Abstract

The present invention relates to a retaining wall structure, comprising: an inclined retaining wall member (100) which is inclined whose bottom is more into an excavation area (A) than its top; a bracket (200) which is combined with the inside of the inclined retaining wall member (100); a walling (300) which is combined with the top surface of the bracket (200); and weights (400) which are piled up on the walling (300) along an inclined surface of the inclined retaining wall member (100). According to the present invention, the inclined retaining wall member (100) is installed to be inclined toward the inside of the excavation area. Since the weights are combined with the top of the walling (300), the weight of the weights works on the external side of the excavation area. The weight of the weights prevents the inclined retaining wall member (100) from falling into the excavation area by soil pressure. As such, it is not needed to install a supporter or a raker and is able to secure a work space in the excavation area.
