Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a measuring device for a TBM tunnel construction monitoring point. Background Art

[0002] In TBM tunnel construction, the measuring devices at the monitoring points are crucial to ensuring construction safety and project quality. These monitoring points are arranged at key locations in the tunnel. By regularly collecting data, the deformation, stress and environmental changes of the tunnel can be tracked in real time. These data not only help to evaluate the impact of the construction process on the surrounding environment, but also can promptly discover potential safety hazards. The application of measuring devices enables engineers to respond quickly during the construction process and effectively manage emergencies. These monitoring data provide an important basis for the subsequent analysis and evaluation of the project, and enhance the scientificity and accuracy of the construction. In a complex geological environment, systematic monitoring methods have greatly improved the safety and efficiency of TBM tunnel construction, providing a strong guarantee for the smooth progress of the project. Through a strict monitoring system, the stability of the tunnel is ensured, and ultimately a solid foundation is laid for the safe operation of the tunnel.

[0003] After searching, the Chinese patent number CN217155389U discloses a measuring device for monitoring points of TBM tunnel construction, including a tunnel segment, and the middle and top of the side of the tunnel segment are provided with mounting holes. A connecting column is connected by internal threads of three fixing caps, and one side of the inner wall of the three connecting segments is rotatably connected with a positioning column, and one end of the three positioning columns away from the connecting segments is fixedly connected with a positioning disk, and the top side of the outer wall of the three connecting columns is threadedly connected with a locking nut, and then the three positioning columns and the fixing caps can be loosened by unscrewing the locking nut, and the three positioning columns and the three fixing caps can be separated by rotating, so as to facilitate the purpose of rapid installation and disassembly. At the same time, the fixing cap is fixedly connected to the mounting hole by glue, and by providing multiple fixing caps, it is convenient to provide an installation position for the connecting column, so that the user can reuse the positioning column and the positioning disk to measure the inside of the tunnel. Compared with the prior art, the Chinese patent number CN217155389U solves the problem that the existing measuring device is not convenient for installation and disassembly, which has a certain impact on the later reuse.

[0004] However, in actual use of the above device, when the tunnel is large, the placement position of the positioning column is relatively high, and it is difficult, time-consuming and labor-intensive to connect the fixing cap to the positioning column. Moreover, the stability cannot be guaranteed after the connection is completed, and the use effect is not good. Therefore, a measuring device for TBM tunnel construction monitoring points is proposed. Summary of the invention
