Detailed description of the invention
Fig. 1 is the explosive view of the utility model test flume；
Fig. 2 is 45 top views of the utility model test flume；
Fig. 3 is end cover mounting structure schematic diagram；
It is as shown in the figure: baffle 1, plug 2, stainless drill rod 3, end cap 4, water outlet 5, cover board 6, edge 601.
Specific embodiment
With reference to the accompanying drawing and pass through specific embodiment further instruction the technical solution of the utility model includes:
Embodiment 1
A kind of portable test flume applied to field rain test as shown in Figures 1 to 3, it is desirable to provide a kind of energy is convenient
Dismantle, install and the carry while adjustable test flume of spatial dimension.According to above-mentioned requirements, several baffles 1 of this test flume
It is formed with an end cap 4, specific structure, principle and application method are as follows.
As shown in Figure 1, the range of this test flume is limited by baffle 1,1 end face of baffle is equipped with plug 2.It is patching simultaneously
Fixation hole configurations are provided on first 2.In use, being entered in the fixation hole of plug 2 by stainless 3 intercalation of drill rod, so that adjacent
Two baffles 1 are relatively stable.1 material of baffle is stainless steel, can arbitrarily be separated and be combined by stainless drill rod 3, thus shape
At the test space of different size or shape.
As depicted in figs. 1 and 2, the space structure that several baffles 1 are formed is bonded by end cap 4.Gear is installed in end cap 4
On plate 1,4 edge of end cap is equipped with fixation hole configurations, by stainless 3 intercalation of drill rod enter to make in fixation hole baffle 1 and end cap 4 it
Between it is relatively stable.The effect of end cap 4 is to provide for a water outlet 5, i.e., a water outlet 5 is provided on end cap 4.Going out
Mouth of a river position be arranged lower edge, to reduce runoff during collection caused by loss.
The structure of end cap 4 is as shown in figure 3, be inclined cover board 6 in 4 upper surface of end cap.The effect of cover board 6 is can to prevent it
Top rainfall falls into trial zone, influences the accuracy of test.For the discharge for making 6 top waterflow stabilization of cover board, cover board 6 is arranged
For incline structure.And least significant end is located at water outlet 5.The edge 601 that setting prevents water flow side from revealing on cover board 6 simultaneously,
So that water flow is only discharged above water outlet 5.
In the present apparatus, the length of stainless drill rod 3 need to be greater than the height of baffle 1 and end cap 4.In use, need to be stainless by part
Drill rod 3 is inserted into soil, while to guarantee that baffle and earth's surface fit closely, can be effectively prevented rainwater and side leakage or rain occurs
Drop, which is hit, splashes caused structural instability.
Specific mounting structure step: before implementation, the size and quantity of baffle 1 are determined according to space needed for testing.When implementation,
The first fixed baffle 1 since trial zone front end (4 one end of end-cover-free).Then, successively splice from two sides, and in time with stainless drill rod
3 are fixed.Then, in trial zone rear mounting end lid 4.Finally, when whole device installs, then tamp it is primary it is all not
Become rusty drill rod 3, makes itself and ground rigid contact, to prevent runoff during test from side leakage or structural instability occurs.
A kind of portable test flume measurement soil erosion applied to field rain test described in the utility model influences
The method of the factor is as follows: according to rainfall simulator effective rainfall area, first, using same size and the baffle of quantity in difference
Geomorphic unit encloses the test flume of multiple identical size and shape, miscarry to test vegetation coverage to soil erosion production,
Husky influence；Second, it is identical in same geomorphic unit to enclose multiple size and shape using same size and the baffle of quantity
Test flume produces miscarriage, husky influence to the soil erosion to test rainfall, rainfall intensity and rainfall duration；Third, using phase
The identical test flume of multiple size and shape is enclosed in different gradient region with the baffle of size and quantity, tests the gradient to soil
Earth, which corrodes, produces miscarriage, husky influence；Fourth, the baffle of different number encloses more in identical sloping region using same size
A of same size, the different test flume of length, test length of grade produces miscarriage, husky influence to the soil erosion.It is described in the utility model
A kind of portable test flume applied to field rain test measure Different Soil Insults parameter method: with rainfall simulation
Device combines, first, produce corresponding rainfall factor when flowing according to test flume, determine the raininess-when soil erosion occurs last or
Rainfall-lasts critical value, to carry out forecasting and warning；Second, flowing from the river rising in Ningxia and flowing into central Shaanxi that test flume water outlet is collected, body is measured using graduated cylinder
Product, drying weighing measurement silt, so that it is determined that slope runoff amount and sediment production；Third, area A is gone along with sb. to guard him according to test flume,
Net flow volume V, rainfall Q and ramp slope a calculate runoff coefficient using formula (1).
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
