Zusammenfassung:PROBLEM TO BE SOLVED: To provide a revetment reinforcement method and a grout material used for the same which can evenly reinforce an entire riprap layer of a revetment with the grout material and prevents the injected grout material from being separated and leached out into the sea even when the riprap layer is immersed in seawater.SOLUTION: A grout material, which comprises: per 1 m, a cement-based solidification material of 200 kg to 450 kg; fly-ash of 200 kg to 450 kg; thickener of 23.4 kg to 70 kg; and water of 600 kg to 850 kg, has a flow value of 200 mm to 500 mm. In a revetment reinforcement method, the grout material is injected into a riprap layer having a coefficient of permeability of 1×10cm/sec to 1×10cm/sec.
