Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earth retaining block capable of forming a retaining wall on a slope with good workability and improving its appearance.

[0002]

2. Description of the Related Art An inclined surface having a height difference of 1 m or more and exposed soil, that is, a slope is required to form a retaining wall along the slope to stop the soil. Such a retaining wall is usually formed by pouring concrete directly on the slope in the field.

[0003]

However, the one in which concrete is placed on the slope, which is an inclined surface, has a rather monotonous appearance, which impairs the appearance and also requires the trouble of placing concrete on the inclined surface. It is inferior in workability because it requires the required work.

Moreover, it is difficult to make the thickness of the concrete uniform, and the strength of the retaining wall may decrease in some places.

The present invention is based on the provision of a ceramic base body in the shape of an open container, which allows the retaining wall on the slope to be formed with good appearance and good workability, and has weaknesses in strength. The purpose is to provide earth retaining blocks that can be eliminated and improve the construction quality of retaining walls.

[0006]

DISCLOSURE OF THE INVENTION The present invention is an earth retaining block which forms a retaining wall of the slope by stacking along the slope where the soil is exposed, the front wall being the front edge of the bottom plate portion. Portion, a side wall portion on both side edges, and a rear wall portion of a rear edge of the container, and the rear wall portion is inclined with the upper edge toward the rear at substantially the same inclination as the slope. In the rear wall portion of the base body, a locking portion for supporting one end of the pile body supported on the slope is provided, and a back plate receiving groove that opens and extends vertically is formed at a rear position of the side wall portion. There is.

It is desirable that the bottom plate portion has a drain hole. Further, it is desirable that the bottom plate portion is provided with a positioning portion on the lower surface for positioning the upper edge of the side wall portion of the lower earth retaining block when extending forward and backward.

[0008]

The earth retaining block comprises a container-like base body having an upper opening. Therefore, in addition to the improvement of the landscape by the earth retaining block itself, for example, the retaining wall can be greened by planting a plant in the substrate, which can enhance the appearance and beautify the environment.

Further, since the rear wall portion of the base body is inclined at substantially the same inclination as the slope, and the rear wall portion is provided with the locking portion for supporting one end of the pile body supported on the slope surface, It becomes possible to firmly support the earth stop block on the slope, and a uniform retaining wall having no weakness in strength can be formed with good workability by stacking the earth stop blocks, and the construction quality can be improved.

Further, since the back plate receiving groove is formed at the rear position of the side wall portion of the base body, the soil exposed on the slope is cut off above the base body by using the back plate supported by the back plate receiving groove. It is possible to form a green retaining wall with good workability.

Further, when the bottom plate portion of the base body is provided with the water drainage hole, it is possible to promote the growth of the plant to be planted in the base body and maintain the appearance of the retaining wall in a good appearance.

Further, by providing the lower surface of the bottom plate portion with a positioning portion for positioning the lower soil blocking block at the upper edge of the side wall portion when stacking, the stacking work of the soil retaining blocks can be made more efficient and the soil retaining blocks can be made more efficient. It is possible to prevent mutual displacement and secure the strength of the retaining wall.

In this way, the earth retaining blocks 1 are stacked from bottom to top and the back plate 20 is attached to the earth retaining blocks 1, 1 at each stage.
By arranging the space between them, the retaining wall W of the slope A can be formed stepwise with good workability, and as shown by the alternate long and short dash line in FIGS. By filling said substrate 6 in the shape of soil with soil and planting plant J,
The appearance of the retaining wall W can be enhanced, which helps to beautify the environment. Moreover, since the retaining wall W is formed by arranging the earth blocking blocks 1 ... Evenly, the retaining wall W can be uniformly improved in strength.

The piles B are attached to the earth retaining blocks 1 at every other stage and at each stage, and at the same time as the slope A.
Soil C is filled in the space between the rear wall portion 5 of the soil retaining block 1 and the soil retaining block 1.

The ground R1 in front of the retaining wall W is located above the foundation F and fills the foundation F, and the ground R2 behind the upper end of the retaining wall W is at a height higher than 1 m from the ground R1. To position.

[0031]

As described above, the earth retaining block of the present invention is
Since it has an upper open container-shaped base, in addition to the new appearance added by this base itself, it is possible to enhance the appearance of the retaining wall by planting a plant in the base,
Useful for environmental beautification.

Further, since the rear wall portion of the base body is inclined substantially at the same inclination as the slope and the locking portion for supporting one end of the pile body supported on the slope is provided on the rear wall portion, the earth retaining block. Since it is possible to firmly support the structure, it is possible to increase the strength of the retaining wall, and since the back plate receiving groove is formed at the rear position of the side wall of the base body, the gap between the soil blocking blocks arranged side by side It can be easily shielded by a plate, and the workability can be improved in combination with stacking earth retaining blocks to form a retaining wall.

Further, by forming a water draining hole in the bottom plate of the base, it is possible to promote the growth of plants in the base and maintain an external appearance, and at the bottom surface of the bottom plate, a soil stopper block of the lower stage is formed. By providing the positioning portion for positioning the upper edge of the side wall portion, the work of forming the retaining wall can be made more efficient, and the positional deviation between the earth retaining blocks to be stacked can be prevented.
