Zusammenfassung:PURPOSE:To generate a sufficient tip supporting force with a steel pipe pile with rotary penetration having a large dia. over 600mm. CONSTITUTION:The ground 1 in the position where a pile is to be installed, is in advance excavated to near the setting depth specified, and cement powder is injected to the area around where setting foremost is planned, and then a rotarily penetrating steel pipe pile 5 is driven to the setting depth. Thereby the cement powder is mixed with the surrounding earth and sand and the subsoil water with penetrating of the pile to generate a soil cement 6, which blocks the tip of the pile.
