Abstract
In order to reinforce a cylindrical pipeline, in particular an underground water supply pipeline, prestressing reinforcements are placed and tensioned around it. In a zone where the pipeline has a radial projection, for example providing a manhole for access to the inside of the pipeline, the prestressing reinforcements are deflected to bypass the radial projection so that the reinforcements, located in the same layer on a side of the pipeline opposite the side having the projection, are distributed in a plurality of layers on this side having the protuberance.
