  The operation of watering a road surface or a planting zone along the road with a watering vehicle is not only for ordinary roads, but especially for expressways, because the speed of watering cars and ordinary vehicles differ, so that safety can be ensured and smooth. There are many problems in securing the flow of cars, and it is happening that watering work cannot be performed quickly when needed.

  This invention is made | formed in view of said situation, Utilizing the technique which arrange | positions the water tank which can store rain water temporarily described in the said patent document 1 or the patent document 2 in the ground It is an object of the present invention to disclose a road watering system that can perform watering on roads, in particular, watering on expressways easily and reliably without using a watering vehicle.

  A water sprinkling system according to the present invention includes a side ditch installed along a road, a water storage device buried in the ground to store water flowing through the side ditch, and a discharge for discharging water stored in the water storage device. A watering facility comprising at least a pump and a long watering pipe disposed along a road to spray water discharged from the discharge pump to the ground surface.

  In the road watering system according to the present invention, rainwater flowing into a gutter installed along the road during a rain flows into a water storage device buried in the ground via a water collecting trough and the like, and is stored therein. The When water needs to be sprinkled, the rainwater stored in the water storage device is sent to a long sprinkling pipe by the operation of the discharge pump and sprinkled from there. As an example, the sprinkling pipe has a length of about 100 to 400 m and is arranged along the road. Therefore, in the region where the sprinkling pipe is arranged along the road, a watering wheel is not used. Rainwater stored on the road surface can be sprinkled.

  Means for introducing water from other water sources such as tap water can also be provided in the water tank. In this aspect, when the amount of rainwater is smaller than the required watering amount, water from other water sources can be used for watering, so the convenience as a road watering system is further improved.

  In any aspect, since most of the water sprayed on the road flows again into the road side ditch, the water once used for watering can be used again for watering. That is, water can be recycled.

  In a preferred aspect of the road watering system according to the present invention, two or more of the watering facilities are installed along the road. By adopting this mode, even a road with a long route length can be sprinkled on the road surface or the like without using a water truck.

  In the road watering system according to the present invention, preferably, the water storage device includes at least a sand basin into which water from a lateral groove flows and a water storage tank that stores the water that has flowed into the sand basin. And the screen which can remove a solid substance and a suspended | floating matter is arrange | positioned in the water inflow part from the said sand basin to the said water storage tank.

  In the road watering system of this aspect, by providing a sand basin, it is possible to prevent dirt and the like from entering the water tank, and the maintenance of the water tank becomes easy. Furthermore, by providing a screen, it is possible to prevent light solids or suspended matters in water from entering the water storage tank. In other words, since the water storage tank stores purified water that does not contain fixed or floating substances, it does not contaminate the road surface when water is sprayed on the road. In addition, when recycling water as described above, earth and sand etc. that have been included once by cleaning the road surface are removed by a sand basin or screen, so when the water is stored again in the water tank, As it becomes stored.

  In the above aspect, the screen may be a flat metal mesh having a stitch of a predetermined size. However, in the case of a flat screen, clogging over a large area is likely to occur because a resin sheet or the like mixed in rainwater adheres to the screen surface. In order to solve this problem, it is desirable to use a screen having one or a plurality of cylindrical bodies extending in the transverse direction in the sand pit as the screen. In this aspect, the effective area as a screen can be increased compared to a screen that is simply a flat plate, the screen effect is improved, and it is possible to avoid the difficulty of water flowing into the water tank due to clogging. There is also an effect.

  In one aspect of the screen, a porous material is sealed inside the cylindrical body as a filter medium. Examples of porous materials include resin foams containing porous urethane, carbon such as activated carbon, charcoal and bamboo charcoal, minerals such as zeolite, porous ceramics, nonwoven fabrics, synthetic organic polymer materials, and natural organic polymers. Materials etc. can be mentioned. By filling the porous material to such an extent that the flow of rainwater is not hindered, it becomes possible to store the purified water purified to a higher degree in the water storage tank. In addition, by replacing the porous material, it is possible to use the screen while maintaining high filtration performance over a long period of time. In addition, a synthetic organic polymer material or a natural organic polymer material can be used as long as it can function as a filter medium. By enclosing such a porous material in a cylindrical body, it becomes possible to more reliably remove substances such as organic substances, suspended substances, fine particles, suspended substances, and odor components in water.

  In one embodiment of the screen, the water can be purified by biological treatment. Examples of microorganisms used for biological treatment include bacteria, fungi, protozoa, and minute metazoans. Even in this case, the purified water that has been purified to a higher degree can be stored in the water storage tank.

  In one aspect of the road watering system according to the present invention, a power generation unit including a solar panel may be further provided, and the discharge pump may be driven by the power generated by the power generation unit. In this aspect, natural energy can be effectively used, and a road watering system with a smaller environmental load can be obtained. In addition, when the above-described solar panel is provided in the road watering system in which the above-described purified water is stored in the water storage tank, the surface of the solar panel can be cleaned using the water stored in the water storage tank. The high power generation performance of solar panels will be maintained.

  In the road watering system according to the present invention, the above-described long watering pipes may be arranged not at the road surface but at a position where water can be sprayed with respect to the planting belt installed along the road. In this embodiment, rainwater or the like can be used for planting the planting zone, and the environment becomes more environmentally friendly.

  The road watering system according to the present invention can exhibit particularly high effectiveness by being installed along an automobile exclusive road or an expressway, but it is naturally effective even when installed along a general road. Demonstrate.

And the water which flowed into the water collecting basin 10 flows into the “watering equipment” A according to the present invention through the water conduit 11 buried in the ground.

  In this example, the watering facility A includes a sand basin 20, a water tank 30, an outflow basin 40, a discharge pump 50, and a long watering pipe 60. The sedimentation basin 20, the water tank 30, and the outflow basin 40 are buried under the road, and the sedimentation basin 20 and the outflow basin 40 have openings 21 and 41 as management ports on the road surface.

  The sand basin 20 is made of concrete and has a connection opening 22 with the water conduit 11 on one wall, and two openings 23 and 24 (see FIG. 3) at a distance in the vertical direction on the other wall. Have. The upper opening 23 is at a position slightly below the connection opening 22, and the lower opening 24 is at a position higher than the bottom 25 of the sand basin 20. Each opening 23, 24 is usually fitted with a mesh screen.

  The water storage tank 30 is not limited, but in this example, as described in Patent Document 2 described above, a row of convex portions is a resin molded product formed in parallel with a plurality of rows at a constant interval. It is a water storage tank formed by laminating a plurality of water storage space forming members 31 alternately at right angles, and is entirely covered with a water-impermeable sheet 32. A concrete plate 33 as a base material is installed under the water tank 30, and a concrete plate 34 as a load distribution plate is installed on the upper surface.

  The bottom surface of the water storage tank 30 is located slightly below the lower opening 24 formed in the sand basin 20, and the upper surface is located slightly above the upper opening 23 formed in the sand basin 20. One end face side of the water storage tank 30 is in contact with a side wall in which the two openings 23 and 24 of the sand basin 20 are formed, and the internal space of the sand basin 20 and the water tank 30 are connected through the two openings. Communication with the water storage space.

  The outflow rod 40 is made of concrete, and one side wall thereof is in contact with the other end face side of the water storage tank 30. And two openings 41 and 42 are formed in the side wall in contact with the water storage tank 30 and facing the upper part and the lower part of the water storage tank 30. Although not shown, the openings 41 and 42 are each provided with an appropriate orifice, more preferably a movable orifice, that can regulate the outflow of water stored in the water storage tank 30. And the above-mentioned discharge pump 50 is installed in the bottom part of the outflow soot 40 in the aspect waterproofed.

  As shown in FIG. 1, a rising pipe 61 to the ground surface is connected to the discharge side of the discharge pump 50, and the rising pipe 61 passes the planting zone 2 installed at the center of the above-described roadway 1 in the route direction. Connected to the running sprinkler pipe 60.

  Although not shown, a storage battery facility for storing power generated by the solar panel 6 is provided at the stop 5 or in the vicinity thereof, and the discharge pump 50 is activated by power from the storage battery in addition to commercial power. Yes.

  FIG. 4 is a perspective view schematically showing another example of a road surface provided with the road watering system according to the present invention. In this aspect, the planting zone 2 is not installed at the center of the roadway 1, and Only the watering pipe 60 described above is buried in the vicinity of the center, and its discharge hole 62 appears on the road surface. Other configurations are the same as those shown in FIGS. 1 and 2, and are denoted by the same reference numerals in the drawings.

  The operation mode of the road watering system will be described. When it rains, the rainwater around the road 1 and its surroundings flows into the road side groove 4. The rainwater that has flowed in is collected in the catchment basin 10 and then flows into the sand basin 20 through the water conduit 11. The earth and sand contained in the inflowing rainwater is settled and removed at the bottom of the sand basin 20. When the inflow amount of rainwater increases and the water surface level becomes higher than the level of the lower opening 24, the rainwater enters the water storage tank 30 and is stored therein. The rainwater stored in the water storage tank 30 flows out to the outflow tank 40 by an amount regulated by the orifice provided in the opening 42 of the outflow tank 40, and the remaining amount is stored in the water storage tank 30 as it is.

  In addition, if the air in the water storage tank 30 does not escape, it becomes difficult for rainwater to flow into the water storage tank 30, so that the upper openings 23 and 41 act as vents for extracting the air in the water storage tank 30. When the amount of rainwater flowing into the sand basin 20 further increases, rainwater enters the water storage tank 30 from the upper opening 23 and is stored there. In addition, when the water storage tank 30 becomes full, water can be discharged from the upper opening 41 to the outflow trough 40 before the concrete plate 34 on the upper surface is filled with buoyancy.

  When the water spray from the water spray pipe 60 becomes necessary, the discharge pump 50 is operated. Thereby, the rainwater stored in the outflow rod 40 is pumped to the sprinkling pipe 60 via the riser pipe 61, and water is sprayed from the discharge hole to the plants in the planting zone 2 in the embodiment shown in FIGS. Is done. Moreover, in the aspect shown in FIG. 4, it sprinkles on a road surface from the discharge hole opened on the ground surface of the water sprinkling pipe 60 embed | buried on the road surface. When pumping by the discharge pump 50 starts, negative pressure is generated in the orifice portion provided in the opening 42 of the outflow basin 40, so that rainwater stored in the water storage tank 30 is drawn out to the outflow basin 40 side and sprinkled. . When the movable orifice is used, more water can be continuously sprinkled by increasing the opening of the orifice at the same time as the pumping by the discharge pump 50 starts.

  In a mode in which water is sprayed directly on the road surface, the sprinkled water flows again into the road side groove 4 except for the portion that evaporates while cleaning the road surface and taking the temperature of the road surface. And it flows into the sand sink 20 again and is used for water storage or watering.

  By installing a plurality of such watering facilities along the road, it is possible to water the plants in the planting zone 2 and clean the road surface using rainwater without running the watering wheel. It is possible to avoid the occurrence of traffic obstacles on highways and the like due to the traveling of different watering vehicles and ordinary vehicles.

  When the amount of rainwater is small, it may happen that a sufficient amount of water cannot be stored in the water storage tank 30. In order to avoid this, it is preferable that tap water or river water can be introduced into the sand basin 20 or the water storage tank 30.

  Depending on the road environment in which the road watering system is installed, the rainwater flowing into the road side groove 4 may contain a large amount of foreign matter such as a thin resin sheet and extremely small floating matters. In such a situation, the sheet sticks to the flat screen attached to the openings 23 and 24 of the sand pit 20 and the flow area is extremely reduced. In addition, extremely small suspended matter may pass through the screen and enter the water storage tank 30. In either case, the water storage capacity of the water storage tank 30 is adversely affected, which is not preferable.

  FIG. 5 shows an example of a screen 70 having a cylindrical body that can effectively avoid such a situation. Moreover, the example which attached the screen 70 of the form to the openings 23 and 24 of the sandbox 20 is shown by FIG. 1, FIG.

  A screen 70 </ b> A shown in FIG. 5A includes a vertical surface member 71 and a cylindrical body 72, which is a single or a plurality of (four in the illustrated example) cylindrical bodies standing on the surface material 71. Consists of. The vertical face material 71 may be any size as long as it can block the openings 23 and 24 of the sand pit 20 and is shown as a rectangle in the figure. However, the vertical face material 71 may have an appropriate shape according to the shape of the opening to be attached. That's fine. Further, the face material 71 may be perforated as shown, or may be non-porous. It is essential that the cylindrical body 72 is made of a porous material such as a metal mesh. When the face material 71 is a perforated material, the hole diameter is preferably smaller than the hole diameter of the cylindrical body 72.

  The length of the cylindrical body 72 is set in accordance with the shape and size of the horizontal cross section of the place where the screen 70A is attached (in the illustrated example, the sand basin 20). Although the length which can cross a horizontal cross section may be sufficient, since the attachment with difficulty and resistance with respect to the flow of water become large too much, it is preferable that it is the length to the middle. The thickness and the number of the cylindrical bodies 72 are also set to appropriate numbers in consideration of the resistance to water flow and the required degree of purification. Moreover, it is preferable that the cylindrical body 72 is attached so that it can be attached or detached with respect to the face material 71, and is further supported by the angle material 74 attached to the face material 71 side, as shown in FIG.5 (b). It is preferable.

  As shown in FIG. 1 or FIG. 3, when the screen 70A is attached to the openings 23 and 24 of the sand basin 20, a thin resin sheet or the like is included in the rainwater, and when it sticks to the screen 70A, The ratio of the area where the screen is clogged by the stuck resin sheet or the like to the total area of the screen is smaller than the case where the screen is simply a flat body, because it has a cylindrical body 72, As a result, it is possible to greatly reduce the probability of clogging that would hinder the screen 70A.

  The inside of the cylindrical body 72 may be empty. When it is desired to further increase the purification degree of rainwater stored in the water storage tank 30, an appropriate porous material can be filled into the cylindrical body 72. The filled porous material functions as a filter medium, can remove fine foreign matters and suspended matters in rainwater, and the degree of purification of stored water is increased. Porous materials include resin foams containing porous urethane, carbon such as activated carbon, charcoal and bamboo charcoal, minerals such as zeolite, porous ceramics, nonwoven fabrics, synthetic organic polymer materials, natural organic polymer materials, etc. It can be illustrated.

  In addition, as described above, in one embodiment of the screen, water can be purified by biological treatment. Examples of microorganisms used for biological treatment include bacteria, fungi, protozoa, and minute metazoans. Even in this case, the purified water that has been purified to a higher degree can be stored in the water storage tank.

  By storing rainwater having a high degree of purification in the water tank 30 in this way, the water pumped up by the discharge pump 50 is used as washing water for the solar panel 6 attached to the roof surface of the stop 5 described above. This makes it possible to further improve the efficiency of the entire road watering system.

  The screen 70B shown in FIG. 5C has a rectangular cross section of the cylindrical body 72, and is attached to the face material 71 in a posture in which one top side 73 thereof is the uppermost position. This is different from the screen 70A shown in FIG. When the screen 70B of this form is attached to the openings 23 and 24 of the sand basin 20, when the water level in the sand basin 20 decreases, foreign matter (solid matter) accumulated on the upper surface side of the cylindrical body 72 due to the flow of water. Material) can be easily poured out, and clogging of the cylindrical body 72 portion due to foreign matter (solid matter) can be eliminated without removing it by hand. Similar effects can be expected to some extent also in the cylindrical body 72 having a circular cross section shown in FIG.

  FIG. 6 shows another example of the watering equipment used in the road watering system according to the present invention. Here, an appropriate screen is also attached to the outlet side opening 12 of the water collecting basin 10 attached to the road side groove 4. In the illustrated example, the screen 70 shown in FIG. 5 is attached, but the present invention is not limited to this. By attaching an appropriate screen to the outlet side opening 12 of the catchment basin 10, the purification degree of rainwater flowing into the water storage tank 30 can be further increased. In this case, it is desirable to make the hole diameter of the screen attached to the water collecting basin 10 larger than the hole diameter of the screen attached to the sand settling basin 20 regardless of the form of the screen attached. Thereby, a large thing can be excluded in order and the removal efficiency in each screen improves.
