FIELD: hydraulic engineering. SUBSTANCE: earth dam includes two side prisms - above 1 and down 2 dam, freezing columns 3 in foundation and ventilated space 5 formed at foundation with chute 6 made of monolithic concrete and with vertical side walls - above wall 7 and down wall 8 produced from prefabricated concrete built up to crest 9 of dam. In crest 9 space 5 is shut with dismountable members 10 and 11. Braces 12 are placed between walls 7 and 8 to form vertical openings above freezing columns 3. Above wall 7 consists of prefabricated plates 14 positioned in tiers. Each pair of plates 13 and 14 with braces 12 are fastened together as integral unit. Above wall 7 is made in the form of diaphragm with water-tight deformation-structural joints. EFFECT: reduced labour input and cost of construction of dam. 3 cl, 5 dwg
