| description | The invention discloses a measuring method for controlling the verticality of a steel pipe pile of a wind power foundation. A laser leveling instrument is adopted to measure the flatness and internalinclination of the top surface of a flange; a digital display horizontal ruler and a vertical line are adopted to collect axial projection points of a plurality of cross sections of the steel pipe pile; electronic theodolites are arranged at the positions of the axial projection points at the top end of the steel pipe pile in an erecting mode, and laser points arranged by eyepieces of the electronic theodolites are aligned to the axial projection points at the bottom end of the steel pipe pile to obtain a straightness datum line; the distance between the straightness datum line and each axialprojection point is measured, and a plurality of straightness measurement values are obtained; and the line of sight of the eyepieces of the electronic theodolites is perpendicular to the top surfaceof the flange, then laser p |
