Description
Technical field
The invention belongs to the soil erosion and a kind of experimental provision in scientific research for soil and water conservation field, and in particular to a kind of thin layer is equal
The uniform bypass channel of thin layer of even water sand analogue means.
Background technology
Soil erosion is global Significant Problems of Eco-environment, and sloping upland is the important source of soil erosion.It is domatic
Soil water erosion process can be analyzed to raindrop impact and runoff washes away destruction dispersion process to soil particle and runoff to soil
The handling process of grain.During slope water erosion, the runoff that earth's surface is formed generally carries a number of silt, with run-off
Continuous increase, this sediment laden flow has stronger erosiveness to soil below.Whether pooled according to sediment laden flow
Plume, domatic sediment laden flow can be divided into thin layer sediment laden flow and rill suspension current.Because thin layer sediment laden flow distribution area is big,
The silt of carrying is often the major part of the erosion caused by sloping surfaces, therefore it is research runoff from upslope that simulation is carried out to thin layer sediment laden flow
The basis of husky Soil Under Conditions Erosion Law.
In slope water erosion process study at present thin layer sediment laden flow is simulated frequently with Method of rainfall simulation.I.e. to experiment
Area directly carries out artificially-simulated rainfall and obtains thin layer sediment laden flow；This method preferably runoff caused by simulated rainfall can invade
Erosion, but operability is poor, and caused run-off silt content is uneven, and run-off and silt content are difficult to quantify, while is not easy to simulate
The thin layer sediment laden flow of larger flow.
The content of the invention
For in place of above shortcomings in the prior art, the technical problem to be solved in the present invention is to provide a kind of thin layer
The uniform bypass channel of thin layer of uniform water sand analogue means, its key problem in technology is to sheet silt carrying flow by the present apparatus（It is long
10cm, thickness are adjusted between 1-9mm）By two-stage shunting and unhurried current, the uniform water sand footpath of thin layer that width reaches 150cm is obtained
Stream.
The present invention is formed
A kind of uniform bypass channel of thin layer of the uniform water sand analogue means of thin layer, divides water by one-level bypass channel, two level sector
The uniform water sand drainage bag of groove, bypass channel frame, one-level area of slack water, two level area of slack water, thin layer, bypass channel bottom plate are formed, and it is special
Sign is：There is one-level bypass channel to be connected with two level sector bypass channel on bypass channel bottom plate, there is bypass channel frame on periphery, in two level
It is one-level area of slack water below fan-shaped bypass channel, is two level area of slack water below one-level area of slack water, two level is below area of slack water
The uniform water sand drainage bag of thin layer.
Left and right is divided into a plurality of water sand flowing groove A to the water sand groove dividing plate A that one-level bypass channel is erect by polylith side by side.
The water sand groove dividing plate B that two level sector bypass channel is erect by polylith is divided into a plurality of low wide and up narrow water sand drift by sector and moved
Groove B.
One-level bypass channel is process by groove aluminium, and two level sector bypass channel is process by aluminum corner brace.Compared with the prior art
Advantages of the present invention
The device for having done water sand Runoff Simulation at present mainly does the plume of rill erosion, has no the uniform water sand mould of thin layer
Intend the report of device.The present invention has equipment making cheap；Strong operability；Simulation width can be according to needing to set；Contain
Husky runoff in the one fixed width of analog machine all than it is more uniform the advantages that.
