PURPOSE:To construct retaining walls easy in assembly work and large in strength by a method wherein many hollow slabs onto the outer surface and the inner surface of which irregularity for fitting are provided are stacked horizontally so that one side thereof can serve as a retaining wall surface. CONSTITUTION:Hollow slabs 2A provided with stripe-shaped irregularity 1 consist of asbestos reinforced cement, and the outer surface and the inner surface of the irregularity 1 are synchronized so as to make it possible to fit on each other. In order to build up retaining walls, first, a foundation concrete 4 is placed on the ground at the position of building up and, after aging thereof, the holding slabs A are stacked horizontally thereonto so that the side 3 of the hollow slab 2A may form the outer side. After then, fill-up is performed on the back side, followed by rolling of filled-up soil to complete work.
