<P>PROBLEM TO BE SOLVED: To provide a tool for measuring a pile position capable of easily and accurately measuring the pile position by directly measuring the position of a pile head section. Ž<P>SOLUTION: This tool for measuring a pile position is used for measuring the position of a pile 51 by engaging with the upper opening 57 of the pile 51 inserted into an excavated hole 52. The tool includes a level 8 provided to the center of a body 2 and an enlarged section 6 for positioning the body 2 at the center of the upper opening 57. Since the enlarged section 6 is engaged with the upper opening 57 and the center of the body 2 is positioned vertically by the level 8, the center of the body 2 is positioned at the center of the upper opening 57. The center of the upper opening 57 can be accurately measured by measuring a vertical rod 3 which indicates the reference position of the tool 1. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
