FIELD: ecology.
SUBSTANCE: device comprises parallel shells 1 with a deck 20 and rails. Shells 1 are rigidly connected to each other by links 2 and have dead joints at both ends with fixators for creation of joined sections. Shells 1 are made with double walls as "pipe in pipe". Ends of shells 1 arranged at the side of floating dirt are made for a joined sealed connection. The connection in the assembled condition performs oscillating movements of section ends in space. The joined connection may have shape of various surfaces formed by rotation of convex curves around the horizontal axis, for instance, a circle, a Cassinian oval, an ellipse, cycloids. Links 2 are arranged as hollow and form a common volume with annular spaces of shells 1. In the annular spaces of shells 1 there are perforated pipes 34 for coolant supply. In the outer shells 1 there are nozzles for condensate drain from annular spaces. On the walls of outer shells 1 there are elements of fixation for lifting-lowering and mooring facilities. On the links of the shells 1 there are supports 8 with locks 9 for a rope 10 to pull and connect sections to each other. Inner shells 1 are made with stiffening ribs along the outer surface and are filled with the foamed solid material 3. In front of each section there is a header 14 for compressed air supply with mechanisms of header 14 submersion depth control. A shield 22 is installed on the wall of outer shells 1 between the header 14 and the shell 1. The shield 22 is equipped with mechanisms for control of its submersion under water level. Shields 22 are tightly connected to each other by locks 33. Perforated pipes 34 for coolant supply and headers 14 for air supply are connected accordingly with devices of coolant and air supply and are equipped with stop and control valves 35 and 15, accordingly.
EFFECT: quickness of obstructing device assembly and increased efficiency of oil spill containment.
