FIELD: construction.
SUBSTANCE: device comprises a block of one and more bent pipelines joined to each other sides and mounted in one block. The block is fixed on the way of a flow of coastal streams to change direction of some water flows, their increased speed and introduction of these flows into a water area of bays and gulfs. Each pipeline is arranged as bent at the angle from 45° to 170° with a pitch of helical lines varying along the pipeline diametre along the outer diametre and with curvilinear helical surface along the inner perimetre in the form of pockets of curvilinear shape.
EFFECT: invention provides for discharge of dirt into open sea due to development of streams in water areas of bays and gulfs.
