Abstract
The utility model discloses a tandem type observing system for an underground high-water-pressure and high-flow water flow. The system comprises underground drainage drill fields, drill field inner walls, side walls, top plates and bottom plates which are subjected to anti-seepage treatment; a sealing wall body is circularly built in front of each drill field; a rectangular or triangular weir crest is arranged in the middle of the wall circularly built in front of each drill field; and a scaleplate is placed in each weir crest and at the zero point of the water level in each weir crest; and a drainage ditch is arranged below front of the drill field in a roadway, can collect water discharged from the drill fields and discharges the water to a water trough at one end of the roadway in a unified manner. The rectangular weir or the triangular weir formed in the wall in front of each drill field is adopted, so that the negative influences of blocking caused by crushed stones brought by open hole parts of drill holes when a pipeline flowmeter is used for measuring the water flow can be prevented. The system has the advantages that the structure is reasonable, the operation is simple, the flow is easy to observe during underground high-water-pressure and high-flow drainage, and the unified management of the water resource is facilitated.

Technical field
The utility model relates to the flow measuring system that not affected by crushed stone when the large flow of the high hydraulic pressure in a kind of water yield tandem recording geometry, especially down-hole discharges water.
Background technology
Mine, in mining process, often needs hydrophobic step-down to guarantee safe back production, after utilizing unrestrained boring to finish hydraulic pressure observation, need carry out outflow test.Because dewatering orifice hydraulic pressure is large, the water yield is large, and because affected by the naked hole of basement rock, in water with the fragment of different-grain diameter, utilize the pipeline flowmeter measurement of discharge, easily stop up breaking plant, designing a kind of current surveying device that not affected by fragment, is the task of top priority that solves the large flow outflow test of mine down-hole.
The utility model content
The technical problems to be solved in the utility model is to provide the large flow water yield of the high hydraulic pressure in a kind of down-hole tandem recording geometry, the Flow Observation when the down-hole large flow of high hydraulic pressure is discharged water.
The utility model is achieved through the following technical solutions.
The large flow water yield of the high hydraulic pressure in a kind of down-hole tandem recording geometry, comprise the down-hole drill site that discharges water, drill site Li Qiang, Bang Qiang, top board and base plate are all done antiseepage and are processed, drill site the place ahead circle is built the sealing body of wall, the drill site circle is provided with a rectangle or triangle crest of weir in the middle of building front wall, place scale in crest of weir to weir middle water level zero point, in tunnel, the drill site front lower place is provided with trench drain, and tunnel one end is provided with tank.
Further, above-mentioned boring consists of naked hole, sleeve pipe, water pressure gauge and spherical water valve.
The utility model has the advantage of:
1, simple in structure, easy to operate, easily the large flow water yield of the high hydraulic pressure in down-hole is observed;
2, drill site Li Qiang, Bang Qiang, top board and base plate are done the antiseepage processing, and the place ahead circle is built the sealing body of wall, can reach the effect of settling basin;
3, the drill site front wall arranges crest of weir, according to rod reading in weir, can directly calculate the water yield;
4,, by crest of weir measurement of discharge in the drill site front wall, easy device is taked in boring, in the time of can avoiding utilizing pipeline instrumentation flow by boring crushed stone that naked bore portion is brought into to negative effects such as it result in blockage;
5, the water unification that in tunnel, the trench drain of drill site front lower place can be discharged each crest of weir is discharged to the tank of tunnel one end, is conducive to the unified management of water resource.

Embodiment
For making goal of the invention of the present utility model and advantage more clear, below in conjunction with accompanying drawing, the utility model is described in further detail.
The structural representation that Fig. 1 is the large flow water yield of the high hydraulic pressure in the utility model down-hole tandem recording geometry.The structural representation that Fig. 2～Fig. 4 is drill site, boring and triangular-notch weir in this recording geometry.With reference to Fig. 1～Fig. 4, the utility model, the large flow water yield of the high hydraulic pressure in down-hole tandem recording geometry, to utilize the down-hole drill site 2 that discharges water, after wall in it 6, base plate 10, nation's wall 11 and top board 12 are done to water proof antiseepage processing, build certain altitude sealing body of wall 7 at its place ahead circle, and by some scale, a rectangle or triangle crest of weir 8 are set therebetween.When dewatering orifice 5 discharges water, carry crushed stone in hole and be deposited in the drill site bottom, the water flowed out by rectangular weir or triangle crest of weir 8 is by the interior drill site 2 unified tanks 3 that are discharged to tunnel one end in trench drain, front lower place 4 in tunnel 1.In addition, utilize ruler 9 can measure the water level over crest of weir 8, and be converted into water yield value.
The utility model, the large flow water yield of the high hydraulic pressure in down-hole tandem recording geometry, simple in structure, easy to operate, can directly calculate the water yield according to water level reading on scale 9 in drill site 2 front wall crests of weir 8, easily the large flow water yield of the high hydraulic pressure in down-hole is observed.By crest of weir 8 measurement of discharges in drill site 2 front walls, hole and 5 take easy device, while having avoided utilizing pipeline instrumentation flow by the naked hole of boring 13 crushed stone that part is brought into to negative effects such as it result in blockage.Drill site 2 surroundings and front wall 7 are all made antiseepage, encapsulation process, can reach the effect of settling basin, and the water unification that trench drain 4 can be discharged each crest of weir 8 is discharged to the tank 3 of tunnel one end, all is conducive to the unified management of water resource.
Above-mentioned example is only explanation technical pattern of the present utility model and characteristics, and all equivalences of doing according to the utility model system essence change or modify, and all should be encompassed in protection domain of the present utility model.
