固化材の噴射確認方法及び高圧噴射攪拌工法

Japanese Patent JP7458968

B2

To provide an injection confirmation method of a solidification material and a high pressure injection agitation method capable of securely confirming a status of injection of a solidification material in real time.SOLUTION: An injection confirmation method of a solidification material C and a high pressure injection agitation method include: a step of making an injection pipe 21 inserted into a ground G ascend while rotating around an axis and injecting the solidification material C from an injection nozzle 21A to construct a solidification body R; a step of inserting an inspection pipe 51 into the ground G; and a step of inserting a measurement apparatus 52 comprising a capturing device 53 and a vibration meter 54 into the inspection pipe 51. And, in a state where a transparent pipe 51B is used in a part of the inspection pipe 51 which the solidification material C is planned to reach, a capturing direction of the capturing device 53 is made to be a downward direction, and the capturing device 53 is positioned above a depth D1 which the solidification material C is planned to reach, the measurement apparatus 52 is made to ascend so as to cooperate with an ascent of the injection pipe 21. In the ascent process, the ground G around the inspection pipe 51 is captured by the capturing device 53.SELECTED DRAWING: Figure 1
