Embodiment 1

[0020] Such as Figure 1~3 The shown portable test tank for field rainfall test aims to provide a test tank that can be easily disassembled, installed and carried, and the size of the space range can be adjusted at the same time. According to the above requirements, the test tank is composed of several baffles 1 and an end cover 4, the specific structure, principle and usage method are as follows.

[0021] Such as figure 1 As shown, the scope of the test tank is limited by the baffle 1, and the end surface of the baffle 1 is provided with a plug 2. At the same time, a fixing hole structure is provided on the connector plug 2 . When in use, the two adjacent baffle plates 1 are relatively stable by inserting the stainless steel brazing 3 into the fixing hole of the connector plug 2 . The material of the baffle 1 is stainless steel, which can be detached and combined arbitrarily through the stainless steel braze 3, thereby forming test spaces of different sizes or shapes.

Abstract

The invention relates to a portable test trough applied to field rainfall test and a test method. The portable test trough applied to field rainfall test comprises a plurality of baffles and an end cap, wherein connecting plugs and fixing hole structures are separately arranged at the edges of the baffles and the end cap, stainless steel rods are inserted in fixing holes, thus, the baffles keep stable relatively, the baffles and the end cap also keep stable relatively, and a water outlet is formed in the bottom end of a trough body. The portable test trough applied to field rainfall test has the beneficial effects that test spaces in different sizes are formed in a surrounding manner by increasing and reducing the number of the baffles, therefore, various test regions in different sizes orshapes are formed, the shortcoming of form simplification of a traditional device is overcome, the problem of poor structural stability is further solved, the portable test trough has the advantagesof easiness in mounting, convenience in carrying and the like, and the portable test trough is combined to a rainfall simulator, not only can be used for analyzing influences of factors such as vegetation coverage, rainfall factors and terrain to soil erosion, but also can be used for measuring parameters such as different types of soil runoff coefficients, slope runoff volume, erosion and sediment yield and runoff producing critical rainfall threshold values.

Description

technical field [0001] The invention relates to a portable test tank and a test method for field rainfall tests, belonging to the field of soil erosion experiments. Background technique [0002] Geological disasters and soil erosion caused by rainfall are one of the main ecological and environmental problems facing our country, posing a serious threat to human production and life. In order to effectively prevent disasters, it is very necessary to carry out all-round small-scale field test research on soil erosion process, influencing factors and characteristics, so as to obtain more realistic and suitable data for actual characteristics. At present, scholars at home and abroad have carried out a large number of soil erosion tests through rainfall simulation tests. However, the existing traditional devices are mainly suitable for indoor simulated rainfall tests, and generally have a fixed shape and size, and cannot adjust the size of the test area arbitrarily. Therefore, it ...
