摘要： PURPOSE:To make deformation small in quantity as well as to secure stability without impairing right-weight and easiness in execution by arranging materials which are comparatively high in compression stiffness within the inside of a light weight banking composed of materials small in compression stiffness to make it a composite structure with the materials for light weight banking. CONSTITUTION:The ground surface is excavated to a specified depth, a bottom concrete 17 is set up on the face of excavation 18, and furthermore, foamed styrol blocks 11 are piled up to a specified height. In the second place, wall panels 14 and 14 are set up, a plurality of vertical holes are concurrently provided for foamed styrol blocks 16 with a specified density by means of heating wires and the like. And said holes are filled with materials such as concrete, mortar, plastics and the like which are comparatively high in compression stiffness so that pile bodies 15 and 15 are thereby formed. This therefore permits vertical load applied after a banking has been constructed, to be mostly taken care of by the pile bodies 15 and 15 high in compression stiffness, thereby making it possible to make the quantity of deformation small to a lesser extent.
