Abstract

A device for geotechnical sampling. A core barrel (14) is intended to be applied to the lower end of a drill pipe (10) which is driven down into the ground with the aid of percussion and/or rotary drilling. The core barrel (14) is connected to an expandable sleeve (22). To retain the core barrel a positive pressure is generated inside the sleeve (22) to expand the walls thereof, whereby the walls will abut against the walls of the drill pipe (10). In this manner the sleeve (22) and the core barrel (14) are safely secured during the sampling operation. When the core barrel is filled, the pressure inside the sleeve (22) is reduced and the core barrel is pulled upwards through the drill pipe (10).
