Geomembrane creep property testing device

The utility model discloses a geomembrane creep property testing device. The device comprises a geomembrane tension applying mechanism, a displacement sensor, a tension sensor and a main console, thegeomembrane tension applying mechanism comprises a rack, a center pull rod, a pull rod driving mechanism and a telescopic cantilever connected to one end of the rack. A center pull rod is arranged inthe telescopic cantilever in the axis direction of the telescopic cantilever in a penetrating mode, one end of the center pull rod is located in the rack, and the other end of the center pull rod extends out of the telescopic cantilever and is fixedly connected with the geomembrane clamp through a locking mechanism. The pull rod driving mechanism is used for driving the central pull rod to move back and forth along the telescopic direction of the telescopic cantilever; the tension sensor is used for detecting the tension value of the test geomembrane in real time; the displacement sensor is used for detecting the linea
