The structure of soil liquid gatherer is: be provided with feeder, feeder inner bottom part is covered with stone, the surface of stone is covered with the nylon wire that two-layer above aperture is 0.5mm, on the front end face of feeder, be connected with drain pipe, the two ends of mozzle are communicated with drain pipe and sampling jar respectively, are provided with valve IV on mozzle, feeder is embedded in rectangular parallelepiped and contains in the soil in native pond, soil liquid gatherer is corresponding one by one with thief hole, the drain pipe of each soil liquid gatherer is contained thief hole corresponding in the sidewall III of Tu Chi and is tightly connected with this thief hole through rectangular parallelepiped, the long limit of feeder is parallel with the broadside that rectangular parallelepiped is contained Tu Chi, between adjacent two soil liquid gatherers of vertically arranging from top to bottom, the rear end face of the front end face of the feeder of the upper soil liquid gatherer that it is adjacent and the feeder of adjacent next soil liquid gatherer is being contained on the parallel same plane of the sidewall III of Tu Chi with rectangular parallelepiped,
Described rectangular parallelepiped Sheng Tu Chi, intake pool and discharge bay are integrated and are placed on underframe, and underframe inside casing is provided with a short beam parallel with the broadside of underframe, and short beam, over against sidewall I bottom surface, is provided with gradient regulator in the bottom surface of short beam.
Described gradient regulator is comprised of two Pneumatic jacks, and two Pneumatic jack intervals arrange, and two Pneumatic jacks withstand on the bottom surface of short beam.
Principle of work of the present invention is: the shower nozzle by water system is sprayed water to containing Tu Chi, form the Vertical Infiltration of soil moisture, by water system, to the intake pool in head water level control system, intake again, two Pneumatic jacks of gradient regulator are arranged under the underframe under intake pool sidewall, make in intake pool and Sheng Tuchi near the soil of intake pool higher than discharge bay soil near discharge bay and in Sheng Tuchi, form certain slope, to be nature enter Sheng Tuchi and to the infiltration of the discharge bay outflow of portalling by the infiltration hand-hole of intake pool to current, form the main lateral flow occurring of shallow ground water stream, and by being separately positioned on the head of intake pool lateral wall and discharge bay lateral wall, water level control punch and head, water level is controlled baffle plate, the height of adjustable shallow groundwater.Can be according to the height demand of water level, design head is controlled the height (F of baffle plate
1) size and water level control the height (F of baffle plate
2) size, control the height of water level.When water level need to be lower, head is controlled the height (F of baffle plate
1), water level controls the height (F of baffle plate
2) size can be less, can make to control height of baffle plate, water level higher than head and control the water of height of baffle plate and flow out from head, water level control punch.Otherwise while needing water level height a little, head controls the height of baffle plate, the height of water level control baffle plate can be high.Head, water level are controlled baffle plate and are covered respectively on head, water level control punch, although be to be tightly connected with the orifice edge of head, water level control punch respectively, make the water needing can be retained in pond, but while regulating head, water level height, head, the water level control baffle plate that need to change proper height are also easy, as remove sealing stick.
Therefore, the Vertical Infiltration process of soil moisture in the existing agricultural land soil hydrologic cycle of the present invention, have again under the current continuation in soil and ooze, penetrate in shallow ground water, the main lateral flow occurring of shallow ground water stream, and be accompanied by the process of certain perpendicular flow, therefore, the present invention can collect, monitor different soil with elements such as nitrogen phosphorus in the Vertical Infiltration process of soil moisture, can also collect simultaneously, monitor the lateral flow of main generation, and be accompanied by the elements such as nitrogen phosphorus in the shallow ground water flow process of certain perpendicular flow, overcome only the leaching process of the elements such as nitrogen phosphorus in soil moisture Vertical Infiltration process being observed that the Element leashing migration observation experiment devices such as nitrogen phosphorus in existing agricultural land soil exist, and can not be to the defect of observing with migration of elements processes such as nitrogen phosphorus in the main lateral stream occurring in shallow ground water flow process.Soil liquid gatherer of the present invention is arranged on the different levels of soil, when soil liquid gatherer is arranged on the soil layer of the stream of the shallow ground water from intake pool to discharge bay not, collection be the leaching liquor of the element such as nitrogen phosphorus in the Vertical Infiltration process of soil moisture.Due to up and down between vertical adjacent two soil liquid gatherers of vertically arranging, the rear end face of the feeder of the front end face of the feeder of the upper soil liquid gatherer that it is adjacent and adjacent next soil liquid gatherer is positioned on same vertical plane, thereby the feeder of upper and lower soil liquid gatherer does not block mutually, thereby, when soil liquid gatherer is arranged on the soil layer of the shallow ground water stream from intake pool to discharge bay, what collect is with the main lateral flow occurring of shallow ground water stream, and be accompanied by the migration of elements solution such as nitrogen phosphorus in the process of certain perpendicular flow.Therefore, the present invention not only can monitor under rainfall or irrigation conditions the element such as nitrogen phosphorus with the Vertical Infiltration process of soil moisture, simultaneously, can also according to the mobile feature of shallow ground water, (be mainly lateral flow, and be accompanied by certain perpendicular flow), monitoring is differently descended under height of water level, and the elements such as nitrogen phosphorus are with the transition process of Groundwater Flow.Therefore the present invention has reflected two parts that aforesaid agricultural land soil hydrologic cycle mainly comprises comprehensively, objectively, has made up and cannot monitor at present the elements such as nitrogen phosphorus with the migration problem of shallow ground water stream.This system not only can shorten the test period, reduces experiment work amount, reduces boundary effect, improve test accuracy, and data reasonable, science also can be provided for the Mechanism Study of farmland pollution of area source.
The present invention not only can monitor the elements such as nitrogen phosphorus, can also monitor other water-soluble other element.
