Abstract
PURPOSE: To bore a small diameter slot in the ground through the longitudinal movement of a drill rod caused by a longitudinal rod movement device and through the action of a boring tool caused by the reciprocating movement of a hammer. CONSTITUTION: A drill rig R is mounted on a trajectory 14 and the console of the rig R is advanced along the trajectory 14. A motor 23 for rotating a hollow drill rod or a pipe 15 is provided. The console 24 has a control handle 16 whereby the advance of the console 24 along the trajectory 14, the selective rotation of the drill rod 15, and the maintaining of the drill rod 15 in a non- rotating condition are determined. The rear end of the drill rod 15 is connected to a compressed air source via a connector 25 and a duct 26. Compressed air is supplied to a pneumatic boring tool 17 via the drill rod 15 to actuate a hammer to strike an anvil member connected to an external boring element.
