  • Publication number: 20180112368
    Abstract: A method for improving ground is capable of preventing a clod whose representative size is large from remaining in the ground. The method for improving ground includes cutting a ground by injecting a cutting fluid (e.g. high-pressure water or high-pressure air: including a case where a solidification material is injected) from jet devices, feeding a solidification material, mixing the cut ground, the cutting fluid and the solidification material, and agitating a mixture thereof to form an underground consolidated body. A plurality of nozzles are located at an interval in a vertical direction in the jet devices, and when the cutting fluid is injected, a cutting fluid is injected from an upward nozzle in a downward skewed direction, and a cutting fluid is injected from a downward nozzle in an upward skewed direction.

  • Publication number: 20170204580
    Abstract: A method for improving ground is capable of improving the strength or quality of an underground consolidated body formed by reducing the ratio of water to a “rich-mixed” solidification material (a cement) (W/C), assuredly carrying the solidification material from a feed source to a jet device, and reducing the amount of solidification material treated as an industrial waste in a construction process. The method for improving ground includes a step of drilling a drilling hole in the ground to be improved, a step of moving (pulling up) a jet device in a vertical direction by rotating the same while the jet device is inserted into the drilling hole and a fluid for cutting the ground (a stable liquid or a partition forming material) is injected from the jet device, and a step of injecting a solidification material from the jet device.
