Abstract

The invention discloses a bridge cable corrosion all-weather online monitoring system and method, and the monitoring system comprises an integrated communication box and a monitoring integrated box, the monitoring integrated box is attached to a non-protective coating of a cable, and the integrated communication box is electrically connected with the monitoring integrated box for signal data collection. According to the invention, the corrosion rate state of the bridge cable can be monitored online in real time around the clock, and online acquisition of corrosion data in the service process of the bridge cable is realized.

Description

Technical field [0001] The invention belongs to the technical field of bridge corrosion protection, and more specifically relates to an all-weather online monitoring system and method for bridge cable corrosion. Background technique [0002] Cables (main cables, slings, stay cables) are the main stress-bearing components of suspension bridges / cable-stayed bridges, which bear all the loads of the bridge and are not easy to replace during the entire service life of the bridge. Under the atmospheric corrosive environment and load, as time goes by, the cable steel wire and its protective layer will inevitably produce corrosion and damage, shorten the service life of the bridge, and make it difficult to evaluate the safety and reliability of the bridge. Therefore, in order to ensure the structural safety of the bridge and prevent the occurrence of operational accidents, it is necessary to conduct online corrosion monitoring of the bridge cables to ensure the life-span safety of the br...
