高压摆喷灌浆技术在水库除险加固工程中的应用

摘要

Through summing up the design and construction technique for the cutoff wall formed with high-pressure swingjet grouting in the project of reservoir＇ s stabilization for dangerous release, the seepage controlling technique of high-pressure swing-jet grouting is discussed in detail, including such aspets as main construction technology, technical points, quality controlling and treatment measures for special conditions in construction. Through the application in the project of Baijiayao Reservoir＇s stabilization for dangerous release in Baoji City, it is showed that the technology of high-pressure swing-jet grouting has such advantages as good effect of seepage controlling, smaller construction platform, moderate cost and so on.%通过对水库除险加固工程中高压摆喷灌浆防渗墙工程设计及施工技术成功经验的总结，论述了高压摆喷灌浆防渗技术的主要施工工艺、技术要点、质量控制以及施工过程中应对特殊情况的处理措施。通过在宝鸡市白家窑水库除险加固工程中的实践应用表明，该技术具有防渗处理效果较好、要求施工平台宽度较小、造价适中等优越性。
