Abstract
The utility model relates to a drainage ditch for coal mine. The drainage ditch comprises a temporary ditch dug at a roadway base plate of the coal mine, wherein the drainage ditch also comprises an impermeable belt paved inside the temporary ditch; the middle part of the impermeable belt is lower relative to the two sides along the extending direction of the temporary ditch. When the temporary ditch is stressed and deformed, floating recrement and floating coal in the temporary ditch are shoveled, then the impermeable belt is paved, and the impermeable belt does not need to be repaired, so that both time and labor are saved.
Description
Technical field
The utility model relates to gutter technical field, and particularly gutter is used in a kind of colliery.
Background technology
In prior art, colliery is included in interim groove that roadway floor digs and the concrete ditch of interim flute surfaces with gutter.In use procedure, because Tunnel Pressure is larger, the concrete that waters irrigation ditch also can be stressed, produces the damage of breaking, and causes ditch easily to produce deformation failure.By after the mud cleaning of interim groove, also need again to adopt concrete casting, ability draining, the expense that wastes time and energy material.
Therefore, how reducing ditch cost, improve speed of application, solve after the damage of gutter, repair comparatively bothersome problem, is those skilled in the art's technical issues that need to address.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of colliery with gutter, after gutter is damaged, more easily repairs.
Gutter is used in the utility model colliery, be included in the interim groove that the roadway floor in colliery digs, wherein also comprise the percolation-proof belt being laid in described interim groove, and along the bearing of trend of described interim groove, the middle part of described percolation-proof belt is lower with respect to both sides.
The utility model colliery, with gutter, be connected, and the interval of two adjacent bolts is less than 1m on wherein said percolation-proof belt higher than the both sides at middle part by screw bolt and nut.
Gutter is used in the utility model colliery, and the length of wherein said percolation-proof belt is less than 20m, and the both sides of extending are along its length provided with described bolt.
Gutter is used in the utility model colliery, and wherein the lap length of two adjacent percolation-proof belts is greater than 200mm.
The utility model colliery is also fixed with nut by gutter a, side that is positioned at described percolation-proof belt inner side on wherein said bolt.
With respect to prior art, the colliery that the utility model provides is included in the interim groove digging on the roadway floor in colliery and is positioned at the percolation-proof belt of interim groove with gutter.And the middle part of extending along interim groove direction on percolation-proof belt is lower than the both sides of extending along interim groove direction, when current are during through percolation-proof belt, the both sides of percolation-proof belt can be overflowed by anti-sealing, make water only flow into appointed area along interim groove direction.
When after interim groove stress deformation, floating cash, float coal in interim groove are rooted out, repave percolation-proof belt, do not need percolation-proof belt to repair, time saving and energy saving, and save cost.
Below in conjunction with accompanying drawing, colliery of the present utility model is described further with gutter.
Brief description of the drawings
Fig. 1 is the structural representation of the percolation-proof belt in the utility model.

Percolation-proof belt-1, bolt-2, nut-3.
Detailed description of the invention
Core of the present utility model is to provide a kind of colliery of easily repairing and uses gutter.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the colliery that the utility model provides is included in the interim groove digging on the roadway floor in colliery and is positioned at the percolation-proof belt 1 of interim groove with gutter.And the middle part of extending along interim groove direction on percolation-proof belt 1 is lower than the both sides of extending along interim groove direction, and percolation-proof belt 1 is curved, matching with the shape of interim groove.When current are during through percolation-proof belt 1, the both sides of percolation-proof belt 1 can be overflowed by anti-sealing, make water only flow into appointed area along interim groove direction.
With respect to prior art, the utility model has the advantages that: when after interim groove stress deformation, floating cash, float coal in interim groove are rooted out, repaved percolation-proof belt 1, do not need percolation-proof belt 1 to repair, time saving and energy saving; The old belt that can use colliery, reduces costs; Working procedure is few, and efficiency is high.
Limited by percolation-proof belt 1 self-characteristic, it is difficult for keeping middle part low, the arc shape that both sides are high.Therefore, the both sides higher than middle part on percolation-proof belt 1 are connected with nut 3 by bolt 2.Bolt 2, through the both sides of percolation-proof belt 1, is bent into percolation-proof belt 1 after required arc shape, screws on nut 3.So arrange, can make percolation-proof belt 1 keep arc shape.
And preferentially select the interval of two adjacent screws to be less than 1m.In the time being greater than 1m, cannot make each position of percolation-proof belt 1 all keep arc shape.
Bolt 2 can be stud, all fixing with nut 3 in the both sides of stud, can be also single ended bolt.
For the distance between bolt hole and percolation-proof belt 1 edge of bolt 2 is set, can according to requirements specifically set.
Certainly, also can make percolation-proof belt 1 keep required arc by arc iron wire.By after iron wire embowment, percolation-proof belt 1 is arranged along arc iron wire, so that percolation-proof belt 1 reaches needed shape, i.e. arc.
Preferably, make the length of percolation-proof belt 1 be less than 20m, bolt 2 is arranged on to the both sides of extending along percolation-proof belt 1 length direction.Convenient mobile and laying percolation-proof belt 1 is so set.
While laying percolation-proof belt 1 along the upward slope direction of interim groove, a rear joint percolation-proof belt 1 is overlapped on to the top of last joint percolation-proof belt 1, and preferentially select the lap length of two adjacent joint percolation-proof belts 1 to be greater than 200mm, to prevent that water is from lap-joint's seepage.The zone face of overlap joint can adopt cutter equating whole, to ensure to overlap quality.
And a side that is positioned at percolation-proof belt 1 inner side on bolt 2 is also fixed with nut 3, percolation-proof belt 1 is fixed on bolt 2 by the nut 3 that lays respectively at percolation-proof belt 1 inner side and outside.So arrange, the percolation-proof belt 1 that can effectively prevent diverse location moves to the inside because of stressed difference, and then causes its distortion different, makes the phenomenon of its damage.
The inner side of percolation-proof belt 1 as herein described refers to a side relative with outside, and outside refers to the side fitting with interim groove.
The above embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
