The invention relates to the field of building construction, aims to solve the problem that a rotary excavating pile perpendicularity measuring device in the prior art is inconvenient to operate or high in measuring equipment cost, and provides a rotary excavating pile perpendicularity detecting device and method. The rotary excavating pile perpendicularity detecting device comprises a lower circular ring, an upper circular ring, a laser pen, a measuring ruler and a plurality of connecting ropes. The lower circular ring comprises a lower inner ring and a lower outer ring which are concentric,and a lower cross-shaped steel bar; the periphery of the lower outer ring is matched with a pile hole wall of a rotary excavating pile to be detected, and reflective stripes are arranged on the lowerinner ring and the lower cross-shaped steel bar in a matched mode; the upper circular ring comprises an upper inner ring and an upper outer ring which are concentric, and an upper cross-shaped steel bar; the lengths of the plu
