四佛水库的土层结构使大坝渗流不稳定,严重威胁水库大坝的安全。利用高压灌浆技术对水库进行除险加固,对其主体工程防渗板墙设计采用折线连接,分两序孔进行施工,取得良好效果,故建议在更多的防渗工程中推广和使用该技术。文章结合四佛水库除险加固工程高压摆喷灌浆实例,探讨高压摆喷灌浆技术在施工过程中可能遇到的情况及处理方法。
The soil structure of the Four Buddha Reservoir makes the seepage of the dam unstable and seriously threatens the safety of the reservoir dam. Using high-pressure grouting technology to reinforce the reservoir for reinforcement, the main project of impervious wall design using a broken line connection, two holes in the construction, and achieved good results, it is proposed in more anti-seepage project to promote the use and use of the technology . Combining with the example of high-pressure swing grouting grouting in Si Fo reservoir reinforcement project, the paper probed into the possible conditions and handling methods of high-pressure swing grouting grouting in the construction process.
