The present invention relates to a prefabricated retaining wall installed without a form. The prefabricated retaining wall comprises: multiple front precast concrete (PC) panels having multiple holding rings inserted in the rear surface, obliquely inclined backward from the front side of the ground or a foundation concrete structure at a predetermined angle, and continuously laminated in a lateral and a vertical direction in multistage; multiple rear PC panels having holding rings inserted in the inner surface and continuously laminated on the ground or the top surface of the foundation concrete structure in the lateral and the vertical direction while being separated from the front PC panels at a predetermined distance; multiple panel gap adjustment and fixation units to increase combination force with concrete placed in a space between the front and rear PC panels while combining the front and rear PC panels to maintain the predetermined distance; multiple H-beams installed in a state where the rear surface is vertically erected to be in contact with the inner surface of the rear PC panels to prevent the rear PC panels from being moved back; and the concrete placed in the space between the front and rear PC panels to be integrated. Thus, the present invention makes the retaining wall strong and beautiful and allows the retaining wall to have accurate rear verticality and front gradient without forms to form the concrete placing space. Also, the present invention reduces a construction period to drastically reduce manpower and personnel expenses. |
