[0002] In soft soil foundation treatment projects, in order to improve the strength and stability of soft soil, it is usually necessary to fully mix the soft soil curing agent with the soft soil. Traditional treatment methods often have problems such as uneven mixing and low treatment efficiency. Some equipment only has a single stirring function or spraying function, which cannot achieve the coordinated operation of stirring and spraying, and cannot meet the requirements of spraying the curing agent with a suitable content according to the stirring frequency, which is difficult to meet the treatment requirements under complex soft soil geological conditions.
