Claims (5)
- 地盤面上に支圧版を敷設する工程、地盤中に外周部に複数の貫通孔を有する孔開き鋼管からなるアンカー体を施工する工程、当該アンカー体の基端側を支圧版に定着する工程、地盤中に可塑状ゲル注入材を、周辺土を周囲に押しやるように徐々に拡大して周辺地盤を締め固めるように圧入することにより、アンカー体と一体の定着体を形成する工程とからなる地盤安定化工法において、アンカー体の基端側を支圧版に定着した後に、地盤中に可塑状ゲル注入材を圧入することによりアンカー体と一体の定着体を形成することを特徴とする地盤安定化工法。
- 定着体はアンカー体の長手方向に複数形成し、そのうち、地表面より深い方の定着体を先に形成し、その後地表面に近い方の定着体を形成することを特徴とする請求項1記載の地盤安定化工法。
- 定着体は、アンカー体の長手方向に間隔をおいて複数形成し、その後、前記定着体と定着体との間に新たに定着体を形成することを特徴とする請求項1記載の地盤安定化工法。
- 定着体は、アンカー体の長手方向に複数同時に形成することを特徴とする請求項1記載の地盤安定化工法。
- 定着体は、地盤中の脱水を併用しながら施工することを特徴とする請求項1〜4のいずれかひとつに記載の地盤安定化工法。」
