Core removal, from waste storage container, involves drilling concrete element with cylindrical tool, sawing, and removal of core for re-encasement

摘要

A process for removing a core (13) from a cylindrical concrete element, especially for the transfer of concrete encased waste in a storage container, involves placing the concrete element (11) in a work position and drilling the concrete using a cylindrical tool (20) until the desired depth is reached. The concrete element is sawed laterally to its axis, so the saw cut (31) passes through the bored channel, allowing the core to be removed.
