Application and analysis of curtain grouting in seepage prevention and reinforcement of masonry dam

Abstract

At present, the number of masonry dam in China is still relatively large. Due to various reasons, many of the dam body appears aging, degradation and other phenomena, and leakage is one of the common problems. Now grouting technology is the main technical means of anti-seepage treatment. Curtain grouting technology has wide adaptability to strata. With the gradual improvement of grouting technology, it has been widely applied in engineering and water conservancy projects. In order to ensure the safety of the dam and improve the grouting effect, this paper summarizes the rules of anti-seepage treatment based on the actual grouting treatment methods, and provides technical guidance for the anti-seepage treatment of other similar masonry dams.
