Abstract
The invention relates to a drilling bucket and a method for producing a bore with a drilling bucket, wherein the drilling bucket is driven in a rotating manner and introduced into the ground, wherein ground material is removed and received in an internal space of a tubular base body of the drilling bucket, and for emptying the drilling bucket is withdrawn from the bore and a bottom on the tubular base body is folded open. According to the invention the drilling bucket is rotated in a reversing manner during emptying, wherein ground material received in the drilling bucket is pressed against at least one impact wall and, in doing so, the ground material is specifically compacted and deformed for easier loosening from the internal space.
