[0002] With the vigorous development of subway shield construction in China, more and more shield tunnels are being built. Segment misalignment refers to the uneven inner arc surface between adjacent segments in the same ring or between adjacent segments after segment assembly. Segment misalignment not only affects the appearance quality of the tunnel, but also leads to a series of problems such as segment rupture, tunnel leakage, and shield tail brush damage. Therefore, it is extremely necessary to measure the misalignment height of shield tunnel segments in daily tunnel safety maintenance.

[0003] The detection of shield lining segment misalignment is generally done manually with a simple ruler. The use of a simple ruler for manual detection has the problems of being too simple, arbitrary, and having large errors. Therefore, it is necessary to study an adjustable ruler for detecting misalignment of lining segments that is simple and accurate enough to meet the requirements of engineering quantity measurement.

[0009] In some embodiments, a limiter and handle device is provided on the main ruler to prevent the caliper from slipping.

[0010] In some embodiments, the main ruler includes four opposing scales, which are vertically connected to each other to form a cube.

[0011] In some embodiments, the scale is a transparent scale, and a light strip along the scale line is attached to the inner side of the scale, and the light strip is electrically connected to the battery in the main scale.
