The proposed sheath is for a structural cable () having a path between an upper anchorage () and a lower anchorage (). It comprises sheath segments () assembled along the path of the structural cable, at least one supporting rope () extending along the sheath segments and having an upper end connected to the construction work adjacent to the upper anchorage, and connectors () for connecting the sheath segments to the at least one supporting rope. The connectors () are configured to block relative upward movement of the supporting rope () with respect to the sheath segments () and to allow relative downward movement of the supporting rope with respect to the sheath segments.

Sheath for a structural cable of a construction work, methods of installation and maintenance

An anchoring device including two reinforcements for applying a hooping stress to a tubular structure, each of the reinforcements having a main binding portion which bears against the surface of the structure over 2 turns, a first end arranged at the end of a first end portion, and a second end arranged at the end of a second end portion. The anchoring device includes a spacer including a main body and two pairs of anchoring openings for the two ends of each reinforcement. The first and second end portions extend from a radial plane, where the reinforcements are tangential to the surface, then extend away from the surface from the radial plane as far as the anchoring openings so as not to exert a harmful point force on the structure.

Method and machine for reinforcing an embedded cylindrical pipe

A method for reinforcing a metal tubular structure () including the following steps: introducing inside the metal tubular structure (), a plurality of substantially linear elements () having a tensile strength higher than a predetermined value; and injecting a curable filling product inside the metal tubular structure, so that the curable filling product contacts an inner surface of the metal tubular structure () and coats the substantially linear elements () of said plurality of elements.

Method for reinforcing a metal tubular structure

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.

A composite structural reinforcement is realized within the pipe through in situ stratification of at least one band of reinforcement fibers and a resin matrix. The band is arranged according to a helicoidal path along the internal side of the pipe.

The structural cable () to be anchored, such as a main suspension cable or a stay cable, is made of a compact bundle of parallel metallic wires. The cable wires are distributed into seven-wire units () in a portion of the cable adjacent to an anchor block (), and these seven-wire units are individually anchored on the anchor block.

Method for anchoring parallel wire cables and suspension system for a construction work

A device for fixing together a construction element and a structural cable, the device has a rigid housing connected to the construction element and surrounding the cable, a wedging structure comprising at least one deformable material arranged between the cable and housing, and load transmitting means arranged to exert a longitudinal compressive force, parallel to the cable, on the wedging structure. The wedging structure is pressed against the cable and the housing under the action of the longitudinal compressive force, so as to offer resistance to movement of the housing and of the construction element parallel to the cable.
