Abstract
The patent proposes a system of control injection into the ground of consolidating mixtures. It uses pipes provided with choke bags which when inflated tighten around the perforation, defining an intermediate portion in which the mixture is injected and diffused through a porous sleeve. The pipe has holes through which the bags are inflated and the mixture conveyed to the sleeve. These holes are fitted with check valves. <IMAGE>
