Abstract

The invention discloses a chemical solution saturation device for polluted soil and its application method. The device is composed of a holding device, a vacuum device and a liquid adding device. The holding device includes a holding rack, a sample holding dish, a holding dish cover and a saturator. The vacuum device includes a vacuum pump, a first decontamination box, an air conduit, and a vacuum valve, and the liquid adding device includes a pressurization pump, a pressurization conduit, a pressurization switch, a second decontamination box, a solution conduit, a solution box, and a solution switch. The present invention adopts several small holding dishes, one sample is placed in each holding dish, and each holding dish corresponds to a solution box, so that the one-time saturation of samples with different chemical solution concentrations can be realized. The method of inflow from the top and bottom of the sample effectively avoids the phenomenon of air bubbles during the inflow of the solution. The container conduits involved in the present invention are all made of corrosion-resistant materials, and a decontamination device is added, which effectively avoids the impact of the chemical solution on the sample. Corrosion of installations and related equipment.

Description

technical field [0001] The invention relates to a chemical solution saturation device for polluted soil and an application method thereof, belonging to the field of civil engineering rock soil testing. Background technique [0002] As a key resource for human survival, soil plays an important role in human life and production activities. In recent years, with the rapid development of the economy, the situation of soil pollution in my country is very serious. The underground soil layers of most industrial factories, obsolete landfills, and sludge dumps are eroded and damaged by chemical pollutants to varying degrees, and the structure of the contaminated soil will change, thereby affecting its mechanical properties. Therefore, it is necessary to carry out relevant research on the mechanical properties of chemically polluted soil. [0003] In order to study the mechanical properties of contaminated soils below rainfall, valley terraces and groundwater levels, saturated soil ...
