Laminated concrete impermeability testing machine

The utility model discloses a laminated concrete impermeability testing machine which comprises a frame placed on the ground, supporting plates are fixedly installed on the two sides of the frame at equal intervals, linear guide rails are fixedly installed on the surfaces of the supporting plates, and trays are installed on the supporting plates through the linear guide rails. A pressurizing unit fixing frame is in lap joint with the surface of the tray, and a pressurizing unit is arranged on the surface of the pressurizing unit fixing frame. According to the laminated concrete impermeability testing machine, the framework, the supporting plates and the linear guide rails are arranged in a matched mode, so that the pressurizing unit fixing framework is placed in a portal three-dimensional drawer type stacking mode, the occupied area is further reduced, and when the pressurizing unit is carried to a press machine or a hydraulic demolding device for follow-up test detection, the labor intensity of workers is re
