    STUDY ON GROUTING PLUGGING TECHNOLOGY OF GUSHING WATER IN KARST PIPELINE

    • 摘要: 富水岩溶区基坑开挖过程中,岩溶管道涌水突泥严重影响基坑正常施工,文章依据贵阳地铁2号线延安路站深基坑岩溶涌水处治工程实例,对岩溶管道涌水注浆封堵技术进行了研究。针对涌水处治过程中出现的岩溶管道涌水情况,在充分了解岩溶涌水区域水文地质特征的基础上,采用探注结合方式,通过选择适当的注浆材料和配套工艺对涌水实现封堵。在实际的注浆工作中,总结了前期注浆的失败经验,对地下水的来源和通道进行深入分析,在此基础上及时调整注浆设计和实施方案,最终通过钻进辅助注浆孔,寻找岩溶地下水联系通道的方式进行双液注浆实现了成功的堵水。注浆过程控制及方案调整对类似基坑工程的岩溶管道涌水封堵具有借鉴意义。

       

      Abstract: In the process of excavation of the karst area, the karst pipeline flooding muddy mud seriously affected the normal construction of the foundation pit. According to the example of the karst gushing water treatment project in the deep foundation pit of Yan'an Road, Guiyang Metro Line 2,technology has been studied. Based on the understanding of the hydrogeological characteristics of the karst gushing water area, the plugging method is adopted to select the appropriate grouting material and matching technology to realize the sealing of the gushing water. In the actual grouting work, summed up the experience of the previous grouting failure, the groundwater source and channel for in-depth analysis, on this basis to adjust the grouting design and implementation of the program, and finally through the drilling of auxiliary grouting hole, Karst groundwater connection channel for double liquid grouting to achieve a successful water shutoff. Grouting process control and scheme adjustment have reference for karst pipeline gushing in similar foundation pit engineering.
