Since it is fixed, not only does the concrete wall be firmly installed in the basement, but the construction work to construct the concrete wall in the basement is simple, thereby shortening the construction period and significantly reducing the amount of material used, thereby reducing construction costs.

In addition, the present invention is to install the earth support plate (20) while excavating the ground by putting the thumb piles (10) for mounting and supporting the ground on the ground and installing the earth anchor (40) on the back cut wall (W) of the thumb pile (10) After installing and piercing the earth anchor 40 through the thumb pile 10 for supporting and installing the concrete panel 30, the concrete panel 30 is used as the earth anchor 40 while the concrete panel 30 is contacted and supported by the thumb pile 10 for supporting and installing the support. The inner concrete wall 50 is repeatedly constructed by repeating fixation, and the inner concrete wall 50 is installed with a formwork, and concrete is poured to form the outer concrete wall 70 to construct the concrete wall in the basement. Not only will the concrete wall be firmly constructed, but the construction work of constructing the concrete wall underground will be simplified to shorten the construction period. When the formwork includes a plurality of concrete panels 30, the construction of the outer concrete wall 70 becomes easy and simple.

In addition, the present invention is to separate the earth anchor 40 fixed to the inner concrete wall 50 from the inner concrete wall 50 before constructing the outer concrete wall 70, and then to construct the outer concrete wall 70 Since the prestress between the thumb pile 10 for supporting and installing the support and the inner concrete wall 50 and the cut wall W is removed, the thumb pile 10 for supporting and installing the support can also be extracted and recovered, thereby reducing cost.

In addition, since the connection between the ground anchor 40 and the inner concrete wall 50 is released, the inner concrete wall 50 is not affected by the damage of the ground anchor 40 buried underground during additional excavation work next to the structure. It does not.
