摘要： PROBLEM TO BE SOLVED: To provide a method of easily and surely burying an anchor for a suspension in almost soils such as boulder stones, coarse fragments, and rock parts even in the direction perpendicular to a slope.
SOLUTION: A ring bit is attached to the end of a pipe for burying rotatably relative to each other. A pilot bit locked and formed integrally with the ring bit in normal rotating direction and unlocked in the reverse direction is inserted into the pipe. The pilot bit ring and the ring bit are rotated in synchronism with each other to propel the pipe. When the pipe reaches to a predetermined depth, the pilot bit is reversely rotated to separate the pilot bit from the ring bit. The pilot bit is extracted from the pipe to bury the anchor.
