FIELD: agriculture.SUBSTANCE: drainage system comprises a collector 1 connected with the drains 2 entering into it, vertical tubes 3 and a device for flushing of sediments. The device for flushing is made of perforated pipes 4 in the form of air outlets 7 arranged inside the drains 2 attached to the upper part of the pipes above the bottom. The perforated pipe 4 by the metal barrel 6, placed in the tube 3 is connected to the pressure hose 8, which inlet is connected to the discharge pipe 9 with the valve 10 of the receiver 11. The receiver 11 is connected to the compressor 12 generating the compressed air. The compressor 12 is connected to the timing relay. The invention increases the transporting capacity of disturbance sediments and other compounds in the drain cavity and accelerates their removal into the open channel 17.EFFECT: increased efficiency of flushing and increased drainage term by air exposure to sediments.2 cl, 2 dwg |
