Possibility of facing the upper storage reservoirs of pumped-storage stations with polymer film materials

Abstract

1. Watertight film materials can be used for facing the upper reservoirs of pumped-storage stations, the use of which is expedient not only on the slopes of the dike, but also over the entire area of the reservoir. 2. The main conditions for the successful introduction of film facings on the upper reservoirs of pumped-storage stations are the provision of stability of the faced slopes of the dikes and the development of technological schemes of construction works minimizing the danger of damaging the film. 3. Watertight film structures made in the manner of inclined membranes can be recommended for dikes, and the technological schemes of placing the watertight film elements both on the slopes of the dikes and over the entire area should be planned without travel of the construction mechanisms on the protective layer, by using mechanisms of the elevating-grader type.
