Technical Field

[0002] Geomembrane is a seepage-proof material used in soil engineering. It is usually made of high molecular polymers and is widely used in civil engineering, water conservancy engineering, environmental engineering, and agricultural engineering. For example, it can be used for reservoirs, dams, tunnels, landfills, and seepage prevention ponds. It can play a role in seepage prevention, isolation, protection, and reinforcement, and improve the stability and reliability of the project. To evaluate the corrosion resistance of geomembranes and to provide important reference and basis for geomembrane processing and application, a corrosion resistance testing device for geomembrane processing is needed.

[0034] Combination Figure 1-3A cylinder 6 is fixedly connected to the top of the testing box 1. A connecting plate 7 is fixedly connected to the output end of the cylinder 6. The channel start cylinder 6 pushes the connecting plate 7 downward. A uniformly distributed fixing cover 8 is fixedly connected to the bottom of the connecting plate 7. The fixing cover 8 is used to fix the geomembrane slice. An infusion assembly is set on the top of the fixing cover 8. The infusion assembly includes an infusion tube 9, which passes through the fixing cover 8 and is fixedly connected. The infusion tube 9 passes through the connecting plate 7 and is fixedly connected. A telescopic tube 10 is fixedly connected to the inner wall of the infusion tube 9, which passes through the testing box 1 and is fixedly connected. Corrosive liquid is delivered to the surface of the geomembrane slice through the infusion tube 9 and the telescopic tube 10. A sealing cap 11 is threaded through and threaded to the top of the telescopic tube 10. The sealing cap 11 is used to seal the opening of the telescopic tube 10 exposed outside the testing box 1. A uniformly distributed placement groove 12 is set through and set on the top of the placement platform 2. The placement groove 12 is slidably connected to the fixing cover 8. The placement groove 12 is used to place the geomembrane slice.
[0035] Combination Figure 1-4 An electric push rod 3 is fixedly connected to the rear end of the testing box 1, and the output end of the electric push rod 3 is fixedly connected to the placement platform 2. When the electric push rod 3 is activated, it pushes the placement platform 2 out of the testing box 1. Slider 4 is fixedly connected to both sides of the placement platform 2. Slide grooves 5 are provided through both sides of the inner wall of the testing box 1, and the slider 4 is slidably connected to the slide grooves 5 to guide the placement platform 2 out of the testing box 1.

[0036] Working principle: When conducting geomembrane corrosion resistance testing, the sampled and cut geomembrane is placed inside the placement trough 12. At this time, the cylinder 6 is activated to push the connecting plate 7 downward until the fixing cover 8 fixes the geomembrane slice. Then, the sealing cover 11 is unscrewed, and different corrosive liquids are introduced into the infusion pipe 9 through the telescopic pipe 10. The infusion pipe 9 then delivers the corrosive liquid to the surface of the geomembrane slice, so that the corrosive liquid is evenly distributed on the surface of the geomembrane. If the corroded geomembrane forms a perforation, the corrosive liquid will enter the placement platform 2 through the through hole 13 on the placement trough 12. After the testing is completed, the cylinder 6 is activated again to pull back the fixing cover 8. Then, the electric push rod 3 is activated to push the placement platform 2 out of the testing box 1. The sampled and cut geomembrane is observed. Then, the valve 15 is opened, and the corrosive liquid inside the placement platform 2 is discharged through the drain pipe 14.
