Abstract
A method for assembling a corrugated double-walled pipe section from pipe segments, having the steps of: providing an inner wall segment which is curved in circumferential direction and straight in longitudinal direction, providing an outer wall segment which is curved in circumferential direction and corrugated in longitudinal direction, connecting the inner wall segment to the concave side of said corrugated outer wall segment, providing a longitudinal profile at the longitudinally extending edges of the wall segment so as to provide a pipe segment, and connecting the adjoining longitudinal profiles of at least two of the pipe segments to each other.

A method for assembling a corrugated double-walled pipe section from pipe segments, comprising the steps of:
- providing an inner wall segment which is curved in circumferential direction and straight in longitudinal direction,
- providing an outer wall segment which is curved in circumferential direction and corrugated in longitudinal direction, said outer wall segment defining circumferentially extending channels,
- providing each circumferential end of the corrugated wall segment with a slanting surface,
- connecting said inner wall segment to the concave side of said corrugated outer wall segment,
- providing a longitudinal profile at the longitudinally extending edges of said wall segments so as to provide a pipe segment,
- forming a longitudinally extending channel in each longitudinal profile,
- connecting the adjoining longitudinal profiles of at least two of said pipe segments to each other, and
- making the circumferentially extending channels emanate into the longitudinally extending channels.
