Abstract: A method of mounting a kelly bar on a drilling machine includes a step of installing a mounting tool between the rod of a pull-down cylinder and a rotary carriage of the drilling machine. Once the mounting tool has been installed, the drilling machine can be set up with a kelly bar that is longer than the usual kelly bars.

Abstract: 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.

Abstract: The invention describes a tubing device of the type operatively connectable to an excavation machine and configured to perform an excavation in the ground contained, at least partially, inside at least one tube segment. The tubing device comprises a base frame, at least one guiding tower for the tube segment, 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 the 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. The axial sliding movement is guided by the guiding tower and the width of such axial sliding movement is determined by the stroke of the tube operating unit on such a guiding tower and is proportional to at least once the diameter of the tube segment.
