The present invention relates to a cable protection device in a common duct for facilitating maintenance. The purpose of the present invention is to maintain a cable wired inside the common duct to be in a wiring state even through there is the deformation and movement of the common duct due to earth pressure and ground subsidence and to facilitate the wiring and maintenance of the cable. The cable protection device comprises a tray fixing steel bar (20) which is buried in a common duct (2) to protrude toward inside the common duct; a support steel bar (3) which is buried in the common duct to protrude toward inside the common duct at the upper part of the tray fixing steel bar; a plurality of cable trays (10) which is a plate and has a mounting groove (11), at the upper surface, in which a cable (1) is arranged and a steel bar groove (12), at the bottom, in which the fixing steel bar is arranged and is supported by the tray fixing steel bar through the steel bar groove; and a cover (40) which is a plate with a steel bar hole, at the upper and lower parts through which the fixing steel bar and the support steel bar pass, is arranged inside of the cable formed on the cable tray, and covers inside the cable as the end part through which the fixing steel bar and the support steel bar pass is coupled to a nut. |
