Core Insights - The article highlights the integration of advanced technologies such as underwater bridge inspection robots and drones in bridge maintenance to enhance safety and efficiency during the flood season [3][4]. Group 1: Technology Integration - The introduction of an underwater bridge inspection robot allows for efficient and precise detection of structural issues such as cracks, concrete spalling, and exposed rebar, with data being uploaded in real-time [3]. - Drones are utilized for aerial inspections, capturing detailed images of critical bridge components, and transmitting data to a digital management platform, covering a radius of 5 kilometers [3]. Group 2: Maintenance Strategy - The traditional method of bridge inspection relied heavily on manual labor and specialized vehicles, which was time-consuming and inefficient [4]. - The new approach combines water, land, and air resources for a comprehensive maintenance strategy, creating a "digital ledger" for each bridge that enhances decision-making in maintenance [4]. - The transportation department aims to establish a more intelligent flood prevention and maintenance detection system to strengthen the "smart maintenance defense line" [4].
