590121 Disclosed is a device for consolidating soils by means of mechanical mixing and injection of consolidating fluids, designed to be connected to one or more drilling rods and to carry out operations of drilling and mixing. The device comprises a main body, one or more blades, mobile with respect to said body, constrained by means of cams to a central structure internal to said body; the device further comprising means for the flow of fluids, connected in a liquid-tight way to at least one sprayer. A relative motion is generated between said central structure and said external body as a function of the pressure of a liquid introduced into the means for the flow of fluids, which brings about opening of said blades. A load adjustable spring biases the blades into two positions of use depending on the fluid pressure
