FIELD: agriculture.

SUBSTANCE: sprinkling machine contains self-propelled trucks, a water supply pipeline, jibs and guy stretchings. The pipeline is located on the trucks along an arc. The pipeline is made of separate steel pipes with sprinklers. The pipes are made in the form of a thin-walled housing. The housing consists of a cover and a base. Flanges are formed by the outer and inner parts. The outer and inner parts are filled with polyurethane foam and are permanently connected to the base and the cover of the cover. A water-conducting polymeric pipe is installed in the housing. The pipe is located in the cutouts of the inner transverse partitions of the housing. The centres of the partition cutout circumferences are located along an arc. The space between the partitions is filled with rigid polyurethane foam.

EFFECT: reducing the sprinkling machine weight, reducing the susceptibility to corrosion while maintaining the structure strength.
