Settlement treatment grouting device for high fill construction foundation

The invention discloses a settlement treatment grouting device for a high-fill construction foundation, and relates to the technical field of grouting devices for construction foundations, the settlement treatment grouting device for the high-fill construction foundation comprises an outer fixing frame, and the top of the outer fixing frame is fixedly connected with a power mechanism. A motor body is fixed outside a driving shaft, the motor body is started to enable the driving shaft to rotate, a driven wheel drives an inner driving vertical pipe to rotate, a high-pressure water pipe and an excavation toothed plate are installed at the bottom of the inner driving vertical pipe, and when the inner driving vertical pipe rotates downwards, the excavation toothed plate excavates a high-fill foundation. Impact of a high-pressure water gun is carried out while excavation is carried out, so that water seepage is further carried out on the high-fill foundation, further sedimentation of a grouting part is facilitated,
