<p>The method involves driving drilling and mixing tools (10) for providing overlapping bore holes, and drilling the tools into a floor. The tools are pulled back from the floor after reaching desired drilling depth. A reinforcement yoke (4) is detachably connected with an intermediate guiding carriage (16) by a connection (1) with a coupling device. The carriage is adjustably guided along a mast guide (3), and the tools are supported by the carriage up to the drilling depth. The connection of the tools with the carriage is detached for drilling a hole. An independent claim is also included for a device for manufacturing a wall panel in a floor.</p> |
