摘要： An injection head includes an upper inlet pipe (12) for receiving fluid from a set of tubular rods which can be mounted above the head, at least a first pipe (13) having a curved intermediate portion (14) which connects the upper inlet pipe (12) to at least one lateral injection nozzle (11), at least a second pipe (15) for conveying a fluid from the inlet pipe (12) to a lower outlet pipe (17) which can be connected to a drilling tool. The injection head also has valve (20-23) which can be actuated to cut off the flow of the fluid towards the lower outlet pipe (17). The valve is located in a position downstream of the upper inlet pipe (12) and above, or upstream of, the lateral nozzles (11) and the second pipes (15).

摘要： The equipment serves to form consolidated soil columns having a non-circular cross- section, and comprises a mast (2, 8), a rotary (3) which is rotatable and translatable along an axis parallel to the mast, a series of hollow rods (4) temporarily unlockable from the ro¬ tary (3), and a device to vary the rotational rate of the rotary in one or more prefixed angu¬ lar ranges. A rotor (21) is directly secured to one of the rods of the string and operatively coupled to a device (20) generating control signals to vary the rotational speed of the rotary in response to the rotor angular position. A through clamp (10) 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.

摘要： Equipment for drilling secant holes (2) constituted by an excavating system (3, 14, 4, 16, and 17) and by a guide system (7, 8), both of which are set in the hole (2) being drilled and in a previously made hole (2'), the two systems being fixed with respect to one another in such a way as to define a pre-set distance between centres of the holes; the excavating system comprising a rotation means (3) and a bit (4) connected thereto, and being completely introduced into the borehole.
