Description
Technical field
The utility model relates to pit retaining monitoring field, especially a kind of self registering Digital water level meter.
Background technology
In pit retaining monitoring field, water level monitoring is one of monitoring parameter that must survey.In engineering monitoring, the sedimentation and deformation of the change of the change remote effect foundation pit supporting construction lateral wall pressure of water level and periphery pipeline, build/structures, this parameter is the important reference parameter of safe construction.Existing level measuring instrument mainly contains steel ruler water-level gauge and osmometer.
Steel ruler water-level gauge utilizes the principle of " underground water conduction ", after the probe contacts water surface, connects hummer power supply, thus reads Ground-water level from drop-down steel ruler; But this apparatus measures needs are read by manually surveying, record, are not easy to operation and cannot ensure data validity, cannot measuring in the liquid that electric conductivity is weak.
Osmometer directly measures hydraulic pressure, utilize hydraulic pressure and water column linear relationship (
), assist gas pressure, temperature adjustmemt measure Ground-water level indirectly simultaneously.This testing tool is in the measurements because belonging to indirect inspection, and corrected parameter is more, and measuring accuracy is relatively low, and does not have below upstream face too much or very fewly all can cause larger measuring error at osmometer, when water level can have osmometer, cannot carry out level measuring.
With reference to above water-level gauge equipment of the prior art, its major defect existed is:
(1) operation inconvenience, measurement data authenticity is poor: steel ruler water-level gauge need after the Ground-water level of location artificial survey read, record, operation inconvenience, easily error of omission, misdescription, cannot stop data forgery;
(2) scope of application is little: steel ruler water-level gauge cannot measure water level depth in weakly conducting liquid, easily causes and survey by mistake in humidity comparatively overall situation; Osmometer cannot be measured when the following degree of depth in water level face is less;
(3) measuring accuracy is low: steel ruler water-level gauge all triggers " hummer " below water level face and water level face, thinks and is difficult to judge the concrete degree of depth of water level; Osmometer need carry out temperature, air pressure correction when testing pore water pressure, affects simultaneously, cause measuring accuracy poor by cable, probe size;
(4) transmission mode is single: after osmometer has been measured at the scene in conjunction with frequency readings instrument, and frequency readings instrument need be connected with computer by USB or serial ports, thus carry out data transmission, transmission mode is single.
(5) can not intelligent monitoring be carried out: steel ruler water-level gauge and osmometer all cannot realize automatic collection, all need manual intervention to carry out data acquisition.
