To prevent the occurrence of cracks caused by the contraction of the lower part of a solidified wall by using an etholin guide producing solidifying material as a solidifying material when a solidifying material is mixed in stabilizing liquid used for excavation or muddy water and solidified.
For building a muddy water solidified wall by mixing a solidifying material in stabilizing liquid used for excavation or muddy water and solidifying this, an etholin guide producing solidifying material is used as a solidifying material. This solidifying material produces a great deal of etholin guide when it is hydrated. Also, since this solidifying material produces, when mixed with stabilizing liquid or muddy water, etholin guide and is solidified, a produced hardened body, in other words a hardened wall, is provided with expanding ability and a good strength. Further, for this solidifying material, for example one containing auin and/or blast furnace slag of 2.4 to 60wt.%, anhydrous gypsum of 12 to 33wt.% and usual cement of 17 to 85.6wt.% is used. Thus, contraction in the lower part of the solidified wall is suppressed during solidifying and the occurrence of cracks is prevented.
