The invention discloses a detecting method of pile forming quality in reinforced concrete structures or hard overall base rocks, belongs to the technical field of construction processes and quality control in water conservancy and hydropower engineering, and provides the detecting method of the pile forming quality in the reinforced concrete structures or the hard overall base rocks, which can effectively monitor the construction quality of each procedure in the construction process. The detecting method comprises pile hole diameter and perpendicularity detection and concrete pile casting quality detection after casting, wherein when diameters and perpendicularities of pile holes are detected, a reinforcement detecting cage is matched with a total station with a prism function for detection; and when the casting quality of concrete piles is detected after casting, a ultrasonic or drilled core sampling mode is used for detection.
