The invention provides an integral column for soil penetration, dispersion and leaching testing, including a sample column, a chemical solution converter and a pressure-volume controller; the sample column includes a sample column, the top of which is provided with a water inlet, and the bottom of which is provided with a water inlet. There is a water outlet, and a plurality of water outlet holes are opened at different positions of different heights on the side wall. The water outlet and each water outlet hole are provided with a water outlet pipe, the water outlet pipe is provided with a switch, and the end is provided with a solution collector. The top of the body is provided with a compacting structure, and at the same time, a water-permeable structure and a sealing structure are provided at the top and bottom ends of the sample cylinder; the chemical solution converter is provided with a chemical solution, and the pressure-volume controller is used to provide water pressure and apply water pressure. on the chemical solution and injected into the sample cartridge. The invention realizes the monitoring of soil wetting, stable water pressure and evolution law of chemical solution infiltration, dispersion and leaching, and considers the coupling effect of various factors, simulates the complex field environment, and improves the test accuracy.
Description
technical field [0001] The invention relates to the technical fields of geological engineering and geotechnical engineering, in particular to a test integrated column for exploring the penetration, dispersion and leaching characteristics of compacted soil under complex environmental conditions. Background technique [0002] With the development of the global economy and the acceleration of industrialization and urbanization, more and more attention has been paid to geological disasters and environmental issues. Among them, due to domestic waste incineration, mineral mining, metal smelting and large-scale discharge of industrial wastewater, leachate leakage in solid waste disposal, etc., the problem of heavy metal pollution in soil and groundwater has become more and more serious. In recent years, incineration power generation has gradually become an important means of solid waste disposal such as domestic waste. Waste incineration power generation will produce 3%-5% fly ash...
