    摘要: A boring apparatus for producing a bore within a support tube in the ground. The boring apparatus comprises a housing which is introducible into the support tube and is non-rotatably fixable to the support tube, a cutting device for removing ground material, a rotary drive for driving the cutting device in rotation and a feeding device, by way of which a flushing fluid can be fed into a region of the cutting device. Arranged above the cutting device is a receptacle, into which removed ground material is deliverable by way of the flushing fluid. Provided in the receptacle is at least one stirring element for mixing the removed ground material with the flushing fluid. The removed ground material is upwardly dischargeable out of the receptacle together with the flushing fluid by means of a discharging device. The invention also relates to a method for producing a bore in the ground.
