PURPOSE:To simplify the construction of sheathing work as well as reduce the cost of construction by utilizing newly the upper part of sloped ground by forming a sheathing portion with a vertical wall face of gas concrete. CONSTITUTION:A drain layer 11 and a stone masonry layer 13, together with a water-proof film 12 and a drain pipe 14, are orderly stacked up on the outside concrete foundations 10 and 6 of the sloped wall 3 of a tiered site 1. When these layers 11 and 13 reach given heights, gas concrete 17 is two-stepwise placed into the space of an inverted trapezoidal form between the layer 13 and a formwork vertically erected on the ground 2 to fill the apertures and spaces in the broken stones 13a of the layer 13 with foamed concrete in order to form an inverted trapezoidal large sheathing portion 4 whose upside is positioned slightly lower than the site 1. New ground on the upper part of the sloped ground, having a length of W, is further constructed for permitting another utilization according to uses. |
