Device (1) for consolidating soils by means of mechanical mixing and injection of consolidating fluids, which 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 (10), one or more blades (30) (30') (30"), which are mobile with respect to the body (10) and are constrained by means of cams (22) to a central structure (20) internal to the body (10); the device (1) moreover has channels for the flow of fluids (40), which are connected in a liquid-tight way to at least one sprayer; a rela-tive motion is generated between the central structure (20) and the external body (10) as a function of the pressure of a liquid introduced into the channels for the flow of fluids (40), which brings about opening of the blades (30) (30') (30").
La présente invention concerne un dispositif (1) pour consolider des sols au moyen de mélange mécanique et dinjection de fluides de consolidation qui est conçu pour être relié à une ou plusieurs tiges de forage et pour réaliser des opérations de forage et de mélange ; le dispositif comporte un corps principal (10), une ou plusieurs lames (30) (30') (30"), qui sont mobiles par rapport au corps (10) et sont contraintes au moyen de cames (22) sur une structure centrale (20) interne au corps (10) ; le dispositif (1) comporte en outre des canaux pour lécoulement de fluides (40), qui sont raccordés de façon étanche aux liquides à au moins un pulvérisateur ; un mouvement relatif est généré entre la structure centrale (20) et le corps externe (10) en fonction de la pression dun liquide introduit dans les canaux pour lécoulement des fluides (40), qui entraîne louverture des lames (30) (30') (30").
