平陆运河枢纽工程船闸主体混凝土浇筑完成 19座跨运河桥梁建成

Core Viewpoint - The construction of the Pinglu Canal is progressing rapidly, with over 15,000 workers dedicated to achieving the navigation goal by 2026, having completed significant milestones in excavation and concrete pouring [1][3]. Group 1: Construction Progress - The Pinglu Canal has completed a total earthwork excavation of 306 million cubic meters and poured 5.846 million cubic meters of concrete for the lock structure, with approximately 115 kilometers of the waterway in basic construction [1][3]. - As of November 30, 2024, the Ma Dao hub achieved a record daily concrete production and pouring volume of 16,409 cubic meters, setting a world record for similar single-unit projects [3]. Group 2: Engineering Challenges - The construction of the Ma Dao, Qi Shi, and Youth hubs involves complex processes such as deep foundation excavation, concrete pouring for various structures, and the construction of large water pools and drainage gates, facing challenges like large single pour volumes and high temperature control difficulties [3][4]. Group 3: Management and Technology - The construction management team has implemented a scientific approach to scheduling, resource allocation, and safety control, establishing Asia's largest smart mixing plant to support large-scale continuous construction [4]. - The team has developed intelligent temperature control technology for large volume concrete, ensuring precise management throughout the production, transportation, pouring, and curing processes [4]. Group 4: Infrastructure Development - On New Year's Day, four bridges including the Jinhaiwan Bridge and Wanshengtang Bridge were completed and opened to traffic, enhancing transportation efficiency and improving the quality of life for local residents [6]. - The next phase of the Pinglu Canal hub project will focus on the installation of gates, debugging of electromechanical equipment, and construction of auxiliary projects to ensure high-quality and efficient completion [6].
