Description
Technical field
The invention belongs to underground water level measurement field, be specifically related to one and descend level measurement device and measuring method simply.
Background technology
At present in landslide monitoring field, the monitoring of underground water table is a very important aspect, but not only expensive for the equipment of monitoring underground water table at present, and its Monitoring Data is inaccurate.Also there are some simple measurement tools on the market, these simple measurement tool majorities whether touch water by people's perception surveying instrument, and its precision is not high, and measurement data is also inaccurate.
Summary of the invention
Cost is low, measurement data descends level measurement device and measuring method accurately simply to the object of the present invention is to provide one to measure.
The present invention is achieved in that
One descends level measurement device simply, comprise multimeter, electric wire and pouring weight, described multimeter comprises multimeter dial plate and pen meter of universal meter, described pen meter of universal meter comprises faucet section and test pencil section, described faucet section is connected with test pencil section by electric wire, and the junction of electric wire and faucet section, test pencil section is provided with the adhesive waterproof tape preventing short circuit; Described pouring weight and test pencil section bundle, and the nib of described test pencil section stretches out the lower surface of pouring weight, and the nib of described test pencil section is in same level;
The end of described electric wire and the upper surface central contact of pouring weight, and described electric wire is provided with scale;
Because underground water table is general darker, measure electric wire piecemeal easily to make mistakes, error easily accumulates, and wastes time and energy, therefore a scale can be done at the exocuticle of electric wire every 1 meter, often whole 5 meters or whole 10 meters time, change scale shape, during measurement, just first can count the scale of whole 5 meters or whole 10 meters, count the scale of whole rice again, finally by the wire length of inadequate 1 meter of tape measure, substantially reduce the workload measuring electric wire, also reduce error rate and error.
During use, multimeter is got to the shelves of measuring resistance, and its range is not too big, now multimeter both can have been powered and also can be used as detection instrument, when test pencil detects the water surface, form loop, pointer deflects, the moment pointer that test pencil leaves the water surface returns, and now corresponding wire length is exactly the degree of depth (earth's surface is to the degree of depth on underground water surface) of underground water table; Due to only just meeting power consumption, therefore very power saving after the test pencil contact water surface.
Further scheme is: described pouring weight is good with thin short severe one, and diameter is 10mm, length is 10cm reinforcing bar or screw can be selected as pouring weight.
Further scheme is: described electric wire is by wire spool folding and unfolding.
For avoiding electric wire in measuring process be not straightened or draw elongated, described electric wire should be enough soft, and retractility is little, and general copper core just can meet the demands; Low temp area monitoring time, electric wire should be low to temperature susceplibility, prevents temperature too low, and electric wire cannot be stretching easily by pouring weight, affects measuring accuracy.
The invention also discloses a kind of underground water level measurement method, comprise the steps:
(1) select multimeter, electric wire, pen meter of universal meter centering is cut into two sections, and one section is faucet section, and another section is test pencil section, faucet section is connected with test pencil section, is pasted joint with adhesive waterproof tape, prevent short circuit with electric wire;
(2) diameter is 10mm, length is 10cm bar dowel or screw is chosen as pouring weight;
(3) pouring weight and test pencil section are bundled, the nib of test pencil section must be in equal height, so that two test pencil nibs contact the water surface simultaneously; Electric wire termination is fixed on the central authorities of pouring weight upper surface, when ensureing that test pencil nib stretches into hydrology hole, pouring weight is plumbness;
(4) to paint on surfaces of wires or adhesive tape does scale, scale starting point in two test pencil nib line midpoint, every 5 meters or every 10 meters of patterns changing scale;
(5) faucet section is inserted on multimeter dial plate, resistance gear got to by multimeter, test pencil section is slowly put into hydrology hole, unwrapping wire number scale on one side on one side, when seeing that multimeter pointer starts to deflect, the degree of depth corresponding to electric wire is exactly the degree of depth of earth's surface to underground water surface, records this depth data; At critical groundwater table place, electric wire slowly risen, slowly decline several times again, observe needle deflection, record each depth data; Above-mentioned depth data is averaged, draws underground water table data;
(6) by wire spool, electric wire is slowly packed up; Complete a hydrology hole underground water level measurement.
In the present invention, described electric wire should soft, have insulated hull outward, temperature susceplibility is low, and retractility is little, is mainly used in the line length lengthening pen meter of universal meter; Whether multimeter touches the water surface for responding to test pencil, and pouring weight lies in test pencil section, for by electric wire straightening.The necessary volume of described pouring weight is little, average weight, this is because pouring weight volume is easily stuck in too greatly in hydrology boring, weight is too little to be difficult to electric wire straightening, and pulling wire then can obtain too greatly elongated by weight, weight too little or too big city affect measuring accuracy, usually diameter is selected to be 10mm, the reinforcing bar of long 10cm or the screw of similar size, when monitoring on the spot, the selection of pouring weight can be acted as one sees fit according to above-mentioned requirements, is not strict with.
The invention has the advantages that: cost is low, lightweight, volume is little, be easy to carry; Device used is all that conventional device, cost of manufacture are low, easy to make, and not only measuring accuracy is high but also can reuse; Measuring method simple possible.
Accompanying drawing explanation
