This paper introduces the construction method of filling, seepage and scour prevention construction of cofferdam on pebble stratum of mountain river in the middle and upper reaches of Qiantang River (Qujiang section). Adopting the high-jet seepage-proof wall for anti-seepage construction technology. During the construction process, the high-jet seepage-proof wall based on the selection of different process parameters for the test section construction, through the actual effect and continuous summary analysis, basically mastered a set of practical Reasonable construction methods, and achieved good anti-seepage effect for the main construction of the ship lock to provide a good dry construction environment.
