Abstract

PURPOSE:To prevent uneven settlement, lean, etc., due to soft ground and obtain a sufficient bearing force as a foundation for a relatively large building, by supporting a slab by the whole top face of binding fillers and continuous footings. CONSTITUTION:Rubble stones 3 are laid in a cut ditch 2 in the ground 1 and compacted and a leveling concrete 4 is placed to form a foundation base 5. And continuous footing 6 forms are assembled along the foundation base 5 to nearly correspond to the arrangement place of the external walls and partition walls of an upper structure to be constructed. Next, binding fillers 12 are charged in the space 11 formed between continuous footings 6 and a slab 18 is laid on the top thereof to support it by the fillers and footings and obtain a foundation structure. The load of the upper structure constructed on the slab 18 is dispersed almost evenly to the fillers 12 and the continuous footings 6 through the slab 18 and transmitted to the ground 1.
