[Problems to be solved by the invention]
However, in the conventional block as described above, there is no irrigation means for the planting recess, and in order to prevent the soil in the recess from drying and the accompanying death of vegetation, etc. In many cases, it is required to perform frequent irrigation, and maintenance and maintenance of vegetation and the like may be required.
[0005]
In view of the conventional problems as described above, it is an object of the present invention to provide a pedestrian boundary block that can easily maintain and manage plants and the like planted on the upper surface of the block.
[0006]
[Means for Solving the Problems]
The present invention is a pedestrian boundary block having a block body in which a planting recess opening upward is formed on the upper surface.
A drainage passage penetrating in the longitudinal direction is provided inside the block main body, and at least a region between the drainage passage and the planting recess is constituted by a continuous void composition. Is.
[0007]
In the pedestrian road boundary block configured as described above, the water collected in the drainage passage penetrates the continuous void composition and is sucked up to the planting concave portion, so that the situation of soil drying can be determined. Without looking around and frequent irrigation, it is possible to prevent soil drying in the recesses and the death of plants planted in the recesses, and it is possible to easily maintain and manage these plants.
[0008]
Moreover, in the pedestrian road boundary block, it is preferable to provide water guide means for guiding water from a side portion of the block main body to the drainage passage.
In this case, the water guiding means guides water such as rain water from the side portion of the block main body to the drainage passage, so that the water sucked up to the planting concave portion side can be ensured more reliably.
[0009]
In the pedestrian road boundary block, the planting recess may include a plurality of openings that are open at predetermined intervals in the longitudinal direction on the upper surface of the block body.
In this case, since the aperture ratio on the upper surface of the block body is suppressed, a decrease in strength in the block body due to the opening of the planting recess can be suppressed, and a high-strength pedestrian boundary block can be configured. .
[0010]
Moreover, the said pedestrian road boundary block WHEREIN: The said planting recessed part opened continuously so that the upper surface of the said block main body might be connected between the both ends of a longitudinal direction.
In this case, it becomes easy to form the planting recess in the block main body, and the molding of the walking road boundary block can be simplified.
[0011]
Moreover, in the pedestrian road boundary block, it is preferable that the lower cross-section and the upper cross-section of the block body are made of ordinary concrete and porous concrete, respectively.
In this case, it is possible to suppress water leakage from the lower portion of the cross section configured using ordinary concrete to suppress the outflow of moisture from the drainage passage, and from the upper section of the cross section configured using porous concrete to the side of the planting recess It becomes possible to easily supply moisture to the plant, and the maintenance work for the vegetation in the recess can be simplified.
[0012]
In the walking road boundary block, a dam member may be provided at a lower section of the drainage passage.
In this case, the water in the drainage passage can be temporarily retained by the dam member.
[0013]
Moreover, in the said walkway boundary block, it is preferable to provide a water absorption means in the area | region between the said drainage channel and the said planting recessed part, and to move the water | moisture content in a drainage channel to the planting recessed part side by this water absorption means.
In this case, the water absorption means can easily promote moisture movement from the drainage passage to the planting recess side, and can more easily prevent soil drying and death of plants and the like.

In the planting recess 3, a bottom 3 a having a substantially rectangular cross section formed so as to penetrate the ground protrusion 4 in the longitudinal direction and a top surface 2 a of the block body 2 are opened in a circular shape at predetermined intervals in the longitudinal direction. A plurality of, for example, five openings 3b are included. The inside of the bottom 3a and the opening 3b of the planting recess 3 is filled with the soil of the green space G, and as shown in FIG. 1, stems and leaves protrude from the upper surface 2a of the block 1 Plants such as vegetation in the green space G are planted in the soil.
Moreover, the soil put in this planting recessed part 3 is maintained by the continuous space | gap composition under the said recessed part 3. FIG. Furthermore, the composition of the soil, gravel, clay material, etc. is selected so that this soil can retain moisture such as rainwater that has permeated directly from the opening 3b or indirectly through the continuous void composition. And function as a water retention material. In addition, the structure which provides a net | network (net | network) etc. in the bottom part of the planting recessed part 3 and performs the maintenance of the soil in the planting recessed part 3 more effectively besides this description may be sufficient.
[0020]
In the pedestrian road boundary block 1 of the present embodiment configured as described above, moisture such as rainwater collected in the drainage passage 6 passes through the continuous void composition below the planting recess 3 and enters the planting recess 3. Since it permeates into the soil of the green part G, it is possible to prevent the soil from drying without carrying out much irrigation work on the green part G, and also to prevent the plants planted in this soil from dying. it can. Further, in this continuous void composition, since the root of the plant is configured to be able to enter, the plant can directly take in moisture from the drainage passage 6, and the plant itself can prevent death due to soil drying. Yes. As a result, unlike the conventional example described above, the maintenance work of the green area G is simplified and the maintenance and management of the green area G is facilitated without performing a patrol for frequent situation such as soil drying and frequent irrigation. It can be carried out.

Further, in this embodiment, the water guide groove 7, the water collection hole 8, and the water injection hole 9 for guiding water such as rainwater from the side portion of the block body 2 are provided in the drainage passage 6. Water such as rainwater can be efficiently moved to the drainage passage 6, and such water can be effectively utilized as irrigation for the green space G. In addition, since the water used for cleaning the roadway 50 can be poured into the drainage passage 6, the roadway 50 can be cleaned and the green area G can be irrigated at the same time. -Management can be made easier.
Moreover, in this embodiment, since the opening part 3b of the planting recessed part 3 is formed by opening the upper surface 2a at predetermined intervals in the block longitudinal direction, the aperture ratio on the upper surface 2a can be reduced. it can. As a result, it is possible to configure a strong pedestrian boundary block 1 that suppresses strength reduction due to the planting recess 3 in the block body 2.
