The present invention relates to a tube for protecting an underground power distribution line, wherein a power distribution cable is protected from underground water and earth pressure and constructability is excellent while facilitating repair, maintenance and management via a simple structure. The tube for protecting an underground power distribution line according to the present invention comprises: a bottom plate (10) consisting of a main body (11) of a quadrangular plate, multiple pile holes (12) vertically penetrating the edge parts of the main body of the plate, top parts (13) protruding downward from the bottom part of the main body of the plate to correspond to the pile holes, behavior guiding protrusions (14) protruding respectively from both right and left sides of the upper surface of the main body of the plate, and multiple behavior guiding rollers (15) installed on the upper surface of the main body of the plate to be able to pivot; multiple piles (20) for fixing the bottom plate underground by having head parts supported on the pile holes of the bottom plate and having the remaining parts settled underground below the bottom plate through the pile holes and the top parts of the bottom plate; a wiring block (30) including one or more wiring grooves and having a bottom part supported on the behavior guiding rollers of the bottom plate; a cover (40) consisting of a main body (41) of the cover having a section in the shape of an arch and protecting the wiring block by covering the wiring block, and behavior guiding grooves (42) formed respectively on the lower end parts of both right and left sides of the main body of the cover, having the behavior guiding protrusions of the bottom plate inserted therein and connected to the behavior guiding protrusions via connection pins (43); and behavior guiding pins (50) combined with the main body of the cover and the wiring block to guide the lateral behavior of the cover. |
