Title:
GROUT MATERIAL INJECTION METHOD AND INJECTION ASSIST DEVICE
Document Type and Number:
Japanese Patent JP2022080646
Kind Code:
A
Abstract:
To provide a grout material injection method allowing grout material to be adequately injected in a foundation ground.SOLUTION: An injection method of grout material 2 comprises: a crack information acquisition process of acquiring information on cracks 3 in an inner wall of primary boring holes 10; an evaluation process of evaluating continuity of the cracks 3 between the primary boring holes 10 based on the information on the cracks 3 acquired in the crack information acquisition process; a permeability information acquisition process of acquiring information on permeability of the primary boring holes 10; a determination process of determining whether or not injection of the grout material 2 between the primary boring holes 10 is necessary based on the information on the continuity of the cracks 3 evaluated in the evaluation process and the permeability acquired in the permeability information acquisition process; and an injection process of forming secondary boring holes 20 between the primary boring holes 10 and injecting the grout material 2 in the secondary boring holes 20 when the injection of the ground material 2 is determined to be necessary in the determination process.SELECTED DRAWING: Figure 2
