Horizontal seepage simulation device for rock-soil medium with adjustable sample pool size

Abstract

The invention is widely applicable to the fields of research on the seepage behavior of gas and liquid media in rock-soil media and the research on the migration behavior of solutes in rock-soil media. It is a horizontal seepage simulation device for rock-soil media with adjustable sample pool size. Each is equipped with a sample base; the center of the base fixes the gas or liquid sampling tube in the center of the base through a cock joint; the device has two stainless steel bases at the front and rear; The inside of the body is connected to the gas cylinder through the inlet pipe interface; there is a stainless steel sealing cap at the front and rear ends of the device, the top of which is equipped with a gas or liquid sampling tube, and the inner side of the bottom of the brim is processed with a shaft shoulder matching the first groove. Four sixth threaded holes are evenly carved on the brim of the hat; the sealing cap is set on the periphery of the base and is tightly fixed on the base. The invention is convenient to use and has reliable results.

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
