ANTI-EROSION RECLAIM SYSTEM OF SURFACE IRRIGATION BY FURROWS Russian patent published in 2023 - IPC A01G25/00 

FIELD: hydraulic engineering.

SUBSTANCE: reclamation system comprises a flexible wheeled pipeline with water outlets into irrigation furrows, a plot of irrigated land with irrigation furrows filled with mattresses. Tubular drainage mattresses are laid in the irrigation furrows, consisting of perforated polymer pipes with stiffeners and geomats wrapped around the pipes in two or three layers. Tubular drainage mattresses with stiffeners around are wrapped in a mesh shell. Drainage mattresses 2.0-2.5 m long are laid along the slope of each furrow in one row so that the drainage perforated pipe of one mattress enters the pipe of the next mattress by 1-1.5 cm. The furrows are covered with levelling vegetation soil with a thickness of 8-12 cm above the drainage mattresses. The perforated pipes are closed at the outlet, and the entrance part of each furrow with a drainage mattress remains open.

EFFECT: anti-erosion protection of the vegetative layer of the earth and creating favourable water conditions for the development of the root system of cultivated crops.
