DRILLING APPARATUS FOR CREATING A BOREHOLE
The application relates to a drilling apparatus (10) for creating a borehole in the ground, having a basic body (11), having a drilling tool (15, 17) which is arranged at one end of the basic body (11), having a drive provided on the basic body for the drilling tool, and having a bracing device (30) which is designed for bracing the drilling apparatus (10) in a cylindrical hollow body (20) and which has at least one bracing plane (31, 32) with at least two bracing elements (33, 34) which are arranged with a first end on the basic body (11) and which have at least one bracing body (35, 36) at their second end, wherein the at least one bracing body of the bracing element is movable from a first position to a second position by means of at least one drive (37), wherein the bracing body (35, 36) provides a form-fitting connection between the basic body and the hollow body via at least one element on the inner wall of the hollow body.
