Description

[Detailed description of the invention] "Industrial application field" This invention is a retaining wall that is characterized by having a large open front when stacked, and the inside being filled with earth and sand to allow plants to grow. This relates to blocks for use.

``Prior Art'' There are various types of greening blocks of this type in the past, but one example is to provide an upwardly sloped section at the front end of the horizontal section, and to install an appropriate surface on the upper surface between the horizontal section and the sloping section. Two vertical walls are installed in the interval, and a back wall is formed behind them.In construction, the horizontal part and the sloped part of the adjacent blocks are matched, and at the same time, they are stacked upwards. As a result, the front of the slope is left open, and the inside is filled with earth and sand and plants are planted therein.

``Problems that the invention aims to solve'' In the above-mentioned block, the space to be filled with earth and sand is independent, and each block must be filled with earth and sand, which is time-consuming, and depending on the structure. There was also concern that water would accumulate inside the plant and cause root rot. In addition, when the front slope was constructed, the slope continued in the extension direction, making the whole landscape monotonous.The space to fill with earth and sand was small, and naturally the amount of earth and sand filled was small, and the roots were damaged. There were inconveniences such as not being able to grow large plants.

"Means for Solving the Problems" Therefore, the present application has been proposed to solve the above-mentioned disadvantages, and its configuration is such that the horizontal part of a certain length has an upward slope in front of the front end. a side wall portion is provided at both ends of the side wall portion, the side wall portion is elongated slightly farther back than the horizontal portion, a protrusion is formed on the upper surface thereof, and an engaging recess is formed on the lower surface symmetrically with the protrusion, On the outside of the side wall, there is a receiving part on the horizontal line.
A recess is formed in the rear part. To construct this, the space between adjacent blocks must be approximately 1 block.
A large number of blocks are lined up in parallel with gaps for individual blocks, and the upper block is sequentially stacked over the two blocks by engaging the protrusion and the engagement recess. When piled up in this way, there is a gap between the rear of the horizontal part and the retaining wall surface, so if you fill the piled earth and sand from above, it will fill up to the bottom, and excess water will stagnate on the way. Since the water is drained downward without causing root rot, and the space between the blocks can be widened and a large amount of earth and sand can be filled, it is possible to grow plants of a certain size.

Next, the structure will be explained with reference to the drawings. Reference numeral 1 denotes a horizontal portion of a certain length, and following this, a sloped portion 2 is formed at the front end. Reference numeral 3 denotes a side wall portion that is integrally provided on both sides of the horizontal portion 1 and the inclined portion 2, and is provided slightly longer and further rearward than the horizontal portion 1. 4 is a protrusion provided on the upper surface of the side wall portion 3. Reference numeral 5 denotes an engagement recess provided on the lower surface of the side wall portion 3, which is provided at a symmetrical position to the protrusion 4;
When stacked, they engage with the protrusion 4 of the lower block. Reference numeral 6 denotes a receiving portion provided on the outside of the side wall portions 3, 3, and is provided on an extension line of the horizontal portion. 7 is a recess provided at the rear of the receiving portion 6. Reference numeral 8 denotes a block which is used in conjunction with the horizontal part 1 and the inclined part 2, and is composed of a horizontal part 1' and an inclined part 2' having the same cross section as the horizontal part 1 and the inclined part 2. 9 is earth and sand to be filled. 10 is the basics.

``Function'' Since the present invention has the above-mentioned structure, the first stage block is the base 1, as shown in Fig. 7.
0, a large number of blocks are placed on top of the block with an interval of about one block between the blocks, and then in the second stage, one block is placed across two blocks in the first stage. The mating recesses 5, 5 are engaged with the protrusions 4, 4 of two adjacent blocks in the first stage, and are sequentially stacked up to the second stage, third stage, and so on. And if necessary, the receiving part 6 of the adjacent block
The horizontal portion 1' of the block 8 used together is placed and engaged in the recessed portion 7. Further, the inside of the block pile is filled with earth and sand 9, and plants such as plants are planted in the earth and sand 9.

"Effect of the invention" The structure of the invention is stacked as described above, and when the earth and sand 9 is filled from the top of the stacked blocks, a space is created behind the horizontal part 1 between the retaining wall surface and the earth and sand 9. The soil 9 falls to the bottom, making it easy to fill with soil 9, and since the soil 9 is integrated into the upper and lower parts, unnecessary water permeates downward and is discharged, preventing excess water from accumulating and allowing plants to grow. Root rot does not occur, and the inside of the block pile is large and can store a large amount of soil 9, and since the soil 9 is connected to the top and bottom, it is possible to grow some large plants. In addition, since the upper and lower protrusions 4 and the engaging recesses 5 of the block of the present invention engage with each other, a single block does not jump out randomly, and the load is distributed over the pyramid. The roots of the retaining wall can penetrate into the rear retaining wall surface to form a strong retaining wall, and can be stacked up by engagement between the projections 4 and the engaging recesses 5, making construction easy and shortening the construction period. Also, if a small space is required depending on the type of plant, use block 8.
This has the advantage that it can be formed by being built over the receiving part 6 and recess 7 of an adjacent block as shown in the first stage and the top stage shown in FIG.
