The underground part is made of the following components joined to each other by means of welding - a pipe with length l_pipe and round cross section and a tubular cone with a truncated top with height l_cone=(0.3-0.5)l_pipe. A triangular plate twisted along the screw is welded to the cone cut with a sharp angle down. In the connecting plate of the underground part there is a central hole for engagement with a rotary tool. The cone surface and the lower section of the pipe with length l_turns=(0.3-0.5)l_pipe are equipped with helical ribs with the inclination angle of 5-10° to the support axis.
