Geotechnical cloth water permeability testing device

The utility model discloses a geotextile water permeability testing device which comprises a box body, supporting columns are fixedly connected to the two sides of the top of the box body, an upper cover plate is fixedly connected to the tops of the supporting columns, and a shell is fixedly connected to one side of each supporting column. The motor drives the driven gear and the threaded rod to rotate under the cooperation of the rotating rod and the main gear, the threaded rod drives the threaded sleeve to move downwards, the threaded sleeve drives the pressing plate to move downwards under the cooperation of the connecting rod, and when the pressing plate moves to the designated position, the purpose of pressing geotextile is achieved; the problems that an existing testing device is low in automation degree and needs to be manually operated through an external tool, so that the purpose of clamping the hydraulic fabric is achieved, time and labor are wasted, the working strength is improved, meanwhile, the
