BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter buried in a shoulder of a drainage pavement.

[0002]

2. Description of the Related Art A drainage paved road is a road having a water-permeable layer composed of an asphalt mixture having a high porosity as a surface layer and an impermeable layer which does not allow water to permeate thereunder. According to this drainage paved road, water due to rainfall or the like permeates the surface layer, moves downward, and flows at the boundary between the surface layer and the base layer. And this water is a water channel (gutter, canal, etc.) that has a drainage function provided on the shoulders of the road, roadside strips, etc.
Be drained to. Therefore, the drainage paved road is quickly drained on the road surface and is also excellent in noise reduction when the vehicle is running. For this reason, drainage paved roads have been widely adopted for general roads, expressways, and the like.

Conventionally, gutters having various structures have been disclosed as gutters applied to such drainage paved roads. A typical example is a side groove having a substantially box-shaped, U-shaped, or circular cross-section, which has a side wall and a bottom portion, and a side wall of the side wall and a drain hole that communicates with a drainage channel formed inside the side groove. An example is one in which the water port) is provided in an oblique direction (see FIG. 6).

However, since this type of gutter is in direct contact with the vehicle because its upper surface is exposed at the same height as the road surface, it is easily worn and deteriorated. Further, along with this, noise is generated when the vehicle is running, and there is a problem that the noise reduction effect originally possessed by the drainage paved road is not sufficiently exerted.

Further, similarly to the above, a drainage hole is formed in the side wall in an oblique direction, and a gutter whose upper surface is completely buried under the ground,
That is, when the underdrain is used, the above problems can be solved. However, the drainage channels inside the gutters may contain mud, soil, sand,
When dust, dust, tire debris, and other debris (hereinafter referred to as "sand and the like") are accumulated and clogged, the only means for cleaning the drainage channel is to dig a gutter. This is problematic in that repair costs are high considering that current drainage paved roads may become clogged within 1-2 years and repair work may be performed regularly. It was

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its main purpose is to reduce repair costs, prevent wear and deterioration over a long period of time, and further improve drainage collection and drainage effects. To provide an excellent gutter.

[0007]

The gutter of the present invention is a gutter that is buried in series along the shoulder of a drainage paved road in which a water-permeable surface layer is formed on the surface of an impermeable underlayer. Part of the upper part is a gutter that is constructed by being covered with the surface layer, and this gutter is composed of a side wall and a bottom part, and a box body in which a drainage channel is formed, and the upper part of this box body It is composed of a flat plate-shaped lid body that is detachably attached by means of a first drainage hole that connects the surface layer and the drainage channel when the lid body is buried, and the ground and drainage. The second drainage holes communicating with the passages are provided at predetermined intervals along two substantially parallel straight lines, and these drainage holes vertically penetrate the upper and lower surfaces of the lid body.

According to the above structure, the upper part of the gutter is partly covered by the surface layer of the drainage paved road, and therefore the upper part of the gutter does not come into direct contact with the vehicle, so that it is worn and deteriorated over a long period of time. Since it is difficult and noise is not actively generated, it is possible to sufficiently exhibit the noise reduction effect that the drainage pavement originally has when the vehicle is running.
Also, because the lid of the gutter is detachably attached to the box, you only have to remove the water-permeable surface layer that covers the top of the lid at the time of repair, so that the drainage can become clogged Can be easily removed, and the repair cost can be reduced as compared with the prior art.

Further, according to the present invention, rainwater and the like that have permeated into the boundary surface between the surface layer and the underlayer are mainly collected through the first drain holes and flow between the rainwater and the like on the road surface flowing toward the gutter and the surface layer. Rainwater leaking from the side edge is mainly collected through the second drain hole. For this reason, it is possible to increase the water collecting / discharging effect because the water collecting area can be increased because the number of water collecting points is larger than that in the conventional technique. Further, since the first drain hole and the second drain hole provided in the lid body penetrate in a direction perpendicular to the upper and lower surfaces of the lid body, the drain hole is provided obliquely on the side wall of the box body. Compared with the conventional technique, the soil and the like that have permeated the permeable layer are less likely to stay inside the drainage holes. Therefore, even if sediments flow into the gutters, they are smoothly guided to the drainage channel without staying inside the drainage holes, and sediments are retained at the boundary between the surface layer and the underlayer for a long time. Therefore, the clogging of earth and sand at the lower surface layer or the boundary surface between the surface layer and the underlayer is suppressed.

In addition to the above structure, in the gutter of the present invention, the upper surface of the lid is adjacent to a height position on substantially the same plane as the boundary surface between the surface layer and the underlayer constituting the drainage pavement. Are preferably arranged. By arranging the gutters in this way, rainwater and the like that have penetrated into the surface layer can be collected to the maximum extent, so that the water collection / drainage effect can be further enhanced. Further, for the same purpose, in the gutter of the present invention, in addition to the above-mentioned configuration, the second drain hole provided in the lid may be arranged near the side edge of the surface layer forming the drainage pavement. preferable.

Further, in the drainage structure of the present invention, the gutter according to any one of the above is arranged in series along the shoulder of a drainage paved road in which a water-permeable surface layer is formed on the surface of an impermeable underlayer. Which is a drainage structure buried in the upper part of the gutter,
And, in the part of the drainage paved road that is not covered by the surface layer, rainwater that flows in or out from the road surface and side edges in the surface layer is collected, and then drained toward the second drain hole provided in the gutter. A cover member for fitting is fitted and configured. In the present invention, by using such a lid member together with the side groove, it is possible to provide a novel drainage structure in which construction of the road shoulder has been completed.

BEST MODE FOR CARRYING OUT THE INVENTION First, the gutter of the present invention is preferably applied as a gutter that is buried in series along the shoulder of a drainage pavement as described above. Further, the gutter of the present invention is particularly preferably applied to a drainage pavement road in which the gutter is buried in a road shoulder and then a part of the upper part of the gutter is covered with the surface layer.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing an example of the side groove 1 of the present invention. The gutter 1 has a side wall 21 and a bottom portion 22.
And a drainage channel 2 formed inside the box
3 and a flat plate-like lid body 3 which is detachably attached to the upper part of the box body, and is configured as a substantially elongated rectangular parallelepiped. The gutter 1 is not particularly limited as long as it is made of concrete as a raw material like a general gutter. Further, the size is not particularly limited as long as it is similar to that of a general side groove. For example, length 250-450 mm, width 25
Examples of generally preferable sizes are 0 to 450 mm and depths of 1500 to 2500 mm. Further, in FIG. 1, the drainage channel 23 has a quadrangular cross section, but is not particularly limited to a quadrangular shape as long as it can smoothly collect and drain rainwater and the like, and a known shape such as a circular shape or a U shape. Can be adopted.

In the series direction of the lid body 3 (the x direction in FIG. 1),
A first drainage hole 31 and a second drainage hole 32 are provided along two substantially parallel straight lines. These drain holes 31, 32
Both have a role of collecting rainwater and the like and guiding it to the drainage channel 23 inside the box 2. As an embodiment capable of efficiently exerting such a role, there can be mentioned a mode in which a plurality of small drain holes formed in a predetermined shape are provided at predetermined intervals as shown in FIG. When such a form is adopted, it is preferable that the drain holes 31 and 32 have an outer diameter of 40 to 60 mm in order to enhance the effect of collecting and draining water. Further, the shapes of the drain holes 31 and 32 are not particularly limited, and may be triangular, quadrangular,
Various shapes such as a polygon, a fan shape, a semicircle, and a circle can be adopted.

As another preferred embodiment in which the roles of the drainage holes 31 and 32 can be effectively exhibited, a plurality of elongated drainage holes can be adopted along the series direction of the lid 3. By adopting such a form, although the strength of the lid 3 is slightly reduced as compared with the first embodiment, the water collection and drainage effect can be enhanced. Which form should be adopted may be appropriately designed according to the type of road to be constructed.

Subsequently, the drainage holes 31 provided in the lid body 3,
The positional relationship in the lateral direction of 32 (the y direction in FIG. 1) and the opening direction will be described with reference to the working state of the gutter 1. Figure 2
[Fig. 2] is a cross-sectional view showing an example in which the side groove 1 of Fig. 1 is constructed.
The drainage pavement 4 to the right of the gutter 1 in the figure has a drainage surface layer 4 on the surface of an impermeable underlayer 42 that does not allow water to penetrate.
1 was constructed. According to the drainage pavement 4, rainwater first penetrates the surface layer 41 downward, reaches the boundary surface 43 between the surface layer 41 and the underlayer 42, and then is buried in the shoulder of the drainage pavement 4. It flows toward the gutter 1.
On the other hand, when the amount of rainfall is large enough to exceed the drainage capacity of the surface layer 41, rainwater or the like that cannot penetrate into the surface layer 41 will pass through the road surface 4 of the surface layer 41.
It flows on the road 1a in the shoulder direction and is drained to the side groove 1.
Although the drainage pavement road 4 is divided from the sidewalk 7 by the curb block 6 in FIG. 2, the road to which the gutter 1 of the present invention is applied is limited to the road on which the curb block 6 is installed. It is also applied to a road where the curb block 6 is not installed.

According to the present invention, the gutter 1 including the lid 3 is buried in the underground portion of the road shoulder adjacent to the drainage pavement 4, and the upper portion of the lid 3 of the gutter 1 is partially covered with the surface layer 41. On the other hand, it is preferable that the portion other than the portion covered with the surface layer 41 communicates with the ground. That is, in the present invention, the surface layer 41 of the drainage pavement 4 is constructed by extending a little to the shoulder. As a result, the gutter 1 (that is, the lid 3) is prevented from coming into direct contact with the vehicle, and is thus less likely to wear and deteriorate over a long period of time. Further, since noise is not positively generated, it is possible to effectively exhibit the noise reduction effect that the drainage pavement 4 originally has when the vehicle is running.

In the present invention, the first drainage hole 31 is arranged in the upper portion of the lid body 3 covered with the surface layer 41 so that the surface layer 41 and the drainage channel 23 formed inside the box body 2 communicate with each other. Preferably. With such a configuration, when rainwater or the like that has permeated the boundary surface 43 between the surface layer 41 and the base layer 42 moves in the road shoulder direction, the rainwater or the like can reliably pass through the first drainage hole 31 and the drainage channel 23. (See FIG. 3). Then, the second drain hole 3 is formed in the portion not covered with the surface layer 41.
It is preferable to dispose 2 so that the ground and the drainage channel 23 communicate with each other. With such a configuration, rainwater or the like that has moved in the shoulder direction on the road surface 41a when the amount of rainfall is large is reliably guided to the drainage channel 23 through the second drainage hole 32. Further, in the surface layer 41 portion covering the space between the first drain hole 31 and the second drain hole 32, the rainwater or the like that has penetrated downward from the road surface 41a of the surface layer 41 portion, the first drain hole 3
1 is led to the drainage channel 23, or exudes from the side end 41b of the surface layer 41 and passes through the second drainage hole 32 to drainage channel 2
Guided by 3.

When the side groove 1 of the present invention is used as described above,
The boundary surface 43 immediately above the first drainage hole 31, the side edge 4 of the surface layer 41
Rainwater or the like can be collected from 1b and the road surface 41a. Therefore, compared with the conventional gutter which collects water only from the side edge of the surface layer and the road surface, the gutter of the present invention can have a wider water collecting area.

In the present invention, the side edge 41 of the surface layer 41
b is not particularly limited as long as it is constructed so as to cover between the first drain hole 31 and the second drain hole 32 in general. However, in the present invention, if rainwater or the like that has exuded from the side end 41b can be promptly guided to the second drain hole 32,
Since it can be said that it is preferable from the viewpoint of the drainage effect, it is more preferable to construct the side end 41b at a position as close as possible to the second drainage hole 32 from this viewpoint, and as shown in FIG. It is particularly preferable to apply the above method.

Here, in the present invention, it is preferable that the first drain hole 31 and the second drain hole 32 are configured to vertically penetrate the upper and lower surfaces of the lid body 3. With such a structure, if the surface layer 41 is infiltrated with earth and sand or the road surface 4
Even if soil or the like flows from 1a and reaches the gutter 1, it is difficult for the soil or the like to stay inside the drain holes 31 and 32. Therefore, even if soil or the like flows into the gutter 1, since they are smoothly guided to the drainage channel 23, rainwater or the like is also smoothly guided to the drainage channel 23. Further, since sediment does not accumulate on the boundary surface 43 between the surface layer 41 and the underlayer 42 for a long period of time, clogging of the boundary surface 43 with sediment is suppressed. On the other hand, in the prior art, since the drainage holes are obliquely provided on the side walls of the gutters, in the above case, the earth and sand are likely to stay inside the drainage holes, which prevents rainwater and the like from being guided to the drainage channel. . Furthermore, since soil and the like are likely to stay on the boundary surface 43, clogging is less likely to be suppressed as compared with the present invention.

Further, in the present invention, the height position of the upper surface 33 of the lid is not particularly limited as long as it is arranged below the road surface 41a of the surface layer 41, but the effect of collecting rainwater or the like is maximized. In order to do so, it is preferable that the boundary surface 43 between the surface layer 41 and the base layer 42 is arranged at a height position substantially on the same plane.
That is, by arranging the upper surface 33 of the lid body at such a height position, it is possible to collect the most amount of rainwater and the like that have penetrated to the boundary surface 43, so that the water collection / drainage effect can be further enhanced.

Further, in the present invention, it is preferable that the lid body 3 is detachably attached to the box body 2. Generally, it is inevitable that sediment etc. will be accumulated in the drainage channel after a certain period has elapsed after construction of the gutter, and it is necessary to remove the sediment etc. from the drainage channel when a certain amount is accumulated. According to the present invention, the lid body 3 can be easily removed by peeling off the surface layer 41 portion covering a part of the lid body 3, so that the earth and sand clogged in the drainage channel 23 can be easily removed. Therefore, the repair work can be performed in a shorter time as compared with the conventional technique, and the repair cost can be reduced.

Further, in the present invention, a portion of the drainage pavement 4 which is not covered by the surface layer 41 of the drainage pavement 4 (hereinafter referred to as "groove portion") flows from the road surface 41a of the surface layer 41. Alternatively, the drainage structure can be formed by fitting the lid member 5 for draining rainwater or the like exuding from the side end 41b toward the second drainage hole 32.

FIG. 4 is an external perspective view showing an example of the lid member 5, and FIG. 5 is an exploded perspective view of the constituent members of the lid member shown in FIG. The lid member 5 includes an upper member 51 having a substantially U-shaped cross section and a lower member 52 having a substantially U-shaped cross section as constituent members,
It is configured by fitting and mounting each opening side. The lid surface portion 51 a of the upper member 51 includes a plurality of bar members 51.
A large number of gaps through which rainwater and the like are smoothly drained are provided by combining b vertically and horizontally, and the wall surface portions 51c on both sides thereof are provided with a plurality of water passage holes 51d through which rainwater and the like can pass. Further, the lower member 52 has a water passage hole 52 through which a rainwater or the like can pass through the lower surface portion 52a and the side wall portions 52b on both sides thereof.
A plurality of c and 52d are provided. In the present invention, when the above-mentioned upper member 51 and the lower member 52 are fitted together, the water passage holes 51d, 52d provided in the respective side wall portions 51c, 52b,
It is preferable to design so that 52d overlaps. Also,
In the present invention, when the lower member 52 is fitted into the groove portion, it is preferable to design the water passage hole 52c and the second drain hole 32 of the side groove 1 immediately below the water passage hole 52c to overlap each other.

The lid member 5 preferably has a size such that it can be fitted into the entire groove portion, and when fitted, the lid surface portion 51a and the road surface 41a of the surface layer adjacent to the lid surface portion 51a are arranged on substantially the same plane. preferable. Further, when the lid member 5 is fitted in the groove portion, if there is a little gap on the sidewalk 7 side of the lid member 5, the surface layer 41 used for the drainage pavement 4 may be embedded in the gap portion (see FIG. 2). ). According to the lid member 5, rainwater or the like flowing into the road shoulder from the road surface 41a is collected through the gap provided in the lid surface portion 51a of the upper member 51, and then drained to the drainage channel 23 of the gutter 1. On the other hand, rainwater or the like exuding from the side edge 41b of the surface layer 41 is collected through the water passage holes 51d and 52d provided in the side wall portions 51c and 52b of the lid member 5, and then drained to the drainage channel 23 of the gutter 1. To be done.

By thus fitting the lid member 5 to form the drainage structure, the side groove 1 is formed even on the road surface 41a.
Since the state of water collection and drainage can be checked at a glance, it is possible to easily determine whether or not there is a need for repairs due to the accumulation of sediment. It should be noted that, as the shape of the lid surface portion 51a of the above-mentioned upper member 51, it can be generally said that a lattice shape is preferable, but the visibility of the inside of the lid member 5 from the road surface 41a is excellent, and rainwater or the like can be collected smoothly. If drainage is possible, a plurality of water passage holes having a certain area, such as a circular shape, an elliptical shape, and a square shape, may be provided. Further, in the present invention, when the lid member 5 is fitted into the groove portion for construction, the lid member 5 and the lid body 3 of the gutter 1 below the lid member 5 can be fixed. Any known method may be used as the fixing means, and the fixing means is not particularly limited. For example, the fixing means may be detachably fixed with a bolt or the like through an L-shaped bracket or the like, or may be fixed to the lid member 5 in advance. May be integrally provided.
