A device for detecting roundness and assembly staggering of segments is characterized in that a piezochromic coating is arranged on the outer side surface of a detection plate, a handle is arranged in the center of the inner side of the detection plate, the piezochromic coating is made of a piezochromic organic coating, during detection, an arc-shaped plate is pressed on the inner side of a segment, and according to the color development condition of the coating on the arc-shaped plate, the roundness of the segment is detected. According to the device, the roundness of the duct pieces can be detected before the duct pieces enter a field, the quality of the duct pieces is ensured, the circumferential slab staggering can be detected when the duct pieces are assembled, so that assembling adjustment is facilitated, and the device has the advantages of being low in cost, easy to carry, convenient and fast to operate, good in applicability and the like. The device can be popularized and applied to the technical fie
