FIELD: agriculture; irrigation system. ^ SUBSTANCE: invention relates to the irrigation system and can be used in surface irrigation of crops on the furrows, bands or checks as irrigation distribution or transported pipeline, and also with the possibility of combining the pipeline transporting and irrigated functions. The irrigation pipeline includes a flexible shell with the water outlet port located in even pitch on the surface, and a device for cutting off water outlet port along the outside of the flexible envelope and elastic elements that are made in the form of tight pockets with varying degrees of expansion by means of which the hose is omitted with perforation inside the pockets. The pockets are performed in the form of ring cameras installed in axial alignment with water outlet port of elastic material. ^ EFFECT: steady water supply into the furrows; improving of irrigation; stress concentration decreasing in the water outlet port; improving the efficiency of the pipeline. ^ 3 dwg |
