Abstract
Equipment serves to form consolidated soil columns having a non-circular cross-section, and includes a mast (), a rotary () which is rotatable and translatable along an axis parallel to the mast, a series of hollow rods () temporarily unlockable from the rotary (), and a device to vary the rotational rate of the rotary in one or more prefixed angular ranges. A rotor () is directly secured to one of the rods of the string and operatively coupled to a device () generating control signals to vary the rotational speed of the rotary in response to the rotor angular position. A through clamp () is mounted to the rotatable mandrel of the rotary and is provided with locking members which can be activated to clamp a rod and make it integral to the rotary, and which can be deactivated to release the rod so as to allow the rotary to move relative to the rod.
