FIELD: agriculture.
SUBSTANCE: irrigating pipeline includes holes. The pipeline wall, at least in area of each hole, is arranged as multilayer. At least, one of the upper layer and the lower layer of the pipeline wall is made of a water-repellent material. The inner layer of the pipeline wall is made of the transparent material. The hole is defined by the cut surface in the pipeline wall. The specified surface of cut in the pipeline wall includes a tight coating, which coats at least the inner layer. The method to form a hole in the irrigating pipeline wall includes formation of a hole in the pipeline wall and a tight coating of the specified cut surface, at least, in the field of the inner layer.
EFFECT: design and technology make it possible to increase reliability of the pipeline operation by prevention of possible leaks.
