Abstract
The utility model provides a big flood underground mine tunnel waterwall, belongs to mining technical field for administering the tunnel working face and gushing water, guarantee construction safety, its technical scheme is, including building near the twice manger plate enclosure the working face of tunnel, pre -buried aqueduct and the pre -buried pipe of a plurality of slip casting by laying bricks or stones during the waterwall constitutes, pre -buried aqueduct is located manger plate enclosure root and crosses twice manger plate enclosure, the pre -buried pipe of a plurality of slip castings cross twice manger plate enclosure and on the manger plate enclosure evenly distributed, all be equipped with the stop valve in the outer end of pre -buried aqueduct and the pre -buried pipe of slip casting, be equipped with between the twice manger plate enclosure and fill the concrete. The utility model discloses utilizing manger plate enclosure shutoff working face to gush water, adopting the working face method improvement tunnel yong shui of slip casting in advance again, not only can obtain the effect of harnessing the river of ideal, guarantee the safety of constructing, have construction convenience in addition, construction cost low grade characteristics can be widely used in big flood mine underground tunnelling.
Description
Technical field
This utility model relates to a kind of waterwall for administering flood underground mine tunnel retention of excessive fluid, belongs to mining technique field.
Background technology
In the tunneling process in underground mine tunnel, often there is crack retention of excessive fluid phenomenon in construction working face, affects construction safety and construction quality.Traditional Water outburst treatment measure is to use the method such as pre grouting from the surface, pre grouting from the working face closure crack, stops retention of excessive fluid to flow out.These methods are applicable to administer the tunnel water burst in face in general mine, but for flood underground mine, after tunnel blasting, retention of excessive fluid likely uninterruptedly can flow out along blasting crack or rock structure crack, when using traditional method to administer retention of excessive fluid, the liquid medium of injection can overflow along rock fracture, not only cause the waste of injecting paste material, and grouting quality cannot be ensured, thus have impact on the regulation effect of retention of excessive fluid.
Utility model content
The purpose of this utility model is the drawback for prior art, it is provided that a kind of flood underground mine tunnel waterwall, effectively to administer tunnel water burst in face, it is ensured that construction safety, improves construction quality.
Problem described in the utility model realizes with following technical proposals:
A kind of flood underground mine tunnel waterwall, composition includes building the twice coaming near the work surface of tunnel, pre-buried aqueduct and multiple slip casting built-in pipe by laying bricks or stones, described pre-buried aqueduct is positioned at coaming root and crosses twice coaming, multiple slip casting built-in pipes cross twice coaming and are uniformly distributed on coaming, it is equipped with stop valve in the outer end of pre-buried aqueduct and slip casting built-in pipe, between twice coaming, is provided with filling concrete.
Above-mentioned flood underground mine tunnel waterwall, also includes in composition checking built-in pipe, described inspection built-in pipe is positioned at the top in tunnel and crosses twice coaming, is provided with stop valve in the outer end checking built-in pipe.
Above-mentioned flood underground mine tunnel waterwall, the root of described coaming built by laying bricks or stones by bagged cement and forms, and remainder is brick wall.
Above-mentioned flood underground mine tunnel waterwall, described pre-buried aqueduct arranges multiple, and they are the most evenly distributed.
This utility model utilizes coaming to block water burst in face, the method using pre grouting from the working face again administers tunnel retention of excessive fluid, effect of preferably harnessing the river can not only be obtained, guarantee construction safety, and there is easy construction, the features such as construction cost is low, can be widely used in flood mine underground tunnelling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A sectional view.
Figure is respectively numbered: 1, check built-in pipe, 2, slip casting built-in pipe, 3, pre-buried aqueduct, 4, filling concrete, 5, brick wall, 6, bagged cement, 7, tunnel work surface.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, this utility model mainly includes checking built-in pipe 1, slip casting built-in pipe 2, pre-buried aqueduct 3, twice coaming and the filling concrete 4 being arranged between twice coaming, wherein, coaming by the bagged cement 6 built by laying bricks or stones in tunnel and is built the brick wall 5 on bagged cement 6 top by laying bricks or stones and is constituted.
In tunnel blasting work progress, if retention of excessive fluid occurs in work surface, hydrops in various degree near work surface, can be there is.Pile up twice cofferdam initially with the position that bagged cement 6 is selected near work surface, enough pre-buried aqueducts 3 are set in cofferdam simultaneously, enable the retention of excessive fluid of work surface by the pre-buried smooth and easy outflow of aqueduct 3.Use the Pumex between manually or mechanically equipment cleaning twice cofferdam again, after end for clearance, between twice cofferdam, pour prefabricated filling concrete 4.Fragment of brick is used upwards to build brick wall 5 by laying bricks or stones at top, cofferdam, as the template of follow-up filling concrete 4 construction.During building brick wall 5 by laying bricks or stones, installing slip casting built-in pipe 2 additional and check built-in pipe 1 in body of wall, the effect of slip casting built-in pipe 2 is to provide slip casting passage.Slip casting built-in pipe 2 both can be with advance reservation, it is possible to use down-the-hole drill boring to install after waterwall maintenance terminates.The effect of inspection built-in pipe 1 is after waterwall maintenance completes, and during closing pre-buried aqueduct 3, empties waterwall inner air, can detect when waterwall water level inside reaches top, tunnel simultaneously.After twice brick wall has been built by laying bricks or stones, continue to use space in filling concrete 4 filling cofferdam, until concrete and tunnel top contact.Closely knit with tunnel top contact in order to ensure concrete, can use the pulp shooting machine of roadway support that the whitewashing of gap, top is reinforced, the crack of down-the-hole grouting and reinforcing concrete and roadway surrounding rock can be used, it is ensured that the robustness of waterwall simultaneously.After having constructed and having reached curing period, it is possible to use conventional method to carry out Water prospect grouting work.
This utility model can effectively block water burst in face, during slip casting, can avoid rock fracture running pulp, it is ensured that grouting pressure reaches to design requirement, improves grouting quality.
