Abstract

The invention discloses apparatus for positioning and use of actuation devices such as geotechnical investigation tools at the end of a drill string. The apparatus includes a casing for accommodating the actuation device and for engaging the lower (leading) end of the drill string such as by latching means. A hydraulic apparatus for extending and retracting the actuation device includes a piston and cylinder. Upper and lower rods are attached to respective sides of the cylinder and the lower rod is attached to the actuation device. The upper rod is attached to a hydraulic control arrangement. The hydraulic control arrangement controls the flow of hydraulic fluid to respective sides of the piston in the cylinder, thereby to move the cylinder and to effect extension and retraction of the actuation device. The latching means are releasable on retraction of the actuation device.
