Abstract: Chemical grouting technique has been applied in China for more than 50 years, and Specification for Chemical Grouting Construction of Hydraulic Structures(DL/T 5406-2010), as the first specification for chemical grouting technology in China, has been enacted and implemented for about 7 years. We have been focusing on implementation of the specification, and collected some comments and suggestions by communicating with professionals, referring related articles, studying engineering cases and self-practicing. And we have put forward some correlated suggestions, such as modifying the specification title, adding the chapters on grouting experiments, etc. Through this paper, we attempt to exchange opinions with professionals to provide reference for revision of the specification.
