COMBINED IRRIGATION SYSTEM Russian patent published in 2017 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used when using lands dried by means of a closed drainage. Double-acting irrigation system comprises closed drains that are connected to collectors having with storage basins of drainage effluent. Each storage basin has a stationary sprinkler device that includes a power unit mounted on frame, water pump, compressor with controlled air supply and sprinkler machine consisting of a mixing chamber with a discharge head to the input of which a compressor is connected. Water pump is connected with a nozzle mounted at the outlet of mixing chamber to the discharge head installed with possibility of rotation in the horizontal plane and equipped with two pivotally connected diametrically directed spray nozzles. Mixing chamber in the area where air is supplied from the compressor can have pointed electrodes connected to a high-voltage source for enrichment of dispersed water with ozone. Such dispersion of water in a combination with possible enrichment of water with ozone considerably increases the oxidizing capacity of aerosol that enhances its destructive effect on pesticides and other contaminants contained in drainage water. Use of the proposed double-acting irrigation system eliminates the possibility of occurrence of moisture deficit on a field in hot vegetation period, while simultaneously preventing formation of run-off and destruction of soil structure, as well as reducing the content of irrigation water pollutants.

EFFECT: improved MOC is achieved by lack of driveways and platforms to accommodate irrigation equipment near wells on the field.
