| 摘要 |
The purpose of the present invention is to provide a ground improvement method with which it is possible to improve the strength or quality of an underground consolidated body created by lowering a ratio (W/C) of water to a solidification material (cement) (i.e., forming a "rich mix"), and to reliably convey the same from a supply source to an injection device, as well as to reduce the amount of the solidification material that is disposed of as waste when work is carried out. To achieve this purpose, the present invention comprises steps for: digging a borehole (H) in a ground (G) to be improved; inserting an injection device (1) into the borehole (H), and rotating the injection device (1) and moving the same in the vertical direction (pulling up) while injecting a fluid (stabilizer, partition-forming material) for cutting the ground (G) from the injection device (1); and injecting the solidification material from the injection device (1). |
