摘要：
FIELD: agriculture.SUBSTANCE: device comprises a cantilever-type drop (1) connected by the outlet section to the top of a polyethylene well (2). Wells (6, 7) are installed along the length of the flow movement, close between which damping cushions (10, 11) are arranged, filled with a non-capillary filter material with a lowering in the form of a drainage cushion (16). The top of the damping pillows (10, 11) is covered with a water-permeable geotextile web (12, 13). In the lower part of the wells (2, 6) at the bottom, polyethylene discharge pipes (8, 9) with perforations in the upper part are placed. On the vertical walls of the wells (2, 6, 7) a grate (17) rests, made in the form of the axial jet line at maximum flow parameters and overlapping sequentially the damping pillows (10, 11) as well. The vertical walls of the wells (2, 6, 7) have slotted openings (20, 21, 22) along the flow. The upper part of the wall (3) of the well (2) and the end of the drop (1) section are equipped with visors (4,5), respectively. The well (7) bottom is connected to the discharge polyethylene pipe (23) on one level with the ravine bottom. The discharge polyethylene pipe (23) is made tapering from the beginning of the wall (19) of the well (7) to its open outlet. On the ravine bottom, a protective cushion (24) is made from a gravel-stone material or from a water-permeable geotextile web.EFFECT: increasing the device efficiency and durability, increasing the culvert capacity while reducing the clogging of the discharging end of the device.2 cl, 3 dwgИзобретение относится к области сельскохозяйственного машиностроения, в частности к устройству для борьбы с овражной эрозией.
