Abstract

The invention discloses an unsaturated triaxial apparatus,, which comprises an outer cylinder, a pressure cylinder, a main cover plate, a sample base, an auxiliary cover plate and a loading rod, wherein the pressure cylinder is arranged in the outer cylinder and is internally provided with a pressure cavity with an upper opening, and the peripheral wall of the pressure cylinder and the inner wallof the outer cylinder form a water bath cavity with an upper opening; and the upper end of the loading rod penetrates through the through hole and is fixedly connected with the auxiliary cover plate,and a sample cap and a hooking structure capable of hooking the sample base and driving the sample base to be separated from the pressure cavity are arranged at the bottom of the loading rod. Throughthe split design of the main cover plate and the auxiliary cover plate, when a sample is taken and placed, only the auxiliary cover plate needs to be opened, and arrangement of the water bath cavity and pipeline interference are not influenced. Besides, when the sample needs to be taken out, only the auxiliary cover plate needs to be detached, the auxiliary cover plate drives the loading rod, thesample base, the sample cap and the sample between the sample base and the sample cap to be taken out of the pressure cavity together, various operations do not need to be carried out in the narrow pressure cavity, 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 ...
