FIELD: construction.
SUBSTANCE: group of inventions relates to construction of underwater pipelines. In the method of connection of two sections of the underwater pipeline a telescopic sleeve (39), having the first connection head (40), is connected with the first end (35) of the first section (31) of the pipeline in the above-water position above the water reservoir (3). The first end (35) of the telescopic sleeve (39) and the first connection head (40) are installed into the first specified position at the bottom of the water reservoir (3). Further they connect the second connection head (42) with the second end (36) of the second section (32) of the pipeline in the above-water position above the water reservoir (3). The second end (36) and the second connection head (42) are installed into the second specified position near the first connection head (40) at the bottom of the water reservoir (3). Then they tightly connect the first and second connection heads (40, 42) in the underwater position in the water reservoir (3). Also the method is proposed for construction and repair of underwater pipelines, where the specified method of connection is used.
EFFECT: simplification and reduction of quantity of operations performed under water.
