Abstract
Disclosed is a three-dimensional seepage flow field monitoring method of a pumping well. A level meter is arranged in the pumping well to monitor the water level of the pumping well, an observation well is arranged around the pumping well, and an observation pipe is arranged in the observation well and provided with a plurality of observation holes distributed along the axis of the observation pipe. A plurality of pressure measuring pipes are arranged on the ground, each pressure measuring pipe is connected with one observation hole, the pumping well pumps water, and the water around flows to the center to form a seepage flow field. The water level of the pumping well is monitored through the level meter, the water head variation of each observation hole in the observation well is monitored through the pressure measuring pipes, and three-dimensional monitoring on the seepage flow field is achieved. By utilizing the obtained data, a three-dimensional flow field graph is drawn through a computer and corresponding drawing software.

Description
Technical field
The present invention relates to a kind of flow field monitoring method, relate in particular to a kind of monitoring method that is applied to 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 inspection well more, a plurality of inspection 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 piestic 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.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of three-dimensional infiltration flow field monitoring method, it has changed forefathers and the inspection 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 inspection well real-time monitored of the SEA LEVEL VARIATION of a plurality of observation stations from top to bottom, realized three-dimensional (3D) monitoring to pumped well underground water infiltration around flow field situation.
Technical scheme of the present invention is as follows:
A three-dimensional infiltration flow field monitoring method arranges limnimeter to monitor its water level in pumped well; At pumped well, around inspection well is set, in inspection well, is lowered to sighting tube, on sighting tube with a plurality of observation ports that distribute along its axis; Many piezometric tube are set on ground, and every piezometric tube connects an observation port; Pumped well draws water, and formation infiltration flow field is collected at surrounding current direction center; By limnimeter, monitor the water level of pumped well, by the change of water level of each observation port in many piezometric tube monitoring inspection wells, realize the three-dimensional monitoring to infiltration flow field; Utilize the data that obtain, by computing machine and corresponding mapping software, drawing three-dimensional flow field figure.
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.
Accompanying drawing explanation
Accompanying drawing 1 is the layout vertical view of inspection well in monitoring method of the present invention;
Accompanying drawing 2 is for the A-A that arranges vertical view in accompanying drawing 1 is to cut-open view.
Reference numeral is as follows:
1-stratum; 2-pumped well; 3-sighting tube (being arranged in inspection well); 4-observation port.
Embodiment
Mode below by embodiment is described in further detail monitoring method of the present invention.
The three-dimensional infiltration of pumped well flow field monitoring method first arranges limnimeter to monitor its water level in pumped well; Simultaneously at pumped well, inspection well is set around, inspection well has 24, is cruciform and is evenly arranged in the surrounding of pumped well and gos deep into stratum, is lowered to sighting tube in inspection well, on sighting tube with 10 along the equally distributed observation port of its axis; Many piezometric tube are set on ground, and every piezometric tube connects an observation port, and many piezometric tube can be connected in parallel and form pressure measurement row to obtain more intuitively the trend of head conversion.
When pumped well draws water, formation infiltration flow field is collected at surrounding current direction center; Now by limnimeter, monitor the water level of pumped well, by the change of water level of each observation port in many piezometric tube monitoring inspection wells, realize the three-dimensional monitoring to infiltration flow field; Utilize the data that obtain, by computing machine and corresponding mapping software, drawing three-dimensional flow field figure.
The above; it is only preferably embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with in technical scope that those skilled in the art disclose in patent of the present invention; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of patent of the present invention.
