Summary:The utility model discloses a grouting plugging assembly based on well plugging. The grouting plugging assembly comprises a pressure-bearing well body, a structural bottom plate and a grouting pipe. The device has the advantages that during plugging, firstly, high-quality clay is injected into the filter pipe through the grouting pipe, high-quality clay slurry enters the periphery of the dewatering well through the filter pipe, gaps of the filter pipe are plugged, the water insulation effect in the pipe is improved, micro-expansive concrete is injected into the filter pipe through the grouting pipe, and the water insulation effect in the dewatering well is improved. The micro-expansive concrete is sealed to the bottom of the structural bottom plate and is flush with the bottom of the structural bottom plate, the micro-expansive concrete can be matched with high-quality clay, the water insulation effect in the pipe is improved, the problem that confined water flows along the outer wall of the confined water we
