Its main function is to fix the tunnel wall, reinforce the tunnel structure, and make the tunnel have better bearing capacity and stability. The finished size of the segment is the guarantee of the tunnel forming quality. When the segment is prepared, its size needs to be accurately measured. Therefore, a segment size inspection device is needed. The existing segment size inspection device mainly uses measuring tools such as rulers and calipers to measure the length, height, thickness, etc. of the segment. When the curvature of the segment needs to be measured, the standard template needs to be placed against the curved surface of the segment, and the gap between the outer measuring surface of the segment and the template needs to be measured with a feeler gauge.

[0003] Based on the above, when the existing segment size inspection device measures the curvature, it is necessary to use a feeler gauge to measure the gap between the outer measuring surface of the segment and the template, and take multiple measuring points for measurement.

Therefore, the measurement results are prone to errors and disputes, and the measurement operation workload is large, which is not conducive to the efficiency of size measurement.
