HARBOR CONSTRUCTION CONCRETE BLOCK HAVING A SALVAGE GROOVE

PURPOSE: A harbor construction concrete block having a salvage groove is provided to simplify a manufacturing process of a revetment block, to reduce the costs required to construct a quay wall, and to construct a quay wall more conveniently and promptly. CONSTITUTION: A revetment block (20) and a hollow block (30) comprise grooves (40, 40') hollowed widthwise and formed symmetrically on the both sides of blocks (20, 30), wherein a groove (40) forms a rectangular plane facing vertically downward by the shape of the side cut end of a reverse right triangle and a rebate (45) where a lifting instrument, such as a fork (50) is placed, and the shape of a groove (40') of a hollow block (30) is identical to the shape of a groove (40) of a revetment block (20) having a rebate (45') where a lifting instrument is placed.
