Abstract
Device () for consolidating soils by mechanical mixing and injection of consolidating fluids is designed to be connected to one or more drilling rods and to carry out operations of drilling and mixing. The device has a main body (), one or more blades () (') (″), which are mobile with respect to the body () and are constrained by cams () to a central structure () internal to the body (). The device () has channels for the flow of fluids (), which are connected in a liquid-tight way to at least one sprayer; a relative motion is generated between the central structure () and the external body () as a function of the pressure of a liquid introduced into the channels for the flow of fluids (), which brings about opening of the blades () (′) (″).
