CONSTITUTION: The steel reinforcement spacer for the construction of an underground anchor comprises a body(11); a center hole(10) penetrating the center of the body into which an injection hose is inserted; a plurality of wings(12) protruded outward on the circumference of the body; a mounting plane formed as a streamline groove between the wings to make a steel reinforcement contact; and an elastic groove(14) formed at the center of the wing to reinforce a strength of the wing.
