Problems solved by technology

When the geomembrane and anti-seepage mud work together to form a geomembrane composite anti-fouling barrier, the overall performance of the two is particularly important for anti-seepage; when the anti-seepage mud is at the bottom of the pouring trench, the bottom of the geomembrane and the anti-seepage If the mud is not tightly bonded, it will affect the anti-seepage effect of the composite anti-fouling barrier. At present, the anti-seepage performance of the anti-seepage mud can only be evaluated by testing the permeability coefficient of the anti-seepage mud with a penetration instrument. The test results are single, and there is no combination of geomembrane and The overall performance of the anti-seepage mud is evaluated, and there is a lack of reliable methods and devices to evaluate and detect the bonding performance of the geomembrane and the anti-seepage mud at the bottom of the trench

Embodiment Construction

[0038]Below in conjunction with accompanying drawing, the specific technical scheme of the patent of the present invention is further described.

[0039] Such as Figure 1-Figure 3 The shown geomembrane bonding performance test device includes: a support frame, a tension sensor 4, a geomembrane fixture 5, a bottom support 8 for placing a model box, and a model box 13 for fixing the model box on the bottom support The fixing device 7, the bottom support lifting device and the driving device;

[0040] The support frame includes: a fixed pole 1, a vertical column 2 and a crossbeam 14. There are two fixed poles 1 to fix the entire test device on the horizontal ground. The crossbeam 14 is horizontally fixed on the vertical pole 1, and the vertical pole 2 is vertical On the beam 14 and the upper end is fixed at the middle position of the beam, the lower end of the vertical column is fixedly connected to the upper end of the tension sensor 4, and the lower end of the tension sensor ...

Abstract

The invention particularly discloses a device and a method for testing the bonding performance of a geomembrane, which solve the current situation that the impermeable performance of the geomembrane is influenced as no special testing device is used for testing the bonding performance of the geomembrane at present, and the bonding performance between the geomembrane and impermeable slurry is accurately tested by designing the testing device.

Description

technical field [0001] The invention relates to the technical field of geomembrane composite antifouling barrier engineering, in particular to a device and method for testing the bonding performance of geomembrane. Background technique [0002] Pollutants are mostly leaked and diffused through underground channels, and timely enclosing pollution sources and blocking their diffusion channels is one of the most economical and effective pollution control methods. Almost all remediation of leaked landfills requires the construction of vertical isolation barriers to form a complete enclosure system. The vertical barrier is based on the site conditions, using the common impermeable layer and relatively independent hydrogeological units under the site, and selecting materials with good anti-seepage and sewage interception performance around the polluted area to form a vertical wall to prevent leachate from entering the underground environment , and finally achieve the effect of co...
