Description
Technical field
The utility model relates to a kind of handheld portable Karst Fissures water pressure measuring instrument.Be applicable to the underground workss such as Hydraulic and Hydro-Power Engineering, traffic, mine.
Background technology
Karst water claims again " karst water ", is the underground water in the corrosion space (such as solution cavity, solution crack, dissolution pore etc.) that is present in the solubility rock stratum.In the plains region and be subjected to some geologic structure to control formed charge for remittance area, because underground river, corrosion hole are grown and linked to each other, the distribution of karst diving is relatively even, and water level is also more shallow; And the mountain area of karst intense development, karst water is relatively concentrated and is present in the system of underground underground river, and underground water table is darker.Karst Fissures water is the underground water in existence and the karst region formation fractures, the characteristics of high mountain gorge Karst Fissures water are: the water yield abundant and disperse, degree of water-rich is uneven, mainly be stratiform karst piestic water, what it was different with the characteristics of general piestic water is that the water yield is large and moisture even.
Karst water is good resource of water supply, but to pit and underground structrue engineering construction, often causes disastrous unexpected water burst.When the excavation subterranean tunnel; often can run into less projective water point; in order to grasp the karst water enrichment degree; usually need to calculate fissure water pressure; mostly be to carry out inverting according to its jet length in the past, can not in time calculate fissure water pressure, time-consuming again effort; when running into the more tunnel of EXIT POINT, Karst Fissures water can become the key factor of control engineering construction safety, driving progress and even success or failure sometimes.Up to the present, during global deep-buried underground engineering was built, effective fissure water pressure measuring instrument was actually rare.Handheld portable Karst Fissures water pressure measuring instrument is one of effective instrument of measuring the conventional water pressure of Karst Fissures water in the deep-buried underground engineering.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, a kind of handheld portable Karst Fissures water pressure measuring instrument simple in structure, easy to carry is provided, provide rapidly for solving karst region deep-lying tunnel (tunnel, tunnel) fissure water pressure measurements, effectively, method and apparatus accurately, help solution construction safety, construction speed and engineering treatment measures problem.
The technical scheme that the utility model adopts is: a kind of handheld portable Karst Fissures water pressure measuring instrument, it is characterized in that: this measuring instrument comprises the uncovered box body of being made by rigid baffle, four sides of this box body top closely connects the flexible rubber circle, one side box body be shaped with handle; The ball crown type pressure transducer is housed in the described box body, and the pressure display screen that display ball crown type pressure transducer measurement data is equipped with at the box body back side is equipped with battery case and power switch on the handle.
The beneficial effects of the utility model are: handheld portable Karst Fissures water pressure measuring instrument is a kind of surveying instrument of original position, it is convenient, efficiently, characteristics can be improved the measuring speed of Karst Fissures water head greatly accurately, can access true, the most original water pressure data.Help to solve construction safety, construction speed problem, and provide foundation for the engineering treatment measures.

Embodiment
Such as Fig. 1 ~ shown in Figure 3, the present embodiment is a kind of easy to carry, and the handheld portable Karst Fissures water pressure measuring instrument that can measure in Karst Fissures water EXIT POINT original position, this measuring instrument mainly is comprised of flexible rubber circle 1, ball crown type pressure transducer 2, handle 3, battery case 4, rigid baffle 5, display screen 6 and power switch 7 etc.Wherein five rigid baffles 5 are made the box body of a uncovered, and four sides tops of box body closely are connected with flexible rubber circle 1, and a side of this box body is shaped with handle 3.Ball crown type pressure transducer 2 is installed in the described box body, and pressure display screen 6 is equipped with at the box body back side, is used for the data that display ball crown type pressure transducer 2 is measured gained.Be shaped with battery case 4 in described handle 3, the battery of packing in the battery case 4 can be ball crown type pressure transducer 2 and pressure display screen 6 etc. power supply is provided, and the power switch 7 of control battery case 4 interior on/offs also is installed on handle.
Fig. 4 is the circuit connection diagram of the present embodiment, and ball crown type pressure transducer 2 is integrated on the same circuit board 9 with pressure display screen 6 in this example, and battery case 4, power switch 7 and circuit board 9 are through wire 10 serial connections.The present embodiment Instrumental operating voltage is 1.5V, and working current is 2600mAh, and the water pressure sensor maximum range is 1Mpa.
The concrete using method of the present embodiment is as follows: in the battery case 4 of at first battery being packed into, and turn on the power switch 7, when pressure display screen 6 shows " 0.000 ", prove that the instrument power supply is sufficient, can normally use, if glimpse or digital color is dim please change battery.The arrangement of crag around the EXIT POINT is comparatively smooth, and clean up.Ball crown type pressure transducer 2 is aimed at Karst Fissures water water delivering orifice, and crag is pasted in flexible rubber collar 1, makes rubber inner wall wrap whole EXIT POINT, if EXIT POINT is irregularly shaped, available sealing coating becomes regular shape with its shutoff, measures again.Hold on the other hand handle, the another hand is firmly pressed rigid baffle 5, dynamics is appropriate, guaranteeing on the one hand that crevice water does not ooze out around the flexible rubber circle 1 gets final product, guarantee that on the other hand ball crown type pressure transducer 2 does not contact with crag, make watertight in rubber ring, until reading change less or stable after, the numerical value that display shows is the fissure water pressure size of this point.
For tunnel (tunnel, tunnel) engineering, sometimes need more accurate fissure water pressure data, provide scientific basis with convenient for recharging to process, can get its mean value by the above-mentioned steps repeated measurement several times, be worth more accurately to obtaining.
Ball crown type pressure transducer 2 described in the present embodiment is the commercially available prod with pressure display screen 6, is conventional sensor signal display circuit between the two, therefore do not do to launch to introduce.
