Problems solved by technology

[0003] However, underground reservoirs in coal mines are different concepts from underground reservoirs. Underground reservoirs in coal mines use man-made operations to use the mined-out areas of underground coal mines as water storage spaces and artificially build reservoir dams. The most important part of the construction process of underground reservoirs

Embodiment 1

[0039] Such as figure 1 As shown, an artificial dam body of an underground reservoir with a saw-toothed slot includes an artificial dam body construction area 1 and coal pillar dam bodies 2 located on both sides of the artificial dam body construction area 1, and the underground reservoir area 5 is a coal mining goaf The outside is roadway 3 and unmined coal seam 4 or rock formation; the key of underground reservoir is to seal the water inside the reservoir to prevent it from flowing out, so the sealing of artificial dam body is particularly important.

[0040] Such as figure 2 As shown, the uniform grouting elastic steel pipe 10 has a total length of 2.2m, an outer diameter of 0.08m, and a wall thickness of 0.02m. ), the outer area of ​​the coal pillar is composed of 8 (0.2m), the length ratio of the area with grouting holes inside the coal pillar to the area without grouting holes inside the coal pillar, and the outer area of ​​the coal pillar is 10:1:1, and the elastic st...

Embodiment 2

[0055] Such as figure 1 As shown, an artificial dam body of an underground reservoir with a saw-toothed slot includes an artificial dam body construction area 1 and coal pillar dam bodies 2 located on both sides of the artificial dam body construction area 1, and the underground reservoir area 5 is a coal mining goaf The outside is roadway 3 and unmined coal seam 4 or rock formation; the key of underground reservoir is to seal the water inside the reservoir to prevent it from flowing out, so the sealing of artificial dam body is particularly important.

[0056] The uniform grouting elastic steel pipe 10 has a total length of 2.3m, an outer diameter of 0.08m, and a wall thickness of 0.02m. The outer area of ​​the coal pillar is composed of 8 (0.19m), the length ratio of the area with grouting holes inside the coal pillar to the area without grouting holes inside the coal pillar, and the outer area of ​​the coal pillar is about 10:1:1, The material of the uniform grouting elast...

Embodiment 3

[0071] Such as figure 1 As shown, an artificial dam body of an underground reservoir with a saw-toothed slot includes an artificial dam body construction area 1 and coal pillar dam bodies 2 located on both sides of the artificial dam body construction area 1, and the underground reservoir area 5 is a coal mining goaf The outside is roadway 3 and unmined coal seam 4 or rock formation; the key of underground reservoir is to seal the water inside the reservoir to prevent it from flowing out, so the sealing of artificial dam body is particularly important.

[0072] The uniform grouting elastic steel pipe 10 has a total length of 2.4m, an outer diameter of 0.08m, and a wall thickness of 0.02m. The outer area 8 (0.2m) of the coal pillar is composed of the area with grouting holes inside the coal pillar and the area without grouting holes inside the coal pillar, and the length ratio of the outer area of ​​the coal pillar is about 10:1:1. The material of the uniform grouting elastic ...

Abstract

The invention provides an underground reservoir artificial dam body with zigzag clamping grooves, and relates to the field of groundwater resource protection. The underground reservoir artificial dambody comprises an artificial dam body and coal pillar dam bodies positioned on two sides of the artificial dam body, wherein the artificial dam body comprises an upper sealing sleeve piece and dam body modules, the upper sealing sleeve piece comprises uniform slip casting elastic steel tubes and slip casting drill holes, and the dam body modules comprise dam body modules with the zigzag clamping grooves and ordinary dam body modules; a plurality of uniform slip casting elastic steel tubes are arranged on the outer side of the coal pillar dam bodies; the other ends of the uniform slip casting elastic steel tubes are arranged inside the zigzag clamping grooves of the dam body modules with the zigzag clamping grooves; the uniform slip casting elastic steel tubes in the same vertical directionare communicated with the slip casting drill holes respectively; the tail ends of the slip casting drill holes extend to the outside of the coal pillar dam bodies; the dam body modules with the zigzag clamping grooves are fixedly connected through the ordinary dam bodies. The underground reservoir artificial dam body is constructed quickly, and the sealing performance of underground reservoir coal pillar upper and the artificial dam body is improved while the period and cost of reservoir construction are reduced.

Description

technical field [0001] The invention relates to the field of protection of underground water resources, in particular to an artificial dam body of an underground reservoir with saw-toothed slots. Background technique [0002] Corresponding to the surface reservoir, the underground reservoir is an ecological water conservancy project that uses natural underground water storage space to integrate water collection resource regulation, rain and flood resource utilization, and water ecological environment restoration. It is a water system management project with a harmonious natural environment. The underground reservoir strengthens the interconnection and transformation of surface water and groundwater, not only regulates surface water resources, but also regulates and stores groundwater resources, and realizes the joint utilization of surface water and groundwater. [0003] However, underground reservoirs in coal mines are different concepts from underground reservoirs. Undergr...
