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

FIELD: irrigation systems.

SUBSTANCE: method consists in pre-dividing the territory of reclaimed lands into irrigated areas along furrows, marking the place for laying a flexible pipeline and cutting irrigation furrows, making drainage mattresses, developing irrigation furrows by size and slope for laying drainage mattresses. Drainage mattresses are laid in the irrigation furrows along the entire length, which consist of perforated polymer pipes with stiffeners and geomats wrapped around the pipes in two or three layers. Tubular drainage mattresses with stiffeners are made 2.0-2.5 m long and wrapped around in a mesh shell, laid along the slope of each furrow in one row so that the perforated drainage pipe of one mattress enters the pipe of the next mattress by 1-1, 5 cm. The furrows themselves are covered with levelling vegetation soil 8-12 cm thick on top of the drainage mattresses. Perforated pipes are made closed at the outlet, and the entrance part of each furrow with a drainage mattress is left 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.
