A Spiral Auger and A Method for Soil Cement Pile using it

CHOI YOUNG JUN / KIM CHANG HYUN

The present invention relates to a spiral drilling auger having a plurality of cutter blades which protrude from an outer circumferential surface of a rod having a vertically spiral shape to enable a gap to be formed between the adjacent cutter blades, wherein the protruding length of the cutter blade is reduced from an upper side to a lower side. The present invention prevents aggregation of the soil during a drilling and a withdrawal process to simplify the following process.

본 발명은 롯드 외주연에 상,하로 나선형을 이루며 돌출된 복수의 커터날이 구성되어 인접하는 커터날 간에는 유격이 형성되도록 하며, 상방향에서 하방향으로 커터날의 돌출된 길이가 작아지는 것을 특징으로 하는 나선형 천공오거에 관한 것이다.
