GROUND REINFORCEMENT STRUCTURE AND GROUND REINFORCEMENT METHOD
To provide a ground reinforcement structure allowing reinforcement to be carried out using small sized piles allowing a construction to be carried out with a small machine.SOLUTION: A ground reinforcement structure for reinforcing a ground under a building 1 has: a plurality of reinforcement members 2 composed of a reinforcement core material 21 inserted into the ground and having the periphery solidified with a filler and a pressure receiving body 22 connected to an upper part of the reinforcement core material 21; and a stress transfer layer 3 composed of granular backfilling material such as sandy soil, crushed rock, improvement soil, and lightweight banking material right under a bottom surface 11 of the building 1, wherein the pressure receiving body 22 is arranged in the stress transfer layer 3.SELECTED DRAWING: Figure 1
【課題】小型の機械で施工が可能な小径杭により補強を行うことができる、地盤補強構造を提供する【解決手段】構造物１の下部の地盤を補強する地盤補強構造であって、地盤中に貫入し周囲を充填材によって固化した補強芯材２１と、補強芯材２１の上部に連結する受圧体２２と、からなる補強材２を複数有し、構造物１の底面１１の直下に、砂質土、砕石、改良土、軽量盛土材等の粒状の埋め戻し材からなる応力伝達層３を有し、応力伝達層３内に、受圧体２２を配置することを特徴とする、地盤補強構造。【選択図】図１
