(First embodiment)
Hereinafter, a first embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, a roadbed 12 made of mortar is formed on a roadbed 11. On the upper surface of the roadbed 12, a plurality of rectangular flat pavement panels (hereinafter simply referred to as panels) 14 made of PC concrete or RC concrete are laid in a grid pattern, and joints 16 between the panels 14 are joints. Mortar is filled as the material 16a. Thus, a paving stone pavement 10 such as a pavement is configured.

  As shown in FIG. 3, a recess 14 a is formed on the surface of the panel 14. The recess 14 a is formed by four triangular surfaces with the outer edge of the panel 14 as the bottom. In addition, the depth of this hollow part 14a may be about 5-10 mm when the external shape of the pavement panel 14 is (300) x (300) mm, for example. In the center of the panel 14, a water distribution port 15 having functions of water supply and drainage is provided. On the back surface of the panel 14, a water guide channel 20 having a semicircular cross section is formed in a planar cross shape that intersects at the center of the panel 14. Each water conduit 20 of the adjacent panel 14 is connected by a sheath tube 17 as a joint. As shown in a circle S in FIG. 2A, the sheath tube 17 is embedded in the joint material 16 a with a boss-like projection 17 a formed on the outer periphery regulating the opening width of the joint 16. As shown in a circle S in FIG. 2B, a pair of ribs 17b may be provided instead of the boss-shaped protrusions 17a. A portion where the water conduit 20 intersects and the water distribution port 15 communicate with each other.

  As shown in FIGS. 4A and 4B, the water distribution port 15 is configured as follows. That is, in the center of the panel 14, a hollow cylindrical female screw body 41 having a flange portion 42 on the outer periphery and a female screw formed on the inner surface is embedded. The base 25 is composed of a cylindrical base 26 and a flange portion 27 on which a male screw that is screwed into the female screw is formed. A stainless strainer 28 is attached to the recess 27 a of the flange portion 27 of the base 25. In addition, concave portions 29 are formed at four locations on the outer edge portion of the flange portion 27. The base 25 can be rotated by applying a tool (not shown) to the recess 29. And the water of the water conduit 20 is supplied to the hollow part 14a of the panel 14 through the nozzle | cap | die 25 of the water distribution port 15. FIG.

Next, a configuration for supplying water to the paving stone pavement 10 of the present embodiment and discharging water from the recessed portion 14a will be described.
As shown in FIG. 5, an adjustment tank 30 and a water storage tank 31 are provided in the vicinity of the paving stone pavement 10. The water conduit 20 and the adjustment tank 30 are connected by a pipe S1.

  When the water level sensor 34 of the water storage tank 31 detects that the water level in the tank 31 is lower than a predetermined value, the on-off valve V3 is opened and water from a water source (not shown) is connected via the pipe S5. Is supplied into the water storage tank 31. When the water level sensor 34 detects that the water level in the water storage tank 31 is higher than a predetermined value, the on-off valve V2 is opened and the water in the water storage tank 31 is discharged to the drainage facility via the pipe S6. Is done.

  When a failure occurs in the water level sensor 34 or the on-off valve V2 of the water storage tank 31, the overflow water in the water storage tank 31 is piped from the drain port 36 located slightly above the set water level by the water level sensor 34. Through a drainage facility such as a public rainwater pipe (not shown).

  The adjustment tank 30 is supplied with water from the water storage tank 31 through the pipe S2 by the operation of the pump P1. This supply of water is continued until the water level W1 detected by the water level sensor 33 as the water level holding means reaches a set height. And the water level in the hollow part 14a is maintained by the detection of the water level sensor 33.

  That is, the water in the adjustment tank 30 is supplied to the hollow portion 14a via the water conduit 20 and the water distribution port 15 and accumulated therein, and is maintained at a predetermined water level W1. For this reason, the temperature of the panel 14 is lowered by contact with water, and the temperature is lowered by latent heat due to evaporation from the water surface.

  Here, the water level sensor 33 of the adjustment tank 30 includes a plurality of sensors 33A to 33C. And the function of one sensor 33A-33C is validated by switching means, such as a switch which is not illustrated. These sensors 33 </ b> A to 33 </ b> C have different vertical positions, and the set water level W <b> 1 differs depending on the difference in the vertical position. For example, the sensor 33A sets the water level W1 at the highest position of the depression 14a to increase the water depth in the depression 14a, and the sensor 33B sets the water level W1 at the upper and lower intermediate positions of the depression 14a. The water depth in the part 14a is made shallow, and the sensor 33C sets the water level W1 low to a height at which water is not stored in the recessed part 14a.

  In the case where the water in the hollow portion 14a is discharged from the water distribution port 15 or the rainwater in the hollow portion 14a is discharged, the water level in the adjustment tank 30 is lowered by opening the on-off valve V1.

  During this drainage, water with dust, sand, fallen leaves, etc. on the panel 14 flows in the direction of the base 25. At this time, large things such as fallen leaves are collected by the strainer 28 of the base 25, but dust smaller than the eyes of the strainer 28 reaches the inside of the water storage tank 31 through the pipe S1. Here, the material collected on the upper surface of the strainer 28 is easily removed by a normal cleaning operation. Water containing dust and the like that has passed through the strainer 28 is sent into the water storage tank 31, sent to the filtration device 32 by the operation of the pump P <b> 2, and after dust and sand are removed by the filtration device 32, the water is supplied to the water storage tank 31. Returned. Therefore, the water supplied to the adjustment tank 30 by the pump P1 is filtered water.

  In addition, when the water level sensor 33 (sensors 33A to 33C) in the adjustment tank 30 or the on-off valve V1 breaks down and the water level W1 rises above the position of the drain port 35, the overflow water in the adjustment tank 30 It can flow to a drainage facility such as a public rainwater pipe not shown through the pipe S3. Even when there is no failure, if the water level W1 rises due to rain or the like, a large amount of rainwater can be discharged. As a result, the water level W1 is maintained. Accordingly, the pipe S3 constitutes a water level holding means. In addition, drainage facilities, such as public rainwater pipes, are provided through drainage grooves in the appropriate positions such as the edge and intermediate position of the pavement 10, and through the drainage grooves, the rainwater during heavy rain passes through the tanks 30 and 31. It can also be flowed directly to.

Therefore, according to the above embodiment, the following effects can be obtained.
(1) In the above embodiment, since the water supplied from the water distribution port 15 to the recess 14a of the panel 14 is always stored as a sufficient amount of water, the panel 14 is effectively cooled by the water. That is, the panel 14 is cooled by removing heat from the latent heat of vaporization in the recess 14 a and heat exchange between the water in the recess 14 a and the water conduit 20. Therefore, the temperature in the vicinity of the panel 14 and its surface can be efficiently reduced. Moreover, the scenery which the water surface spread as the paving stone pavement 10 whole can be exhibited with the water stored by the hollow part 14a of the panel 14. FIG.

  (2) According to the said embodiment, the water level W1 of the hollow part 14a can be adjusted with the sensors 33A-33C. For example, on a summer holiday, the water level W1 is set at the highest level of the depression 14a to increase the water depth in the depression 14a to enhance the cool feeling. W1 is set so that a pedestrian can walk without worrying about a puddle, and water is not stored in the hollow portion 14a in winter. In this way, an appropriate water level can be obtained according to the season and situation.

  (3) In the above embodiment, the water conduit 20 for supplying water to the water distribution port 15 is formed on the back surface of the panel 14. For this reason, the water channel which consists of the water conduit 20 can be formed between the panel 14 and the roadbed 12 only by arrange | positioning the panel 14 on the roadbed 12. FIG. Therefore, it is not necessary to circulate piping for the water channel, and the paving stone pavement 10 having a cooling function can be easily constructed.

(4) In the said embodiment, since the panel 14 should just be shape | molded so that the hollow part 14a and the water conduit 20 may be formed, the manufacture is simple and suitable for mass production.
(5) In the above embodiment, since a sufficient amount of water can be stored in the recess 14a, it is not necessary to use a porous panel 14. For this reason, generation | occurrence | production of moss etc. can be suppressed and the surface of the paving stone pavement 10 can be maintained cleanly.

  (6) In the above embodiment, since the water conduit 20 is formed on the back surface of the pavement panel 14, the water channel is formed only by laying the pavement panel 14 on the roadbed 12. This simplifies the construction.

  (7) In the above embodiment, water supply and drainage can be performed between the conduit 20 and the adjustment tank 30 through the pipe S1. And the water level W1 on the paving stone pavement 10 can be adjusted to a predetermined height by the water level sensor 33 of the adjustment tank 30. For this reason, even if water evaporates, the water level W1 of the hollow part 14a can be maintained at a predetermined value, and it is possible to prevent the cooling from being hindered.

(8) In the above embodiment, the water distribution port 15 also serves as a drain port. Therefore, even if the depression 14a is formed, unnecessary water such as rainwater can be appropriately discharged.
(9) In the above embodiment, since the strainer 28 is provided on the base 25 of the water distribution port 15 on the panel 14, large dust or the like can be separated from the water flowing into the water distribution port 15 by the strainer 28. Further, when the strainer 28 is clogged, the strainer 28 can be easily cleaned by screwing the base 25 and removing it from the female screw body 41. Therefore, in the cleaning of the water distribution port 15, labor and cost such as using a high pressure washer are not required.

(10) In the above-described embodiment, it is not necessary to form the recess 14a deeply. Therefore, the inclination of the recess 14a becomes gentle, and the pavement 10 that is easy to walk can be realized.
(11) In the above embodiment, since the strainer 28 is provided at the upper end of the base 25, it is possible to prevent the heel of the high heel from being fitted into the base 25 and to realize the pavement 10 that is easy to walk.

  (12) In the above embodiment, the boss-like projections 17 a and ribs 17 b for restricting the opening width of the joint 16 are provided on the outer periphery of the sheath tube 17. In this way, since the pavement panel 14 can be arranged with reference to the protrusions 17a and the ribs 17b, the ease of construction of the pavement panel 14 is improved, and the pavement panel 14 can be laid accurately at a required position. Therefore, since the position of the panel 14 is regulated so that the opening width of the joint 16 is constant, the appearance of the paving stone pavement 10 can be improved.
