A protection installation structure of an underground power cable is provided to prevent the deformation of the underground power cable by accommodating the cable in a protection cover and filling mortar. A protection installation structure of an underground power cable includes the underground power cable, a protection cover(120), a coupling device(130), a support, and mortar(150). The underground power cable is a general cable having a core and a cover formed around the core. The protection cover(120) is made of deformable material such as polyethylene and has a cylindrical shape and mortar injection holes(121) formed at predetermined intervals. The coupling device(130) has a wire ring(131) integrated with a cut portion of the protection cover(120), a coupling step(133) installed at the other side of the cut portion of the protection cover(120) and having a through hole, and a coupling wire(135) coupled with the wire ring and having a screw hole(136) penetrating the coupling step(133) and fixed by a nut(137). The support(140) is installed on an inner bottom of the protection cover(120) to support the underground power cable. |
