A block construction for high voltage cable protection for underground is provided to prevent the damage of the high voltage cable by preventing the deformation of the outer shape in spite of the ground subsidence or the sand loss. The basic supporting plate(30) is installed at the floor of underground. The top and bottom main bodies (10,20) are installed on the top of the basic supporting plate. The top and bottom main body gear into the gear form. The bottom main body comprises a bottom plate, a connection unit, the trapezoid plate and a connection bolt. The connection unit is formed in the corner of the bottom plate of rectangular. The trapezoid plate is perpendicularly extended from X direction of both side of the bottom plate. The trapezoid plate forms the extra space in Y direction of both side of the bottom plate. The connection bolt is perpendicularly protruded in the top both side of the trapezoid plate. The top main body comprises a top plate, a connection unit, the reverse trapezoid plate and a flange. The connection unit is formed in the corner of the top plate of rectangular. The reverse trapezoid plate is perpendicularly extended from X direction of both side of the top plate. The reverse trapezoid plate forms the extra space in Y direction of both side of the top plate. The flange is horizontally extended from the bottom of the reverse trapezoid plate. |
