Provided is a structure for a temporary facility installed to bear external pressure due to soil pressure by reinforcing the wall of an underground excavation hole, thereby efficiently preventing the deformation of the temporary facility due to the soil pressure by reinforcing the stiffness of a retaining member in the temporary facility to construct an underground structure; thereby reducing the construction costs of the temporary facility, and safely constructing the temporary facility by easy structural calculation for the construction of the temporary facility. The structure for the temporary facility comprises: the retaining member touching the wall of the excavation hole in order to support the excavation hole, and vertically installed in the ground; a first wire member of which one side is installed to be fixed to the lower side of the retaining member, and the other side formed to be extended longitudinally towards the ground; a reaction force supporting unit installed to be fixed on the retaining member, and supporting the first wire member; and a first tightening unit having a wale, installed to be fixed to the upper side of the retaining member, and reinforcing the stiffness of the retaining member in order to prevent deformation of the retaining wall due to the soil pressure by tensely fixing the first wire member vertically extended through the reaction force supporting unit, wherein the reaction force supporting unit generates a reaction force against a stress, which is applied to the retaining member, by supporting the first wire member while the first wire member is separated from the retaining member at a certain interval. |
