DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
An embodiment will be described. Reference numeral 1 denotes a sidewalk roadway boundary block body formed of concrete, which has a substantially T-shaped cross-sectional shape, and a concave portion 3 for vegetation of moss and vegetation, which will be described later, is formed on the upper surface of the standing boundary block portion 2. It is formed.

Then, on the wall surface forming the recess 3,
A water retention body 4 made of a material having good water retention, for example, made of a brick or a porous ceramic material (soft ceramics, etc.) in consideration of drying due to a decrease in rainwater.
However, various types of adhesives may be used, or they may be bonded by various bonding methods.

A plurality of water-permeable pipes 6 made of synthetic resin or metal are provided at predetermined intervals on the bottom surface of the concave portion 3 so as to open water-permeable holes communicating with the soil 5 below the main body 1 of the walkway boundary block. And are formed integrally. In this case, the permeable pipe 6
Is extended to the outside of the sidewalk boundary block body 1. The soil 5 below the pedestrian road boundary block main body 1 is made of, for example, a brick or a porous ceramic material (soft ceramic, etc.) which has good water retention to absorb rainwater and the like through the water permeable pipe 6. The water retaining body 7 formed of the lump is disposed.

In the water-permeable pipe 6, both ends extend to the concave portion 3 and the water retaining body 7, and are made of, for example, a glass fiber body, gauze, or a highly water-absorbing resin (such as a crosslinked sodium polyacrylate). By inserting the water absorbing body 8, the water retained in the water retaining body 7 can be sucked up by capillary action. In this case, the water permeable pipe 6
The lower end is brought into contact with the water retaining body 7 through the water absorbing body 8 made of the glass fiber body, gauze or highly water absorbent resin,
An opening 6A for drainage is opened in the water-permeable pipe 6.

When the water permeable pipe 6 is made of a brick having good water retention properties or a porous ceramic material (soft ceramics or the like), the water absorption pipe 8 is not necessarily used by directly contacting the water retention body 7. May be used, but may be used. Further, as the water retaining body 7, a water absorbing body made of the above-described high water absorbing resin may be used.

Further, since the recesses 3 are formed and thus weakened, the remaining portions 1A of the boundary block 2 where the recesses 3 are formed are extended to the bottom 1B with a predetermined interval. The extending reinforcing bar 9 is buried. in this case,
If necessary, the reinforcing bar 9 may be buried in the remaining portion 1A or the bottom portion 1B vertically and horizontally.

The pedestrian road boundary block main body 1 thus formed is installed so as to be connected to the boundary between the sidewalk 10 and the roadway 11, and the soil 1 is placed in the recess 3 of the pedestrian road boundary block main body 1.

The pedestrian road boundary block main body 1 is manufactured by stamping and molding concrete using a mold.

According to the first embodiment described above, when the rain falls, the soil 1 in the sidewalk boundary block main body 1 is removed.
When the water permeating the water 2 exceeds the water retention capacity, the water is discharged out of the sidewalk boundary block main body 1 through the opening 6A of the water permeable pipe 6 and is retained by the water retaining body 7. Accordingly, it is possible to prevent the moss and plants such as sedges, ferns, yaburan, and janowhisker 13 from decay, and the roots of the evergreen perennial herbs are kept rotting.

Further, even if the day when it does not rain continues, the water retained in the water retaining body 7 is sucked up by the water absorbing body 8 made of glass fiber, gauze or highly water-absorbing resin due to the capillary phenomenon, and the soil 12 is removed. Since the moisturizing state is maintained, the wisdom beard 13 and the like are prevented from withering.

Since the glass fiber body, the water absorbing body 8 made of gauze or a highly water-absorbing resin, and the water retaining body 4 also retain water, the soil 12 remains moist. Further, by forming the water-permeable pipe 6 from a brick having good water retention and a porous ceramic material,
The moisturized state lasts longer.

Next, a second embodiment will be described with reference to FIG. The second embodiment is an example in which a water storage tank 14 is used in place of the water retaining body 7 of the first embodiment. An example in which the sidewalk roadway boundary block body 1 is installed on concrete 15 is described. It will be described as.

That is, a tank 14 made of a synthetic resin material for storing rainwater or the like is buried in the concrete 15 below the pedestrian road boundary block main body 1 through the water permeable pipe 6, and slightly below the bottom of the tank 14. The lower end of the water-permeable pipe 6 is arranged at a position separated from the water-permeable pipe 6. An opening 14A is formed in the upper part of the side surface of the box-shaped tank 14, and the opening 14A communicates with a drain passage 16 communicating with the soil 5 formed in the concrete 15.

Further, water absorption made of, for example, a glass fiber body, gauze, or a highly water-absorbing resin (such as a crosslinked sodium polyacrylate) extends into the water-permeable pipe 6 at both ends extending to the recess 3 and the tank 14. By inserting the body 8, the water stored in the tank 14 can be sucked up by capillary action.

According to the second embodiment described above, when the rain falls, the soil 1 in the sidewalk boundary block main body 1 is removed.
When the amount of water permeated into the tank 2 exceeds the amount that can be retained, the water is stored in the tank 14 through the water-permeable pipe 6,
The overflowing water flows through the opening 14A and the drain passage 16 to the soil 5
Drained inside. Therefore, rainwater remains stored in the concave portion 3 and the moss and plants such as sedge, fern,
It is possible to prevent the roots of Yabulan or Janohige 13 from rotting.

Further, even if the day when it does not rain continues, the water stored in the tank 14 is sucked up by the water absorbing body 8 made of glass fiber, gauze or superabsorbent resin by the capillary phenomenon.
Since the soil 12 is kept moist, it is possible to prevent the wisdom beard 13 and the like from withering.

Further, even if the water in the tank 14 is exhausted, the water absorbing body 8 and the water retaining body 4 made of a water absorbing resin can be used.
Therefore, the soil 12 remains moist. Further, the water-permeable pipe 6 is made of a ceramic material having good water retention, such as a brick or porous ceramic material, so that the moisture-retaining state is maintained for a longer time.

Next, a third embodiment will be described with reference to FIG. The third embodiment is an example in which a tank 17 is buried in a main body 1 of a sidewalk boundary block.
In this embodiment, the water overflowing from the drain 7 is drained to the roadway 11 through the opening 17A and the drain passage 18. Also, sometimes, rainwater flows from the roadway 11 into the tank 17 through the passage 18,
Water may be stored.

This embodiment is particularly effective when the pedestrian block 1 is placed on concrete 15 and there is no soil 5 below.

According to the embodiment described above, soil 12 and fertilizer are buried in the recess 3 of the main body 1 of the pedestrian-walkway boundary block, and moss and vegetation such as sedge, fern, yaburan, and janoge 13 are evergreen perennials. Because we vegetate herbs,
It is easy on the scenery and softens car drivers and pedestrians.

Further, since evergreen perennial herbs such as sedge, fern, yaburan and scabbard 13 are vegetated, they do not die throughout the year, so oxygen is generated from carbon dioxide by photosynthesis and suppresses global warming. effective. Furthermore, it promotes the action of adsorbing and decomposing various pollen and automobile exhaust gas, and is friendly to people and the earth.

Since the water retaining body 4 made of a porous ceramic material is provided on the wall surface forming the concave portion 3, it has an effect of retaining water when there is rainwater. Is easy.
