Deep high-water-pressure double-fracture grouting simulation test device

The invention discloses a deep high-water-pressure double-crack grouting simulation test device which comprises a slurry supply system, a double-crack grouting model set, an automatic pressure monitoring system and a hydrostatic pressure control system. The fluid outlet end of the slurry supply system is in fluid communication with the fluid inlet end of the double-crack grouting model set, and the detection end of the automatic pressure monitoring system makes contact with slurry flowing on the double-crack grouting model set. The control signal output end of the automatic pressure monitoring system is electrically connected with the control signal input end of the hydrostatic pressure control system; the fluid outlet end of the double-fracture grouting model set is in fluid communication with the fluid inlet end of the hydrostatic pressure control system. According to the invention, the research on the slurry diffusion rule between independent fractures with different opening degrees in the grouting environ
