Rapid plugging method for pipe inrush inlet based on hydrated granular material

The invention belongs to the technical field of dam flood prevention and emergency reinforcement, and discloses a hydrated particle material-based rapid plugging method for a pipe inrush inlet, which comprises the following steps: S1, selecting hydrated particles; s2, determining a material throwing mode; s3, determining the laying area: selecting and determining the laying area according to different leakage parts of the piping slope; s4, the laying thickness is determined, wherein the thickness of the hydrated particle layer is determined by the thickness Tb of the biological disturbance layer, the anti-seepage thickness Tk and the upper limit thickness Tmax; s5, plugging of a pipe inrush inlet: S5.1, building a floating platform; s5.2, a gravel filling layer is thrown at a leakage inlet of the leakage part; s5.3, a hydrated particle layer is laid according to the preset area in the S2 and the preset height in the S3; s5.4, after the hydrated particle layer is thrown, whether the laying thickness meets the
