Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a rapid detection system and detection method for tunnel defects. Background technique [0002] With the unprecedented development of railway and highway construction and urban underground transportation construction, the excavation and maintenance of caves and tunnels has become very important, especially in the later maintenance work. Due to the daily use and the special internal environment, the maintenance work has brought great How to establish a comprehensive maintenance plan for caves and tunnels to ensure timely detection of dangers due to disrepair is particularly urgent; [0003] In the maintenance of the tunnel, it is necessary to regularly inspect the inner wall of the tunnel to prevent the occurrence of defects. In the prior art, inspections by workers are usually required. Ordinary inspections are difficult to intuitively reflect the overall situation of th...

[0004]Aiming at the above problems, the present invention proposes a rapid detection system and detection method for tunnel defects. The rapid detection system is equipped with a special intelligent displacement robot in the tunnel. Displacement and MEMS displacement sensor identification, used to measure the settlement displacement of the inner wall of the tunnel in real time, through the crack monitoring module, deformation monitoring module, vibration measurement module, stress acquisition module, and vertical displacement monitoring module to monitor the tunnel in real time. Vibration stress, vertical displacement and other data, the monitored data is modeled into a tunnel model through the 3D GIS model using vectorization processing, and includes the coordinate position and time stamp, and the collected data variables are made into a broken line statistical chart through the comparison module, which is displayed in the In the coordinates corresponding to the tunnel model, the operator can know the specific position and time data in the tunnel by observing the broken line statistics in the corresponding coordinates in the tunnel model, which is convenient for real-time investigation of defects in the tunnel, which is convenient, fast and efficient
