FIELD: agricultural engineering, in particular, irrigation equipment mounted on multiple-tower rolled pipelines.

SUBSTANCE: sprinkler machine has rolled pressure pipeline with sprinkler units and wheeled supports. One of wheeled supports is made as drive support equipped with hydraulic engine connected to control pipeline. Rolled pressure pipeline is composed of carrier carcass sections formed from oppositely arranged C-shaped bent profiles with flanged ends. Water supply pipe manufactured from high-pressure polyethylene is arranged inside carrier carcass cavity. Water supply pipe is composed of stepped-section pipes, said section discretely reducing in water supply direction. Pipe ends of each section are joined to one another through couplings. Adjacent carrier carcasses of rolled pressure pipeline are connected by means of fastening members through spacer bushings.

EFFECT: enhanced reliability in operation, simplified construction and improved quality of irrigation.
