Abstract
Method for the manufacture of prestressed concrete tubular structures, by means of the use of cable-stayed wires and of a plurality of tubular concrete sections provided with a plurality of longitudinal holes located inside and surrounded by concrete in circumferentially distributed positions all around inside of the walls of each section, comprising the steps of: placing said end-to-end sections forming a series, with sealing means between the ends and with said holes of each section aligned and in communication with corresponding holes of the adjacent section; to thread a group of wires through each of said holes and to tie said wires under strong tension by forces applied to the ends thereof; and subjecting the series of sections to longitudinal compression, adhering the successive parts of the wires to each other and directly to the adjacent parts of the concrete in the holes by injection of a load or grouting under pressure through the interior and through the holes. And eliminating said forces after the said slurry has hardened and hardened; trusting in the successive to the adherence of the grout the mission to permanently maintain the wires under mechanical tension, sensibly to all along the holes, and the sections of concrete under permanent compression, end to end, submitting itself to strong compression the means of hermetic closing caught between ends of section.
