On the other hand, the upper edge of the rear lid panel of the second stage is supported by the lower half of the supporting piece 6 of the second stage separator 4 to which the base is attached to the leg rest 3 of the second stage block body. When the block main body and the back lid panel are set in this way, the backing material is packed into the back side of the panel in the same procedure as described above, and the back is filled up to the second-stage separator set surface. Concrete is cast and a second retaining wall block is constructed. Then, as shown in FIG. 7, the block bodies of the third and fourth stages and the butt lid panel are sequentially stacked on top of this, and the backing material is packed and the stuffed concrete is poured according to the above procedure. And
When the retaining wall block is piled up and constructed and a predetermined number of steps are constructed, a top concrete block is placed thereon in the same manner as before, and a backing material is packed between the concrete block and the excavation slope A to construct a predetermined retaining wall block. To end. Note that the third stage and the fourth
The lower-stage rear lid panel is set close to the block body based on a previously calculated earth pressure, and the lower edge of the third rear lid panel is the above-mentioned stopper 8 (see FIG. 6). ) Is fixed to the third-stage concrete casting surface 12.

In the above-described embodiment, the retaining wall blocks 1 are stacked in four steps on the root stone block 9, and the height of the fourth retaining wall block is lower than the other blocks. The number of steps for stacking the blocks may be four or less, or five or more, depending on the height of the wall slope. Further, in this embodiment, three leg rests 3 are provided, but two leg rests may be provided according to the width of the block main body. Further, a single lid lid panel is used. The two panels may be used, and in this case, the butted portions of the two panels may be supported by separators set on both sides of the footrest at the center of the back of the block body. In addition, the pattern of the turbulent stone piled wind formed on the surface of the block main body can be variously selected according to the scenery of the construction place and the like.

[0009]

As will be understood from the description of the above embodiment, the present invention has at least two or more leg rests on the back surface and has a disturbed surface and is formed in a masonry style. A retaining wall block is configured from the installed butt lid panel and the separator, and when the block main body is stacked up and down, the upper and lower leg retainers overlap with each other, and the block main body and the butt lid panel are combined. The separator can bite into the concrete when it is integrally supported and the stuffed concrete is poured between them, and can firmly connect the block body and the tail lid panel. Therefore, the weight can be significantly reduced to about 1/5 of that of a conventional L-shaped or rectangular solid free-standing block which is about 5 tons in 1 m width. Therefore, it is possible to carry a small truck without using a large truck or a crane as in the related art, and also to stack a block body or the like with a small construction machine. Therefore, the transportation cost to mountainous areas, landslides, rivers and development sites where the access road to the construction site is inadequate is low, and the work is easy because of the light weight, and the block surface is disturbed and formed in a masonry pattern. The entire retaining wall block constructed from the building is rich in elegant aesthetic beauty, and when the above retaining wall block is constructed on the river bank or road slope, it is possible to climb and descend using the unevenness of the masonry style pattern Practical effects such as can be exhibited.

In the present invention, a retaining wall block is constructed simply by assembling the above-described block main body, the stuffing lid panel, and the separator without using a scaffold or the like separately at a construction site and without using large-sized equipment. In addition, they are integrally and firmly connected, and after the concrete is poured into the body, the leg stays and the separator are embedded in the concrete to more securely connect the retaining wall block. Further, since the rear lid panel is provided on the back of the leg rest so as to be adjustable in position and the panel and the block body are supported by the separator, a gap formed by the block body and the panel is provided. Can be freely adjusted to a pre-calculated interval. Therefore, it is possible to keep the amount of concrete used in the body to an appropriate amount, and to reduce costs. Further, according to the present invention, it is only necessary to stack the block main body and the embedding panel, so that the upper and lower edges of the block main body and the retaining frame member are integrally tightened or the die frame plate is embossed with concrete, as in the prior art. Since it is not necessary to perform an operation such as pulling up each time the device is installed, the work of constructing the retaining wall block can be easily and quickly performed, and excellent effects can be achieved such as reduction of man-hours and labor saving. Also,
The retaining wall blocks that are stacked in the required number of steps are arranged in a row and the retaining wall blocks of different widths are not placed in the same width, but are alternately arranged vertically and arranged in a mosaic pattern to make the retaining wall slope more aesthetic It is possible to provide a retaining wall slope that can be constructed in a sense and that can climb up and down using the unevenness of the masonry-like pattern.
