三亚国际免税城三期项目建设全面提速

Core Viewpoint - The construction of the Sanya International Duty-Free City Phase III project has accelerated, with the main structure fully capped and various construction processes advancing simultaneously towards a phased completion goal by 2026 [4][6]. Group 1: Project Overview - The total construction area of the Sanya International Duty-Free City Phase III project is 412,700 square meters, and it is a key project in Hainan Free Trade Port [4]. - The project aims to enhance the vacation and leisure experience in the Haitang Bay area, attracting foreign consumer spending and positioning Haitang Bay as a premier cultural and commercial tourism destination in Hainan [4]. Group 2: Technical Challenges and Innovations - The project faced significant challenges due to its coastal location, including strong water permeability of the soil and high corrosion potential, necessitating innovative solutions for anti-floating safety and corrosion resistance [4][5]. - A comprehensive anti-floating technology was developed, utilizing "anti-floating anchor rods and raft foundations," along with a 300mm adjustable drainage well to dynamically manage water levels [4]. - The concrete used in the project has achieved a sulfate resistance level of KS120, significantly enhancing its impermeability and durability, with both core technologies reaching international leading standards [5]. Group 3: Construction Techniques and Sustainability - The project features the country's first prefabricated underground commercial complex, with a single underground area of 196,000 square meters, employing seamless construction techniques to minimize post-pouring joints [6]. - It is set to become the first "zero-carbon" commercial complex in the country, integrating over 60,000 square meters of underwater photovoltaic panels and a flexible power distribution system, currently recognized as a green low-carbon demonstration project in Hainan [6]. - The construction team is increasing personnel to nearly 1,000 as the project enters a peak construction phase, emphasizing safety, quality, and progress [6].
