摘要
The method involves passing a base plate through a drill hole having smaller diameter. A deep floor plastering with larger diameter takes place under the base plate. The process steps are implemented together with a drill pipe attached bore and mixed tool without pulling a drill pipe. The deep floor plastering takes place with the diameter that is variable by the height. An independent claim is also included for a bore and mixed tool.
