A TPO geomembrane impermeability test device

Abstract

The utility model discloses a kind of TPO geomembrane seepage prevention detection test devices, specifically related to seepage prevention test technical field, including test shell, the outer wall of test shell is equipped with positioning counterweight sealing assembly, positioning counterweight sealing assembly includes: sealing strip, fixedly connected in the lower surface of counterweight frame, sealing strip is used to contact TPO geomembrane surface and adhere to seal;Multiple guide columns, all fixedly connected in the upper surface of counterweight frame, the top of each guide column is fixedly connected with guide end.The utility model uses positioning counterweight sealing assembly, counterweight cover is guided and inserted on the outer wall of guide column along guide end, multiple counterweight cover realize large-area counterweight extrusion to the upper surface of counterweight frame, so that sealing strip and TPO geomembrane surface realize quick contact seal, quickly realize multi-point synchronous counterweight sealing, sealing seepage prevention detection test processing is more efficient.
