Abstract

The invention provides a movable slope-varying-type steel trough for simulating soil leakage status in karst regions. The movable slope-varying-type steel trough includes a trough body, in which a vegetation simulating layer, a soil simulating layer, a rock simulating layer and a water and soil collecting layer are disposed successively from top to bottom. Steel bars or an iron wire net is arranged on the lower end of the rock simulating layer and is used for supporting and fixing the rock simulating layer. The water and soil collecting layer is a hollow layer which is disposed between the rock simulating layer and the bottom of the trough body. A soil surface collection trough and a soil leakage collection through are disposed on one side of the trough body and an elevating device is arranged on the other opposite side of the trough body and is used for lifting the trough body. The movable slope-varying-type steel trough aims to solve the problem that soil erosion researching in karst regions only focuses on the erosion process on earth surface and researching and simulation on soil leakage is still in a blank stage. The invention belongs to the field of researching and simulation of water and soil in the karst regions.

Description

technical field [0001] The invention relates to a slope-changing experimental tank, which belongs to the field of soil leakage research in karst areas. Background technique [0002] The complex and unevenly distributed double pore structure of the surface and underground media formed under karst action leads to soil leakage in addition to surface loss, which is related to the development of karst fissures caused by the vertical action of groundwater. The lost soil is eroded, transported, and accumulated through underground passages, which is fundamentally different from the soil erosion characteristics in other non-karst areas. Previous soil erosion focused on the erosion process with the surface. There are few studies on the underground loss of karst soil. The simulation of soil underground leakage is a blank at home and abroad. Contents of the invention [0003] The purpose of the present invention is to provide a mobile variable-slope experimental tank for simulating s...
