The invention discloses a high-speed railway tunnel convergence automatic detection device and detection method, comprising: a laser target, a power supply module, a cabinet, a laser sensor, an inclination sensor, a communication module and a server; the cabinet is fixed on the inner wall of the tunnel, and the laser target is fixed on the On the inner wall of the tunnel, the laser sensor is fixed in the cabinet, the laser sensor is fixedly connected to the inclination sensor, the laser sensor, the inclination sensor and the communication module are respectively connected to the power module, the laser sensor and the inclination sensor are respectively connected to the communication module, and the communication module communicates with the server , the communication module transmits the distance measured by the laser sensor and the deflection angle measured by the inclination sensor to the server, and the server obtains the tunnel convergence value according to the distance and deflection angle. This high-speed railway tunnel convergence automatic detection device realizes real-time displacement and convergence of high-speed railway tunnels , rapid and long-term monitoring.
Description
Technical field [0001] The invention relates to the technical field of tunnel engineering measurement, in particular to an automatic detection device and a detection method for the convergence of a high-speed railway tunnel. Background technique [0002] In the process of tunnel construction and operation and maintenance, through the measurement of the change in the clearance size around the tunnel, that is, the measurement of the convergent displacement around the tunnel, the stability of the surrounding rock or structure of the tunnel can be judged intuitively and clearly. Therefore, the convergent displacement is the key to tunnel monitoring. Routine monitoring items. [0003] Convergence detection of high-speed railway tunnels currently mainly uses manual methods or vehicle-mounted methods, using tools such as total stations, laser sensors, CCD cameras, etc., to monitor the convergence of the tunnel section, but its efficiency is low, the cycle is long, and the delay is large. ...
