Problems solved by technology
[0003] In order to solve the time-consuming immersion of rock mechanics experiment samples in the prior art, when encountering liquids with high viscosity, density, and liquid surface tension, it is difficult for the solution to immerse into the sample, and the long time will cause the solution to solidify and obtain different saturation. Due to the difficulty of immersing samples with high density, the present invention provides a rapid immersion device and method for rock mechanics experiment specimens

A rock mechanics experiment test piece rapid immersion device comprises an experiment container, the experiment container comprises an upper shell and a lower shell, a piston is arranged in the upper shell, and a test piece fixing device is arranged in the lower shell; an exhaust valve, a liquid injection valve and a hydraulic pressure gauge are arranged outside the lower shell; a hydraulic valve is arranged outside the upper shell. During operation, the time of injecting a solution into a sample is shortened, the time is saved for a rock mechanics sample experiment, liquids with different viscosities and concentrations can be effectively injected into the sample, the sample is prevented from being damaged, and therefore, rock mechanics samples with different saturations can be easily obtained.
Description
technical field [0001] The invention relates to the technical field of rock mechanics experiments, in particular to a rapid liquid immersion device and method for rock mechanics experiment specimens. Background technique [0002] Rock mechanics sample immersion (liquid) test means that the sample is put into the solution to allow the sample to reach different saturations. It includes sample immersion in water, sample immersion in cement mortar, etc. During the sample immersion process, often Immersion under natural pressure takes a long time. When the sample is immersed in the liquid with high viscosity or density, the surface tension of the liquid is high, and the solution will be difficult to immerse into the sample. If the immersion time is too long, the solution will solidify. Contents of the invention [0003] In order to solve the time-consuming immersion of rock mechanics experiment samples in the prior art, when encountering liquids with high viscosity, density, an...
