On the other hand, when two or more retaining wall blocks are connected horizontally with respect to the installation surface, the semi-circular grooves 14 and 24 formed on one side of one retaining wall block and the other The semicircular grooves 14 and 24 formed on the other side of the retaining wall block come into contact with each other to form a cylindrical groove.

On the other hand, such a cylindrical groove can be understood as an insertion area of a reinforcing material that is preferably installed vertically with respect to the installation surface.

Referring to FIG. 8 as an embodiment, in FIG. 8, in a state in which a retaining wall is formed using a plurality of retaining wall blocks 10a and 10b, a groove ( 14a, 14b) forms a cylindrical groove, and an example in which a reinforcing member such as a reinforcing bar is inserted into the cylindrical groove can be seen.

At this time, the above-described reinforcing member is prepared with a length longer than the total height of the retaining wall formed by the retaining wall blocks, is inserted into the cylindrical groove, and then has a form in which one region of the insertion end is buried in the installation surface, thereby maximizing the reinforcing force. There will be, and the present invention is not limited thereto.

On the other hand, a retaining wall block including at least one of the aforementioned retaining wall block 10 for a straight section and the retaining wall block 20 for a curved section may exhibit different functionality depending on the material injected into the cavity.

As an example, when cement paste containing aggregate is injected as the material injected into the cavity described above, since the cement paste will be hardened into concrete by a hydration reaction, the retaining wall block is used as a permanent retaining wall permanently installed at the construction site. can make it functional.

In addition, as another embodiment, when a material including at least one of soil under water is injected into the above-described cavity, in a state in which at least one of water and soil is injected into the cavity, function as a retaining wall And, when the water and soil injected into the cavity are removed, it can be demolished to function as a recycling retaining wall that can be reused one or more times at one or more construction sites.

At this time, in a more preferred embodiment of the present invention, in order to prevent the aforementioned water and soil from overflowing and being lost, when a material containing at least one of water and soil is injected, the inlet 11 formed in the retaining wall block , 21) as a sealing means (not shown) for sealing or opening, a door or a cover member may be further included, and the present invention is not limited thereto.

In addition to the above-described embodiment, in another embodiment of the present invention, as a material injected into the above-described cavity, a synthetic resin material including at least one of polyurethane, polystyrene, and polyethylene is processed in a molten state and injected. In this case, the synthetic resin material in a molten state in the cavity may be cured by a separate curing treatment means to function as an insulating retaining wall.

It will be understood that by filling the internal cavity of the retaining wall block with the synthetic resin material, it is possible to provide a functional retaining wall that exhibits an insulation effect by preventing heat transfer by convection, conduction, and radiation.

That is, in summary, the retaining wall block referred to in the present invention functions as a permanent retaining wall when cement paste is injected, depending on the material filled in the internal cavity of the retaining wall block structure, and when soil and water are injected, the injected soil and water It functions as a recyclable retaining wall that can be recycled to other construction sites by discharging the It has the effect of providing a structure.
