ABSTRACT:
The invention relates to a method for sinking a borehole in the ground, in which a wet boring tool with a removal area for producing or advancing a borehole is used, the borehole is at least partly filled with a fluid and in the borehole is formed a filling area and the removal area is at least partly washed round by a fluid flow, which conveys the bore smalls produced at the removal area to a collecting container located in the borehole. The method according to the invention is characterized in that the wet boring tool has a pumping mechanism through which fluid from the filling area is made to flow and conveys bore smalls produced into the collecting container. The invention also relates to a wet boring tool and to a boring plant.
