Document Type and Number:
Japanese Patent JP3416655
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary embedding pile which can be produced easily, without deformation, vertically embedded at a high penetration speed, moreover, there is almost no earth to be discharged, a high adhesion to ambient ground, a frictional force increased, thereby greatly improving the bearing force of this rotating and embedding pile.
SOLUTION: Caved valley portion 9 is formed with the tip side of the steel pipe 2 directed from three directions of the outer periphery of the steel pipe 2 to the center, between these valley portions 9, the tip side is closed, three blades 10 of the rear side is sequentially swelled in the peripheral direction and protruded in a radial shape.
