Abstract

The invention discloses an unsaturated triaxial instrument, which comprises an outer cylinder, a pressure cylinder, a main cover plate, a sample base, a secondary cover plate and a loading rod; the pressure cylinder is installed in the outer cylinder, and has a pressure chamber with an upper opening inside , the outer peripheral wall of the pressure cylinder and the inner wall of the outer cylinder form a water bath chamber with an upper opening; the upper end of the loading rod passes through the perforation and is connected with the auxiliary cover plate, and the bottom of the loading rod is provided with a sample cap and a base that can hook the sample and drive the sample Hook structure for detaching the base from the pressure chamber. The present invention adopts the split design of the main cover and the auxiliary cover, so that when taking and placing samples, only the auxiliary cover needs to be opened, without affecting the arrangement of the water bath cavity and the interference of pipelines; in addition, when it is necessary to take out the sample, only the auxiliary The cover plate is disassembled, and the sub-cover plate is taken out of the pressure chamber together with the loading rod, the sample base and the sample cap, and the sample between the sample base and the sample cap. Various operations are carried out inside, and the sample is convenient to take and place.

Description

technical field [0001] The invention relates to a measuring and testing instrument, in particular to an unsaturated triaxial instrument. Background technique [0002] The physical and mechanical properties of natural soil will vary greatly with the moisture and temperature conditions. In thermal energy storage, geothermal resource development, nuclear waste treatment, oil extraction, heating pipeline design, high-voltage cable embedding and other projects, temperature changes have a great influence on the engineering properties of soil. Therefore, it is often necessary to use a triaxial instrument to study and test the soil quality. [0003] Usually, the sample is put into the pressure chamber and wrapped by a rubber film, which is limited by the space of the pressure chamber and the interference of the sample cap, which makes it quite troublesome to take and place the sample in the pressure chamber. Contents of the invention [0004] The present invention aims to solve ...
