Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention naturally cools artificial grass laid on the ground, especially water-permeable artificial grass with cold air in the ground, and introduces rainwater accumulated on the grass surface into the ground. The present invention relates to a natural air-cooled dewatering device for water-permeable artificial turf, which is suitable for removing drainage.

[0002]

2. Description of the Related Art In recent years, there have been an increasing number of exercise facilities where artificial grass is laid outdoors or indoors. One of the major problems in laying artificial grass on the ground is removing water such as rainwater accumulated on the grass surface and raising the temperature of the artificial grass. In the case of water-permeable artificial turf, it is possible to allow water to penetrate through the grass, but a drainage mechanism that effectively introduces the water that has passed through the grass into the ground and drains it is required. When artificial turf is heated to a high temperature, the life of the turf itself is shortened and the human body using the artificial turf is also adversely affected. Therefore, a means for cooling the grass has been conventionally adopted, but none has been very effective. The naturally-cooled water removing apparatus for artificial turf shown in FIG. 13 is one of the conventional techniques created by the same applicant. The artificial turf 5a is laid on the inorganic soil member 30, and an air-cooling water collecting pipe 31 is erected in the ground below it, and the water-cooling water collecting pipe 31 extends radially from the center of the air-cooling water collecting pipe 31. 32 are connected. Further, the cap member 3 is provided below the air-cooled water collection pipe 31.
The water collection and drainage pipe 34 is connected via 3. Air-cooled water collection pipe 31
The upper portion of the above is closed by an upper lid 35, and a large number of water passage vents 36 are formed through the upper lid 35, and a separating member 37 which forms a taper at the end is connected downward. A water passage vent 38 is formed on the artificial turf 5a side of the collected / collected air collecting / discharging body 32, and a separating member 39 for guiding rainwater and the like contained in the collecting / cooling collecting / discharging body 32 to the air-cooled collecting pipe 31 side. Are inclined and arranged. A water passage 40 is formed through the separating member 39. The water collection and drainage pipe 34 is mainly composed of a compartment 41 through which rainwater and the like flow, an air passage 42, and the like, and is arranged so as to extend in the direction perpendicular to the paper surface of FIG.

In FIG. 13, rainwater and the like accumulated on the artificial turf 5a passes through the inorganic soil portion 30 and the air-cooling water collection pipe 31 and the water-passage vents 36 and 38 of the water-collecting cold / air collecting / discharging body 32, and the inside thereof. Enter into the air-cooled water collection pipe 31 by being guided by the separating members 37 and 40. In addition, the water passes through the water holes 40 of the separating member 39 and penetrates into the soil 43. Rainwater and the like that have entered the air-cooled water collection pipe 31 pass through the cap member 33, and the water collection and drainage pipe 34
Is sent from the compartment 41 to the drain side of the circuit and drained. On the other hand, since the temperature of the underground where the water collection and drainage pipe 34 is buried is low, the cold air in the compartment 41 and the air passage 42 of the water collection and drainage pipe 34 rises in the air cooling water collection pipe 31 and its upper lid 35 and water collection cold air collection. It is sent from the emitter 32 to the artificial turf 5a side to cool the artificial turf 5a. By the above, natural air cooling and water removal are performed.

[0004]

Although the natural cooling and water removing device for artificial turf shown in FIG. 13 performs natural air cooling and water removal of the artificial turf as described above, it has the following problems. Since the water collecting / collecting cool air collecting / discharging body 32 which spreads radially along the laying direction of the artificial grass 5a is arranged at the same level position as the upper lid 35 of the air cooling collecting pipe 31, a part of the cool air in the ground is cooled by the air cooling collecting pipe. Air is directly sent from 31 to the artificial turf 5a side, and the degree of cooling the entire artificial turf 5a through the water collecting / cooling / collecting body 32 is reduced. Further, a part of the rainwater from the artificial turf 5a is collected, and the water passage hole 40 of the separating member 39 of the cold air collecting and discharging body 32 is collected.
Directly penetrates into the soil from the
The amount of drainage is small, and most of it is sent to the outlet side via the air-cooled water collection pipe 31 and the water collection and drainage pipe 34. Therefore, it is difficult to quickly and sufficiently drain the water. Further, since the holding means for securely holding the radially collected water / cooling / collecting body 32 at a predetermined position in the soil 43 is not provided, the water collecting / cooling / collecting body 32 and the air-cooled water collecting cylinder 31 are not connected to each other during long-term use. Misalignment is likely to occur at the connection part of.

The present invention solves the above-mentioned problems, and allows rainwater on artificial grass to be reliably introduced into the ground for rapid water removal, and cool air in the ground to be evenly distributed on the artificial grass side. In addition, it is an object of the present invention to provide a natural air-cooled dewatering device for water-permeable artificial turf that can lead to a wide range and reliably cool the turf, and can be stably maintained in the ground for a long time.

[0006]

In order to achieve the above-mentioned object, the present invention is to collect and discharge wastewater which is vertically and horizontally buried in the ground where a water-permeable artificial turf is laid to form a drainage channel and an air passage. An empty pipe, an air-cooled water collecting cylinder which is erected on the pipe and forms water passages in the upper and lower sides, and an end portion of the air-cooled water collecting cylinder which is fixed on the Ascon layer between the cylinder and the water-permeable artificial turf. And a plurality of air-cooled water collecting radiators that are arranged at the center and extend radially from the center, wherein the air-cooled water collecting radiator forms a through groove in its longitudinal direction and A natural air-cooling dewatering device for a water-permeable artificial turf, which is formed by forming a plurality of vertical through holes communicating with a groove and having an equal pitch and / or an unequal pitch, and forming a downwardly sloping flange portion at the periphery thereof. It is a thing.

[0007]

[Operation] In the ground, collecting and draining air pipes are buried vertically and horizontally, and the air-cooled water collecting cylinders are erected and fixed on the pipes. Above the air-cooled water collecting cylinder, air-cooled water collecting radiators, which are fixed on the Ascon layer, are radially arranged, and artificial grass is laid on the air-cooled water collecting radiator. With the above structure, the air-cooled water collection and discharge body is stably held in the ground.
Rainwater collected on the artificial turf invades the air-cooled water collection and discharge body located directly below the artificial turf, flows along the vertical through holes and through grooves, and penetrates into the soil on the way. While being drained, the remaining rainwater is collected in an air-cooled water collection tube and descends. The rainwater that has descended is sent to the drainage port via a collection and drainage air pipe. On the other hand, the cool air in the ground enters the inside of the air-cooling water collecting pipe from the collecting and draining air pipe, rises in the pipe and is radially sent along the through groove, passes through the vertical through hole, and cools the lower surface of the artificial grass. Thereby, the entire surface of the artificial grass is cooled substantially uniformly.

Below the water-permeable artificial grass 5, an artificial grass underpad 6 is laid. As shown in FIG. 3, four air-cooled water collecting and directing bodies 1 are arranged below the artificial turf underpad 6 so as to be orthogonal to each other and extend radially. The front end portions of the four air-cooled water collecting and directing bodies 1 are gathered in one place, and the air-cooled water collecting cylinders 2 are erected upright below the gathering center position. It should be noted that the air-cooled water collection radiator 1
Is supported on the water permeable ascon layer 7, and the peripheral flange portion 18 (FIG. 8) is solidified by the asphalt-based caulking 44 to stably support the air-cooled water collecting and directing body 1 on the water permeable ascon layer 7. A crushed stone layer 8 is formed below the permeable ascon layer 7, and soil 12 is formed below the crushed stone layer 8. The air-cooled water collecting cylinder 2 is arranged so as to straddle the permeable ascon layer 7, the crushed stone layer 8, and the soil 12. A bottom joint 9 is fitted to the lower end of the air-cooled water collection tube 2. The bottom joint 9 is placed on the stabilizer 10 which is fixed in the soil 12 through the auxiliary support 11 and the like.
Below the bottom joint 9, the collection / drainage air supply pipe 3 is arranged.

4 and 5 show the detailed structure of the connecting component between the air-cooled water collecting and directing body 1 and the air-cooled water collecting cylinder 2. The tip end of each air-cooled water collecting and directing body 1 is formed at a right angle, and is arranged in close contact with the adjacent air-cooling and water collecting and directing body 1. A large number of water passage vents 14 are formed through the upper lid 13 of the air-cooling water collection tube 2 arranged at the end of the air-cooling water collection directing body 1. Further, a tapered separating member 15 having a narrow end is fixed below the upper lid 14 by opening the lower part.

FIGS. 6 to 8 show the detailed structure of the air-cooled water collecting and directing body 1. The air-cooled water collecting and directing body 1 is made of an elongated block-shaped member, and the tip portion thereof is formed at a right angle as described above. Two through-grooves 16 and 16 are formed so as to penetrate along the longitudinal direction with both ends open. A large number of the vertical through holes 17 are arranged along the longitudinal direction, are formed to penetrate along the thickness direction of the air-cooled water collecting and directing body 1, and communicate with the through grooves 16, 16. The vertical through hole 17 is formed by a taper hole that widens toward the end. As shown in FIGS. 3 to 6, the hole pitches between the adjacent vertical through holes 17, 17 are equal to the pitch P ₁ on the front side, and the pitch P ₂ is smaller on the extension end side than the pitch P _1. Arranged in order to achieve uniform ventilation. Further, as shown in FIG. 8, a downwardly inclined flange portion 18 is formed on the peripheral edge of the air-cooled water collecting and directing body 1.

FIG. 9 and FIG. 10 show the detailed structure of the collection / drainage air supply pipe 3. As well shown in FIG. 10, the horizontal cross-sectional shape of the water collection and drainage air pipe 3 is a drainage channel 22, 23 defined by a V-shaped member 19, a vertical member 20, and a semi-arc member 21.
An air passage 26 surrounded by the upper member 24, the vertical arc members 25 and 25, and the half arc members 21 and 21, and the half arc member 2
1, 21, vertical members 20, 20, and an air passage 28 surrounded by a bottom member 27. The collection / drainage air supply pipe 3 having the cross-sectional shape shown in FIG. 10 is elongated in the longitudinal direction as shown in FIG. Although not shown, the collection / drainage air pipe 3 is connected to the adjacent collection / drainage air pipe 3 via an intermediate joint.

FIG. 11 and FIG. 12 show a connecting structure of the bottom joint 9 fitted to the lower end of the air-cooled water collecting cylinder 2 and the water collecting and draining air pipe 3. The bottom joint 9 is formed by projecting the reduced diameter cylindrical portion 29 downward. The reduced diameter cylindrical portion 29 penetrates the upper portion of the water collection and drainage air supply pipe 3 and faces the air passage 28.

Next, the operation of this embodiment will be described mainly with reference to FIG. Rainwater collected on the water-permeable artificial grass 5 passes through the gap between the grass eyes and the underpad 6 for artificial grass, and penetrates into the vertical through-holes 17 of the air-cooled water collecting and dissipating body 1 which are firmly held by the water-permeable ascon layer 7. To do. As shown in FIG. 1, since the air-cooled water collecting radiators 1 are radially arranged in a large number of four air-cooling water collecting tubes 2, respectively, almost all of rainwater on the water-permeable artificial turf 5 in a wide range can be collected. It is introduced into the vertical through hole 17. Vertical through hole 17
Is formed from a taper hole that widens toward the end, so that the vertical through hole 17
The rainwater introduced therein enters the through groove 16 while diffusing into the through groove 16 and flows in the through groove 16. While flowing through the through-groove 16, rainwater permeates into the water-permeable ascon layer 7 which is in contact with the through-groove 16 and penetrates into the soil 12 through the crushed stone layer 8 and is drained. The remaining rainwater that does not enter the water permeable ascon layer 7 side passes through the water passage vent 14 of the upper lid 13 of the air-cooling water collection tube 2 communicating with the through groove 16 and is guided by the separating member 15 into the air-cooling water collection tube 2. Next, the rainwater passes through the through hole of the reduced-diameter cylindrical portion 29 of the bottom joint 9, enters the air passage 28 of the water collection and drainage air pipe 3, flows along the longitudinal direction thereof, and is discharged from the discharge port. Note that rainwater and the like in the soil 12 also enter the drainage channels 22 and 23 of the collection and drainage air-conveying pipe 3, and are sent to the drainage port side together with the air flowing in the air passages 26 and 28 to be drained. As described above, rainwater and the like accumulated on the water-permeable artificial grass 5 are completely discharged. On the other hand, when the amount of rainwater is relatively small, the inside of the collection / drainage air supply pipe 3 becomes empty, and cold air in the ground accumulates. This cold air flows into the bottom joint 9 from the air passage 28 having a relatively large area, rises in the air-cooled water collecting cylinder 2, and is introduced into the through hole 17 from the water passage 14 of the upper lid 13.
Cold air rises upward from the vertical through-grooves 16 while flowing along the through holes 17. In addition, the vertical through-groove 16 is an air-cooled water collecting and directing body 10.
Since the hole pitch P ₂ on the side of the extension direction is shorter than the hole pitch P ₁ on the side of the tip end, the cold air positively rises on the side of the extension end. Thereby, over the entire length of the air-cooled water collector directing body 1, the cool air travels upward substantially uniformly. The water permeable artificial turf 5 is naturally cooled from the lower surface by the cool air rising from the plurality of vertical through holes 17 of the air-cooled water collecting and directing body 1. On the other hand, as described above, since the flange portion 18 forming the inclined surface of the air-cooled water collection directing body 1 is firmly fixed to the water-permeable ascon layer 7 by the asphalt-based caulking 44, the air-cooled water flow directing body 1 can be used for a long time. Even with the use of, it is possible to exert air cooling and water removal functions without displacement.

In this embodiment, the air-cooled water collecting and directing body 1 having the vertical through-holes 17 and the through-grooves 16 communicating therewith is radially arranged above the air-cooling and water collecting cylinder 2 to have an originality. However, the detailed structure of each component is not limited to the contents of the above-described embodiment.
