PROBLEM TO BE SOLVED: To provide a natural-ground reinforced earth method, in which the integrality of a ground and the natural-ground reinforced earth member is improved by preventing a dispersion into the ground of self-hardening fillers and the development of the crack of the fillers, the solidification strength of the fillers is enhanced by promoting the discharge of excess water or the like and the ground such as a face of a slope is stabilized, and a natural-ground reinforced earth member used for the method. SOLUTION: In the natural-ground reinforced earth method in which a baggy body 3 in which a front end section having approximately the same length as the excavation length L of the excavated pit 2 is closed is inserted into the pit 2 formed by drilling the ground 1 and self-hardening fillers 5 are injected into the baggy body 3, the diameter of the baggy body 3, in which the fillers 5 are injected, is expanded at a value larger than the diameter D of at least the pit 3 extensively over an overall length by pressing and injecting the fillers 5 while a drainage material 4 is disposed extensively over the overall length on the surface of the baggy body 3. In the method, the baggy body is installed so that the end section of the material 4 is led out outside the pit 2. COPYRIGHT: (C)2004,JPO&NCIPI
