FIELD: construction.
SUBSTANCE: first damages are sealed in hydraulic engineering under water surface by isolation of a damaged section in a hydraulic engineering structure from water access. Sealing is carried out using a sealing cement and sand mortar. The mortar is loaded into elastic water impermeable reservoirs, isolating from access of water and air. Reservoirs are laid from a barge with a grab to the damaged section of the hydraulic engineering structure. Further reservoirs are compacted with the grab grip until complete filling of the damaged section.
EFFECT: reduced cost of works performance, reduced labour intensiveness and higher efficiency.
