Problems solved by technology

[0003] In the existing chemically coupled geotechnical tests, the chemical solution is usually placed directly in the pressure controller. Due to the corrosion of the chemical solution, the controller will be corroded and damaged, which will affect the accuracy of test control and measurement, and improve the test equipment. maintenance cost; while in temperature-coupled geotechnical tests, a single water bath or resistance wire is used to control the temperature in the test, which affects the accuracy of the test temperature control to a certain extent and increases the test cost.
