FIELD: various technological processes; floating facilities.

SUBSTANCE: invention relates to a method of connecting monoblocks from spheroplastic into composite blocks of buoyancy. Method, in which prefabricated monoblocks from spheroplastic of simple shape in the form of parallelepipeds, are folded as “brickwork” row by row, with the exception of monoblocks forming the outer surface, which repeats contours of the outer housing of the apparatus. Further, separate monoblocks of a row of monoblocks from spheroplastic are sequentially glued to each other, and in case of presence of the previous row — also to monoblocks of the previous row, using an adhesive composition. In order to fix separately manufactured monoblocks relative to each other during their gluing, recesses are made on their end outer surfaces, wherein said recesses are located strictly opposite each other relative to contact surface of adjacent monoblocks. Simultaneously with gluing separate monoblocks, they are fixed to each other by installing planks from polymer composite material in recesses of a separate monoblock of a row and recesses of adjacent monoblocks located strictly opposite to each other relative to the contact surface of neighbouring monoblocks. Operations of installation, gluing and fixation of monoblocks are similarly repeated for the next rows of monoblocks. For gluing separately made monoblocks, an adhesive composition based on spheroplastic is used, from which the monoblocks are made, wherein the composite buoyancy block assembled from the monoblocks is subjected to a curing step of the adhesive composition.

EFFECT: improved manufacturability and reduced labour intensity of making composite blocks of buoyancy, increased strength of connection between monoblocks from spheroplastic during their assembly into composite blocks with preservation of water resistance.
