A water replenishment tank 36 and a curing agent tank 37 are fixed on the batching rack 35.

The water replenishment tank 36 is used to adjust the water content of the mud, and the curing agent tank 37 is used to add the curing agent. The two work together to make the mud achieve a suitable fluid state and curing effect. The continuous stirring of the spiral stirring shaft 34 ensures that the mud, water and curing agent are fully mixed to form a uniform fluidized solidified soil. The mixed fluidized solidified soil is discharged through the discharge pipe on the lower surface of the mixing frame 31, and then the mixed fluidized solidified soil is transported to the construction site for filling by the filling pump.
