Problems solved by technology

[0004] The present invention designs a rain shielding device for artificially simulating rainfall tests with different slope lengths on the same soil tank. The technical problem it solves is in the research on the response mechanism of different slope lengths to flow generation and confluence in the existing artificial rainfall simulation process. , often use different soil tank fills to realize the research of different slope lengths, but this method needs to spend more manpower and material resources in the test process

Embodiment Construction

[0020] Combine below figure 1 , the present invention is further described:

[0021] Such as figure 1 As shown, a rain shield device for artificially simulating rainfall tests with different slope lengths on the same soil tank includes a rain shield 1 and a soil tank 5 with an inclined angle. The soil tank 5 is filled with soil, and the rain shield 1 covers Above the soil and extending out of the soil tank 5. The rain shield 1 is a plurality of blocks, and the plurality of rain shields 1 are connected end to end to form a whole so as to cover and control the soil with different slope lengths.

[0022] The two ends of each rain shield 1 facing away from the soil are respectively provided with a front inverted V-shaped structure connecting plate 2 and a rear end baffle 4, and a rain shield rear end is passed between two adjacent rain shields 1 Plate 4 is stuck in the V-shaped structure of the inverted V-shaped structure connecting plate 2 at the front end of another rain shie...

Abstract

The invention relates to a flashing board device for performing artificially simulated rainfall tests of different slope lengths on the same soil bin. The flashing board device comprises flashing boards (1) and the soil bin (5) having an inclined angle. The soil bin (5) is internally filled with soil. The flashing boards (1) cover above soil and extend to the outside of the soil bin (5). The flashing board device is characterized in that there are plural flashing boards (1), and the plural flashing boards (1) are connected into a whole in an end-to-end way so as to realize coverage and control of soil of different slope lengths. The flashing board device can be used for the indoor or outdoor artificially simulated rainfall tests to research the response mechanism of different slope lengths, gradients, rainfall intensity and soil moisture content on runoff.

Description

technical field [0001] The invention relates to the field of hydrology research, in particular to a rain shield device for artificially simulating rainfall tests with different slope lengths on the same soil tank, which can be used for artificially simulating rainfall with different slopes, slope lengths, rain intensity, and soil water content Research on the mechanism of the rate-to-runoff response. Background technique [0002] The study of rainfall-runoff response relationship is an important way to understand the hydrological process of a watershed. Soil water is one of the important hydrological variables, and it is a key factor affecting the dynamic process of hydrology at different spatial scales, such as flooding, erosion, and solute transport in soil. The study of rainfall and runoff law of different soil slope lengths is also one of the hotspots of hydrology research in recent years. [0003] In the current research work, there are many methods for artificially s...
