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. The immersed tube tunnel monitoring and early warning device comprises a monitoring module, an analysis processing module and an early warning module, wherein the monitoring module comprises a plurality of first sensors, a plurality of second sensors and a temperature sensor, the first sensors and the second sensors are used for monitoring transverse differential displacement and vertical differential displacement between two adjacent immersed tubes of an immersed tube tunnel respectively, and the temperature sensor is used for monitoring the temperature of the environment where the immersed tube tunnel is located; the analysis processing module is used for periodically calculating average transverse differential displacement and average vertical differential displacement in a preset time period according to data sent by means of the monitoring module, comparing the average transverse differential displacement and the average vertical differential displacement with corresponding preset displacement difference thresholds respectively, and determining whether to generate an early warning instruction or not according to comparison results; and the early warning module is used for executing the early warning instruction. According to the immersed tube tunnel monitoring and early warning device, monitoring of horizontal displacement and vertical displacement between two adjacent immersed tubes of the immersed tube tunnel is realized.
