A pile connection unit for self-standing retaining construction is disclosed. The pile connection unit for self-standing retaining construction of the present invention is fixedly coupled to each of the pair of piles so as to connect a pair of piles spaced apart from each other to each other using a steel wire to support the steel wire, a bracket body capable of being fixedly coupled to a pile in a state hooked on the top and provided with a through hole so that the steel wire can be inserted therethrough; and a steel wire support portion provided inside the through hole and on the inner wall forming the through hole, and supporting the steel wire to allow the steel wire to move in one direction with respect to the bracket body by an external force but suppress movement in the other direction It is characterized in that it includes. According to the present invention, the piles are installed in two rows to be spaced apart in the vicinity of the excavation surface of the excavation site, and the piles in the two rows are connected to each other using a steel wire, a first connection unit and a second connection unit, so the installation of a strut is required Not only can the construction period be shortened, but the operator can easily install and construct it, and the stability of the retaining wall can be greatly improved.
