Core Viewpoint - The inspection and maintenance of the Hukun High-speed Railway Xiangjiang Grand Bridge are crucial for ensuring the safety of high-speed rail and shipping, especially during the busy Spring Festival travel period. Group 1: Inspection Process - The Hukun High-speed Railway Xiangjiang Grand Bridge spans approximately 4500 meters and is a key navigational bridge on the Xiangjiang River [1] - The inspection team utilizes advanced technologies such as unmanned detection boats, drones, and underwater robots to conduct thorough checks of the bridge's external environment and structure [1][2] - The use of unmanned detection boats enhances safety and efficiency, allowing for high-precision measurements of the riverbed and reducing the risks associated with underwater operations [1] Group 2: Technological Advancements - Drones are employed to inspect hard-to-reach areas of the bridge, capturing detailed images of potential structural issues such as concrete cracks and rust on steel structures [2] - Underwater robots can operate in turbulent waters and reach depths of over 200 meters, effectively covering traditional inspection blind spots [2] - The overall inspection time has been significantly reduced from a full day to just two hours, while also providing more accurate data to ensure traffic safety during peak travel times [2]
