METHOD FOR RECONSTRUCTING A DRAINAGE NETWORK Russian patent published in 2017 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used for reconstruction of outmoded and obsolete drainage network consisting of open conductive channel with entering drains. Method for drainage network reconstruction includes cleaning the channel, washing the drains, placing it into a closed pipeline and installing sprinklers. Before cleaning the channel the top sections of the drains are connected to an source collector, its depth of laying is determined using the maximum mark of level of sources of drains, sprinklers are installed with reference to the source collector and drains are washed; after cleaning has been completed, a mouth collector are used to connect mouth drains and a straight pipeline is placed into the channel at its minimum level mark; it is then connected to the mouth collector at this mark and is additionally connected with the source collector; then the channel is filled with soil. Additionally, the straight pipeline is communicated with the surface of the field by means of water intake wells.

EFFECT: invention makes it possible to reconstruct the existing drying network into a double-acting irrigation system providing additional water drainage in the pre-sowing period, water accumulation during snow melt and precipitation, use of water in the dry period and as a result creating optimal conditions for growing crops.
