A block structure for protecting an underground high voltage cable of a building is provided to prevent subsidence of the cable or burying according to soil loss, by surrounding the underground high voltage cable with the block structure. According to a block structure for protecting an underground high voltage cable buried underground of a road, a basic block(10) is integrated with a bottom box(12) having an insertion part(17) divided by a partition(15) formed with a through-hole(16). The partition is formed below a top plate(11) having a stake insertion hole(13) and a number of connection holes(14). A sealing rubber(20) adheres to the partition by being inserted into the insertion part of the basic block, and has a number of through-holes(21) in the center. An extended block(30) adheres to the sealing rubber by being inserted into the insertion hole of the basic block, and has a number of through-holes(31), and has a number of screw holes(32). A number of hollow pipes(40) are inserted into the through-hole of the extended block. A connection bolt(52) connects a fixing stake(51) for fixing the basic block to the ground, the basic block and the extension block. |
