Abstract: A method and device for lining a bore shaft extending through an aquiferous formation comprises, lowering a base ring on guide and alignment columns into the bore until the base ring is seated on a shoulder near the bottom of the bore which is at or below the lower end of the aquiferous formation. The base ring with connected columns are then centered in the bore. A plurality of lining rings are then sequentially lowered in a guided and aligned fashion on the column to rest on the base ring and on each other and to form sealing joints therebetween. The space between the thus formed lining and the bore can then be filled with filler material.
