Background

The triaxial test is one of the most common test methods in the soil test in the laboratory, and in the triaxial test, the B value is an index for measuring the saturation of an experimental sample, and the lower the saturation is, the more the gas in water is, and the larger the error of the experimental result is. According to the Standard of the test method for the Chinese geotechnical engineering (GB/T50123-2019), the B value of the triaxial test needs to reach 0.98, which means that the air content in the saturated sample is very low, so that the data result meets the requirement of high accuracy.

Referring to fig. 1, the heating water container suitable for triaxial experiment in the embodiment of the present invention includes a water container 10, a heater 20 and an experiment container 50, the heater 20 is used for heating the liquid in the water container 10, and after the liquid in the water container 10 is heated, a large amount of dissolved gas in the liquid escapes from the liquid, so that the gas content of the liquid is low. The experiment container 50 is used for placing the experiment sample 40, and the heated liquid in the water container 10 flows into the experiment container 50, so that the subsequent triaxial experiment can be carried out, and the success rate of the experiment is improved. Alternatively, the liquid in the water container 10 may be distilled water or other liquid that does not affect the properties of the test sample 40, and distilled water is selected in this embodiment.
