[PROBLEMS] To provide liquid flowability in a long hose, and after pressure in the ground, it does not penetrate between soil particles and gels in a lump without deviating outside a predetermined range, and the density of surrounding earth and sand is increased. A ground injection material for ground reinforcement, a ground reinforcement method using the same, a ground injection management method, and an injection management device are provided. A ground injecting material to be injected into the ground through an injection hole drilled in the ground, wherein fly ash, a calcium-based powder hardening material and water are active ingredients. This is pressed into the ground, and the soil particles are pushed to the periphery by expanding the ground injection material gel to strengthen the ground. [Selection figure] None |
