Abstract

See full text

A single-pass type drilling machine includes a guide tower, a string of drilling rods, an extension element having an upper end and a lower end with the lower end being coupled with an upper end of the string of drilling rods, a rotary head slidably coupled with the guide tower, and a detection system. The rotary head and the extension element are mutually slidable and arranged to couple with each other in an upper end stop position, where the rotary head is coupled with the extension element substantially at the upper end of the extension element. The rotary head is coupled with the extension element at a lower position with respect to the upper end stop position in at least one locking position. The detection system detects the reaching of the at least one locking position by detecting at least the mutual axial position of the extension element and the rotary head.
