Disclosed is a device for boring and setting anchors, comprising a boring bar (1), a telescopable supporting mechanism (3) at the top, a boring motor (7), and clamping jaws (11, 12) that are fixed to the supporting mechanism (3) and are used for clamping the boring bar (1) when mounting boring bar extensions. The inventive device further comprises a cylindrical sealing sleeve (9) which supports a sealing element (14) overlapping the edge of the sealing sleeve (9) on the face that faces the supporting mechanism (3) while supporting a sealing element (21) penetrated by the boring bar (1) on the face that faces away from the supporting mechanism (3). Said sealing element (21) seals the cylindrical space (24) of the sealing sleeve (9) in the direction of the axis of the boring bar (1). A duct for leading away (25) borings and optional boring fluid is connected to the outer coating (13) of the sealing sleeve (9) between the two sealing elements (14,21). |
