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.

A method of lining a bore shaft extending through an aquiferous formation comprising:
- boring the bore shaft through the aquiferous formation to form a shoulder below a lower boundary of the aquiferous formation;
- detachably connecting a plurality of guide and alignment columns to a base ring;
- lowering the base ring and plurality of columns into the bore shaft to seat the base ring on the bore shoulder;
- centering the base ring and columns in the bore shaft;
- subsequently lowering and guiding one lining ring at a time on the column into the bore shaft and onto one of the base rings and a previously-lowered lining ring to form a sealing joint therewith, the base ring and lining rings stacked to form a lining tube in the bore shaft;
- and
- forming each of the lining rings and base ring to have water-tight tongue and groove sealing joints therebetween.
