Abstract: In a device for sealing a bore hole and discharging drill cuttings and stripped excavation material, including a housing adapted to receive sealing elements and an opening capable of being connected to the bore hole, one side wall of the housing is provided with at least one opening for the connection of a haulage duct, wherein the housing end side facing the bore hole is equipped with a lockable, particularly screwable, sealing flange (13) for the detachable connection with a bore hole lining (11). The sealing flange (13) is rotationally and sealingly mounted within the housing and carries projections, in particular an annular brim (15) which is overlapped by a stop (14) of the housing.

Abstract: In a device for extending and shortening tubings used to transport drill cuttings and stripped material, a tube storage or tube magazine is provided on a frame (1) capable of being supported on the floor, wherein at least one lifting means (3) capable of being displaced in the height direction and intended to lift tubes (17) into a storage position as well as at least one manipulator (13) intended to position a tube removed from the tube storage into a position in alignment with a laid tube track are arranged on the frame (1). The frame includes at least one longitudinal guide (5) for a telescoping tube (7) that is capable of being integrated in the tube track.
