AI Technical Summary

Technical Problem

In traditional tunnel construction, the target position control is inaccurate during pipe jacking guidance measurement, resulting in measurement results that do not match the actual situation, which affects the accuracy and stability of tunnel structure monitoring.

Method used

A target device for measuring pipe curtain in tunnel construction was designed, including a pipe body, a support frame, a guide tube, a mounting shell, a prism, a connecting rod, and a roller assembly. By setting the support frame and the pipe body concentrically and reducing frictional resistance with the roller assembly, the target device is ensured to be accurately positioned and stably guided during pipe curtain construction.

Benefits of technology

This improved the effectiveness of measurement results, ensured the accuracy and stability of target positions, reduced measurement errors caused by construction vibration and friction, and enabled precise monitoring of tunnel structures.
