Had become something. Further, Japanese Utility Model Laid-Open No. 53-125207 proposes a block provided with a bucket portion on the front surface which can be vegetated for the purpose of greening. However, in the block described in the above publication, the bucket portion is simply filled with soil or the like and vegetated, and the water supplied to the soil is only rainwater, so that sufficient water can be supplied to the vegetated plants. They will die without them.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned drawbacks and problems, and has a notch formed on the outer surface of both sides of the front end of a front frame having a vertically extending through portion. And a concrete block for retaining wall formed by projecting a soil receiving portion at the center lower portion of the front end of the through portion of the front frame portion and further connecting a rear portion behind the front frame portion, and The present invention relates to a retaining wall using a concrete block, wherein the concrete block is laid and constructed, and the lower end of the opening of the penetrating portion of the block located on the upper side is closed by the front frame of each of the adjacent blocks. A part of the upper end of the penetrating portion of the block located below is opened by the notch of each of the blocks adjacent to each other, and the soil for planting is filled in the penetrating portion.

[0006]

Therefore, in a retaining wall constructed by stacking and constructing a block, the penetrating portion of the block filled with soil for planting has a lower end, a soil receiving portion protruding from the lower center of the inner front end. And the front blocks of the adjacent blocks located on the lower side, so that the filled soil does not flow out.

[0007] The upper end of the penetrating portion of the block is closed by the front frames of the adjacent blocks located on the upper side by fabricating the upper block, but is partially closed by the respective cutouts. Is open.

[0008] Accordingly, in the above-described block fabric construction state, a part of the upper end of the penetrating portion of the block is opened, and the filled soil faces the outside. Trees and flowers are vegetated on the soil. The front of the constructed retaining wall is greened by plants, and the landscape is extremely excellent. In addition, if there is a groove for accommodating the water supply pipe on the upper surface of the retaining part and the retaining wall is constructed, groundwater from the slope will be supplied to the vegetated soil, so the plants will die even without rainfall There is no.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a concrete block for a retaining wall according to the present invention; FIG. It is configured.

The front frame 2 has, for example, a substantially trapezoidal shape in plan view, with the short side of the trapezoid being the front side and the long side being the back side, and a through portion 5 is opened in the vertical direction. A notch 6 is formed on the outer surface of the portion, and a soil receiving portion 7 is formed in a substantially triangular pyramid shape at the lower center of the front end of the inner surface of the front frame 2.
Is protruding. The front frame portion 2 is not limited to a substantially trapezoidal shape in a plan view, and may have any configuration as long as the penetrating portion 5 is opened in the up-down direction and the cutout portions 6 are formed on the outer surfaces on both sides of the front end.

The thickness of both sides of the front frame portion 2 is approximately half the width of the right and left sides of the through portion 5, and a decorative pattern is engraved on the front surface.

A recess 3 projecting from the rear surface of the front frame 2 is a thick plate in the vertical direction, and a rear portion of the thick plate is formed at the rear end of the recess 3 so as to be orthogonal to the recess 3. 4 are continuously provided, and a groove 8 is formed on the upper surface of the retaining portion 3 so as to gradually increase in depth toward the rear portion of the front frame portion 2.

The retaining wall 9 is constructed by laying the concrete block 1 having the above-described configuration on a slope or the like, and the thickness of both sides of the front frame 2 is approximately half of the left and right width of the through portion 5. Therefore, the lower end of the penetrating portion 5 of the block 1 located on the upper side is connected to the side of the front frame portion 2 of each of the left and right adjacent blocks 1 located on the lower side, and the block 1 located on the upper side.
It will be closed by the soil receiving part 7 of itself.

Therefore, the structure of the soil receiving portion 7 may be any structure as long as it can fill the gap formed by the notch 6 of each front frame portion 2 of the adjacent block 1, and in particular, the triangular pyramid shape described above. However, the present invention is not limited to this.

On the other hand, the upper end of the opening of the through portion 5 of the block 1 located on the lower side is partially closed by the side of each front frame 2 of the adjacent block 1 located on the upper side. The other part is opened by the gap formed by the notch 6. Therefore, by filling the penetrating portion 5 with planting soil, trees and plants can be vegetated and grown outward from the open portion.

FIG. 1 shows a concrete block 1 according to the present invention.
Is a longitudinal section of a state in which a retaining wall 9 is constructed by laying cloth in an inclined manner along a slope, and a pipe for supplying water from the penetrating portion 5 filled with soil for planting to the slope. The front end of the pipe 10 is housed and positioned in a groove 8 formed from the upper surface of the retaining portion 3 to the rear of the front frame 2. Therefore, the underground water from the slope flows through the pipe 10 to the through portion 5, so that the soil filled in the through portion 5 can be irrigated.

As shown in FIG. 8 and subsequent figures, insertion holes are respectively formed in the upper and lower surfaces of each rear side of the front frame 2 of the concrete block 1, and pins 11 are protruded and embedded in the insertion holes. In other words, this pin 1 is attached to the inner inner surface of each penetrating portion 5 of the adjacent block 1 located on the upper side.
1 is locked, and the stacking strength of the upper and lower concrete blocks 1 can be increased.

Further, when the concrete block 1 is laid in a fabric, if the net 12 is arranged to extend rearward between the upper and lower blocks 1, the pressure of the soil can be reduced by the net 12. Therefore, it is not necessary to cast concrete into the space formed between the respective retaining portions 3 of the adjacent blocks 1, and the stability of the retaining wall can be maintained by simply filling the soil.

When such a net 12 is provided, if the above-described pin 11 is provided in a protruding manner, the net 12 can be hooked on the pin 11, thereby simplifying construction and construction.
The strength of the retaining wall can be further increased.

As described above, the present invention has been described based on the embodiments in the drawings. However, the present invention is not limited to the above-described embodiments, and may be any method unless the structure described in the claims is changed. Can be implemented.

In summary, according to the present invention, notches are formed in the outer surfaces of both sides of the front end of a front frame portion having a vertically extending through portion, and a central lower portion of the front end of the through portion of the front frame portion. And a rear part is continuously provided via a stay part behind the front frame part, and a groove for accommodating a water supply pipe is formed on an upper surface of the stay part. Since it is a wall concrete block, trees and the like can be vegetated in the penetrating portion, and the vegetated trees and the like can be constantly irrigated with a water supply pipe. Then, the blocks are stacked and constructed, and the lower end opening portion of the penetrating portion of the block located on the upper side is closed by the front frame portion of each of the adjacent blocks together with the soil receiving portion, and each of the adjacent blocks is closed. A cut-out on the side of the front frame part opens part of the upper end of the penetrating part of the block located below, fills the penetrating part with soil for planting, and has one end positioned on the slope. The other end of the pipe is housed in the groove of the reserve part and faces the soil filled in the penetration part to construct a retaining wall, so that the front part of the retaining wall fills the penetration part whose lower end is closed Plants such as trees and flowers grown by the planting soil that has been grown grow outside from the open portions formed by the respective notches between adjacent blocks, and green the outer surface of the inorganic concrete block. Can be excellent Landscapes can provide, especially those which exhibits an excellent effect in the region to respect the mountains and nature. Moreover, the soil in the penetrating portion is in a wet state because groundwater on the slope can be supplied by a water supply pipe.
