  • GROUTING AND WATER-PLUGGING DEVICE FOR FRACTURED ROCK IN MINE COUPLING STATE, AND TEST METHOD
    Publication number: 20240085290
    Abstract: The present disclosure provides a grouting and water-plugging device for a fractured rock in a mine coupling state and a test method, and relates to the technical field of rock mechanics testing. The device includes a pressurizer, a reservoir, a test box, and a grouting pump. The reservoir includes a temperature sensor and a pressing-water plate. The pressing-water plate is connected to the pressurizer through a pressurizing rod. A pressure measuring pipe and a drainage pipe are installed on an outer side of the reservoir. The reservoir is connected to a water pump through a water injection pipe. The test box includes a rock, a transverse force exerting plate, a longitudinal force exerting plate, a stress sensor and the temperature sensor. The longitudinal force exerting plate is provided with multiple water through holes. A sliding box door is hinged to a front wall of the test box. The pressure measuring pipe and the drainage pipe are installed on a rear wall of the test box.
