Abstract
Process for the manufacture of prestressed concrete pipes, characterized in that it comprises the following steps: manufacture of two or more sections of pipe, in which the prestressing wire is initially brought to the required tensile pressure, casting the concrete so that these tensioned wires are anchored in the concrete; positioning of the prestressed sectors thus obtained by forming the total tube, sewn from the prestressing wires protruding from the edges of each sector; and opening of the joints between sectors until the prestressing wires are sewn to the required tension, then concreting the joints and removing the opening system as soon as the concrete has hardened.
