Description
Technical field
The present invention relates to a kind of analogue experiment installation, relate in particular to a kind of analogue experiment installation for three-dimensional infiltration flow field monitoring.
Background technology
Gravity is the mobile motive power of natural fluid, and its head difference of bringing is the drive force source of infiltration current.Theoretical and experience showed in the past, and pumped well surrounding underground water confluxes to well, can form the groundwater level cone of depression centered by pumped well, higher away from the water level of pumped well, thereby underground water is confluxed in well by surrounding.
In the prior art, the measurement of pumped well and periphery water level thereof is adopted to observation well more, a plurality of observation wells are separately positioned in the different distance of pumped well, by disposable observation, obtain waterlevel data.Work as evidence, no matter pumped well around underground water is in diving or in artesian water state, underground water not only confluxes in well, also there is motion from top to bottom simultaneously, existing observed pattern cannot be correct the vertical change of reaction water level, cause observation to occur error, the precision that impact is measured.Especially in laboratory proofing and process of the test, this error may have a strong impact on the correctness of observed result, brings conclusion mistake.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of analogue experiment installation for three-dimensional infiltration flow field monitoring, it has changed forefathers and the observation well in different distance around pumped well has been carried out to the way of disposable observation mean water, realized can be simultaneously to each observation well real-time monitored of the SEA LEVEL VARIATION of a plurality of observation points from top to bottom, realized three-dimensional (3D) monitoring to pumped well underground water infiltration around flow field situation.

For an analogue experiment installation for three-dimensional infiltration flow field monitoring, comprise simulation box, pumped well, limnimeter, observation well, pressure measurement row; Described pumped well and described observation well are arranged in described simulation box; Described limnimeter connects described pumped well; Described observation well is arranged on described pumped well surrounding, and described pressure measurement row connects described observation well.
Many piezometer tube are drawn together in preferred described pressure measurement package.
In preferred described observation well, be provided with sighting tube.
On preferred described sighting tube, be provided with a plurality of peepholes, described peephole is along the axial distribution of sighting tube.
Preferably described in each, peephole connects respectively a described piezometer tube.
The invention has the advantages that: simple in structure, it is convenient to implement, can realize three-dimensional (3D) monitoring of pumped well underground water infiltration around flow field situation, the precision of monitoring result is compared existing observed pattern and is improved a lot.
