The invention relates to a soft foundation treatment construction device, and belongs to the technical field of soft foundation treatment construction. Comprising a stirring drill bit, a drill rod and a water connector, a bevel gear for inserting a core tube is arranged in the stirring drill bit, a bevel gear is arranged at one end of a stirring shaft and meshed with the bevel gear in the stirring drill bit, and a stop device and a speed change device are arranged in the water connector. The device has the beneficial effects that the speed change device enables the core tube and the drill rod to rotate reversely, and the core tube in the stirring drill bit is meshed with the horizontal stirring shaft with the bevel gear through the bevel gear, so that the stirring blades on the stirring shaft are driven to rotate in the vertical direction and act together with horizontal stirring of the stirring blades on the stirring drill bit; and in addition, the gas pipe attached in the drill rod pumps high-pressure gas i
