FIELD: construction.
SUBSTANCE: SPB is used, where a set of caissons is arranged as capable of interaction with guides located along walls. At the same time caissons are submerged by means of displacement in guides with the help of crane equipment, and after SPB has been leveled along horizon, with the help of crane equipment in guides, caissons are mounted as tightly joined in vertical plane. Lowering caissons to the bottom, a section closed in plant is formed with their help at the water area bottom by means of its space limitation, and after works have been completed in this space with the help of crane equipment, caissons are lifted along specified guides and separated piece by piece.
EFFECT: reduced costs and improved reliability with realisation of proposed technology.
