ABSTRACT:
A unit adapted to be attached to a large number of similar units to form an apparatus to permit the taking of geological and geophysical readings and samples. The apparatus comprises a cylindrical casing having ribs or grooves formed on its interior surface. A coupler is adapted to fit on the casing. Alignment means are formed on the casing and the coupler to co-operate to ensure alignment of the grooves in the casing with the grooves in an adjacent casing in the apparatus. Expandable bags may be attached to the exterior of the casing to help provide support and hydraulic seals between the casing and the surrounding materials.
