OBLIQUE ANGLE MEASURING DEVICE AND OBLIQUE ANGLE MEASURING METHOD FOR BATTER PILE, AND PENETRATION METHOD FOR PILE

摘要

PROBLEM TO BE SOLVED: To provide an oblique angle measuring device and an oblique angle measuring method for a batter pile that easily manage an oblique angle of the batter pile, and a penetration method for a pile in which the batter pile is made to penetrate while the oblique angle is easily managed.

SOLUTION: An oblique angle measuring device that measures the oblique angle of the pile when the pile is made to penetrate obliquely to a ground surface includes: a telescope; a support member supporting the telescope; a base on which the support member is mounted; reference adjusting means for setting a reference line or reference mark viewed through a viewfinder of the telescope to a perpendicular direction; and measuring means for measuring an angle that an external line of the pile and the perpendicular direction contain. An oblique angle measuring method and a penetration method for the pile use the oblique angle measuring device.
