Sposób polega na tym, że po zabetonowaniu otworu pala i osiągnięciu przewidywanego poziomu mieszanki betonowej formującej trzon pala odcina się dopływ mieszanki betonowej (4) i doprowadza się do rdzenia świdra ciecz stabilizującą (5), którą wypełnia się otwór powyżej poziomu głowicy pala z jednoczesnym podciąganiem świdra. Do doprowadzania mieszanki betonowej (4), a następnie cieczy stabilizującej (5) służy trójnik (3) z zasuwą, który steruje dopływ mieszanki (4) lub cieczy (5) do rdzenia świdra.The method consists in that after concreting the pile opening and reaching the expected level of the concrete mixture forming the pile shaft, the inflow of the concrete mix is cut off and a stabilizing liquid (5) is fed to the drill bit, which fills the hole above the level of the pile head with simultaneous pulling up the auger. To supply the concrete mix (4), followed by the stabilizing liquid (5), a tee (3) with a gate valve is used to control the flow of mix (4) or liquid (5) to the drill bit core.
