三亚机场三期T3航站楼刷新建设纪录 智能技术打造“钢铁凤凰”

Core Viewpoint - The completion of the T3 terminal at Sanya Phoenix International Airport marks a significant advancement in the construction of key transportation hubs in Hainan Free Trade Port, utilizing advanced smart construction technologies to achieve record construction speed [1]. Group 1: Project Overview - The T3 terminal was constructed in just 18 months, setting a record for the fastest completion of a terminal of its size in China [1]. - The terminal features a unique "Phoenix spreading its wings" design, with a total roof area of approximately 35,000 square meters and a steel usage exceeding 5,000 tons [1]. - The project is designed to accommodate an annual passenger throughput of 18 million [3]. Group 2: Technological Innovations - The construction team employed innovative smart technologies, including 5G, BIM (Building Information Modeling), and big data, to overcome significant engineering challenges [1][2]. - The roof structure was divided into 15 construction zones, utilizing "super-large hydraulic synchronous lifting technology" to enhance safety and efficiency [2]. - Real-time data transmission from 56 high-definition observation points and intelligent sensors ensured precise control during the lifting process [2]. Group 3: Efficiency and Safety Improvements - The use of smart tower cranes has increased operational efficiency by nearly 15% and allows for rapid automated descent during adverse weather conditions [3]. - The implementation of 3D laser scanning technology during the interior decoration phase has significantly reduced measurement time and improved accuracy, with errors controlled within 3 millimeters [3]. - The project exemplifies the scalable application of smart construction technologies, providing a model for large infrastructure projects [3].
