PROBLEM TO BE SOLVED: To solve a problem wherein a bar-like handle is conventionally mounted to the upper end of a spiral pile and manually rotated as a spiral pile erecting implement for erecting the spiral pile in a field or the like, but if there is another erected spiral pile or the like in the vicinity, the handle abuts on the pile and cannot be rotated as expected. SOLUTION: The spiral pile erecting implement is provided for erecting on the ground the spiral pile having a spiral X1 on the tip side and a mounting part X3 on the base end side. A surrounding body 4 is put over the mounting part X3, and a spiral pile body X2 is put in a recess 7a of a projecting body 7 formed at the lower end of a locking-fixing member 5 turnably mounted to the surrounding body 4. The locking-fixing member 5 is brought into pressure contact with the spiral pile body X2 by a coil spring 6a, and the handle and the spiral pile body are held almost perpendicularly. The handle 1 locked to the surrounding body 4 has a ratchet mechanism 2. COPYRIGHT: (C)2009,JPO&INPIT
