A modular assembly for handling excavating equipment is disclosed. The assembly includes a first rotating table having a main body; one or more motors, each having a pinion, associated with the main body; a bearing having a fixed ring constrained to the main body and a movable ring that is coaxial and rotatable with respect to the fixed ring; a dragging sleeve integrally coupled with the movable ring coaxially to the bearing; a ring gear integrally and coaxially coupled with the dragging sleeve to engage with the pinion and be moved in rotation by the motors rotating integrally with the dragging sleeve and integrally with the movable ring. The assembly also has a second rotating table adapted to be coupled to a continuous excavating propeller; a plurality of accessories associated with the first rotating table so it can be coupled to a telescopic Kelly rod or to a continuous excavating propeller or to a casing and excavating pipe.

A device is provided for the movement and mutual assembly of segments of an excavation battery. The device includes four parts: an upper joint, a lower joint, a flexible element and a stop element. The upper joint is connectable to a driving tube. The lower joint is connectable to one segment of the excavation battery. The flexible element connects the upper joint to the lower joint so that the lower joint slides along the flexible element. The stop element limits the sliding of the lower joint away from the upper joint, and includes a ballast with a diameter that is less than a diameter of an inner duct in one segment of the excavation battery.

A tubing device is operatively connectable to an excavation machine. The tubing device comprises a base frame, at least one guiding tower operatively connected to the base frame, and a tube operating unit, operatively connected to the guiding tower. The tube operating unit is slidable along the guiding tower and is provided with engaging means capable of both selectively holding a tube segment, and of transmitting a rotary motion and an axial sliding movement to such a tube segment so as to allow the progressive driving in the ground and subsequent extraction from the ground.

Disclosed a device for digging diaphragms, including a framework and a half-shell support body, fixed in the lower part of the framework, which supports a first pair of half-shells moved to open and close by a first actuation system. The device also has a reservoir operatively connected to the first pair of half-shells to contain the soil dug by half-shells. The reservoir is normally positioned between the framework and the half-shells and has a volume configured to contain an amount of soil corresponding to the amount of soil dug by such half-shells during a single operating cycle of the device. The device can also include separation means actuated for isolating the soil contained in the reservoir.

A modular system of multipurpose rods for drilling soil is constituted by rods () crossed by an internal passage () for the passage of concrete, of substantially cylindrical shape, that completely crosses the rod; each of the rods is provided at the endings with a male insert () and a female insert () respectively, adapted to be plugged in one to the other for permitting the assembly in batteries of any length. The inserts () are provided with transmitters () for transmitting the rotation along the whole battery of rods () and arranged for fixing elements that reduce the internal passage ().

The helical drill bit defines a helical end section of a helical structure formed at its periphery by an auger of an excavation assembly, and it is associated or associable with a support portion of the auger. Such a support portion defines a proximal section of the helical structure, which has an extension substantially centered around a longitudinal axis (X-X). The helical drill bit is adapted to rotate about the longitudinal axis (X-X) together with the support portion so as to drill a hole in the ground. The helical end section extends around an extremity axis (Y-Y; &#x3a8;-&#x3a8;) that is not aligned relative to the longitudinal axis (X-X).
