Core Insights - The main point of the article is the significant progress made in the construction of the Xiamen Tongxiang High-tech City PPP project, with the completion of the main structure of the first phase of the new housing project, marking a new stage in its development [1][2]. Group 1: Project Overview - The project is located in the core area of the Xiamen Tongxiang High-tech City development zone, covering a land area of 37,016 square meters and a total construction area of approximately 154,000 square meters [1]. - The construction includes 8 high-rise residential buildings, 3 single-story auxiliary buildings, and a two-level underground garage, with the tallest building reaching 32 stories and a maximum height of 97.65 meters [1]. Group 2: Challenges and Solutions - The project faced numerous challenges, including deep foundation pits, long anchor cable construction periods, multiple overlapping work areas, and complex construction environments, with the maximum excavation depth reaching 16.0 meters and a total foundation pit area of approximately 45,000 square meters [2]. - The construction team utilized innovative technologies and management optimizations to overcome these challenges, implementing a "pile + anchor + waterproof curtain" support scheme to address the difficulties of deep excavation and high water levels [2]. Group 3: Quality Control and Innovations - The project adopted a "first piece system" construction model to establish physical samples before starting various sub-projects, ensuring precise guidance for subsequent construction [3]. - Innovative integration of 3D modeling, virtual simulation, and dynamic handover techniques addressed traditional scaffolding construction challenges, leading to the award of the 2024 Excellent Technical Achievement by China Communications Construction Group [3]. Group 4: Impact and Significance - The completion of the first phase of the new housing project will enhance the functional layout of the area and promote the self-organization and self-circulation of the urban support system [3]. - The project is expected to significantly improve the living environment quality in the high-tech city area, facilitate industrial clustering, and accelerate the deep integration of "people, industry, and city" [3].
