Universal precise leveling measuring device and measurement method thereof

The present invention relates to a universal precise leveling measuring device and a measurement method thereof, comprising: a plate-shaped horizontal base, a round bubble level set at the center of an upper surface of the base, and three outriggers set on the base, wherein at least one through-hole is set at one end of each of the outriggers far from the base, and a point contact bolt set in the through-hole; the three outriggers are extended in different directions and in the same plane parallel to the base, and included angle of two adjacent outriggers is smaller than 180°. With the universal precise leveling measuring device of the present invention, the prior art manual levelness measurement of foundation flange of wind power generator carried out by using a scale and a level is modified into dynamic measurement carried out only by using the universal precise leveling measuring device, thus increasing the measurement precision, simplifying the measurement procedures, reducing the workload of the operator, and further guaranteeing the construction quality and performance of various foundations of the wind power generator set.
