Description
Technical field
The present invention relates to hydrology experimental study technical field, in particular to a kind of horizontal rotation squeezes acquisition interflow dress
The control method set.
Background technique
Under the double influence of climate change and mankind's activity, profound change occurs for watershed hydrologic cycle differentiation.Weather becomes
Changing influences hydrologic cycle by changing precipitation, temperature, sunshine, wind, relative humidity etc., and then changes precipitation, runoff, evaporation, soil
The spatial and temporal distributions of the hydrographic features such as earth humidity.Mankind's activity, which then passes through, changes watershed system and the spatial and temporal patterns of water etc.
Influence hydrologic cycle process.Therefore response relation or different gradient, rain of the soil moisture content transformation to runoff during the rainfall
By force, underlying surface needs the response relation of runoff to carry out relevant research work, this be also current hydrology research hot spot it
One.
In current research work, research of the soil water movement to runoff response relation mostly uses designed, designed
Soil box, used artificially-simulated rainfall process, observes the transport conditions of soil wetting front and its sound to rainfall in soil box indoors
It should be related to.But the design most four of this soil box is thorough to be welded with steel plate, it can not be from the variation feelings of external observation soil moisture
Condition is only capable of utilizing the state change for burying the data understanding soil moisture that moisture transducer obtains from soil.The receipts of interflow
Collection is also collected only with single guiding device, can not the interflow to different depth carry out layering collection.
Improved device can be used for research of the related fields for Soil Moisture Movement state, can be layered and collect different soil
The interflow of earth depth, and the migration state of soil wetting front is observed in real time.For hydrology field, using the device to not
Rainfall diameter stream and the response relation of interflow under the same gradient, raininess, vegetation coverage.It equally, can for water and soil conservation aspect
By the control during improving the design of front end guiding device and banketing to the soil weight, soil is invaded during simulated rainfall
Erosion state.
Although the device of the existing motion conditions that soil moisture is directly observed by glass window makes observation more intuitive,
But the moisture movement inside soil is more complicated, glass window only reflects the part fact, and cannot be accurately to naked eyes
Soil wetting front situation inside the soil horizon that can't see is shown.

Gluing, to prevent interflow from entering lower layer's guiding device by the hole of steel disc and guiding device junction.Meanwhile steel disc and iron
The hole at the network chain place of connecing also needs to be sealed with glass cement, to prevent interflow from entering lower layer by the hole of steel disc and iron net junction
Guiding device.Vertical runs are between soil and iron net from bottom to top for spun yarn net, to prevent the soil side leakage in rainfall.
During banketing, water-tight device first is spread in bottom, and the junction of itself and trough surrounding is sealed with glass cement,
Prevent moisture from flowing out from soil box bottom.Then waterproof cloth upper berth 10cm fine sand and be compacted, then spread on sand
One layer of gauze finally carries out upper layer again and bankets to prevent upper layer of soil from mixing with lower layer sand.It can be according to specific during banketing
Requirement of experiment, the control soil weight carry out layering and banket.
Artificially-simulated rainfall is to the Response Mechanism for producing confluence under the conditions of the present apparatus realizes large scale in rainfall, simultaneously
There is important meaning to the research of the response relation of runoff to soil moisture content transformation, different gradient, raininess, underlying surface under change condition
Justice.
