An apparatus (30) for reinforcing an external surface of a stationary vertical column (20) with a reinforcing material (61) includes a supply (60) of the reinforcing material (61) and a guide (62) that directs the reinforcing material (61) from the supply (60) onto the stationary vertical column (20). A winding device (30) moves the guide (62) in a spiral pattern relative to the stationary vertical column (20), to wind spiral layers of the reinforcing material (61) onto the vertical column (20). The winding device (30) is provided as a multipart structure that may be assembled around the vertical column (20) and later disassembled to permit removal from around the vertical column (20). In one approach, the reinforcing material (61) is tows of a curable composite material that are wound onto the vertical column (20) and later cured in place after the winding device (30) is removed.

La présente invention concerne un dispositif (30) permettant de consolider à l'aide d'un matériau de consolidation (61) la surface externe d'un pilier vertical fixe (20) et constitué d'une source d'alimentation (60) en matériau de consolidation (61) et d'un guide (62) qui dirige le matériau de consolidation (61) de la source d'alimentation (60) vers le pilier vertical fixe (20). Un enrouleur (30) déplace le guide (62) selon un mouvement de spirale autour du pilier vertical fixe (20), enroulant ainsi sur le pilier vertical (20) des couches spiralées de matériau de consolidation (61). L'enrouleur (30) est réalisé en une structure à plusieurs pièces qui s'assemble autour du pilier vertical (20) puis se démonte pour être retiré du pilier vertical (20). Selon une réalisation, le matériau de consolidation (61) est constitué de filaments de substance composite durcissable enroulés autour du pilier vertical (20) puis durcis sur place une fois que l'enrouleur (30) a été retiré.
