Problems solved by technology

In the anti-seepage of geomembrane storage plate, the gas in the unsaturated soil under the membrane can cause the membrane body to expand and destroy, resulting in water leakage from the reservoir and affecting the normal operation of the reservoir.
[0003] Therefore, it is of grea

Embodiment Construction

[0011] exist figure 1 Among them, this kind of geomembrane inflation test device includes an above-membrane equipment container 2 with a top cover 3 and an under-membrane equipment container 4 with a base 5, the two are connected and have a through passage.

[0012] The above-membrane equipment container 2 is composed of a cylindrical container body, a top cover 3 and its accessories. The material is made of steel, plexiglass or other hard materials. The accessories mainly refer to the first flange 7 and the second flange 8. Connect the first pipe valve interface 9 of the test equipment, the second pipe valve interface 10 connected to the test water source supply device, etc., the first flange 7 and the second flange 8 are respectively solidly welded on the cylinder of the equipment container 2 on the membrane At both ends of the cylindrical container body, the top cover 3 is connected with the first flange 7 for sealing the container body or filling the medium. The above-mem...

Abstract

The invention discloses a geomembrane gas inflation test device, belonging to the field of hydraulic engineering. The geomembrane gas inflation test device comprises an on-geomembrane equipment container and a below-geomembrane equipment container communicated with the on-geomembrane equipment container, wherein a geomembrane body material to be tested is located between the on-geomembrane equipment container and the below-geomembrane equipment container and used for separating a channel, the on-geomembrane equipment container internally stores upper media for simulating an on-geomembrane environment, the below-geomembrane equipment container is filled with lower media for simulating a below-geomembrane environment, and the bottom of the on-geomembrane equipment container is provided witha first pipe valve interface communicated with a testing system and a second pipe valve interface communicated with a test water source supply device; the bottom of the below-geomembrane equipment container is provided with a third pipe valve interface communicated with the testing system and a fourth pipe valve interface communicated with a drainage system; and a top cover is provided with an air exhaust or water drainage valve. The geomembrane gas inflation test device can be used for conveniently carrying out a membrane material gas inflation destructive test, a membrane material air permeability test and penetration tests before and after membrane material gas inflation destruction.

Description

technical field [0001] The invention relates to a test device used in a horizontal film-laying anti-seepage project in the field of hydraulic engineering, in particular to a geomembrane inflation test device. Background technique [0002] In order to solve the problem of no regulation and storage reservoirs in some plain areas, my country needs to build a large number of plain reservoir regulation and storage projects. In the construction of plain reservoirs, reservoir seepage control is a key technical issue in the construction of plain reservoirs. In the anti-seepage design of plain reservoirs, for plain reservoirs with poor geological conditions and lack of ideal impermeable layers, it is necessary to consider the anti-seepage scheme of the storage plate, that is, the overall horizontal anti-seepage of the bottom of the reservoir. Considering economic factors, geomembrane anti-seepage is the first choice in the anti-seepage of the library plate. In the anti-seepage of g...
