Rock-soil medium horizontal seepage simulation device with adjustable size of sample pool

Abstract

The method is widely applied to the fields of research of seepage behaviors of gas and liquid media in a rock-soil medium, research of migration behaviors of solutes in a rock-soil medium, and the like, and discloses a rock-soil medium horizontal seepage simulation device with an adjustable size of a sample pool; sample bases are arranged at the two ends of the device respectively, wherein a gas or liquid sample inlet pipe is fixed in each base center through a rotary plug connector; the device comprises a front stainless steel base and a rear stainless steel base; a gas inlet pipe connector is arranged near the center of the base; the interior of a barrel body is connected with a gas steel cylinder through the gas inlet pipe connector; a stainless steel sealing cap is arranged at each ofthe front and rear ends of the device separately, and a gas or liquid sample inlet pipe is arranged at the top of the device; a shaft shoulder matched with a first groove is machined on the inner sideof the bottom of each cap brim, and four sixth threaded holes are uniformly engraved in the cap brim; and the sealing caps are arranged on the periphery of the base in a sleeving mode and are tightlyfixed on the base. The rock-soil medium horizontal seepage simulation device is convenient to use and reliable in result.

Description

technical field [0001] The invention relates to a rock-soil medium horizontal seepage simulation device with an adjustable sample pool size, which is widely used in the fields of research on the seepage behavior of gas and liquid media in rock-soil media, the migration behavior of solutes in rock-soil media, and the like. Background technique [0002] Seepage of gas and liquid in rock and soil media is a common phenomenon in nature. In addition, usually the solute in the solution will also migrate in the rock and soil with the seepage of the liquid. Therefore, both the seepage in rock-soil media and the migration of solutes in rock-soil media are basic research topics that people generally pay attention to. Many researchers hope to clarify the seepage mechanism and solute migration mechanism in rock-soil media through experimental simulation, so as to control the seepage behavior and solute migration behavior in rock-soil media, and better meet people's production and livin...

Problems solved by technology

It can be seen that when using this device, the influence of gravity itself on the experimental process cannot be ignored, which increases the uncertainty of the experimental results.

On the other hand, for the flexible wall permeameter, in order to ensure the smooth progress of the experiment, it is required to ensure that the two sections of the sample are neat when making the rock-soil medium sample, so that the two ends of the rock-soil sample and the upper and lower ends of the permeameter The sampling port and the outflow The ports are tightly fitted, so the requirements for the production of rock and soil samples are relatively high, especially for rock and soil samples with high hardness such as granite, it is difficult to process in the laboratory
