引江济淮9座船闸全面建成

Core Viewpoint - The completion of the Shushan double-line ship lock project marks a significant milestone in the water transport infrastructure of Anhui Province, enhancing the capacity and efficiency of the Jiang-Huai Canal [3][4]. Group 1: Project Completion and Significance - The Shushan double-line ship lock has successfully passed acceptance inspection and is ready for trial operation, completing all nine locks of the Jiang-Huai project [3]. - This project is crucial as it addresses the highest technical difficulties and the largest water level drop along the Jiang-Huai Canal, effectively doubling the traffic capacity at the Shushan hub [4][5]. Group 2: Technical Challenges and Innovations - The construction faced significant geological challenges, including expansive soil and disintegrating rock, which had previously hindered similar projects [5]. - Innovative solutions were implemented, such as using modified soil for stabilization and advanced temperature control methods during concrete pouring [5][6]. Group 3: Environmental and Economic Impact - The Shushan double-line ship lock features a unique "provincial water lock" system that allows for water recycling between the two locks, significantly reducing water consumption [6][7]. - The project is expected to boost the annual cargo volume of the Jiang-Huai Canal to 200 million tons by 2030, representing 28% of the province's total water transport, and saving approximately 6 billion yuan in logistics costs annually [8].
