Description
For measuring tunnel cross-sectional convergence, this system connects sensors at 1.0 m intervals and measures displacement using high-resolution length and angle sensors to produce accurate results.
▣ Applications
① Measuring cross-sectional convergence of tunnel structures after construction (maintenance monitoring)
② Measuring cross-sectional convergence of underground structures adjacent to construction areas (monitoring during construction)
Composition & Characteristic
▣ Components
① Cross-sectional convergence sensors (length and angle)
② Mounting bracket, extension rod
③ Anchor plate & bolt
▣ Features
① Each sensor cable is integrated into a one-line system, making installation simple and significantly reducing installation time.
② The anchor block angle adjustment and fastening mechanism are easy to operate, simplifying installation.
③ The one-line cable configuration reduces overall installation costs.
