摘要： A device for the movement and mutual assembly of segments of an excavation battery, like for example auger or rod segments, for the composition of an excavation battery and for connecting the battery to a digging machine is disclosed. The device has: an upper joint integrally and removably connectable to a driving tube or to a rotary head of the digging machine; a lower joint integrally and removably connectable to a segment of the excavation battery; a flexible element that connects the two joints being constrained with one own end to the upper joint and connected with the other own end to the lower joint, so that the lower joint can slide along the flexible element moving with respect to the upper joint between a disengaged extended position, and an engaged contracted position; and a stop element that limits the sliding of the lower joint away from the upper joint along the flexible element.

摘要： 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.

摘要： 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.

摘要： 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 associate with a support portion of the auger. Such a support portion defines a proximal section of the helical structure, which has an extension substantially centred 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; Ψ-Ψ) that is not aligned relative to the longitudinal axis (X-X).
