Test device used for field simulation of engineering accumulation body water and soil loss

Abstract

The invention discloses a test device used for field simulation of engineering accumulation body water and soil loss. The test device comprises a cone-shaped accumulation platform and a support frame; the surface of the cone-shaped accumulation platform is provided with ridge shaped projections; the cone-shaped accumulation platform is divided into 2 to 4 accumulation zones; stepped passages are arranged between each pair of adjacent accumulation zones; each accumulation zone is provided with a seepage water collection system and a runoff water collection system; the support frame is arranged on the lower part of the cone-shaped accumulation platform, and is used for supporting the cone-shaped accumulation platform; a test working chamber is formed by the space between the lower part of the cone-shaped accumulation platform and the support frame; the side surface of the support frame is provided with water outlets. The test device is firm in structure, can be used for a plurality of accumulation body water and soil loss tests of same or different substances at the same time, is capable of stimulating field engineering accumulation body on-site environment, and satisfying field long-term observation requirements; the obtained test data is more truthful; foundation data is provided for scientific prevention of disasters such as man-made water and soil loss, and landslide caused by engineering accumulation body; and destroy of engineering accumulation body on the biological environment is eliminated.

Description

technical field [0001] The invention belongs to the technical field of engineering accumulation body tests, and in particular relates to a field simulation engineering accumulation body water and soil loss test device. Background technique [0002] With the rapid development of my country's economy, the number of production and construction projects has gradually increased. As the landform unit with the most serious man-made water and soil loss, the engineering accumulations produced in the production and construction process have attracted widespread attention (Shi Dongmei et al., Engineering accumulations with different soil-rock ratios Runoff erosion process of body slope[J] "Journal of Agricultural Engineering" 2015(17):152-161.). Due to the different soil types and structures, there are still serious safety hazards such as landslides and landslides in the large-scale engineering accumulations formed during the production and construction process. In the existing soil er...
