According to the grouting and water plugging experiment method and device in the dynamic water environment, the experiment sample is subjected to grouting in the dynamic water environment, fracture water gushing caused by fracture of a roadway under the confining pressure condition is simulated, and during grouting and water plugging, the influence of dynamic water on grouting and water plugging can be visually observed. The side coaming is made of tempered glass, the second camera and the third camera are used for recording and shooting the flowing water condition in the side coaming, the first camera is used for recording and shooting the water burst condition at the crack, and the dynamic action rule of slurry and flowing water in the sample can be visually observed. The strain gauge is arranged in the experimental sample, under the action of the hydraulic jack, the strain gauge can detect the change of the pressure borne by the experimental sample, when the experimental sample generates cracks, the moment
