Abstract

The invention discloses a high speed railway tunnel convergence automatic detection device and detection method. The device comprises a laser target, a power supply module, a cabinet, a laser sensor, a tilt angle sensor, a communication module and a server. The cabinet is fixed to the inner wall of a tunnel. The laser target is fixed to the inner wall of the tunnel. The laser sensor is fixed in the cabinet and is fixedly connected to the tilt angle sensor. The laser sensor, the tilt angle sensor, and the communication module are connected to the power supply module. Both the laser sensor and the tilt angle sensor are connected to the communication module which communicates with the server. The communication module sends the distance measured by the laser sensor and the deflection angle measured by the tilt angle sensor to the server. The server obtains a tunnel convergence value according to the distance and the deflection angle. According to the high speed railway tunnel convergence automatic detection device, the real-time rapid long-term monitoring of high speed railway tunnel displacement and convergence is realized.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering measurement, in particular to a high-speed railway tunnel convergence automatic detection device and detection method. 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 convergence displacement around the tunnel, the stability of the surrounding rock or structure of the tunnel can be clearly and intuitively judged. Therefore, the convergence displacement is an important aspect in tunnel monitoring. Routine monitoring items. [0003] Convergence detection of high-speed railway tunnels currently mainly adopts manual or vehicle-mounted methods, using tools such as total stations, laser sensors, and CCD cameras to monitor the convergence of tunnel sections, but its efficiency is low, the cycle is long, and the delay is large. It can...
