<p>The method involves drilling an external bore rod (1) into a base (15), where the rod is equipped with a bore-crown (3) at bottom. A coat mixture (16) is inserted directly during boring or after the achievement of an end boring depth by the rod and the bore-crown. An injection medium (18) is injected into an injection tube (4) of an inserted packer (19) after pulling of an interior rod, where the injection tube of the inserted packer remains in the base as a trailing boring- and injection tube with the bore-crown. An independent claim is also included for a device for reinforcement of base sections.</p> |
