Claims

[Scope of Claim for Utility Model Registration] {1} An embedded flying hollow pile characterized in that at least a lower end portion thereof is provided with a soil-lifting part that scoops and lifts soil into the hollow by rotating the pile. (2) The hollow pile for embedding according to claim 1, wherein the soil lifting action portion is a spiral protrusion or blade formed in the hollow. (3) The hollow pile for embedding according to claim 1, wherein the soil lifting action portion is a discontinuous inclined protrusion provided on the inner surface of the hollow. (4) The hollow pile for embedding according to any one of claims 1 to 3 of the claims for utility model registration, wherein the soil lifting action part is integrally precast on the inner surface of the hollow pile. . “(5) The earth lifting action portion is a hollow pit for embedding according to any one of claims 1 to 3 of the utility model registration claim, which is formed in the insert ring during precast molding. (6F A hollow pile for embedding according to claim 5 of the utility model registration claim in which the insert ring is the same precast molded product as the hollow pile. (7) Utility model registration claim in which the insert ring is made of metal. The hollow pile for embedding according to the scope of claim 5. {8} The soil lifting action part is formed in the rear-fitting ring body. (9) The hollow pile for embedding according to claim 1, wherein the soil lifting action part is a radial wing part arranged radially in the hollow part. 1G A hollow pile for embedding according to claim 9 of the patented utility model registration claim in which the wing part has a sloped face due to the rotation of the pile. (11) A utility model registration in which the wing part is formed at the bottom of the lower end. Hollow pile for embedding according to claim 1. (12) The soil lifting action portion is formed to extend to the lower end surface of the pile. Hollow pile for embedding as described in (l3) The soil lifting action part is the part that extends to the lower end face of the pile.
13. A hollow pile for drilling according to claim 12, which is provided with a torsion angle on the center side of the pile due to rotation of the pile. (14) The hollow pile for embedding according to claim 1, wherein the soil lifting action portion is formed so as not to protrude inward from the inner diameter surface.
