With the rapid development of urban rail transit construction, subway projects, as a crucial component of urban infrastructure, directly impact urban operational efficiency and residents' quality of life. Therefore, rigorous monitoring and quality control of the subway construction process are particularly important. Subway construction quality testing equipment ensures that project quality meets design requirements and relevant standards by monitoring and analyzing various parameters during construction in real time, thus guaranteeing the safety and reliability of subway construction.

[0003] Testing equipment is usually mounted on a testing platform. During testing, uneven ground in some areas can prevent the device from maintaining a level position, which can affect the final testing results.

[0004] A search revealed a patent document with publication number CN 223130653 U, which discloses an engineering quality testing device for subway construction, addressing the problems existing in the aforementioned prior art.

[0005] While the existing technologies address the current problems, it has been found that subway construction paths are long, and these technologies can only be placed on the ground for horizontal inspection, making it impossible to perform mobile inspection, which affects inspection efficiency. Therefore, a new engineering quality inspection device for subway construction is proposed to optimize the existing technologies and solve their problems. Utility Model Content
