LOW-PRESSURE DRIP IRRIGATION NETWORK FOR WATERING SLOPE LANDS Russian patent published in 2019 - IPC A01G25/00 

FIELD: land reclamation.

SUBSTANCE: invention relates to the field of complex reclamation of agrolandscape on slopes of ravine and will find application in irrigation of shrub plantations of fruit and berry use, as well as flower and other plants in places of use of sections of terraces. Low-pressure network includes distributing pipeline (2), to which watering pipelines (3) with drip water outlets (11) and bypass device (25) at the end are connected through pressure regulator. Each irrigation pipeline (3) is suspended with possibility of movement in horizontal plane between posts (19) with a positive slope. Head section of this pipeline is fixed on first post (19). End section is equipped with post (19) fixed to the end of the irrigation pipeline with a bypass device in the form of branch pipe (25) and a flexible coupling. In the beginning, irrigation pipeline (3) is equipped with an adjustable ball valve (5) and soothing container (9) in the form of a cylinder from a transparent plastic material of high strength. Inside container (9) in its lower part inlet pipe is fixed and valve stroke limiter is introduced. Limiter is made in the form of a plug with a shank, with a return tension spring fixed on it. Spring fixes valve with limit stop. In addition, irrigation pipeline (3) is additionally equipped with pressure gage (6), standard plastic filter (7) with cylindrical grid and counter (8). Counter is made in the form of water flow measurement unit. Irrigation pipeline (3) is divided in length into separate sections taking into account differences with respect to ground surface, with hydraulically connected bypass devices and terraces of plantations. Bypass devices are made in the form of flexible inserts of branch pipes (22) fixed with yokes. Each section of pipeline (3) with positive slope is suspended by means of clamping clamp (20) with locking screw (21) and fixed to stands (19). End section of each irrigation section of pipeline (3) at the drop point is equipped with an adjustable ball valve. Latter end section of pipeline section (3) with discharge device in form of branch pipe (25) is additionally connected with discharge ball valve (26) laid on the ground surface, and is equipped with jet damper (27).

EFFECT: creation of optimal conditions for growth and development of shrub plantations, increased yield.
