Abstract
A device () for drilling and tamping grounds is constituted by a tamping tip (A) rigidly connected to a shaft () which constitutes the connection to the end part of a battery of rods moved by a drilling machine, which gives it movement in a vertical direction and a rotation around its longitudinal axis. The battery of rods is inserted into a covering tube (). Between the tamping tip (A) and the tube () a substantially cylindrical tamping element () is interposed, adapted to define a tamping diameter of the ground which forms the walls of the hole obtained by the device () at least equal to the diameter of the tube ().
