<p>A method of forming a foundation with a hollow-section reaming tube (100). The method includes drilling a pilot bore-hole to a required depth and reaming the pilot borehole by rotating the hollow section reaming tube which is subsequently not retracted. The hollow section reaming tube (100) comprises at least one tube section (103) adapted to connect with another tube section (102) via corresponding screw threads (104).</p> |
