Abstract

La présente invention concerne une installation de chemin de câble autoporteuse qui comprend : un tunnel souterrain enterré ; un cadre principal formé de façon à correspondre à la forme intérieure du tunnel souterrain, le cadre principal étant ajusté et installé à l'intérieur du tunnel souterrain ; une pluralité de cadres de support formés pour s'étendre horizontalement sur la surface interne du cadre principal ; une pluralité d'éléments d'accueil installés sur la partie supérieure des cadres de support respectifs pour accueillir un câble d'alimentation ; une pluralité d'unités évitant que le câble d'alimentation s'échappe en appuyant sur le câble d'alimentation au niveau de la partie supérieure des éléments d'accueil respectifs ; et un réseau formé horizontalement le long de la direction longitudinale du tunnel souterrain près de la partie inférieure interne du tunnel souterrain. La présente invention est avantageuse en ce que le cadre principal, auquel sont accouplés les éléments d'accueil permettant d'accueillir le câble d'alimentation et les cadres de support, est fabriqué avec une forme correspondant à la forme intérieure du tunnel souterrain et en ce qu'il est installé par l'ajustement du cadre principal sur l'intérieur du tunnel souterrain, ce qui permet de réduire la durée d'installation d'une conduite électrique souterraine et de raccourcir toute la durée de construction, puis d'empêcher l'apparition de fissures sur le tunnel souterrain, ce qui permet d'éviter que le tunnel souterrain soit endommagé.
