Abstract (en)
[origin: EP0732452A1] The stamp (14) is set in rotation by a rotary drive (13) and is pressed into the ground along a linear guide (3), fitted on a frame (2) of the device, by a positioning drive (1). At the free end (17) of the stamp is an upwardly widening penetration head (18). The penetration head has at least one through-passage (20) which connects the space on the conveyor worm with the space (43) beneath the penetration head. The penetration head is rotation-symmetrically formed and at its widest point has a greater dia. (D1) than the conveyor worm (16). The penetration head is formed by a reinforced end of the conveyor worm, which in the area of its free end is provided with at least two spirals.
