Abstract
The invention relates to a slope surface runoff sampler and a using method thereof. The sampler comprises a sampler main body, a water guide pipe and a sampling container, wherein two ends of the sampler main body are closed, the sampling container is connected with one end of the sampler main body through the water guide pipe, a screen layer is arranged in the sampler main body, and a sponge layer is arranged between the screen layer and the inner wall of the sampler main body; and the sampler main body is provided with a water inlet. The sampler is embedded into the soil of a vertical slope direction, and the pipe wall of one side of the sampler with the hole faces the slope, so that the sampler can receive the surface runoff water flow flowing down along the slope; and after the water is filtered by a screen and a water absorption sponge, the water enters the sampling container along the water guide pipe and is stored. The sampler can intercept the slope surface runoff, and can filter impurities such as grit, weed, leaves and the like; and meanwhile, the screen of different meshes can be changed as required to filter the impurities of different grain diameters. The sampler for collecting the slope runoff does not affect the water quality, and the intercepted water accords with the measurement requirement of the slope runoff water quality.
