METHOD FOR ENLARGEMENT OF PORT MOORING PART Russian patent published in 2010 - IPC E02B3/06 B63B35/34 

FIELD: construction.

SUBSTANCE: invention is related to the field of construction, modernisation and reconstruction of port berths. Method is characterised with formation of mooring wall in the form of raft from several layers of multifunctionally used tight pipelines of various diametre, which are manufactured as helical-seamed and multilayer from composite set of materials. Wall is produced by two groups of technological tight pipelines laid on water surface in direction of its formation, which are joined to each other in each group with the help of coaxial stiff transverse ribs with development of two pontoons. Adjacent ends of ribs are joined to each other with the help of hinged joints, along axis of which the first of bearing pipelines is laid, and a pair of joined pipelines of the second layer is laid on top, and so on till rated level. Functional pipelines are laid onto the last horizontal layer of bearing pipelines, and composite elements of hatches and working surface fixed with tension to anchor ropes are mounted on functional pipelines. Internal volumes of upper - subsurface layer of pipes are equipped as functional premises: warehousing, technological, working premises. Railway track and motor road, which are joined to according ground transport network, are laid on surface of mooring wall.

EFFECT: invention makes it possible, as a result of elimination of earth works related to dredging, to reduce capital, material and financial costs in case of port mooring part enlargement, and also to reduce construction time.
