Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall block made of concrete, which is convenient for installing a particularly large retaining wall block, and a pedestal block for installing the retaining wall block and a method of installing the retaining wall block for retaining earth. .

[0002]

2. Description of the Related Art Retaining wall blocks are conventionally constructed by placing concrete on a foundation on which stones or lumps of stone are piled up to form a foundation concrete board, and holding the foundation on the foundation concrete board. The wall block is installed.
At that time, the larger the retaining wall block is, the larger the amount of miraculous stones and stones must be constructed to construct a solid foundation concrete board, which is a drawback of high cost. The present invention has solved such problems by focusing on the use of a pedestal block.

[0003]

The gist of the present invention will be described with reference to the accompanying drawings.

The present invention relates to a pedestal block for installing a retaining wall block, which is characterized in that a concrete front wall 1 formed to be solid is connected to an enclosure wall 2 having a planar U shape lower than the front wall 1.

Further, the present invention relates to a pedestal block for installing a retaining wall block according to claim 1, wherein pillars are erected on upper left and right corners on the rear side of the rectangular enclosure wall 2.

[0006] Further, the concrete front wall 1 formed to be solid
A pedestal block a, in which a planar U-shaped enclosure wall 2 lower than the front wall 1 is continuously installed, is installed on the base body 3, and water permeability of crushed stones and gravel is secured in the enclosure wall 2 of the pedestal block a. Filling possible filling material 4, placing a foundation concrete board 5 on the enclosure wall 2 filled with this filling material 4, and erection a retaining wall block 6 for retaining soil on the foundation concrete board 5. The present invention relates to a method of installing a retaining wall block for retaining soil.

[0007]

The base body 3 is constructed, the pedestal block a is installed on the base body 3, and the filling material 4, for example, crushed stones called crusher run generated when crushed stones are filled in the surrounding wall 2 of the pedestal block a, is filled up. It is packed, the foundation concrete plate 5 is placed thereon, and the retaining wall block 6 is installed on the foundation concrete plate 5.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show two preferred embodiments of the present invention. FIG. 2 shows a first embodiment and FIG. 3 shows a second embodiment.

The first embodiment will be described in detail.

The present invention relates to a pedestal block for installing a retaining wall block in which pillars are erected at the upper left and right corners of the rear side of the rectangular enclosure wall 2.

As the filling material 4, a crusher run which can secure water permeability at a low cost, other lumpy scrap metal which does not prevent water permeability, gravel, other lumpy filling material 4, or a mixture thereof is used as a substitute, It may be mixed with crusher orchid.

The second embodiment will be described in detail.

An auxiliary pedestal block a'inverted in direction is installed on the rear side of the pedestal block a with their backs facing each other.

As in the first embodiment described above, a crusher run is packed in both enclosure walls 2 to form a wide base concrete plate 5.
And a large concrete retaining wall block 6 is installed on it.

[0015]

Since the pedestal block of the present invention is constructed such that the concrete front wall which is formed to be solid is connected to the enclosure wall having a U-shape which is lower than the front wall, the foundation concrete is placed on the enclosure wall filled with crusher run. When the plate is cast, the front wall is higher than the surrounding wall, so concrete can be prevented from flowing out to the outside of the front wall, and it is possible to easily form a thick and robust foundation, and even for large retaining wall blocks. Can be installed safely. At this time, if the front wall that is taller than the surrounding wall is used and the top of the front wall is projected from the foundation concrete plate, the retaining wall block can be prevented from sliding forward due to earth pressure, so it can be installed more firmly. It will be.

A pedestal block in which a solid U-shaped concrete front wall is connected to a flat U-shaped enclosure wall lower than the front wall is installed on the base body, and crushed stones and gravel are placed in the enclosure wall of the pedestal block. A filling material that can secure water permeability such as is packed, a foundation concrete plate is placed on the enclosure wall filled with this filling material, and a retaining wall block for earth retention is erected on this foundation concrete plate Since the method is adopted, it is possible to construct a thick and wide foundation easily and at a low cost by using less concrete, and because the retaining wall block is installed on it, no matter how large and heavy the retaining wall block is. It is an excellent method of installing a pedestal block for retaining wall blocks and a retaining wall block for retaining soil, which can be safely installed and also have the above effects.
