FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering and can be used in construction of mooring structures in the Arctic, including cryolite zone. Frozen massif of the dock is limited by external reinforced concrete elements forming a retaining wall of the angle section, and a ground body made of soil filling internal space, enclosed reinforced concrete walls. At the stage of the soil filling device, it is frozen in layers, including by means of a system of horizontally arranged cooling pipes, the ends of which are brought into cooling ventilation cavities in contact with side walls of the dock. Further, the frozen emollient massif is cooled annually during the whole operation period. System operates in the coldest winter period and switches off in the warm period of the year and in winter during the thaw, for which gate valves are provided. If necessary, the efficiency of the system can be amplified by fans.
EFFECT: technical result consists in improvement of reliability and operational safety of berth.
