PURPOSE : An earth-retaining panel is provided to improve horizontal resistance against lateral pressure of an earth-retaining wall body, to intercept underground water and surface water, and to improve safety and economical efficiency in construction. CONSTITUTION : An earth-retaining panel(10) comprises a main panel(11), a sliding panel inserted in the main panel, an auxiliary panel installed in the main panel correspondently to the sliding panel, a combining member(14), and a wedge pin(15). An insertion groove(111) is formed to the upper part of the main panel and an insertion protrusion(112) is formed to the lower part of the main panel. A longitudinal through hole(114) is formed in the front of the main panel, plural insertion holes(115) are formed in the lower end of the through hole in the longitudinal direction, and guides(116) are installed to sides of the insertion hole. In the sliding panel, a slide hole is formed in the front correspondently to the through hole of the main panel and an inner hole through which a cable(20) passes is formed in one side. A support with a rotating roll is attached to the inner wall surface of the sliding panel to settle the cable. In the auxiliary panel, a settling ring where the cable is fixed is attached to the inner wall of one side and a side hole through which the cable passes is formed in the other side. A bellows with an elastic spring is installed between the sliding panel and the auxiliary panel. The combining member is connected to the other side of the cable connected to the settling ring and plural fitting holes are formed in the longitudinal direction in the combining member. The wedge pin is fitted into the fitting hole and the insertion hole. © KIPO 2006
