To provide a ground reinforcing structure capable of reducing horizontal pressures to the wall surfaces of various wall sections by the elastic characteristics of fractured tire rubber chips (tire shreds) cutting and fracturing a waste tire in slices.
In the ground reinforcing structure, a backfilling material 1 is formed to the wall surface of a wall section A by using a fractured rubber chip layer 2, and the periphery of the backfilling material 1 is compacted by the backfilling material 4. It is preferable that the backfilling material 1 is formed by laminating a covering layer 3 on the fractured rubber chip layer 2. It is preferable that the fractured rubber chip layer 2 and a soil layer 3 are laminated alternately. A surface brought into contact with the backfilling material 4 in the backfilling material 1 can be formed in a slant shape.
