Zusammenfassung: | The invention relates to a deep rock mass creep impact test device capable of simulating impact disturbance. A rack body is fixedly mounted on a base; an upper piston and a lower piston are mounted ina hydraulic oil cylinder; hydraulic oil is filled between the upper piston and the lower piston; a pressurizing plate is fixedly mounted at the lower end of a pressurizing rod; a pressure sensor is mounted in a screw hole; the lower end of a pull rope type displacement sensor is connected to a circular ring on the surface of a test table through a lifting rope along the vertical direction; the upper outlet of an air tank penetrating the test table through an impact slideway is in contact connection to the bottom of a pressure bearing base plate; a display is arranged on a control cabinet; anelectromagnetic valve is mounted on the side face of the lower part of the impact slideway, and an impact rod is arranged in the impact slideway; and the pressure sensor, an air compressor and the electromagnetic valve are con |
