BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boundary block laid at a boundary between a pavement zone such as a roadway or a plaza and a tree planting zone.

[0002]

2. Description of the Related Art Heretofore, this type of boundary block has been a nonporous rectangular parallelepiped block formed of concrete. As shown in FIG. 8, a plurality of the boundary blocks 100 are laid on the boundary between the sidewalk 102 on which the tree planting zone 101 is provided and the pavement zone 105 such as a roadway. 105 is partitioned. Therefore, rainwater or the like that has fallen on the pavement zone 105 is blocked by the boundary block 100,
After passing through the collecting / draining channel 106, the water is discharged from a drain port (not shown) to sewage or the like.

[0003]

However, the above-described conventional boundary block 100 is formed of a nonporous rectangular parallelepiped block made of concrete, and blocks all rainwater and the like on the pavement zone 105. There was a problem.

[0004] Since the tree planting zone 101 is surrounded by the boundary block 100 and the curb 103, when it rains, the rainwater falling on the tree planting zone 101 is absorbed by the tree planting zone 101 and supplied to the water supply of the tree planting 104. However, rainwater that has fallen on the pavement zone 105 is discharged to the sewage and the like as described above along the drainage channel 106. That is, since the supply of water to the tree planting 104 depends only on rainwater falling on the tree planting zone 101, the amount of water stored in the tree planting zone 101 is limited. For this reason, if the sunshine continues, the tree planting zone 101 may dry up in a short time and the tree planting 104 may die.

[0005] In order to prevent such a situation, a method of spraying water into the tree-planting zone 101 by using a watering wheel at the time of sunshine is adopted. However, an increase in the operation cost becomes a problem. The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a boundary block capable of supplying water from a pavement zone to a tree planting zone.

[0006]

To achieve the above object, the present invention according to claim 1 is provided at a lower part of a block body in a boundary block disposed at a boundary between a pavement zone and a tree planting zone, The block body has one or more water supply grooves that open to the surface facing the pavement zone and the surface facing the tree planting zone to guide water on the pavement zone toward the tree planting zone.

The present invention according to a second aspect of the present invention is characterized in that, in the first aspect, a porous member for stopping foreign matter from the pavement band side is detachably attached to the water supply groove.

[0008]

According to the boundary block of the first aspect,
Since one or more water supply grooves are provided at the bottom of the block body, rainwater, etc., collected near the boundary block flows in from the pavement-side opening of the water supply groove and flows out from the tree-planting side opening to the tree planting zone. Then, water supply to the tree planting zone is performed.

Further, according to the boundary block of the present invention, since the porous member is detachably attached to the water supply groove, foreign matter such as garbage entering the tree planting zone from the pavement zone can be removed. Stopped by the porous member, only rainwater or the like flows into the planting zone. Therefore, foreign substances such as dust can be removed by removing the porous member caught by the foreign substances from the water supply groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the present invention will be described. FIG. 1 is a perspective view showing a boundary block according to a first embodiment of the present invention, FIG. 2 is a front view of the boundary block,
FIG. 3 is a side sectional view thereof. In FIG. 1, reference numeral 1 denotes a boundary block according to the present embodiment. The boundary block 1 has a configuration in which a water supply groove 20 is provided in a block body 10.

The block body 10 is formed by solidifying concrete into a substantially rectangular parallelepiped shape, with the surface 11 facing the pavement zone 80 such as a road or a park square facing the front, and the surface 12 facing the tree planting zone 90 facing the back. I have. Its both sides 13
As shown in FIG. 3, it is formed in a substantially trapezoidal shape with a slightly lower width, and a chamfer having an R is formed on an upper portion of the front surface 11. The outer diameter of the block body 10 is set based on the Tokyo Metropolitan Standard. That is, as shown in FIG. 2, the length L of the block body 10 is set to 600 mm, and the height H is set to 200 mm.

On the other hand, the water supply groove 20 is provided in the pavement zone 8 shown in FIG.
It is a groove for guiding the water on the 0 side to the tree planting zone 90 side, and is formed by cutting out the lower part of the center of the block body 10. The water supply groove 20 is provided at the lower central portion of the block
The opening 21 and 22 have a substantially U-shaped cross section on the front and back sides. Specifically, as shown in FIG.
0 denotes both side walls 23 and 2 which are inclined so as to spread slightly downward.
3 and a semicircular top wall 24, and the height N
Is set to 80 mm, and the diameter P of the ceiling wall 24 is set to 40 mm.

Next, the operation of the boundary block 1 having such a configuration will be described. First, as shown in FIG.
A plurality of boundary blocks 1 are laid in series on the boundary between the pavement zone 80 and the tree planting zone 90 with the front surface 11 facing the pavement zone 80 side. Then, the contact portions of the side surfaces 13 of the adjacent boundary blocks 1 are filled with medimortar or the like to maintain the liquid tightness between the boundary blocks 1. Thereafter, the pavement of the pavement zone 80 is formed so as to be inclined downward toward the front surface 11 of the boundary block 1, and the drainage channel 81 of the pavement band 80 is formed near the front surface 11 of the boundary block 1. At this time, as shown in FIG. 2 and FIG. 3, the collection / drainage channel 81 is formed such that the surface of the collection / drainage channel 81 abuts at a position of the height Q (for example, 30 mm) from the lower surface of the boundary block 1. In addition, soil is piled up in the tree planting zone 90. As a result, most of the rear surface 12 has a tree planting zone 9.
Boundary block 1 is buried in soil
The mortar or the like descends and enters the water supply groove 20, which is located on a boundary between the tree planting zone 0 and the tree planting zone 90.

When the boundary block 1 is laid at the boundary between the pavement zone 80 and the tree planting zone 90, the rainwater A on the pavement zone 80 flows along the slope and collects in the drainage channel 81 during rainfall. At this time, as shown in FIGS. 1 and 3, since the front opening 21 of the water supply groove 20 of the boundary block 1 faces the collection / drainage channel 81, the rainwater A collected in the collection / drainage channel 81 is indicated by an arrow. As shown, it flows into the water supply groove 20 from the front opening 21. Then, the rainwater A flows out of the rear opening 22 into the tree planting zone 90 through the water supply groove 20.

That is, a large amount of rainwater A that has fallen on the pavement zone 80 is supplied by the water supply groove 20 of the boundary block 1.
Since it is guided to 0, the tree planting zone 90 is supplied not only with the rainwater directly falling on the tree planting zone 90 but also with a large amount of rainwater A falling on the pavement zone 80. Therefore, in the tree planting zone 90 on which the boundary block 1 is laid, a much larger amount of water is stored than in the conventional tree planting zone 101 described above. Can be continuously supplied to the tree planting 91 without losing water. As a result, it is possible to omit the operation of moving the watering truck by mobilizing the workers every time the sun is shining, and it is possible to reduce the operation cost.

Next, a second embodiment of the present invention will be described. FIG. 4 is a perspective view showing a boundary block according to the second embodiment of the present invention, and FIG. 5 is a side sectional view of the boundary block according to the embodiment. The boundary block 2 of this embodiment differs from the first embodiment in that the porous member 30 is inserted into the water supply groove 20.

The porous member 30 is a water-permeable rod formed by entanglement of a nylon wire, and is removably inserted into the water supply groove 20 of the block body 10. With such a configuration, only the rainwater A from the pavement zone 80 side is
The garbage B such as a leaf that has passed through the inside 0 and is carried by the rainwater A is caught on the tip of the porous member 30. Therefore, when a certain amount of dust B is caught on the porous member 30, the porous member 30 is taken out of the water supply groove 20, and the attached dust B is removed from the porous member 30, so that the dust B is transferred to the tree planting zone 90. Smooth water supply can be maintained.

That is, as shown in FIG.
Is covered with the soil of the tree-planting zone 90,
When the porous member 30 is not inserted into the water supply groove 20, the trash B carried by the rain water A
There is a possibility that the water supply groove 20 may be clogged up on the second side. However, by providing the porous member 30 as in the present embodiment, dust B can be hooked on the porous member 30 and removed, and clogging of the water supply groove 20 can be prevented. The other configuration, operation, and effect are the same as those of the first embodiment, and the description thereof is omitted.

Finally, a third embodiment of the present invention will be described. FIG. 6 is a perspective view showing a boundary block according to a third embodiment of the present invention, and FIG. 7 is a side sectional view of the boundary block according to the embodiment. This embodiment is different from the first and second embodiments in that the porous member 40 is detachably attached to the front opening 21 of the water supply groove 20.

The porous member 40 provided in the boundary block 3 of this embodiment is a lattice-shaped metal fitting whose outer shape is set according to the shape of the front opening 21. On both sides of the porous member 40, a pair of leaf springs 41 which are engaged with the side wall 23 of the water supply groove 20 are provided in a protruding manner. On the other hand, on the periphery of the front opening 21 of the boundary block 3, a mounting groove 25 for fitting the porous member 40 is formed. Then, as shown in FIG. 7, the porous member 40 is fitted into the mounting groove 25 in a state where the leaf spring 41 is pressed into the front opening 21.

With such a configuration, the water supply groove 2 for the garbage B
0 can be stopped by the porous member 40 to prevent the water supply groove 20 from being clogged.
Is attached to the front opening 21, so that the porous member 40 can be quickly removed. The other configuration, operation, and effect are the same as those of the first and second embodiments, and thus description thereof is omitted.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, in the above embodiment, the outer diameter of the block main body 10 is set according to the Tokyo Metropolitan Government standard, but may be set larger according to the Ministry of Construction standard. Further, although the block main body 10 is formed of concrete, the present invention is not limited to this, and the block main body 10 may be formed of a material capable of maintaining the same or higher strength as the concrete. Further, although the water supply groove 20 is formed at the center of the block body 10, the water supply groove 20 may be formed at a position shifted from the center of the block body 10. In addition, the height of the water supply groove 20 is set to 80 mm, and the diameter of the ceiling wall 24 is set to 40 mm. However, various dimensions can be set as long as the strength of the block body 10 can be maintained. Further, although the cross section of the water supply groove 20 is substantially inverted U-shaped, it is needless to say that various cross-sectional shapes such as a triangular shape and a quadrangular shape can be adopted.
In the above embodiment, one water supply groove 20 is provided. However, a plurality of water supply grooves 20 can be formed as long as the strength of the block body 10 can be maintained.
