Abstract: Piping in dykes can be caused by termite or other physical means, but technical personnel of water conservancy often confused them and called both as water conservancy piping in treatment. Based on a large number of observations, this paper discussed the distinction between the two types of piping, and different treatments that should be taken so as to prevent the collapse of dykes and dams. The termite-induced piping must be recognized as the biological occurrence and should be treated as such so that the dangerous situation of this piping can be avoided.

Key words: Termite, water conservancy, piping, earth dykes and dams
