主要以某小型水库的主坝维修加固工程为例,介绍在进行主坝帷幕灌浆施工中应当注意的问题。首先分析了本水库主坝的病害状况以及发生渗漏的主要原因,详细介绍了本次工程施工中主坝的防渗加固设计方案和具体的施工技术方法,并就施工成果进行了检验与分析,证明在本次及工程的主坝维修加固工程中,采用帷幕灌浆的施工技术方法取得了较好的加固效果,值得同类工程参考借鉴。
The main dam repair and reinforcement project of a small reservoir is taken as an example to introduce the problems that should be paid attention in the construction of the main dam curtain grouting. First of all, it analyzes the main dam’s disease condition and the main reason of seepage, introduces the seepage control design plan and concrete construction technology method of main dam in this project in detail, and tests and analyzes the construction results It proves that in this project and the main dam repair and reinforcement project, the curtain wall grouting construction technology has achieved good reinforcement effect, which is worthy of reference for similar projects.
