This study systematically analyzes the main environmental impact mechanisms of such projects from the perspectives of air quality deterioration, water pollution, noise and vibration disturbance, and solid waste generation. The findings reveal that the environmental impacts of municipal pipeline construction are characterized by periodicity, complexity, and cumulative effects. To mitigate these issues, a systematic set of countermeasures is proposed, covering environmental impact assessment during the pre-construction stage, pollution prevention and control during construction, and ecological restoration and supervision in the post-construction stage. Establishing a full-process and all-factor environmental management system can effectively reduce ecological disturbances, enhance environmental protection efficiency, and promote the coordinated development of urban construction and ecological sustainability. This research provides both theoretical reference and practical guidance for advancing green and low-carbon municipal engineering practices.</li></ul>/AE/paperinfo/62545.shtmlArchitectural Engineering /AE/paperinfo/62545.shtml2025-12<p class="abstract">Long-Distance Shield Tunneling Through Flexible Casings and Atmospheric Pressure Chamber Opening for Obstacle Removal in Urban Central Areas</p><ul><li>Pages 6-12</li><li>Author Yuwei S</li><li>Abstract In shield tunneling projects within urban central areas, shield machines increasingly encounter abandoned underground trenchless pipelines, posing a persistent and challenging obstacle to smooth construction progress. To address this issue, this paper proposes three core countermeasures: equipment modification, pre-grouting of casings, and forward-reverse flushing circulation technology. Additionally, to accommodate stoppage conditions during long-distance tunneling, intermediate reinforcement zones have been established to facilitate atmospheric-pressure chamber opening for obstacle removal. These measures have been successfully implemented and validated in the Section 2#–5# (a 3-km-long DN3500 shield tunnel) of the Longhua Wastewater Treatment Plant’s Initial Rainfall Storage Project in Xuhui District, Shanghai, demonstrating their feasibility and effectiveness, thereby offering valuable reference for similar engineering projects.</li></ul>/AE/paperinfo/62565.shtmlArchitectural Engineering /AE/paperinfo/62565.shtml
