FIELD: ecology.;SUBSTANCE: method comprises the construction of the dam in which body the pipe culverts are placed inclined to the horizon in the direction of the water course, which inlet pipes are mounted at an angle to the river bed, and the dredging in front of the dam in the form of water-settling pit. In the water track downstream from a potential source of negative impact a permanent waterlock is created. At the bend of the pipe culvert above the dam level a plunger-valve is mounted, which cross section is 10-15% of the pipe cross-section. The inlet of the pipe is protected by the filter and the outlet - by a grid. At the outlet end an antierosion tray is placed, equipped with a small spring-board. The dimensions of the pit is calculated considering the time of layering of water-oil emulsion according to the formula: where L is length of the pit, m; Q3 is water flow in a water-settling pit, m3/sec, Q3=Q1; Q1 is water flow in the water course, m3/sec; F3 is the cross section of the water-settling pit, m2; t is time of layering of water-oil emulsion, sec; a3 is the width of the pit bottom, m; c3 is the pit width by the water edge, m; H is the dam height, m; h1≥0.5 is dam height above the maximum water level in the pit, m; hp=H-h1 is the pit depth, m. The protective waterwork, resulting in the process of implementation of the method comprises the dam with the pipe culverts placed in its body and the plunger-valves mounted on them from the side of the water inflow and a water-settling pit in front of the dam for collecting water with waterproof walls. At the outlet end of the pipe an antierosion tray is placed equipped with a small spring-board. The upper end of the plunger-valve is made bent down and is located on a bend of the pipe above the level of the dam. The inlet opening of the pipe is equipped with an inlet pipe which lower diameter is 150-200 % of the pipe cross-section. On the inlet opening of the pipe the filter is installed, made in the form of a removable convex grid coarse-meshed dome, and the outlet opening of the pipe is protected by the grid. The grid mesh size of the outlet opening is made greater than the mesh size of the grid filter of the inlet opening.;EFFECT: increased reliability and efficiency of protection of hydrological net from extreme oil pollution in emergency situations in the pipeline transport.;2 cl, 1 dwg
