(57) [Abstract] [Problem] Injectable penetrability is excellent and initial strength development is weak, so secondary injection and tertiary injection are possible, not only can voids be completely filled, but long-term strength development is also excellent, so it is strong. To provide an inexpensive injection material that can form a solid ground, has good injection properties, and an injection method using the same. SOLUTION: The injection method is characterized by injecting an injection material containing fly ash, a calcium compound, and an alkali stimulant, and a slurry of the injection material. |
