It is a kind of flexible polymer chemical material with low specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance. During the production process, equipment is often required to test the tensile strength of the geomembrane.

[0003] Chinese patent CN222618391U proposes a geotextile testing device that is easy to maintain. It uses a bidirectional screw to drive a stop plate closer to a rotating roller, thereby clamping and fixing the geomembrane. Then, by rotating the roller, the geomembrane is pulled and rotated for testing. However, this design requires manual rotation of the roller, resulting in inaccurate testing and making geomembrane fixing difficult and inconvenient. There is an urgent need for a geotextile testing device that is easy to maintain to solve these problems. Utility Model Content
