[0002] Segment bolts are fasteners used to connect segments in tunnel construction, which are divided into types such as circumferential, longitudinal, double-headed, and arc-shaped, with different strength grades and surface treatments. Segment bolts are key components connecting tunnel segments, and their quality is directly related to the safe operation of the tunnel. Therefore, in actual engineering, the detection of segment bolts is very important.

At the same time, the measuring rod 404 is driven to move in the direction of the first calibration plate 501 by the first limit seat 401. Then, the chord height of the segment bolt is read through the data pointed by the other end of the measuring rod 404 to the second scale 504. The arc length and the central angle corresponding to the segment bolt are calculated through the chord length and the chord height. When the chord length and the chord height of the segment bolt are inconsistent with the standard data and are not proportional, the segment bolt does not meet the standard.
