Preventing accidents and reducing the consequences thereof are matters that have become more and more important as the volume of traffic increases in society. One way of reducing the consequences of accidents is to mount safety barriers along the roads to prevent cars from leaving the road or getting into the opposite roadway. The invention relates to a safety barrier of the type steel cable barrier, also called wire barrier. Prior-art steel cable barriers require extensive and time-consuming work for mounting. A barrier has two wire anchoring foundations (4) and a plurality of wire post foundations (5) of convrete which are to be buried. Digging work ghat may cause subsidence that must be repaired later. The invention discloses a steel cable barrier (1) which solves these problems. A steel cable barrier (1) according to the invention comprising wires (2), wire posts (3) and a wire anchor (7) comprising a ground anchoring means (41) with anchoring wings (43) which are pressed or driven down into the ground. The invention also relates to a method of mounting a steel cable barrier (1) by a wire anchor (7) being pressed or driven down into the ground.

La prévention des accidents et la réduction des conséquences de ceux-ci revêtent chaque jour plus d'importance, par suite de l'accroissement permanent du trafic. L'une des manières de réduire les conséquences de ces accidents consiste à monter des glissières de sécurité le long des routes, de façon à empêcher les voitures de quitter la route ou de passer sur la voie de roulement opposée. L'invention concerne une glissière de sécurité, du type à câbles d'acier, appelée également barrière de câbles métalliques. Les barrières de câbles métalliques actuelles nécessitent un important et long travail de montage, une barrière comprenant deux fondations d'ancrage des câbles ainsi que plusieurs fondations de poteaux (5) de câbles, en béton, à enfouir, le travail de creusement pouvant provoquer un affaissement qui doit être réparé ensuite. L'invention concerne une glissière à câbles d'acier (1) résolvant ces problèmes, et comprenant des câbles métalliques (2), des poteaux (3), ainsi qu'un ancrage de câbles métalliques (7) comportant des moyens d'ancrage (41) pourvus d'ailes d'ancrage (43), enfoncées dans le sol en y étant dirigées ou poussées. L'invention concerne également un procédé de montage d'une glissière à câbles d'acier (1) au moyen d'un ancrage (7) de câbles d'acier enfoncé dans le sol en y étant dirigé ou poussé.
