希尼尔水库帷幕灌浆防渗试验效果分析

Effect Analysis of Curtain Grouting Anti-seepage Test in Xinier Reservoir

新疆希尼尔水库坝基因部分坝段原防渗深度偏浅,坝基渗水严重,必须进行除险加固处理。针对水库坝基地层特点,为验证帷幕灌浆施工工艺在希尼尔水库地层中的实际防渗效果,先期进行帷幕灌浆试验,介绍帷幕灌浆试验灌浆孔、检查孔的方案设计、施工过程以及施工效果,并进行分析,可为希尼尔水库坝基防渗处理选择适合的防渗处理施工工艺提供详细的资料,其经验也可为今后类似工程提供参考。

The original anti-seepage depth of the dam gene part of the Xiner Reservoir in Xinjiang is shallow,and the dam foundation seepage is serious.It must be treated with danger removal and reinforcement.According to the characteristics of the reservoir dam base layer,in order to verify the actual prevention of the curtain grouting construction technology in the Xinier reservoir Seepage effect,preliminary curtain grouting test,introduction of curtain grouting test grouting hole,inspection hole plan design,construction process and construction effect,and analysis,can choose suitable anti-seepage treatment construction technology for Xinier Reservoir dam foundation anti-seepage treatment Provide detailed information,and its experience can also provide reference for similar projects in the future.
