Wherein, the flood pattern includes the water-feeding ＆ drainaging pipeline 112 being connected with detection well water filling port 11, in water-feeding ＆ drainaging pipeline
On be provided with valve 111.In water filling, it is directly injected into detection well by water filling port by water-feeding ＆ drainaging pipeline, immersible pump 12 is by the
Two lowering or hoisting gears 2 are delivered to below the liquid level in detection well, in draining, are completed by immersible pump.
Specifically, the first lowering or hoisting gear includes the first electric block 21 and the first steel driven by the first electric block 21
Cord 23, the second lowering or hoisting gear includes the second electric block 22 and the second steel wire rope 24 driven by the second electric block 22, the
The lift side of one steel wire rope 23 is connected with the top of instrument stan 4, and the lift side of the second steel wire rope 24 is connected with the top of immersible pump 12,
Device work in, two electric blocks, one as suspention instrument stan 4 use, another suspention immersible pump 12 use, immersible pump 12 by
Independent-lifting device cannot individually be taken out when lifting can avoid immersible pump 12 from breaking down the problem of maintenance.In the present embodiment
In, the immersible pump 12 of selection is single-phase Submersible Pump, metered flow 2m3/ h, rated power 0.37kW, lift is not less than
40m。
Because the range by inspection water-level gauge is different, the instrument for different ranges is needed in by inspection water-level gauge installation process
Device layering difference is installed, therefore instrument stan 4 includes some instrument baskets 41, and instrument basket 41 can go up lower leaf setting.But instrument basket that
This connection combination, it is also removable.
The normal water level measurement apparatus 3 of this Novel underground water pressure formula water-level gauge degree of accuracy detection means also include water-level gauge
Lowering or hoisting gear 32, normal water level meter 31 can be sent to the water level in detection well by the lift side of water-level gauge lowering or hoisting gear 32,
Water-level gauge lowering or hoisting gear is also adopted by electric block or manual lifting device.In the present embodiment, normal water level meter 31 is floating
Minor water-level gauge, need to periodically receive calibration operation.
When using this detection means, first, the instrument for different ranges carries out layering difference installation, actually detected mistake
Cheng Zhong, can simultaneously install 1-3 layers of instrument as needed in detection well 1.Specific mounting means is as follows：
In an installation, it is vertically arranged on instrument stan 4 by the underwater sensor of inspection water-level gauge, it is ensured that every sensor reliability
It is fixed, when will not be tested because of test in well SEA LEVEL VARIATION and cause displacement.
Before detection, the first steel wire rope 23 is discharged by by first electric block 21 of inspection water-level gauge lowering or hoisting gear 2, with first
The instrument stan 4 of the lift side of steel wire rope 23 connection is released to respective depth in detection well 1（Can multilayer release simultaneously）, by inspection water level
Meter signal cable（The cable containing ventilation）, drawing simultaneously fixed to well head, signal cable can meet RTU and carry out data output, by inspection water level
Well head and above ground portion the device unification of meter are fixedly placed in specified location.Meanwhile, immersible pump 12 is filled with by inspection water-level gauge lifting
The second rope 24 lift sides connection of 2 release of the second electric block 22 is put, and is suspended to Jing Zhong the superiors instrument stan top, kept away
Exempt from water level it is too low and cause the superiors by inspection water-level gauge surface.
After the completion of instrument is installed and places work, water filling first is carried out to detection well 1, carried out by inspection water-level gauge debugging, note
After the completion of water, normal water level meter 31 is fallen into test well, made in its immersion water surface, testing staff is by reading standard water
The numerical value of position meter carries out more than the three times measurements of standard water place value, averages, and each time of measuring interval is no less than 1h,
Debugging, calibration work after for being installed by inspection water-level gauge.After the completion of by inspection water-level gauge debugging, detection whole process must not be to instrument
Adjust again.
After detecting that preparation is ready more than, detection method is as follows：By inspection water-level gauge water-level gauge in gamut scope,
Adjustment water level variability is not more than 40 cm/min, makes one whole process of water level ascending, descending in detection well 1.Every meter of water level test point is no less than
One, reach measurement water level, stand 3min, wait water level it is steady after, record standard water level value and by inspection water-level gauge measured value.Mark
Quasi- water level value and it is the elementary error of water-level gauge by the difference of inspection water-level gauge measured value.
To be fixed in instrument basket by inspection water-level gauge, adjustment water level variability is not more than 40 cm/min so that water level unidirectionally rises
Or same water level point is unidirectionally down to, and it is repeated 5 times, reach measurement water level and stand 5min, after waiting water level steady, take that it is maximum, most
The difference of small measured value.This experiment selection carried out in three water level points being evenly distributed in gamut, record standard water level value and
By inspection water-level gauge measured value, the big person of its result is the repeatability error of the water-level gauge.
Because detection well is simulated by inspection water-level gauge scene applied environment, so for the detection method of the degree of accuracy, its base
This error can be introduced by the drift of inspection water-level gauge own temperature and time drift error, reach the purpose for detecting its composition error,
Can be reached from extension detection time in detection method, because water level can be that artificial change at any time controls in detection well
, on the basis of whole its elementary error of detection of water level ascending, descending one in detection well, increase detection time（10d or 1
Month）To verify the long-time stability by inspection water-level gauge.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned implementation method, also
Including being combined constituted technical scheme by above technical characteristic.It should be pointed out that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and moisten
Decorations are also considered as protection domain of the present utility model.
