Abstract
PURPOSE: To facilitate the work for pulling out a ramming rod used when an underground buried article is driven deeply into a firm ground.
CONSTITUTION: A tool rod for ramming composed of a central-part ramming rod 1 and a tubelike ramming rod 4 is made to contact 6 with an underground buried article, while on the upper end thereof a ramming force generating device 15 is mounted. By driving the device 1, a ramming force is applied simultaneously on to the upper-end surface of the central-part ramming rod 1 and that of the tubelike ramming rod 4, thereby rods are driven down to the desired depth in the ground. Next, the above ramming force generating device 15 is removed and a pulling-out device 8 is mounted instead, the tubelike ramming rod 4 is pulled out, by driving the pulling-out device 8, using the top of the rod 1 as a basic point, and subsequently, the central-part ramming rod 1 is pulled out, the article is buried in the ground.
