Abstract
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.
Claims13
Cleaning device for cleaning a bottom (6) of a borehole (2) in the ground, with a pumping means (14), through which sedimented ground material in the region of the bottom (6) of the borehole (2) can be sucked away via a suction opening (16) and discharged from the borehole (2) via a suction line (20),
- wherein
- at least one flushing nozzle (34) is provided, through which a flushing jet (35) can be produced, which exits the cleaning device (10) and flushes sedimented ground material (8) from the bottom (6) of the borehole (2).
Method for creating a foundation element, wherein a borehole (2) is incorporated in the ground, the borehole (2) is filled with a hardenable suspension which hardens to form the foundation element, wherein, before hardening of the foundation element, a cleaning device (10) is lowered to the bottom (6) of the borehole (2), through which sedimented ground material (8) in the region of the bottom (2) is sucked away and removed via a suction opening (16),
- wherein
- a cleaning device (10) with at least one flushing nozzle (34) is used, with which a flushing jet (35) is produced, through which sedimented ground material (8) is flushed from the bottom (6) of the borehole (2).
