Design and Construction of Plastic Concrete Impervious Wall in Dam Impervious Engineering
This paper takes Dawangtan Reservoir as an example to explore the design scheme and construction process of plastic concrete cutoff wall.The seepage flow of dam body and the height of the downstream seepage line of the dam are calculated by establishing the calculation model of the seepage wall on impervious foundation,and the parameters of the seepage wall thickness and depth are determined according to the calculation results.During the construction of plastic concrete cutoff wall,it is necessary to take quality control from the aspects of guide wall construction,groove division,mud preparation,groove cleaning and grouting,concrete placement,etc.,to ensure the anti-seepage effect of plastic concrete cutoff wall is up to standard.
