	Implementation Procedure



1.	Casing pipe is positioned and predetermined quantity of filling material is charged into the casing.

2.	Casing is rotated and driven smoothly into the ground.

3.	Casing is fully penetrated to the designated depth.

4.	While casing is lifted by predetermined height, filling material is discharged from the casing.

5.	Casing is re-driven to compact discharged filling material and surrounding ground.

6.	Steps 4 and 5 are repeated by using a wave pattern and casing is gradually lifted, consequently formation of an enlarged pile is achieved.
