<P>PROBLEM TO BE SOLVED: To provide an agitation apparatus for a concrete pole in which the fatigue of a checker can be reduced and further, more accurate vibration data can be acquired. <P>SOLUTION: An agitation apparatus includes a hammer 11 which strikes a concrete pole 5 to agitate it, a crossbow unit 2 in a bow-shaped spring structure for giving an energizing force to the hammer 11, a main body unit 3 in a gun-shaped structure for pulling a trigger to pull the hammer 11 closer and to store the energizing force in the bow-shaped spring structure, perfectly pulling the trigger to strike the hammer with the energizing force of the bow-shaped spring structure, and returning the trigger to the original position after striking, and an agitation direction fixing unit 4 which has a leaf spring structure and is provided in the main body unit 3 so as to hold the concrete hole 5 between leaf body surfaces of leaf springs and along a circumferential surface of the concrete pole 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
