FIELD: agriculture; manufacturing technology.
SUBSTANCE: group of inventions relates to the field of irrigation pipes resistant to rodents, worms and insects. Device comprises at least one-layer flexible pipe (12), multiple outlets (26) and fine hydrophilic particles of silicon dioxide. Pipe (12) has inner section (14) and outer section (16) and is low-density polyethylene or flexible polyvinyl chloride (PVC). Plurality of outlets (26) pass through pipe (12) and they are spaced from each other similarly along length of pipe (12). Fine-dispersed hydrophilic particles of silicon dioxide are distributed in external section (16) of pipe (12), and not in internal section (14). Method of producing the sprinkler device comprises the following steps. At least one-layer flexible pipe (12) is extruded and outlets (26) are arranged in pipe (12) spaced apart along pipe (12) length.
EFFECT: providing surface hardness of irrigation pipe, providing resistance of pipe against rodents, worms and insects.
