Description
Technical field
With the utility model is related to the abundant flood of a kind of underground mine roadway grouting wall for grouting structure, especially water content
The wall body structure of lower mine working, belong to underground mine tunnel wall body structure technical field.
Background technology
In cranny development, aqueous abundant underground mine, tunnelling construction how waterproof, turn into engineering constraint build into
Degree and the most outstanding problem of investment.During this kind of underground mine roadway construction, use " has pick to visit, has doubtful ratio to control, first more
Dug after controlling " principle organizing construction, the detection of forward probe instrument or bore detecting are carried out before construction, it is found that front is present
After analysis of possibility of water inrush, then adopt an effective measure and carry out work of harnessing the river.
It is one of effective method for administering tunnel water burst to carry out crack grouting using the slip casting such as cement medium, ordinary circumstance
Under be to drilling of giving a farfetched interpretation in front of working face, high-pressure medium, effect of the medium in pressure are injected into drilling using high-pressure injection pump
Under, it can enter in rock fracture, after supersolidification, play a part of blocking crack and block water burst.
This method needs the intact rock of reserved certain distance, as the rock cap of slip casting, play stop highly pressurised liquid along
Working face sprays and causes the effect to fall flat.
In work progress, if after certain tunnel blasting terminates, crack of the water burst along working face sprays, such as still take with
Upper method carries out slip casting operation, then slip casting medium can spray under the effect of the pressure, cause material along the crack of working face
Waste, and the crack in front of working face because partial pressure by working face nearby discharge, do not reach reservation pressure, construction effect is not
It is preferable.Therefore, it is necessary to study a kind of measure, Artificial Rock cap can be used as, ensures that slip casting effect produces a desired effect.
Utility model content
The utility model purpose is to provide a kind of underground mine roadway grouting wall for grouting structure, after tunnelling water outlet,
It is close to rock cap of the tunnel work surface construction barricade as slip casting, ensures that slip casting is carried out in order, solve present in background technology
Problem.
The technical solution of the utility model is：
A kind of underground mine roadway grouting wall for grouting structure, includes concrete, valve, detection pipe, barricade, tapping pipe, height
Pressure ball valve and tunnel working face, the front of tunnel working face are provided with barricade, coagulation are provided between the barricade and tunnel working face
Soil, the bottom of barricade are provided with the tapping pipe of more parallel arrangements, and gear coping is provided with a detection pipe, the tapping pipe and inspection
One end of test tube is all extended in the working face of tunnel, and the other end of tapping pipe and detection pipe is located at outside barricade, the barricade of tapping pipe
Outer one end is provided with high-pressure ball valve, and one end outside the barricade of detection pipe is provided with valve.
The barricade includes the packed barricade of bottom and the top barricade on top, and the packed barricade of the bottom is by packed material
Material, which is built by laying bricks or stones, to be formed, and the top barricade on top is formed by brick masonry.
The packed barricade of the bottom is built by laying bricks or stones by bag of cement to be formed.
The tapping pipe is fixed on packed barricade.
It is packed in the men working of tunnel working face first after the working face crack water outlet of tunnel using the utility model
The aperture of barricade, and the pre-buried tapping pipe in packed barricade, the distance between packed barricade and tunnel working face and tapping pipe,
Quantity calculates according to grouting design.After the completion of packed Retaining wall, concrete is filled into the space of formation, treat with it is packed
When wall height is identical, stop filling.Brick masonry top barricade is used on packed barricade, is stopped apart from 10-20cm at the top of tunnel
Only, continue to fill concrete into the space of formation, until identical with top wall height.The top installation inspection of barricade on top
Test tube, then with concrete shotcrete machine, the injecting jet concrete into upper space, the filling concrete and tunnel for making bottom pushes up
Portion combine it is closely knit, after concrete curing is completed, reaches design strength, it is possible to which shutoff valve door seal blocks up water burst.
The beneficial effects of the utility model are：Avoid after tunnel working face crack water outlet is run into, Water outburst treatment difficulty,
The problem of long in time limit, costly.

Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1,2,3, a kind of underground mine roadway grouting wall for grouting structure, concrete, valve 2, detection pipe are included
3rd, barricade, tapping pipe 6, high-pressure ball valve 7 and tunnel working face 9, the front of tunnel working face 9 are provided with barricade, the barricade and lane
Concrete is provided between road working face 9, the bottom of barricade is provided with the tapping pipe 6 of more parallel arrangements, and gear coping is provided with one
One end of root detection pipe 3, the tapping pipe 6 and detection pipe 3 is all extended in tunnel working face 9, tapping pipe 6 and detection pipe 3
The other end is located at outside barricade, and one end outside the barricade of tapping pipe 6 is provided with high-pressure ball valve 7, and one end outside the barricade of detection pipe 3 is provided with
Valve 2.
In the present embodiment, in tunnelling work progress, as water burst occurs in tunnel working face 9 after explosion, then need
