The present invention relates to an underground anchor and, more specifically, an underground anchor provided to be fundamentally corrosion resistant, thereby improving durability, construction quality, transportation, storage, handling, construction ability and safety, and securing stable bearing power. The underground anchor according to the present invention comprises an anchor body having a linear structure and providing bearing power against an applied external force; multiple anti-corrosion units which are composed of rod shape members made from anti-corrosive materials having hollow parts therein and are inserted to the exterior of the anchor body with a gap therebetween; and a connection unit which is inserted into a position corresponding to the gap to have both ends fixed on the outer surface of the anti-corrosion unit and a center part pressed and fixed onto the outer surface of the anchor body. The underground anchor according to the present invention is provided to use an anti-corrosion unit to protect an anchor body in a watertight manner; to have the anti-corrosion unit securely fixed on the anchor body by using a connection unit in order to fundamentally prevent corrosion of the underground anchor, thereby significantly improving the durability and construction quality of a structure constructed by using a soil nailing construction method; to have the anti-corrosion unit coupled to the exterior of the anchor body, thereby improving transportation, storage, handling, construction ability and safety; and to make the connection unit, which has an outer diameter larger than that of the anchor body, securely fixed on a grouting unit, thereby significantly enhancing bearing power of the underground anchor. |
