[0030] In this step, the paving machine is used to lay the anti-seepage concrete, wherein the bottom rock formation of the underground reservoir can be analyzed, and the above-mentioned laying work can be done in the area where anti-seepage is required, instead of all areas at the bottom of the reservoir. The soil layer thickness of anti-seepage concrete paving is preferably 20-50cm, wherein 40cm is the best.

[0031] Step b, laying roller compacted concrete on the side wall o...

Abstract

The invention discloses a seepage-proofing method of an underwater reservoir and an underwater reservoir with a seepage-proofing function, wherein the method comprises the following steps: step a, paving impervious concrete on a rock stratum at the reservoir bottom; step b, paving roller compacted concrete on the side wall of the reservoir; step c, paving a first impermeable geomembrane on the roller compacted concrete; step d, paving normal concrete on the first impermeable geomembrane; step e, paving a second impermeable geomembrane on the top of the reservoir; and step f, paving smolmitza on the second impermeable geomembrane. By paving the impervious concrete on the bottom of the reservoir, paving the roller compacted concrete, the first impermeable geomembrane and the normal concrete on the side wall of the reservoir, and paving the second impermeable geomembrane and smolmitza on the top of the reservoir, the water seepage is effectively avoided, and the water quality is protected.

Description

technical field [0001] The invention relates to the construction technology of an underground reservoir for coal mining, in particular to an anti-seepage method for an underground reservoir and an underground reservoir with an anti-seepage function. Background technique [0002] In open-pit coal mining, storing groundwater resources, constructing underground reservoirs, and realizing future applications through pumping pipelines are of great significance for protecting water resources and realizing sustainable development of coal. [0003] However, in the existing underground reservoirs, due to the gaps between the rocks in the rock formations, water seepage will occur and water resources will be wasted. At the same time, external water will also infiltrate through the side wall of the reservoir and the top of the reservoir, affecting the water quality. Contents of the invention [0004] The invention provides an anti-seepage method of an underground reservoir and an unde...
