Description

[Detailed Description of the Invention] The present invention relates to a greening block used for earth retaining walls for roads, railways, erosion control, and residential land development.

Various types of greening blocks have been invented and devised in the past, but in all of them, the bonding between the blocks was insufficient, and the backfilling of soil or concrete between the upper and lower blocks, as well as inside and behind the blocks, was insufficient. Due to earthquakes and vibrations, the connections between the blocks can easily come off, and when the connections come off, the connections between the blocks and the backfill are also insufficient, so the blocks can easily come apart. There was a drawback that if the blocks flew out or ■ blocks flew out, the whole would easily collapse and the purpose could not be achieved.

However, in the present invention, the bar plates are arranged opposite each other at regular intervals, the upper and lower middle portions of their rear ends are connected by a connecting part narrower than the height of the bar plate, and the front end of the bar plate is slanted diagonally upward. If the plates are integrally formed in a protruding manner and the distance between the centers of the bar plates is L, then the width of the inclined plate is 2L, a protrusion is formed on the top surface of the bar plate, and a position corresponding to the protrusion is placed on the bottom surface of the bar plate. By forming a recess in the block and stacking them to form a retaining wall, the soil within the block, between adjacent blocks, and on the back of the block are all integrated, and the space between the bars is consolidated. It becomes columnar and has strong shear resistance.
The individual blocks are well supported and stabilized, and the root hairs of the plants planted in the sloped board can extend not only to one block, but also to the lowest block and to the backfill. , it does not wither due to lack of moisture, and these root hairs also further integrate the soil, which also forms a strong retaining wall with strong shear resistance, eliminating the above-mentioned drawbacks. It is something.

To explain the structure with reference to the drawings, numeral 1 is a bar plate, which is approximately rectangular in shape, and is placed oppositely at a constant interval, and only the upper and lower center portions of the rear end are connected to the height of the bar plate 1. The inner surface of the connecting portion 2 is formed into a pointed portion 3 toward the center.

Reference numeral 4 denotes an inclined plate, which is integrally formed with the front end of the bar plate 1°1.

If the length between the centers of the rod plates 1 and 1 is L, then the inclined plate 4
The width is 2L.

Reference numeral 5 denotes a protrusion provided approximately at the center of the upper surface of the bar plate 1.

Reference numeral 6 denotes a recess provided on the lower surface of the bar plate 1 at a position corresponding to the projection 5.

7 is the basics.

Since the present invention has the above-mentioned structure, in order to construct it, the first stage is constructed on the foundation 7 by aligning the inclined plates 4 with their end surfaces butted against each other, and then the second stage is constructed. The tiers are arranged so that the upper surfaces of the adjacent bar plates 1, 1 of two adjacent blocks in the first tier are crossed, and the lower surfaces of the bar plates 1, 1 of one upper block are overlapped. They are stacked in the same direction and stacked one after the other in the same way.

Then, at the same time as filling soil into the bar plates 1 and 1 and the backs of the blocks, soil is also filled onto the inclined plate 4, and the inclined plate 4 is filled with soil.
Planting plants, etc. on the soil above will complete the construction.

In the block of the present invention, the upper and lower bars 1, 1 overlap each other over the entire width of the upper and lower surfaces of the bars 1, so that they can receive the load well, and the load is distributed in a pyramid shape, and the upper and lower blocks are
Since the protrusions 5 and the recesses 6 are fitted into each other, it can be easily constructed without requiring any special skills, and can be stacked up in an orderly manner to form a strong retaining wall. The upper and lower blocks will not collapse until the thickness of the bar plate 1 is removed.

Conventionally, this type of block has a bottom plate between the rod plates, but even if soil is filled between the bottom plates of the upper and lower blocks at the time of construction, the soil will become compacted over many years. As a result, a gap is created above each block (between the bottom plate of the upper block and the top surface of the soil of the lower block), and the soil between the upper and lower blocks is not integrated, making it weak against shear resistance. However, if the soil damage of the upper and lower blocks is not integrated, the plants planted in each level will not be able to absorb moisture from the soil of each level, resulting in a lack of moisture and withering. Also, the root hairs do not extend to the lower level, and the soil in the upper and lower blocks is not integrated by the root hairs, so this also has the disadvantage of being weak against shearing resistance.

However, in the present invention, there is a space between the bar plates 1 and 1, which is open at the top and bottom, and the connecting part 2 at the rear end of the bar plate 1 is also narrower in width than the height of the bar plate 1, and the center part is opened. Since only two blocks are connected, the soil between the rods 1 of all the blocks and the soil in the backfill are well combined and become one whole. It is compressed into a column-shaped consolidated state, which makes it strong against shear resistance, forming a strong retaining wall, and the individual blocks will not be thrown out by earthquakes or vibrations, and the inclined plate 4. As time passes, the roots of the plants planted on the top of the bar 1.1 spread from the soil between the rods 1.1 into the lower blocks and downwards, up to the bottom block, and into the connecting parts. It also penetrates into the backfill soil on the back of block 2, and as a result, the soil and backfill in all blocks are integrated by the root hairs, preventing the block from peeling off against the backfill, making it very strong. It serves as a retaining wall, and the plants etc. planted on the slope plate 4 can absorb not only the moisture in the soil on the slope plate 4, but also the moisture in the soil between the bars 1 and backfilling. This has the effect that the growth of plants will not be hindered by lack of moisture due to continuous sunny weather.

As shown in the drawing, the bar plate 1 is thickest at the center;
Make it a little thinner as you go up and down, and connect the connecting part 2.
By forming the inner surface of the retaining wall into a solid part 3 toward the center, the soil is applied to this sloped part, and the block receives not only the load of the block but also the load of the soil inside the block, so that the center of gravity of the retaining wall is By making the block production form a split mold from the horizontal center of the bar plate 1, the block to be formed can be easily removed from the form, reducing the number of defective products. can do.

Moreover, the number of divided pieces of the formwork can be reduced, the manufacturing cost of the formwork can be reduced, and handling can be facilitated.
