摘要
现有的管片堵漏技术为直接用快硬水泥浆封堵后,在其中埋入注胶管,后注入聚氨酯堵漏。该方法起效快速,但施工质量差,无法长时间抵御外部水压,后续维护成本高。文中介绍了一种盾构隧道联络通道洞门复合管片的堵漏修复技术,用于机械法施工的盾构隧道联络通道专用复合管片的修复,这种修复方法能够在狭小环境中精准定位管片渗流路径,缩小管片内覆钢板背部裂缝,且能够满足地铁隧道长时间运营的耐久性要求,能够为后续类似项目提供参考。
The existing pipe plugging technology is to directly seal with fast hardening cement slurry,embed a rubber injection pipe in it,and then inject polyurethane for plugging.This method works quickly,but the construction quality is poor and cannot withstand external water pressure for a long time,resulting in high maintenance costs.The article introduces a leakage sealing and repair technology for composite pipe segments at the entrance of shield tunnel connecting passages,which is used for the repair of special composite pipe segments for shield tunnel connecting passages in mechanical construction.This repair method can accurately locate the seepage path of the pipe segments in a narrow environment,reduce the cracks on the back of the steel plate inside the pipe segments,and meet the durability requirements of long-term operation of subway tunnels,which can provide reference for similar projects in the future.
