IRRIGATION PIPELINE Russian patent published in 2007 - IPC A01G25/06 

FIELD: agricultural engineering, in particular, furrow irrigation of root crops.

SUBSTANCE: irrigation pipeline has underground distribution pipeline with branch pipes-water outlets equipped with elastic perforated pipes joined at their entire length with flexible linear spiral member. Connection of perforated pipes with branch pipes-water outlets is made in the form of movable heads provided with spring-loaded two-position valve and projections insertable into spiral slots formed on internal surface of branch pipes-water outlets. Irrigation pipeline of such construction enables free passage of irrigation equipment along furrows during inter-irrigation period.
