Description

  The present invention relates to a waterscape plaza system capable of obtaining a cooling action by a mist of water or producing a visual effect. Here, a plaza is a pavement that forms a sidewalk in addition to an outdoor plaza, a plaza inside a building, a room, a passage, or the rooftop of a building, such as a human walking space, a living space, and the surrounding space. Point to.

  In recent years, a waterscape plaza such as a plaza in which tap water is ejected in the form of a fountain from the road surface upward is being popularized in parks, station squares, and the like.

  The water eruption plaza mentioned above is that water erupts from the nozzles provided in the gaps between paving stones on the road surface, so that children can play with water mainly at high temperatures such as in summer. Is the purpose. In addition, a plaza using water-permeable pavement is also proposed. In this water-permeable pavement, rainwater, etc. is held in water-retaining pavement materials such as paving stones, or water is supplied to the water-permeable pavement materials using capillary action to remove heat of vaporization from the road surface and its surroundings. It aims to decrease.

  However, in the plaza system where water is ejected, a large amount of water is required, which not only increases the operation cost, but also cannot enter the ejection area other than children who do not hesitate to soak.

  Further, the water-permeable pavement tends to be unclean because dust or the like adheres to the surface of the pavement because the surface of the pavement is maintained in a wet state for a long time. In addition, plants such as moss tend to grow on the surface, and dirt may be noticeable. Moreover, although it is a system that utilizes evaporation of moisture, it cannot visually recognize the presence of water, and therefore cannot obtain a visual cool feeling, and cooling depends on evaporation of moisture only from the road surface. Therefore, the cooling effect is not sufficient. Rather, there is a risk of sultry heat being doubled at high temperatures and no wind and high humidity.

  On the other hand, Patent Document 1 discloses a spray facility in which water mist is discharged from a hollow body or the like standing between a sidewalk and a roadway toward the sidewalk. However, the configuration of Patent Document 1 is not configured so that the hollow body can be easily removed or rearranged when mist discharge is no longer necessary. Therefore, not only can the design layout of the spraying equipment not be easily changed, but also in the winter season when mist emission is unnecessary, the hollow body or the like becomes an obstacle.

  In addition, in a conventional waterscape plaza such as a station square, since the position of the water supply coupler for the waterscape facility is fixed, it is difficult to change the design layout of the facility as described above. Furthermore, when it is desired to use a mist generating device that generates a mist having a small particle size (dry mist) as equipment for obtaining a cool feeling, high-pressure water is required, and therefore normal low-pressure water cannot be used. Therefore, the mist generating device cannot be installed on the waterscape plaza as it is, so that it is necessary to install a portable mist generator on the waterscape plaza, which is extremely inconvenient.

On the other hand, a configuration as disclosed in Patent Document 2 has been proposed as a piping system. In the conventional configuration of Patent Document 2, a water distribution base pipe is laid in an urban area, and the drain base pipe is connected to a water source such as the sea, a river, or a lake through a pump. A plurality of branch pipes for connecting fire extinguishing equipment are connected to the distribution pipe.
JP-A-6-170294 Japanese Patent Laid-Open No. 10-33212

  However, in the piping system of Patent Document 2, a piping configuration for supplying water for fire extinguishing from a water source to an urban area is shown, but a configuration for supplying high-pressure water for spraying is not shown. Therefore, it is difficult to apply the piping configuration described in Patent Document 2 to a waterscape plaza system having spray equipment.

  The present invention has been made paying attention to such problems existing in the prior art. The purpose of this is a waterscape plaza system that can release water mist at the required locations of the waterscape plaza and not only can obtain an effective cool feeling by the water mist, but also can easily change the layout of the equipment. Is to provide.

  In order to achieve the above object, according to the present invention, a water pipe provided with a pressure capable of generating mist is provided below the lower surface of the space, and a connection terminal that can be connected to the mist generator is provided in the pipe. It is characterized by that.

  Therefore, in the waterscape plaza system of the present invention, spray equipment can be arbitrarily installed as necessary, and the equipment can be connected to a connection terminal of piping. Therefore, water mist can be discharged at a required location of the waterscape plaza, and an effective cool feeling can be obtained by the water mist. Moreover, when a spraying installation is unnecessary, the installation can be easily removed by canceling the connection. Therefore, if necessary, for example, when the event opens or closes, it is possible to easily remove the spray equipment installed. Here, the lower surface of the space is a pavement surface such as a plaza, a pavement road surface, an indoor space, an indoor floor surface, etc., where there are pedestrians and residents, and planting adjacent to the space. It refers to the lower surface of the space.

  In the above configuration, the connection terminal may be disposed in a recess formed in the lower surface of the space, and the upper surface opening of the recess may be provided with a grating so as to be openable. When comprised in this way, the connection terminal of fluid piping can be arrange | positioned, without exposing on the ground surface.

  Furthermore, in the said structure, while providing an electrical wiring along the said piping under the said space lower surface, it is good to provide the connector which can be connected with an electrical installation in the said electrical wiring in the said recess. When configured in this way, electrical equipment can be easily installed in the waterscape plaza.

  As described above, according to the present invention, water mist can be discharged at a required location of the waterscape plaza, and not only can the water mist provide an effective cool feeling, but also the layout of the equipment can be easily changed. The effect that it can be performed is demonstrated.

(First embodiment)
Below, 1st Embodiment which actualized this invention as a waterscape open space of a park is described based on drawing of FIGS.

  As shown in FIGS. 1 and 2, a plurality of fluid pipes 22, 23, and 24 for supplying different types of fluids are disposed below the pavement surface 21 as the lower surface of the space in the waterscape plaza. . These fluid pipes 22 to 24 are adjacent to each other and extend in the same direction, and are arranged vertically and horizontally as shown in FIG.

  As shown in FIGS. 1 and 2, among the fluid pipes 22 to 24, the first fluid pipe 22 is compressed air of at least twice, preferably four times or more of atmospheric pressure from a compressor 25 or a high-pressure chamber (not shown). Is supplied. High pressure water of 2 Mpa (megapascal) or more is supplied to the second fluid pipe 23 through a main plug 27 from a high pressure tank (not shown). The third fluid pipe 24 is supplied with low-pressure water having a pressure lower than that of the high-pressure water (about 0.2 Mpa) from a low-pressure tank (not shown) via a main plug 28. Drain passages 29 and 30 having drain valves 29a and 30a are connected to the base ends of the second fluid pipe 23 and the third fluid pipe 24, respectively.

  As shown in FIG. 4, recesses 31 are formed at a number of locations on the pavement surface 21 corresponding to the fluid pipings 22 to 24. These recesses 31 are distributed in a grid pattern. In addition, the planting belt | band | zone etc. around a waterscape open space may also be regarded as a part of the square, and the recess 31 may be formed in a planting belt. A grating 32 for closing the upper surface opening is removably attached to each recess 31. In addition, each said recess 31 is connected to the drainage facility (not shown) so that water may not accumulate in the inside. In each recess 31, couplers 33, 34, and 35 are provided in the fluid pipes 22 to 24 as connection terminals for connecting to various facilities described later. Each coupler 33, 34, 35 is provided with an on-off valve 33a, 34a, 35a that is manually opened and closed. Therefore, in each recess 31, the couplers 33, 34, and 35 are unitized to form a connection station.

  As shown in FIG. 3, a mist generating device 41 is installed in each of the recesses 31. The mist generating device 41 includes a mist nozzle 43 that is connected to the coupler 34 of the second fluid pipe 23 and points upward. Then, the high-pressure water in the second fluid pipe 23 is supplied to the mist generator 41. Due to the supply of the high-pressure water, a mist having a small particle diameter is ejected from the nozzle 43 of the mist generator 41 through the opening of the grating 32 toward the pavement surface 21 side. For this reason, the mist drifts slightly above the pavement surface 21 and can produce a visual cooling sensation, and is provided for actual cooling by vaporization of the mist. When the mist particle size is small, pedestrian shoes and clothing hems on the pavement surface 21 do not get wet unless the mist jet is applied for a long time.

  In this case, the particle size of the mist ejected from the nozzle 43 is arbitrarily set within a range of 15 to 500 μm by selecting the type of the mist generating device 41 (having a different diameter of the nozzle 43 nozzle). can do. If the nozzle 43 is selected to inject mist having a large particle diameter, or if the mist injection direction is selected to be parallel or downward to the road surface, the road surface can be wetted with mist, Is possible. It is also possible to select the mist generating device 41 that can set the range of the mist M ejected from the nozzle 43 to the circular state shown in FIG. 6 (a) or the rectangular state shown in FIG. 6 (b). Furthermore, by adjusting the pressure of the mist M injected from the nozzle 43, the injection distance of the mist M from the nozzle 43 can be adjusted stepwise as shown in FIGS.

  FIG. 5 shows an example in which a mist generating device 41 having another configuration is installed in the recess 31. The mist generating device 41 is configured such that the nozzles 43 on the support column 42 are directed in opposite directions. When the mist generating device 41 has a height that does not fit in the recess 31, the grating 32 is formed so as to swell upward as shown in FIG.

Further, as shown by a two-dot chain line in FIG. 5, a long column 42 may be used as the mist generating device 41, and the column 42 may be positioned above the opening of the grating 32.
FIG. 7 shows a mist generating device 52 configured such that a plurality of nozzles 53 are directed in all directions other than downward. Such a mist generator 52 may be used.

  FIG. 8 shows a bench 47 installed on the pavement surface 21 so as to correspond to an arbitrary recess 31. A mist generating device 48 is provided below the bench 47. The mist generating device 48 includes a plurality of spray nozzles 50 connected to the coupler 33 of the second fluid pipe 23 via a connecting pipe 51. For this reason, the high-pressure water in the second fluid pipe 23 is blown out around the bench 47 as a mist so that a visual cool feeling can be produced and used for actual cooling.

  FIG. 9 shows a mist generating device 60 suitable when the recess 31 is arranged in the vicinity of the tree t of the soil part 63. A tube 61 connected to the coupler 34 of the second fluid pipe 23 is wound around the branch of the tree t. The tube 61 is provided with a spray nozzle 62 at a predetermined interval. Accordingly, mist drifts around the tree t, and a visual cooling feeling can be produced, and it is used for actual cooling. At the same time, it is possible to irrigate the tree t with mist.

  For example, if a normal water supply hose is connected to the coupler 35 of the third fluid pipe 24 of the low-pressure water, normal water discharge is possible. If a faucet for fountain is connected to the coupler 35, fountain from the grating 32 is possible. It becomes. Therefore, in these cases, not only watering, irrigation of trees, washing of the pavement surface 21 and the like are possible, but also water play is possible.

  Further, if the mist generating devices 41, 48, 60 are connected to the third pipe of low-pressure water and the first fluid pipe 22 of compressed air, a mist having a small particle diameter called a two-fluid mist or a dry mist is ejected. It becomes possible.

Therefore, this embodiment has the following effects.
(1) A plurality of fluid pipes 22 to 24 for supplying compressed air, high-pressure water and low-pressure water are disposed under a pavement surface 21 such as a waterscape plaza, and various facilities are provided in the fluid pipes 22 to 24. The couplers 33 to 35 for connecting to are unitized in the recesses 31 dispersedly arranged at a number of locations and provided as connection stations. Therefore, it is possible to install and use a mist generating device that gives a cool feeling at a desired location of the waterscape plaza without being limited by the installation location and the number of installation. And the connection of the fluid piping 22-24 with respect to those facilities can be performed without the unpleasantness which extends a water supply hose etc., and the scenery improvement of a waterscape open space can be achieved.

  (2) When the mist discharge is no longer necessary, the connection by the couplers 33 to 35 may be released and the valves 33a to 35a may be closed. For this reason, according to a change of a season, holding of an event, etc., it is possible to easily remove the equipment of the mist generating device 41 or rearrange it.

  (3) By appropriately selecting the couplers 33 to 35 to be connected, it is possible to freely select discharge of one fluid mist having a relatively large particle size and two fluid mist having a small particle size, normal water discharge or air blowing, etc. Various applications can be realized. That is, in addition to the above-described mist discharge, for example, high-pressure water is used to wash the pavement surface 21 or the like, low-pressure water is used to irrigate trees or plants, and compressed air is used for blowing air. For example, it is possible to clean up by blowing away fallen leaves and garbage.

  (4) The couplers 33 to 35 of the fluid pipes 22 to 24 are arranged in a recess 31 formed in the pavement surface 21, and a grating 32 for opening and closing the upper surface opening is attached to the recess 31 so as to be openable. ing. For this reason, the couplers 33 to 35 of the fluid pipes 22 to 24 can be arranged without being exposed on the ground surface, in other words, without being disturbed.

  (5) Since the periphery can be cooled by mist, the amount of water used can be reduced and the operating cost can be reduced compared to the case where water is ejected. In addition, the mist can visually recognize the presence of water and give a visual cool feeling, as well as a sufficient cooling effect compared to the case of relying on vaporization only from the road surface of the water-permeable pavement. be able to. Moreover, since the mist is used, it is possible to prevent the pedestrian's shoes and clothes from getting wet, so that the user can walk comfortably on the waterscape plaza.

  (6) The mist hardly wets the pavement surface, and even if it becomes wet, the pavement surface dries immediately upon completion of spraying. For this reason, it can suppress that dust etc. adhere to the pavement surface, and can maintain a clean state.
