Abstract

PURPOSE:To reduce the equipment cost by vertically burying flat pipes in both longitudinal and lateral directions in the superficial layer of a road face to collect and filter the superficial water bearing agricultural chemicals and conducting the underground cold air to the substrate of road through the tubular materials to cool the road face. CONSTITUTION:The water bearing agricultural chemicals flows along the arc face of the cap 6 of a flat drain pipe 1 and penetrates into the inside from opened slits 8. The solid in water is removed by a filter 5 and the filtrate flows down in the paths 4 along the longitudinal direction of the pipe 1. And then the water flows to water-collecting/discharging pipes 33, 34 through a hollow pipe 21 to diffuse into the underground 32 and to decompose and neutralize the agricultural chemicals by the action of natural filtration and bacteria in the ground. When the surface of lawn gets warm, the cold air having permeated in the pipes 33, 34 rises in the pipe 1 through the pipe 21 and enters into spaces 19 and also exhausts from holes 8 to cool the road surface. In this way, the superficial water is effectively collected and neutralized. And further, the ground surface is always kept cold, the construction is simple and hence, the equipment cost can be reduced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat drainage pipe for draining and cooling a road surface such as lawn planted and having an air suction function effective for removing pesticides.

[0002]

BACKGROUND OF THE INVENTION Golf course tee ground, green,
Agricultural chemicals are sprayed on the road surface such as fairways where grass is planted for the purpose of growing grass and killing insects. On the other hand, in summer etc.
It is desirable that the road surface be cooled in order to prevent overheating. On the other hand, recently, the spraying of pesticides has become a serious pollution problem, and the amount and quality of pesticides to be sprayed has been limited.
Further, cooling the road surface requires a cooling equipment suitable for it, and the equipment cost is high, so that it is not implemented so often.

[0003]

To prevent runoff of water containing pesticides, the surface water of a golf course can be efficiently collected and decomposed by aeration in an aeration tank, rendered harmless, and then discharged. Also, to cool the road surface by simple means,
You can use the cold air in the ground.

The present invention was devised in view of the above circumstances, and it is possible to efficiently collect the surface water of the road surface on which lawns and the like are planted and guide it to the aeration tank, and cool underground cold air to the ground surface. An object of the present invention is to provide a flat drainage pipe body having an air suction function that can be guided to the side.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is arranged in the vicinity of a road surface to be planted, such as lawn, and makes a cross section forming an elongated passage substantially vertical. A flat drain pipe that is embedded in a pipe, has an opening at both the upper end and both ends in the longitudinal direction, forms an open hole communicating with the passage, and has a filter member such as a nonwoven fabric A flat type drainage pipe, which is configured to be housed in a passage, and has a cap member having an arc-shaped cross section covering the pipe body at the top of the pipe body with an appropriate gap from the opening at the upper end. It has an air sucking function by forming a body and attaching a connection socket for connecting the flat drain pipes to each other and other deformed pipes buried in the ground It constitutes a flat drainage pipe.

[0006]

The flat drainage pipe body of the present invention is flat and therefore can be arranged vertically and horizontally on the road surface, so that surface water on the road surface can be efficiently collected. Most of the pesticides are contained in the surface water, and if the surface water is collected efficiently, it can be easily decomposed and rendered harmless by aeration from the aeration tank. Since the tubular body of the present invention is flat and used by being buried in an upright state, the area for collecting and ventilating the water has a very small area and is unlikely to be damaged even when subjected to earth pressure. Since it can be arranged on the very surface layer of the road surface and can be arranged vertically and horizontally with a small area, surface water can be collected very efficiently. The pesticide sprayed on the road surface such as lawn is mixed with rainwater and introduced into the ground, guided by the cap member having an arc-shaped cross section, and enters the passage in the pipe through the open hole of the flat drain pipe. Since the filter member made of non-woven fabric or the like is housed in the passage, dust, dirt and the like are removed by filtration. The water from which dust and the like have been removed flows through the passage, is collected in an aeration tank and is aerated, and the pesticide is decomposed and rendered harmless. On the other hand, cold air accumulated in other pipes buried in the ground is guided under the road surface such as lawn by a flat drain pipe connected to the other pipe through a connection socket etc. Natural cooling is performed.

FIG. 10 shows a flat drain pipe 1 having the above structure.
It shows a state in which is arranged below the road surface where the lawn 31 is planted. Water collecting and draining pipes 33 and 34 are buried between the underground 32 in a shape like a deep well. The two are connected by a hollow pipe 21. The flat drain pipe 1 is connected to the hollow pipe 21 via a connection socket 22. The flat drainage pipe 1 is arranged upright in the ground, and the cap member 6 thereof is arranged close to the lower surface of the lawn 31. In order to render the pesticide harmless, it should be led to an aeration tank (not shown).
In this case, the collecting / draining vapors 33 and 34 and the aeration tank may be used together, or only the aeration tank may be directly or indirectly connected to the flat drain pipe of the present invention.

11 to 14 explain the outline of the burying work of the flat drainage member 1 among the components of this embodiment. As shown in FIG. 11, the drainage pipes 33, 3
4 and the place where the hollow pipe connected to it is buried,
A large pit 35 corresponding to these is required. On the other hand, since the flat drain pipe 1 is formed flat as described above, the relatively narrow groove 36 may be excavated. That is, as shown in FIG. 12, the groove 36 having the groove width a may be excavated along the longitudinal direction in which the flat drainage pipe 1 is embedded so as to communicate with the excavation hole 35. The groove 36 having the thin width a can be easily excavated by a groove width cutting device (not shown).

As shown in FIG. 13, in order to bury the flat drainage pipe 1, first, the groove 36 is excavated, and then elongated struts 37 are driven into both sides of the groove 36 at appropriate intervals to flatten the drainage. It is used as a guide for inserting the tubular body 1. Next, as shown in FIG. 14, the flat drainage pipe body 1 is inserted between the columns 37, 37,
Store in the groove 36. After storing, the residual soil 38 is put into the groove 36. As described above, when the flat drainage pipe body 1 is buried, the amount of soil to be excavated is extremely small, and the treatment of the remaining soil is simplified.

Next, the operation of this embodiment will be described. The flat type drain pipe 1 shown in FIG. 1 forms an elongated passage 4 and is reinforced by a rib member 3 so as not to be concave due to the earth pressure. Pesticides are sprayed on the lawn 31, and the pesticide enters the ground 32 from the lawn 31 along with rainwater and the like. The water containing the pesticide is guided in the longitudinal direction along the cap member 6 of the flat drainage pipe 1, and the pipe main body 2 along the arc surface of the arcuate portion 16.
Through the slit-shaped open hole 8 of.

Since the filter member 5 made of a non-woven fabric or the like is located near the open hole 8 of the tube body 2, the water from which dust and dirt are removed by filtration advances downward in the passage 4 and is flattened. It flows along the longitudinal direction of the drainage pipe 1. Since the hollow pipes 21 are connected to both ends in the longitudinal direction via the connection sockets 22 and the like, water enters the hollow pipes 21 and is sent to the side of the collecting and draining pipes 33, 34 which are connected thereto. The water collecting and draining pipes 33 and 34 are used to collect the water inside the pipe 32
It is formed so as to diffuse and emit into the inside. Water is naturally filtered and discharged. Due to the natural filtration and the function of the soil bacteria after the natural filtration, most of the pesticides scattered on the lawn 31 are decomposed and rendered harmless. For further decomposition of the pesticide, water may be introduced into the aeration tank as described above.

On the other hand, the lower part of the ground 32 is always kept at a low temperature. Cold air existing in the underground 32 collects and drains pipe 3
Enter into 3,34. When the surface of the lawn 31 is heated to a high temperature, the cool air in the well-shaped drainage pipes 33, 34 rises and is introduced into the flat drainage pipe 1 through the hollow pipe 21 and the connection socket 22. The cold air rises in the flat drainage pipe 1, enters the gap 9 between the opening 7 of the pipe body 2 and the cap member 6, and travels along the longitudinal direction thereof. Further, it is also discharged from the slit-shaped open hole 8 of the tube body 2. Since the flat drainage pipe 1 is buried close to the lawn 31, the road surface of the lawn 31 is cooled by the cool air guided above the flat drainage pipe 1 and is kept in a low temperature state.

Another embodiment of the present invention is shown in FIGS. In the flat type water pipe of FIG. 15, the shapes of the cap member 6 and the engaging portions 12 and 17 are different from those of the above-described embodiment, and the partition member is not provided, and the rib member 3 is used to form the pipe body. It is divided. The fact that the rib member 3 is provided with the through holes is the same as in the above-described embodiment. In FIG. 16, since the upper portion of the tubular body has a wing shape, it is possible to prevent the open hole 8 from being directly clogged with earth pressure. The fixed plate-shaped portion 61 of the cap member 6
There are through holes for water and ventilation. Water or air flows in and out of the tube through the gap 62.

In the present embodiment, the flat drain pipe 1 has the illustrated shape, but the detailed shape is not limited to the illustrated shape. Further, the shape and position of the open hole 8 are not limited to those shown in the drawings, and the shape of the cap member 6 and its locking structure are not limited to those shown in the drawings. On the other hand, the connection socket 22
As long as it can be fitted into the flat drain pipe 1, a pipe having an appropriate connection shape adapted to the deformed pipe shape of the mating side is adopted.
