深海管网项目全线贯通

Core Viewpoint - The successful completion of the Guangxi Deep Sea Pipeline Project, featuring the "Longteng" shield machine, highlights a significant advancement in underwater construction technology while balancing ecological protection and economic development [3] Group 1: Project Overview - The Guangxi Deep Sea Pipeline Project spans approximately 8 kilometers, with a 5-kilometer underwater shield section, marking it as the longest underwater shield tunnel pipeline project in China [3] - The "Longteng" shield machine has tunneled over 5,000 meters in nearly 11 months, ensuring the project meets its timeline [3] Group 2: Environmental Protection Measures - The project utilized a custom shield machine to navigate through a 600-meter-long ecologically sensitive mangrove area, maintaining surface subsidence within 0.8 millimeters, equivalent to the thickness of an ID card [3] - A fully enclosed mud circulation system was implemented, reducing carbon emissions by approximately 60% per kilometer of construction, effectively preventing chemical pollution to the mangrove root systems [3] Group 3: Economic Impact - The project addresses the daily wastewater treatment challenge of 100,000 tons from over 150 enterprises in the coastal industrial zone, contributing to the establishment of a trillion-level coastal industrial cluster [3] - The successful integration of economic development and ecological protection demonstrates a model for future coastal engineering projects [3]
