Core Viewpoint - The successful completion of the East China Sea Bridge pier scour protection project marks a new stage in China's offshore bridge pile foundation protection technology, providing a solid guarantee for the long-term operational safety of the bridge [1][5]. Group 1: Project Overview - The East China Sea Bridge, spanning approximately 32.5 kilometers, has 205 bridge pier foundations that required systematic protection against excessive scour [1][2]. - The project team overcame various technical challenges, including complex underwater geology and high-precision underwater filling, and developed specialized equipment for scour protection [1][3]. Group 2: Technical Innovations - The project involved extensive research on scour mechanisms, protection design, and specialized construction equipment, leading to innovative protection solutions such as "bagged gravel, bagged concrete, and edge soft fabric protection" [3][5]. - A new underwater monitoring system was developed to ensure precise placement of materials, reducing placement errors to within 10 centimeters and enhancing safety during operations [3][4]. Group 3: Project Achievements - The project was completed 25 days ahead of schedule, demonstrating efficient resource allocation and management [4]. - The successful implementation of the project has provided a replicable "Chinese solution" for coastal bridge scour protection, contributing to the development of a systematic technology framework [5][6]. Group 4: Future Prospects - The project team aims to promote successful experiences and apply related technologies in more coastal bridges, offshore wind power, and other marine engineering projects, driving equipment manufacturing and industry upgrades [6].

Core Viewpoint - The successful delivery of the 1300-ton full rotation crane ship "Tiejian Daqiao No. 2" marks a significant advancement in bridge construction capabilities in China, particularly for projects like the Qinglongmen Grand Bridge in Zhoushan, Zhejiang [1] Group 1: Company Developments - China Railway Construction Bridge Engineering Bureau Group has added a new asset to its fleet with the delivery of the "Tiejian Daqiao No. 2" [1] - The company now operates a total of "eight types and nine ships," including the 2500-ton straight arm crane ship "Tiejian Daqiao No. 1" and the 6000HP tugboat "Tiejian Daqiao Tug No. 1" [1]
