PURPOSE: A high-depth prefabricated temporary earth retaining structure is provided to maintain structural stability by preventing horizontal displacement generation of an earth retaining wall body. CONSTITUTION: A first row multistage H type steel material is consecutively welded and connected to first row basic H type steel materials(24) which are vertically or horizontally installed in the ground to a design depth. A multistage steel sheet is vertically inserted in the ground with the design depth by being consecutively connected to a basic steel plate(13) vertically inserted in the ground between the first row multistage H type steel materials. A second row basis H type steel material(25) is vertically installed into the ground. An H type steel-combined reinforcing material(21) is welded between the first row basis H type steel material and the second row basis H type steel material.
