A preloading system of a retaining wall is provided to form a working space in a construction site by transferring the optimum preload to a retaining wall easily, and regulating the preloading area and the arrangement of struts. A preloading system of a retaining wall comprises struts(1) installed in an inside space of a pit excavation site at regular intervals and attached with a hydraulic jack(2) to generate pressure force, an axial force transfer body(3) connected to an output end of the hydraulic jack and composed of a straight pile(4a) and inclined piles(4b) contacted with a loading plate by a rubber plate(5) to transfer the pressure force of the hydraulic jack widely to a loading plate as preload, a loading plate(6) formed by arranging a plurality of wales(7) to be piled up mutually, reinforced with a stiffening plate(8) to have high shear stress and attached to a wall pile buried under the ground at right angles to apply preload on the wall pile, and a steel plate(10) equipped with a stopper(9) or a stopper attached to the contact surface of the loading plate and the axial force transfer body to retain the straight pile and the inclined piles within the limited location without sliding to transfer preload from the axial force transfer body to the loading plate without loss. |
