The invention relates to a repair method which applies to a pylon having an H-shaped cross-section (1), in particular for supporting catenaries, having at least one embrittled portion. Two substantially box-shaped metal inserts (7b) are placed opposite one another on either side of the core of the H, as well as two metal plates on each wing (3a, 3b) of the H, and said two inserts (7b) and said two metal plates (9a, 9b) are simultaneously attached by means of at least of one strip of composite material (11) having a self-hardening resin matrix. |
