Problems solved by technology

[0008] (1) The system does not consider both rainfall infiltration and in-situ leaching liquid injection, so it is impossible to carry out simulation experiments on the coupling seepage behavior of rainfall infiltration and in-situ leaching water return;
[0009] (2) When rainfall infiltration is not considered, the influence of preferential flow due to liquid injection holes and natural macropores on water transport
[0010] (3) When rainfall occurs, the control of the boundary water level cannot be realized, and it is necessary to accurately obtain the position of the in-situ leaching liquid level, that is, the groundwater level. The existing simulation system
[0011] (4) The simulation functions of pollutant migration simulation and slope moisture and pore water pressure transmission cannot be satisfied at the same time

Abstract

The invention discloses a rare earth slope preferential flow simulation test system, and relates to a laboratory permeation experiment device. The rare earth slope preferential flow simulation test system integrates a rainfall system, a water supply system, a monitoring system, a soil bin permeation device and a boundary water level control water tank. The test system comprises a soil tank and is characterized by further comprising the rainfall system and the water supply system which are arranged on the upper portion of the soil tank, the moisture and pore water pressure monitoring system arranged in the soil tank and the boundary water level control system arranged on the two sides of the soil tank.

Description

technical field [0001] The invention belongs to the technical field of slope infiltration tests, and specifically relates to the development of preferential flow infiltration simulation test equipment under the joint action of ionic rare earth slope in-situ leaching and rainfall infiltration. Background technique [0002] In order to study the pollutant migration and landslide disasters that may be caused by the in-situ leaching process of ionic rare earths in the south, the laboratory physical simulation test research method is one of the commonly used research methods. A set of scientific and reasonable model test system is the key to carry out similar research. At present, whether it is pollutant migration, or landslide mechanism or process simulation, the indoor soil tank simulation system is one of the most important test devices. [0003] In the process of in-situ leaching of rare earths, in order to reduce the probability of landslides, the leaching liquid injection ...
