However, when the length of the retaining wall to be constructed is different from the drainage of the standardized Euroform panel 20, that is, the length of the plurality of Euroform panels 20 connected and fastened, the gap between the Euroform panels 20 or the Euroform panel is different. By inserting a wheel spacer (Filler Spacer) to fill the gap between the 20 and the corner post 10, and fixed by the fastening means 30, the length difference between the retaining wall and the flow-form panel 20 is filled.

As described above, the Filler Spacer is formed between the Euroform panel 20 and the Euroform panel 20 and the corner posts, which are panels that form the formwork that is installed to support the concrete when the concrete is placed for the installation of the retaining wall. 10) If there is a gap between the installation of the flow-formed panel 20 to be the same length as the length of the retaining wall is installed, the most efficient formwork installation, but the length of the retaining wall If the length of the yurom foam panel 20 is different from each other, the filler spacer is inserted into the gap caused by the difference of the length, and is fixed between the panels by the fastening means 30 to fill the gap. The poured concrete will not leak.

As shown in FIG. 1, at least one through hole 55 is formed vertically on one surface of the wheel spacer 50 to maintain a predetermined interval, and the through hole 55 includes a flow path panel 20 and a corner post which will be described later. It is formed to correspond to the fastening hole 25 of the (10), the spacing between the through hole 55 is approximately the distance between the fastening hole 25 formed on the side of the flow path panel 20 and the corner post (10). It is formed with a spacing of 1/2 or less.

As described above, the spacing between the through holes 55 is formed to be about 1/2 or less of the spacing between the fastening holes 25, and the height of the wheel spacers 50 and the height of the flow path panel 20 or the corner post 10 are as follows. In the case where a difference occurs, when the wheel spacers 50 are vertically added or cut, the fastening holes 25 and the through holes 55 corresponding thereto are displaced, thereby preventing difficulty in fastening. .

That is, when the spacing between the through holes 55 becomes more fine, despite the addition or cutting of the wheel spacers 50 due to the height difference between the flow path panel 20 or the corner post 10, the fastening holes 25 Through holes 55 corresponding to the presence of the fasteners 30 to be described later to facilitate the insertion, the gap between the flow path panel 20 and the gap between the flow path panel 20 and the corner post 10 is called. The spacer 50 is easily filled.
