An underground cable protection facility structure is provided to prevent an underground cable from being bent or twisted through an impact or ground subsidence by receiving the underground cable in a main body and a protection cover, and installing a fiber protection mat on an upper part. An upper end of a main body(120) is formed to have an incised cylindrical shape so that an underground cable(110) is received in an inside. A supporting bar is formed on an outer plane at a regular interval. A silicon(130) is filled between the underground cable(110) and the main body(120). A protection cover(140) is made of a changeable material and is formed to have an incised cylindrical shape so that the underground cable(110) is received in an inside. A connection plate has a locking bolt hole formed on both sides of an incision plane. A mortar insertion hole is formed on a side plane of the protection cover(140) at a regular interval. A mortar(150) is inserted into the mortar insertion hole of the protection cover, and is filled between the main body(120) and the protection cover(140). |
