复杂地质条件下福城工作井渗水处理与监测分析

Key Points

• This research aims to address water leakage issues in the Fucheng working well under complex geological conditions.
• Introduced the design overview of the well enclosure structure, including diaphragm walls and surrounding high-pressure jet grouting piles.
• Detailed the progression of the leakage event and subsequent remediation measures such as pumping, pressure grouting, and sealing efforts.
• Conducted in-depth analysis of leakage causes and proposed follow-up measures, emphasizing enhanced monitoring and water reduction tests.
• Successfully implemented measures led to the complete sealing of the leakage issue, improving well integrity.
• Identified contributing factors to leakage including surrounding groundwater bypass and construction flaws in slurry wall.
• Outlined lessons learned for similar engineering projects based on sealing experience.
