Seepage pipe for use in agricultural applications, has corrugation troughs provided between wave crests and comprising width in area of peripheral surfaces, where width of corrugation troughs is greater than width of peripheral surfaces

摘要

The pipe has an outer pipe (2') provided with wave crests (3), where the seepage pipe is designed as a composite tube. Outer peripheral surfaces (6) connect flanks (4, 5), and include a specific width. Corrugation troughs (8') are provided between the wave crests and include a width in an area of the peripheral surfaces. Water inlet openings (9') are slot-like formed in the corrugation troughs and comprise a width (a'). The width of the corrugation troughs is greater than the width of the peripheral surfaces.
