However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] In the prior art, when shield segments are used for a long time, the inside of the shield segments will be corroded, causing internal damage to the shield segments. The quality of the shield segments is directly related to the overall quality and safety of the tunnel. In order to extend the life of the shield segments, damage detection equipment is needed to detect the shield segments. Most of the detection methods use an X-ray machine 308 to detect the shield segments and then analyze the degree of damage. However, during the damage detection of the shield segments, some dust and dirt will be attached to the inner wall of the shield segments. When the X-rays penetrate the shield segments, the dust and dirt will affect the accuracy of the damage results of the segments. In addition, since there will be construction workers performing construction work in the subsequent tunnel, the X-ray machine 308 will emit X-rays during the detection process to generate a large amount of radiation. These radiations will affect the tunnel construction workers and affect their health.

During the rotation process, the cleaning brush plate 217 located at the upper end of the rotating special-shaped seat 107 can be linked to reciprocate to clean the dust and soil on the inner wall of the shield segment, so as to facilitate the subsequent X-ray machine 308 to perform damage detection on the shield segment, thereby improving the practicality of the damage testing equipment and the accuracy of detection. At the same time, the X-ray machine 308 can be driven to rotate to realize flaw detection of shield segments at different positions of the tunnel, and then the X-ray machine 308 is pushed to move toward the shield segment to be detected by closely adhering to the flaw detection mechanism 300. During the movement, the protective cover 307 can be linked to move between the shield segment and the flaw detection head of the X-ray machine 308. The protective cover 307 isolates the radiation generated during the detection of the X-ray machine 308, so that the damage detection equipment has the function of isolating radiation, and automatically realizes the two-in-one effect of flaw detection and radiation protection, thereby once again improving the practicality of the damage testing equipment.
