Description
Technical field
The present invention relates to protection of groundwater resource fields, and in particular to a kind of groundwater reservoir artificial dam with zigzag card slot
Body.
Background technique
Groundwater reservoir is corresponding with Surface reservoir, is collection Water Resource Adjustment And Control, the rain built using natural groundwater storage space
The big vast utilization of resources and water ecological environment reparation are that the water system of natural environment syntonic type is ruled in the ecological hydro-junction engineering of one
Science and engineering journey.Groundwater reservoir enhances connecting each other and converting for surface and ground water, both has adjusted surface water resources, also regulates and stores
Groundwater resources, the joint for realizing surface water and groundwater utilize.
But coal mine underground reservoir and groundwater reservoir are different concept again, and coal mine underground reservoir is to utilize artificial work
Industry manually builds reservoir dam using the goaf of downhole coal mine as water holding space, in the building course of entire groundwater reservoir most
Important and maximal workload thing is exactly the build of artificial dam body；Current artificial dam body main material is brick, sandstone and
Cobblestone etc., main technique are to build in layer；This technique construction-time is too long, it is also necessary to arrive equipment and manpower movement
Next dam body build area greatly improves the construction and draining cost of reservoir；
Therefore accelerate construction speed, improve and build intensity and sealing performance, ensure that reservoir safety is urgently to be solved at present
Problem.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of artificial dam body of the groundwater reservoir with zigzag card slot,
The artificial dam body of groundwater reservoir is quickly built, while reducing the period for building reservoir and cost, improves portion, groundwater reservoir coal column side
With the leakproofness of artificial dam body.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of artificial dam body of the groundwater reservoir with zigzag card slot, including artificial dam body and be located at the artificial dam body two sides
Coal column dam body, the artificial dam body include side portion's Seal Kit and dam body module, and the portion, side Seal Kit includes uniform slip casting
Elastic steel pipe and inlet well, the dam body module include the dam body module with zigzag card slot and common dam body module, described
The outside of coal column dam body is equipped with several uniform slip casting elasticity steel pipes, and one end of the uniform slip casting elasticity steel pipe is arranged described
At 60 ° of acute angles in coal column dam body and with the trend in tunnel, the other end of the uniform slip casting elasticity steel pipe is arranged in the band saw
In the zigzag card slot of the dam body module of dentation card slot, the uniform slip casting elasticity steel pipe of same vertical direction with the note
Slurry drilling communicates, and the end of inlet well extends to outside the coal column dam body, between the dam body module with zigzag card slot
It is fixedly connected by common dam body module.
Preferably, the length of the uniform slip casting elasticity steel pipe is 2.2-2.5m, overall diameter 0.08m, and wall thickness is
0.02m has note inside the coal column by being formed by inside slip casting porose area, coal column without slip casting porose area, coal column outside area inside coal column
Starching the length ratio without slip casting porose area, the coal column outside area inside porose area and the coal column is 10:1:1, the uniform slip casting bullet
Property steel pipe material be high strength steel, there is inside the coal column slip casting porose area to be equipped with injected hole, the slip casting bore dia
0.0040-0.0048m, array pitch 0.10-0.18m, spacing 0.020-0.28m.
Preferably, the diameter of the inlet well is 0.10-0.18m.

The above-mentioned artificial dam body of the groundwater reservoir with zigzag card slot, construction technology the following steps are included:
(1) expand side: rejecting some broken loose coal petrographys in portion, coal column dam body side surface, expand the length of side by following
Two conditions:
1. length is greater than 0.4m
2. guaranteeing last two, to help intermediate distance be 1+0.3t, and t is integer, and t is the dam body mould with zigzag card slot
The number of rows of block；
(2) in coal column dam body side portion's drilling, the uniform slip casting elasticity steel pipe, the uniform slip casting elasticity are installed
30 ° of steel pipe and coal column surface angle, are referred to as layer in short transverse, layer is array pitch on front-rear direction, arranges away from being 0.60-0.64m
Away from for 0.50-0.55m；
(3) inlet well, the inlet well end and coal column dam body inside are beaten on the coal column dam body
Distance is the 20% of coal column dam body width, if coal column dam body width is lower than 5m, the inlet well end and the coal column dam
