An Immersed Tube Tunnel Monitoring and Early Warning Device

Abstract

The invention relates to the technical field of tunnel monitoring, and discloses an immersed tube tunnel monitoring and early warning device, which includes a monitoring module, an analysis and processing module, and an early warning module. The monitoring module includes a plurality of first sensors, a plurality of second sensors and a temperature sensor. The sensor and the second sensor are respectively used to monitor the lateral differential displacement and the vertical differential displacement between two adjacent immersed tubes of the immersed tube tunnel, and the temperature sensor is used to monitor the temperature of the environment where the immersed tube tunnel is located; the analysis process The module is used to regularly calculate the average lateral difference displacement and the average vertical difference displacement within the preset time period according to the data sent by the monitoring module, and compare the average lateral difference displacement and the average vertical difference displacement with the corresponding preset displacement difference thresholds , determining whether to generate an early warning instruction according to the comparison result; the early warning module is used to execute the early warning instruction. The invention realizes the monitoring of horizontal displacement and vertical displacement between two adjacent immersed tubes of the immersed tube tunnel.

Description

technical field [0001] The invention relates to the field of tunnel structure health monitoring, in particular to an immersed tube tunnel monitoring and early warning device. Background technique [0002] Under the dual effects of the long-term natural environment and the use environment, horizontal and vertical displacements are prone to occur between two adjacent immersed tubes of the immersed tube tunnel, and these displacements are likely to affect the structural health of the immersed tube tunnel, which is not conducive to the normal operation of the tunnel.
