Embodiment 1
The utility model provides a kind of measuring flume for slope soil erosion measurement, primarily directed to loess hill
The measurement problem of the slope soil erosion amount of Gullied, specifically as shown in figure 1, including upper groove body 1 and lower groove 2, the He of upper groove body 1
2 stepped arrangement of lower groove, upper groove body 1 are located at the oblique upper of lower groove 2, and upper groove body 1 and lower groove 2 are rectangle and vallecular cavity
Size it is identical.In the present embodiment, the length and width of vallecular cavity, it is deep be respectively 300cm, 50cm, 50cm, the reason for selecting this size
It is that wide average out to 15m in a certain regional slope or so is shown according to the analysis result of conventional data, long domatic runoff volume is
20m3Left and right, select to be used as measurement point at 1/5th of the analysis result, then have selected long 300cm, wide 50cm.Upper groove body 1
Foreboard and the foreboard of lower groove 2 be provided with multiple osculums 3, a diameter of 0.1mm of osculum 3, in this programme, draining
The effect in hole 3 is to discharge all soil grains and moisture that particle diameter D is less than 0.1mm, and soil grains of the particle diameter D more than 0.1mm is stayed
In upper groove body, meanwhile, excessive if there is flow, the osculum 3 on upper groove body 1 can not drain the silt of smaller particle in time
When, it can be screened and be discharged by lower groove 2, prevent from influenceing the accuracy of result because of excessive, in addition, selection row
A diameter of 0.1mm in water hole 3 be based on the different sand grain sizes mentioned in background technology content how much, selection
0.1mm ensures that the soil grain of big particle diameter will not be too many, passes through such side again in order to both guarantee to choose the soil grain of big particle diameter
Formula make it that what is retained in upper groove body 1 and lower groove 2 is essentially all the soil grain of big particle diameter, the soil grain for figuring big particle diameter
Work for, reduce or remit complexity screening link, greatly reduce workload, be allowed to simple and easy to do, the foreboard of upper groove body 1 with
The back plate of cell body 2 is located on same vertical plane and is connected as a single entity, and two side plates of upper groove body 1 extend forward one section upwards respectively
Distance, the silt that extension can ensure to overflow from upper groove body 1 can be all discharged in lower groove 2, two of upper groove body 1
Two side plates of side plate and lower groove 2 on same vertical plane and are connected as a single entity respectively.
Further, two supports that can adjust angle are provided with the outer wall of the back plate of lower groove 2, support includes bearing
4 and supporting leg 5, bearing 4 and supporting leg 5 be flexibly connected by clamping knob, supporting leg 5 has two.It is typically domatic to have inclination
Degree, the back plate of upper groove body 1 are also required to an angle when being adjacent to domatic, only need to adjust the angle can of supporting leg 5 herein
Realize the inclination of measuring flume.
When whole measuring flume is in obliquity, in order to allow short grained silt to discharge upper groove body 1 and lower groove as early as possible
2, in the present embodiment, multiple osculums 3 are provided with two side plates of upper groove body 1 and two side plates of lower groove 2, it is multiple
Osculum 3 have it is multiple rows of, often arrange osculum 3 number have it is multiple.
Operation principle：
Need to measure soil erosion amount it is domatic on according to domatic angle of inclination set the angle of inclination of supporting leg 5 to make
Upper groove body 1 back plate be adjacent to it is domatic, so as to receive silt, after the buffer-precipitation of upper groove body 1 and lower groove 2, groove in measurement
The gross weight W for whole soil grains of the particle diameter D more than 0.1mm that body 1 and lower groove 2 deposit0.1；Original soil sample does particle diameter before taking erosion
Analysis, calculate the percentage B shared by soil grains of the particle diameter D more than 0.1mm0.1；The gross weight for being then etched soil is：
Wt=W0.1/B0.1
Finally the ratio of width domatic according to where measuring flume calculates whole domatic soil erosion amount.
Embodiment described above is only the preferable embodiment of the utility model, and the scope of protection of the utility model is not
It is limited to this, any those skilled in the art can become apparent in the technical scope that the utility model discloses
Technical scheme simple change or equivalence replacement, belong to the scope of protection of the utility model.
