PURPOSE:To prevent a liquidization phenomenon and improve the qualities of anti-earthquake and constructability and realize cost reduction by putting a formation obtained by mixing at a specific weight ratio cement, sand, bentonite and water into the organic soft ground such as peat, humus, viscous soil of a humus nature, clay mixed with organism. CONSTITUTION:A strengthening formation is obtained by mixing cement: sand: bentonite: water at the weight ratio of 1.0:2.0-8.0:0.2-1.5:0.5-3.0. When this strengthening formation is put into a predetermined place at the organic soft ground such as peat, humus, humus nature viscous soil, organism mixed clay having a thickness of H', the injected liquid flows in an arrow direction. Each time, as pressure tightness, dehydration and drainage are repeated, the intensity of the ground necessary for a ground improvement object range H is obtained. |
