Good meets requirement of engineering.
At present the country existing device current situation and there are the problem of：
It is observed in work in groundwater level at present, the equipment of forefront is water-stage transmitter, and operation principle is：
By built in pressure sensor, probe is placed in the following constant depth of water level, instrument oneself will record its suffered absolute pressure, with
Local standard atmospheric pressure subtracts each other as its suffered water column pressure, water-column is being subtracted with constant depth, so as to converse underground
Water depth to water.But during bailing test, the underground water in well is with the operating of water pump, and water level is under faster speed
Drop, when water pump stops pumping, water level is risen again with faster speed, during the two, the pressure in well inside underground water
It will appear exceptional value, the depth to water come out at this time with the conversion pressure is with actually differing greatly.In pump process, need by
The time interval of code requirement measures groundwater level, and according to field measurement, water level decreasing is quickly, same within initial a few minutes
Tens centimeters bigger than the depth to water of manual measurement or even several meters of the depth to water of moment automatic recording instrument conversion, illustrates this mistake
Pressure value in journey in well inside underground water reduces extremely, it is possible to understand that underground water is in the process in weightless shape in well
State, such effective acceleration of gravity reduce, and cause pressure value less than normal, converse the depth to water come with regard to big.It is equally extensive in water level
At multiple initial stage, there is the process rapidly risen in underground water in well, causes sensor pressure value bigger than normal again in this way, converses what is come
Depth to water becomes smaller, though in the relatively slow change procedure of groundwater level, automatic recording instrument conversion depth to water also with
There is the error of Centimeter Level, this brings serious the data of manual measurement to the accuracy and reliability of field operation initial data
It influences, therefore the automatic water level of built in pressure sensor is recorded in bailing test water-level observation and does not apply to.
Water-level observation in bailing test at present is still based on artificial water-level observation instrument, because it is relative to expensive
It is more economical practical for automatic recording instrument, and observe data accurately and reliably.But during Practical Project use, find existing
There are poor anti jamming capabilities for somebody's work water-level observation instrument, larger in drawdown, and popping one's head in can not judge that probe is during decline
It is no a certain depth is blocked the problems such as：
（1）It is poor to cheat interference performance：Since there are hydraulic jump phenomenons with water level outside well for water level in well, allowed in this way in hydraulic jump
In the range of underground water can cause in the bigger stratum of permeability from the situation in borehole wall mesh access wall, such case
In the increase of hydraulic jump section, therewith depth, the outer underground water pressure of well is bigger, the feelings that flow is spurted into from mesh in well occurs
The positive and negative anodes unicom of probe, alarm " abnormal sound " can be made the observer to lack experience take for having arrived by condition, the flow of injection
Up to water level, so as to the water level information of misregistration.
（2）Probe is stuck：Due to the well construction that draws water, there are complexity, there are the feelings being stuck during probe declines
Condition, when descending depth of popping one's head in is smaller, observer may determine that out such case by the variation of lining rope weight,
But with the increase of drawdown, when probe is declined to a certain extent, the proportion that the weight of probe accounts for lining rope weight is less and less, this
When observer only with feel can not judge probe whether block.
Invention content
