Abstract: front page image
(EN)The invention relates to the field of bridges and more particularly to those that are relatively quickly deployable, as required in military applications. Prior art bridge reinforcement systems utilise a series of rigid reinforcement links which are suspended from the underside of the bridge to be reinforced. Such systems comprise a large number of individual tension elements all of which must be pre-installed and tensioned. This type of arrangement which is complex results in deployment of the reinforcement system being equipment and man intensive. Furthermore, this type of reinforcement system projects by as much as two metres from the underside of the bridge which means that it cannot be used where there are obstructions at this level. The invention proposes the use of a number of aramid fibre tendons which are attached to the underside of the bridge and held under tension.
(FR)L'invention concerne le domaine des ponts et notamment les ponts que l'on peut déployer relativement rapidement, comme cela est nécessaire dans des applications militaires. Les systèmes d'armature existants mettent en oeuvre une série de liaisons rigides d'armature qui sont suspendues à partir du côté inférieur du pont à renforcer. De tels systèmes comprennent un grand nombre d'éléments individuels tendeurs, lesquels doivent tous être préalablement installés et mis sous tension. Ce type d'agencement est complexe et son déploiement est lourd en matériel et en main d'oeuvre. En outre, ce type de système d'armature saille d'une distance de deux mètres, à partir du côté inférieur du pont, ce qui empêche son utilisation lorsqu'il existe des obstacles à ce niveau. L'invention propose l'utilisation d'un certain nombre de câbles en fibres aramides que l'on attache sur le côté inférieur du pont et que l'on maintient sous tension.
