FIELD: construction.
SUBSTANCE: device includes a block of one and more pipelines bent at an angle and connected to each other with lateral sides and mounted in one block. The block is fixed on the way of flow of coastal currents to change direction of some part of water flows, to increase their speed and introduce these flows to a water area of bays and gulfs. Each pipeline is made in the form of a sector of a circular tubular cross-section, along the outer and the inner surfaces of which broken screw lines and screw surfaces are formed. A pipeline consists of sections, each of which is mounted of a strip bent to one side along straight lines arranged at an angle to the strip edges, with variable formation throughout the length of the strip of equilateral and isosceles triangles that are different as to sizes. Two similar equilateral triangles are located with their bases on two sides of the biggest equilateral triangle. On lateral sides of isosceles triangles there located are two similar equilateral triangles with two similar isosceles triangles located to them with their bases, on one of which an equilateral triangle is located. Sides of smaller equilateral triangles differ from sides of bigger equilateral triangles by one and the same linear value. Sections are connected to each other with free sides of the above triangles.
EFFECT: cleaning of stagnant and dirty waters of water areas of bays and gulfs owing to creating constant circulation of clean sea water inside them.
