Abstract

Rods, tubes, posts, and the like rod structures are driven into the ground by a device which is successively clamped to selected intermediate portions of the lengths of these rods to avoid heretofore involved awkwardness, instability, and unsafe driving conditions encountered when the top ends of long rods are engaged to force the rods into the ground. The device is easily and quickly clamped to the rod at a level close to the ground to be impacted by a driving tool such as a jackhammer at a convenient reachable height. When the device is driven to ground level, it is easily released from the rod and raised to a starting level and then reclamped for the next driving increment. The successive raising and driving steps are repeated until the rod is driven to a desired depth in the ground. When the top end of the rod approaches ground level, the device can be mounted over this end and impacted to drive the rod further into the ground. A driving shank is slidably retained in a socket of the device spaced laterally from the clamp rod and inclined toward the rod so that the device will deliver type impact blow substantially along the axis of the rod to minimize bending. The device is especially useful for rods which drive ground anchors into the ground.
