上面の傾斜法面13に、構造体支持材15が配置される。4 to 12 show a structure supporting method disclosed in this specification. In this method, first, as shown in FIG. 4, a ground 11 on which an anchor (not shown) is installed is mounted. The structure support member 15 is disposed on the inclined slope 13 on the upper surface.
この構造体支持材15は、第５図に示すように、一般に
十字状に形成されており、その形状は、後に構造体支持

27に一定張力が付与される。At the same time as the placement of the structure 17 on the structure support member 15, the structure support member 15 is compressed by the weight of the structure member 17, as shown in FIGS.
A constant pressure is applied to the cement milk 23 of 21 and the cement milk 23 is applied to the structural support material 15 near the cement milk reservoir 21.
Are penetrated into a substantially cylindrical shape, and as shown in FIG.
In a state where 17 is in close contact with the inclined slope 13 via the structure supporting material 15, the permeation range 25 in which the cement milk 23 has permeated is consolidated, and as shown in FIG.
27 is given a constant tension.
