Abstract (en)
[origin: US2016083927A1] The invention relates to a cleaning device for cleaning a bottom of a borehole in the ground and also to a method for creating a bored pile in a borehole. The cleaning device has a pumping means, through which sedimented ground material in the region of the bottom of the borehole can be sucked away via a suction opening and can be discharged from the borehole via a suction line. At least one flushing nozzle is provided, through which a flushing jet can be produced, which exits the cleaning device and flushes sedimented ground material from the bottom of the borehole. A bored pile can then be produced in a thus cleaned borehole.
