This equipment is a specialized experimental device used to test the compressive strength of frozen soil under low-temperature conditions. It is mainly used in engineering and scientific research in cold regions to evaluate the mechanical properties of frozen soil under compressive conditions.

Frozen Soil Uniaxial Compression Tester

Model:TGSYE-1

I.Product Functions

This computer-controlled frozen soil testing machine strictly complies with the technical requirements of national industry standards MT/T 593.4-1996"Test Method for Physical and Mechanical Properties of Artificial Frozen Soil-Part 4:Test Method for Uniaxial Compressive Strength of Artificial Frozen Soil"and MT/T 593.6-1996"Test Method for Uniaxial Compression Creep of Artificial Frozen Soil",as well as the international standard ASTM D5520-19"Laboratory Method for Determination of Uniaxial Compression Creep Properties of Frozen Soil Samples".The equipment can simultaneously and accurately measure the test force,axial deformation,and radial deformation of the specimen.The test process is automatically controlled by a microcomputer,which collects and calculates various test data in real time.The system can automatically generate and print test reports,including test data,stress-strain curves,and current test temperature,ensuring efficient,reliable,and complete testing.

The sophisticated automatic control and data acquisition system enables fully digital adjustment of the data acquisition and control process.After the experiment,the computer automatically calculates the results based on the test parameters set at the beginning of the experiment and displays the corresponding test results.Each test parameter can be queried and displayed after the experiment,or it can be printed out by connecting to a printer.
