Abstract

The invention relates to a triple-walled drainage pipe (1) made of plastic, usable as a multipurpose or part drainage pipe, a smooth-walled inner pipe (2) being surrounded by a corrugated pipe (3) and being welded to the valleys of corrugation (4) thereof and having slot-like perforations (8) for the passage of drainage liquid, and the corrugated pipe in turn being surrounded by an outer pipe (6) which, according to the invention, is pressed into the valleys of corrugation (4) and perforated only in the pipe vertex in the region of the perforations (8), but is smooth in the remaining pipe region. The addition of an outer pipe (6) provides improved rigidity and increases the vertex compression strength, while being simple and inexpensive to manufacture. <IMAGE>
