探访全球第一｜近4万根毫米级钢丝拉起世界第一高桥

Group 1 - The Guizhou Huajiang Gorge Bridge has received over 1.3 million visitors and more than 200,000 vehicles, contributing significantly to regional development [1] - The bridge's main cables are composed of nearly 40,000 steel wires, with a total length sufficient to wrap around the Earth's equator twice, showcasing its engineering prowess [1] - The main cables must meet high strength, excellent toughness, and strong corrosion resistance due to the complex environmental conditions of the gorge [2] Group 2 - The steel wires in the main cables have a strength of 2000 MPa, allowing each square millimeter to support approximately 0.2 tons, which is a 7.5% improvement over international standards [2] - The company has developed new zinc-aluminum-magnesium alloy coating technology and post-coating cooling processes, enhancing corrosion resistance by 2.5 times and securing nearly 10 invention patents [2] - A collaboration with Beijing Jiaotong University has led to the creation of a new method for installing fiber optic sensors within the main cables, enabling real-time monitoring and scientific maintenance of the bridge [3] Group 3 - The company is planning to establish a key laboratory for special metal wire materials in Guizhou Province to support the construction of more super-engineering projects with advanced core material technologies [4]
