Abstract
A partial-seepage drainage pipe includes a wall surface of circular profile which is corrugated over the majority of the pipe circumference. Adjoining the circular wall surface is a base having a bottom surface and side wall segments. The pipe has a mating sleeve molded on in one piece at one end, which is adapted to receive the free end of a corrugated pipe segment and has slit-like water seepage openings in the corrugated wall surface. In order to attain a tight mating-sleeve connection, the bottom surface of the base and the corresponding bottom surface of the mating sleeve are embodied such that they arch in a slightly convex fashion.
