PROBLEM TO BE SOLVED: To provide a friction pile of a base-protruded protrusion anchor pile, which can stabilize a pile itself even if the pile is buried in soft ground, and can keep the once buried pile in a stable state in soil even if vibrations are generated by earthquakes etc. SOLUTION: This base-protruded protrusion anchor pile is buried in the ground by being rotated and pressed in through the use of a soil-excavating metal blade in a lower part of a pile body 1 and excavating screws 11 which are separately fixed to several important places of a side surface of the pile body 1. After that, base-protruded protrusion anchors, which are precedently housed and built in important places inside the pile body 1, are protruded by a base-pushing steel pipe. The base-protruded protrusion anchors are stuck in side-wall soil outside the pile body 1, so that the base-protruded protrusion anchor pile can be firmly stabilized. COPYRIGHT: (C)2004,JPO
