FIELD: construction.
SUBSTANCE: dam includes a concrete wall at the side of an upper reach arranged in parallel to the dam with an expansion joint between them, which expands from the dam foundation upwards. The concrete wall is made in the form of lining on a rock slope and in the base of the expansion joint, the cavity of which is filled with asphalt concrete.
EFFECT: higher tightness of coupling of a concrete dam at the side of an upper face with a rock base and in general reliability of dam operation under operation conditions.
