青岛地铁15号线建设新进展

Core Insights - The Qingdao Metro Line 15 project has achieved a significant breakthrough with the successful completion of the left line of the shield tunnel section at the Jihongtan vehicle depot [2] - The construction utilized a composite shield method over a length of approximately 1.3 kilometers, navigating complex urban infrastructure [2] Construction Details - The shield tunnel section runs along Xincheng Second Road, passing under multiple commercial buildings and factories, and crossing over the right line of the Tiannan section [2] - The tunnel depth ranges from 5.5 to 16.4 meters, primarily traversing highly weathered to moderately weathered andesite rock layers [2] - A pumping station constructed using the mining method is located at the YCRK0+965.000 mileage point [2] Project Management - The project faced complex construction conditions, but with strong support from local authorities and the Qingdao Metro Group, the construction team effectively organized and executed the project [2] - Real-time optimization of shield tunneling parameters and precise control of grouting processes were implemented, alongside automated monitoring systems to track ground and building deformations [2] - The project successfully maintained ground settlement within millimeter levels, achieving the goal of safe and precise tunnel completion [2] Future Plans - The Qingdao Metro Line 15 project team will continue to prioritize safety and quality while efficiently advancing subsequent construction phases to contribute to urban development [3]
