A perpendicularity control pile is provided to let anyone in a construction site know the perpendicularity of a pile, and to perform complementary construction if the perpendicularity of a pile does not coincide with the standards by checking the perpendicularity of a pile after completing the pile construction work. A perpendicularity control pile(100) comprises a pile main body(110), an angle meter(130) embedded in the upper circumference of the pile main body in four directions, and a water level meter(120) installed to the center of the pile main body and formed to check the location of air bubbles contained in liquid through a transparent plate. |
