SUMMARY OF THE INVENTION In the conventional method of constructing a building basement wall as a composite wall by using the steel aggregate in the earth retaining wall, when the steel aggregate acts as one member of the earth retaining wall. The stress of changes naturally when acting as a member of a synthetic wall, but since the steel aggregate is entirely integrated with the reinforced concrete wall, it is not possible to calculate how the stress changes. Very difficult theoretically and technically. For this reason, it becomes very difficult to design the composite wall, and eventually the retaining wall and the reinforced concrete wall.

In the present invention, since the earth retaining wall constructed on the outside and the reinforced concrete wall constructed on the inside are integrated only in the floor portion to form a coupled wall, lateral pressure such as earth pressure or water pressure is applied. The reinforced concrete wall should resist the horizontal force such as water pressure and earthquake or wind force that has penetrated from the cliff wall. Therefore, the sharing of stress is simplified and the design becomes easier. Furthermore, since the reinforced concrete wall is integrated with the steel aggregate of the mountain retaining wall only at the floor part, it does not generate tensile force on the shear connector installed in that part, and eliminate the cause of rust generation of the shear connector. You can Further, compared with the case of constructing a reinforced concrete wall as an underground wall independent of a mountain stop wall, the stress shared by the reinforced concrete wall becomes smaller, the thickness of the reinforced concrete wall can be made smaller, and the amount of reinforcing bars can be reduced. Especially, in some cases, reinforcing bars may be omitted in the wall portion.
