FIELD: hydraulic engineering, particularly for dam building in severe climate regions.
SUBSTANCE: method for grouting dam including top column and bottom wedge with arranging cemented joint in-between involves opening joint between top column and bottom wedge by creating temperature difference on upper and lower edges of top column due to intensive freezing concrete at upper edge of top column which results in upper column rotation towards upper dam edge and in joint opening; grouting the opened joint. Temperature difference on upper and lower edges column is 15 - 45 C.
EFFECT: promotion of joint grouting, enhanced technological effectiveness of cementing works.
