Description of the Related Art For example, a gutter is provided at a road shoulder which is a boundary between a road and a sidewalk, and rainwater on the road flows to the side of the sidewalk because the road is formed to be inclined downward toward the sidewalk. Guided inside and drained. Although the upper surface of the gutter is usually almost closed, a concrete or cast iron water-collecting road lid for collecting and draining rainwater is installed at an appropriate location, and the water flows to the sidewalk side. Rainwater
It is led directly into the gutter through the water inlet of this water-covering road lid, or flows into the rainwater basin configured below and is separated from the pebbles and trash that flowed in at the same time and flows out into the gutter. (Some rainwater basins are configured to allow some of the inflowing rainwater to penetrate into the ground). As the water-collecting road surface lid, those formed in a lattice shape and provided with a number of relatively short water holes on the entire surface are widely used, but a plurality or a large number of water holes formed to extend long are used. The road cover for water collection provided here is also used.

のとなる。By the way, the rainwater flowing toward the side of the sidewalk on the road includes relatively large foreign matters such as fallen leaves, but the fallen leaves and the like flow into the gutter from the water passage of the lid together with the rainwater. For example, it accumulates at the bent portion of the gutter and hinders the smooth flow of rainwater. Also, if a rainwater basin is installed under the road cover for collecting water,
A large amount of fallen leaves and the like fall into the trash catch baskets of the rainwater basin in a short period of time and accumulate, causing the rainwater / foreign matter separation function of the rainwater basin to be reduced or lost, so frequent maintenance is required, and excessive road management labor and It costs money. If the water passage is formed to be narrow, large foreign matters such as fallen leaves are unlikely to pass through the narrow water passage, and the fall of leaves and the like are easily prevented from easily accumulating in the gutters. And if this water inlet is formed so as to be orthogonal or almost orthogonal to the direction crossing the roadway, or to cross at a large angle, rainwater flowing from the roadway side will be totally received by the water inlet, and Since it can be poured into the gutter, it also has an excellent rainwater recovery function.

されてしまう。However, in such a water collecting road surface cover, the water passage is formed so as to be perpendicular to the surface of the cover, that is, the inner wall surface of the water passage is perpendicular or almost perpendicular to the surface of the cover. Therefore, it is not always possible to prevent a large number of fallen leaves and the like contained in rainwater flowing from the roadway side from being drawn into the water passage and falling into the rainwater basin or the like. That is, as shown in FIGS. 8 and 9, when the water inlet 100 is provided along the road shoulder A, the road or the road B (the center side of the road or the road B).
The turbulent flow of the rainwater from the turbulence occurs on the inner wall surface 102 on the road end side or the rear side of the water inlet 100, and as a result, the tip of the fallen leaves C contained in the rainwater enters the water inlet 100 and the inner wall surface 102. Collides with the upper end of the Since the tip of the fallen leaves C moves downward while rubbing the substantially vertical inner wall surface 102 as it is, the fallen leaves C etc.
And thus the water outlet 100
The effect of preventing the fallen leaves C and the like from being drawn by reducing the width is not so effective. And fallen leaves C
If the water inlet 100 is formed to be extremely thin in order to sufficiently prevent the drawing in of rainwater, the smooth recovery function of rainwater will be impaired.

成することができる。According to the present invention, there is provided a water-collecting road lid according to the present invention, in which a road shoulder (a median strip) is formed so that the surface of the lid is the same or almost as high as the road shoulder. A road cover for collecting water provided with a plurality of water inlets, which is installed in a central portion of the road on the provided road). At the water inlet, the inner wall surface on the road end side has fallen leaves and the like. It is inclined downward toward the road (toward the center of the road or toward the road main body) with respect to the surface of the lid so as to prevent the intrusion of foreign matter. In many cases, the inner wall surface at the end of the road is inclined downward toward the road toward the shoulder of the road. The water passage is preferably formed to be narrow in width, but it is effective to form the water passage as an elongated water passage slit. In the present invention, even if the tip of fallen leaves or the like contained in rainwater flowing from the road enters the water inlet and collides with the upper end of the inner wall, the inner wall on the road end side or the rear side of the water inlet is covered with a lid. Since it is inclined downward toward the road with respect to the surface and inclined in the opposite direction to the traveling direction of the fallen leaves and the like, the tips of the fallen leaves and the like are unlikely to move downward while rubbing the inner wall surface. Therefore, fallen leaves and the like fall out of the water outlet. Further, in the present invention, it is not necessary to widen the inlet of the water inlet or the upper surface opening itself (in some cases, widening) in configuring the pull-in preventing structure, so that pull-in of fallen leaves and the like can be more effectively prevented. In addition, it is preferable that the water inlet extends linearly, and it is effective that the water outlet is formed so as to extend at a right angle or an appropriate angle to the crossing direction of the road, preferably at a large angle. Further, in the present invention, it is not necessary to incline the inner wall surface on the rear side of all the water inlets downward toward the road with respect to the lid surface. For example,
A plurality of or many long water holes are formed from the road side to the road end side perpendicular to the road cross direction, and the rear inner wall surface of the plurality of water holes located on the road side (or the water hole itself) Incline downward and toward the road with respect to the lid surface, and make one or more water inlets located on the road edge side rear inner wall surface (or the water inlet itself) perpendicular or almost perpendicular to the lid surface. Can be formed.

側に傾斜させるのがより好ましい。[0007] Of the inner wall surfaces of the water inlet, only the inner wall surface on the rear side is inclined downward and toward the road, and the inner wall surface on the front side is formed so as to be kept perpendicular or almost perpendicular to the lid surface. Although it is possible, the width of the outlet of the water inlet or the bottom opening is narrowed, and the smooth drainage of rainwater is slightly weakened. Therefore, in the present invention, the water inlet itself is placed on the lid surface,
Therefore, in many cases, it is more preferable to incline downwardly with respect to the road shoulder surface toward the road.

When a large amount of fallen leaves are included in the rainwater flowing along the downward slope in the cross direction of the road during rainfall, the rear end (road end side) of the lid surface of the water collecting road surface lid There is a possibility that more fallen leaves and the like will accumulate on the front side than before, blocking the water passage and obstructing the flow of rainwater into the rainwater basin or gutter. Therefore, the central part or almost the central part of the lid surface is formed as a convex non-deposited part, preferably as a spherical convex non-deposited part, so that fallen leaves and the like are not deposited on the central part or substantially central part. Keep it. Even if fallen leaves and the like accumulate on the lid surface, the rainwater flows into the rainwater basin or the gutter through the water inlet at the non-accumulation portion where no fallen leaves and the like are accumulated.

うにしておくのが効果的である。Further, it is preferable that the water-collecting road surface cover of the present invention is configured such that a water port non-forming portion extending along the road shoulder with an appropriate width is provided on the road end side. The road end side of the road cover for collecting water is a part where rainwater collects from the road side and, for example, the sidewalk side, and also a part into which the rainwater flowing along the road end along the gradient in the length direction of the road flows. It is a place where a large amount of fallen leaves are concentrated. Therefore, if a water passage that is large enough to draw fallen leaves and the like is formed on the road end side of the water-collecting road cover, some of the large amount of fallen leaves that cannot be ignored is drawn into the water passage. There is a risk that it will. In view of this, it is preferable to provide a water port non-forming portion having no water port formed on the road end side of the water collecting road surface cover and extending along the road shoulder with an appropriate width. Then, a small hole for water flow that allows only rainwater and pebbles and earth and sand to pass through and is provided in the part where the water outlet is not formed, so that the function of the water collecting road surface cover that guides rainwater into the rainwater basin or gutter is not reduced. It is effective to keep it.

A downwardly extending edge frame 3 is fitted therein and is installed so that it can be removed and the lid surface 5 is flush with the surface of the road shoulder A. The rainwater basin lid 1 has a water passage slit 7 (water passage) extending linearly in a direction perpendicular to the direction crossing the road B, that is, in a direction along the road shoulder A from the front edge portion 9 to the rear end portion 11 ( That is, before the edge of the road edge or the rear edge)
, And each of the water slits 7 extends from one side edge 13 to the other side edge 15 of the rainwater basin lid 1.
The slit forming portion 17 extends in the direction (width direction) along the shoulder A to form a rectangular slit forming portion 17, and the width direction central portion of the slit forming portion 17 near the rear end 11 of the surface 5 (the lid for rainwater basin) 1 (central portion 1) is formed as a gently convex portion having a spherical shape, and forms a non-deposited portion 19. The slit forming portion 17 is formed to be relatively thick (that is, thick in the vertical direction) in order to compensate for a decrease in strength due to the formation of the water passage slit 7. For example, a dividing wall is formed at the center in the longitudinal direction of the water-passing slit 7 extending continuously to form the water-passing slit 7.

Is formed about one-fourth of the length. The boundary 21 between the surface 5 of the slit non-forming portion 11 and the surface 5 of the slit forming portion 17 is formed as a bent portion, and the surface 5 of the slit non-forming portion 11 is the surface 5 of the slit forming portion 17 (except for the non-deposition portion 19). Surface) and extends rearward with a slight upward inclination. Therefore, the rainwater basin lid 1 is installed such that the slit forming portion 17 is inclined downward toward the rear and along the slope of the shoulder A of the road B, but the slit non-forming portion 11 is substantially horizontal in the installed state. And a large amount of fallen leaves C can be stably deposited.

3 is provided so as to open to the upper end surface of the protruding portion 25 provided on the surface 5 of the slit non-forming portion 11. Therefore, the upper surface opening of the small hole 23 for water passage is located slightly above the surface 5 of the non-slit portion 11. The diameter of the small holes 23 for water passage is preferably 10 mm to 30 mm so that there is almost no possibility that the fallen leaves C and the like will be drawn in, and that it has a sufficient function of allowing rainwater to pass and drop. Further, as shown in FIG. 4, a groove 26 may be formed between the rows of small holes, and a step may be formed at the upper opening of the small holes 23 for water passage (small holes 23 for water passage). Is open on the surface 5). With such a configuration, it is possible to prevent the fallen leaves C and the like from completely blocking the upper surface opening of the small water passage hole 23, thereby preventing the inflow of rainwater.

It separates and moves in the direction of the slit non-forming portion 11. Therefore, since the fallen leaves C do not accumulate on the non-accumulation portion 19, even if the fallen leaves C accumulate on the other surface 5 of the slit forming portion 17 of the rainwater basin cover 1, the rainwater basin cover 1 The rainwater heading toward the central portion passes through the water-passing slit 7 of the non-deposition portion 19 and smoothly flows down into the rainwater basin D.

Therefore, the inner wall surface 27 on the rear side of the water passage slit 7 is inclined in the opposite direction to the traveling direction of the fallen leaves C, and even if the tip F of the fallen leaves C collides with the upper end of the inner wall surface 27 on the rear side, the tip F remains It is difficult to descend along the inner wall surface 27 and jumps out of the water passage slit 7. The water passage slit 7 or the inner wall surface 27 is preferably inclined at 15 to 45 degrees toward the road B with respect to a direction perpendicular to the lid surface 5. If the inclination is less than 15 degrees, an effective function of preventing fallen leaves C cannot be expected.
If it exceeds 5 degrees, smooth running of rainwater is hindered.

とを防止できる。In the slit forming section 29 of another configuration, the rear inner wall surface 33 of the two rear water slits 31 is formed substantially perpendicularly to the lid surface 5 together with the front inner wall surface. The inner wall surface 37 on the rear side of the water passage slit 35 is inclined downward toward the road B similarly to the water passage slit 7. By forming in this way, the fallen leaves C and the like included in the rainwater flowing from the road B side are stopped on the lid surface 5 without being drawn into the front-side water passage slit 35, or the rear of the lid surface 5 However, since the fallen leaves C and the like that have moved behind the lid surface 5 move at a low speed, they are drawn into the water slit 31 even if the inner wall surface 33 on the rear side of the water slit 31 is not inclined. Is unlikely to be And, since the inner wall surface on the front side of the water passage slit 31 is not inclined downward toward the road B side, the fallen leaves C and the like that have moved slightly behind the lid surface 5 so as to return to the front side by rainwater flow or waves. Can be prevented from being drawn into the water passage slit 31.
