The utility model discloses a
geomembrane anti-puncture performance detection device in the technical field of geomembranes. The
geomembrane anti-puncture performance detection device comprises a supporting plate, a
rotating disc, a driving cylinder, a lifting seat, a
pressure sensor, a puncture rod, a first positioning mechanism, a rotating ring, a supporting ring, a plurality of supporting rods, a plurality of clamping mechanisms and a second positioning mechanism. Free adjustment of three-dimensional angles is achieved through the
rotating disc and the driving cylinder, so that the multi-direction puncture
test requirements are met, the puncture working conditions of landforms such as slopes and curved surfaces can be accurately simulated, and the working condition coverage rate is increased; the angle is locked after adjustment through the first positioning mechanism and the second positioning mechanism, so that the test stability is ensured; the puncture force is monitored in real time through the
pressure sensor, so that dynamic acquisition of data is realized, and the
measurement precision is ensured; and finally, through a plurality of uniformly distributed clamping mechanisms, the sample is uniformly stressed during testing, so that the testing stability is improved.
