Therefore, the present invention has the effect that the coupling force of the plurality of continuous walls (A, B) by the uneven coupling by the uneven forming member 300 increases the overall continuous behavior of the plurality of continuous walls (A, B). You can get it.

In addition, the present invention can obtain an excellent ordering effect by increasing the bonding force of the plurality of continuous walls (A, B) by the uneven coupling by the uneven forming member 300.

In addition, in the present invention, when the concave-convex forming member 300, which is a rigid body, is embedded between the plurality of continuous walls A and B, structural stability is further increased by reinforcing adjacent boundary portions of the plurality of continuous walls A and B. Can be achieved.

Hereinafter, for convenience of description, the continuous wall that is pre-constructed among two adjacent walls that are adjacent to each other will be referred to as a 'primary continuous wall A', and the subsequent continuous wall that will be constructed will be referred to as a 'secondary continuous wall B'.

The concave-convex forming member 300 may be formed to correspond to the end surfaces of the primary and secondary continuous walls A and B so as to be in close contact with the primary and secondary continuous walls A and B, respectively.

Concave-convex portions 310 and 320 of the concave-convex forming member 300 may be formed on only one of the surfaces adjacent to the primary and secondary continuous walls A and B, or both surfaces. Hereinafter, for convenience of description, the uneven parts 310 formed on the surface of the uneven parts 310 and 320 of the uneven parts 310 and 320 adjacent to the secondary continuous wall B which are constructed later are first uneven parts 310. ), And the rest of the second uneven portion 320 is called.

Concave-convex portions 310 and 320 of the concave-convex forming member 300 may be formed in various shapes.

For example, the first concave-convex portion 310 of the concave-convex forming member 300 is perforated in the ground adjacent to the concave-convex forming member 300 for the construction of the second contiguous wall (B) after the construction of the first contiguous wall (A). The first groove 312 may be formed in a plurality of first grooves 312 rather than protrusions so that they do not interfere when they are made. The plurality of first grooves 312 may be formed as a point as shown, and although not shown, may be formed in various ways such as linear and mesh shapes.

Furthermore, since the second uneven portion 320 is formed on the surface adjacent to the primary continuous wall A, the unevenness forming member 300 may be more firmly installed on the primary continuous wall A. As shown in FIG. 2, the second uneven portion 320 may be formed of one protrusion 322, but is not limited thereto, and may be formed of a plurality of protrusions 322 or a plurality of grooves.

The water-expandable index member 330 may be applied to a portion corresponding to the circumferential surface of the groove and a bottom surface opposite to the opening of the groove, respectively.

Accordingly, even if water flows between the first continuous wall A and the uneven member 300, or between the second continuous wall B and the uneven member 300, the water-expanding index member 330 expands due to the water. By filling the gap between the primary continuous wall (A) and the concave-convex forming member 300, the gap between the secondary continuous wall (B) and the concave-convex forming member 300, a more perfect order effect can be expected. In particular, even if the water-expandable index member 330 is applied only to a portion of the unevenness forming member 300 can effectively achieve the degree of order.

The concave-convex forming member 300 may be formed in various shapes such as a dot shape, a line shape, and the like. In particular, in the case of the removal type, the concave-convex forming member 300 may be formed in a vertical line shape along the perforation to facilitate removal.
