摘要
针对九景衢铁路金盘一号隧道在开挖过程中遇到的涌、渗水情况,研究提出了"洞外膏浆灌注联合洞内化学灌浆"的综合堵漏处理技术,成功解决了该隧道内的涌水及渗水问题,保证了混凝土衬砌的顺利施工。经过一年多的运行检验,处理段混凝土顶拱及洞壁均未出现渗水,达到了预期治理目的。
The article mainly discussed the cement paste slurry and the chemical grouting technology treatment for Jinpan tunnel leakage of Jiujingqu railway. The leakage and seepage has been successfully resolved which ensured the concrete construction. After more than one year of operation and inspection, no seepage was found in arch crown and wall of the tunnel, and achieved the expected treatment target.
