Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-pressure seepage test device, which solves the problem that the currently used seepage test device usually uses natural pressure to carry out seepage. When the pressure needs to be changed, it can only be pressurized by increasing the weight, and the pressure is limited. , unable to meet the needs of higher pressure use

Abstract

The invention discloses a high-pressure seepage test device, which specifically includes: a seepage cylinder, the inner wall of the seepage cylinder is fixedly connected with a storage cylinder, the top and bottom of the storage cylinder are equipped with fine metal mesh, and the inside of the storage cylinder is filled with There is a seepage medium, and the part of the seepage cylinder below the material storage cylinder is connected with an outlet pipe; the pressure cylinder is arranged on the top of the seepage cylinder and communicates with the seepage cylinder, and the inner wall of the pressure cylinder is slidably connected with a A pressurized piston, the pressurized piston is connected with external hydraulic equipment, and a water injection device is arranged inside the pressurized piston; an overflow device, the overflow device is arranged on the top side of the seepage cylinder. The present invention relates to the field of seepage technology. This high-pressure seepage test device is convenient to adjust the pressure during seepage, and can make the seepage pressure exceed the natural gravity of the water inside the device, which is convenient to adapt to different use needs during the test, and can freely control the size of the natural pressure during the test. The adjustment operation is simple .

Description

Technical field [0001] The present invention relates to the field of seepage techniques, in particular a high pressure seepage test device. Background technique [0002] The seepage flow is a flow of fluid in the pore medium, consisting of a particulate or crushed material, and contains a plurality of pores or fractures referred to as a pore medium, typically, the seepage in the soil or rock formation below the ground surface is called ground water movement. It is the most common seepage phenomenon in nature, seepage in the fields of water conservancy, geology, mining, oil, environmental protection, chemical, biological, medical, etc. Pit drainages, etc. need to be applied to seepage theory. The current use of the seepage experimental device typically performs seepage through natural pressure. When changing the pressure, it can only be pressurized by increasing the weight, the pressure is limited, and the need for higher voltage cannot be adapted. Inventive content [0003] (1) ...
