Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter cover screen, and more particularly, to a gutter cover screen capable of preventing odor and noise in a U-shaped groove buried along a road from leaking to the outside.

[0002]

2. Description of the Related Art A U-shaped groove buried along a road is covered with a cover screen for introducing rainwater on the road into the U-shaped groove.

[0003]

However, since this kind of cover screen is generally formed by assembling bar-shaped steel members in a grid or the like, the cover screen has a high air permeability. Leaked, causing environmental problems. Also, particularly on a slope, a large amount of rainwater flows down in a U-shaped groove in a turbulent state at a high speed during heavy rain, so that the noise is extremely large. I was in the situation. Accordingly, an object of the present invention is to provide a gutter cover screen which does not lose its function as a cover screen and has a deodorant function and a soundproof function.

[0004]

According to the present invention, a seat 5 is provided at the upstream end of the cover screen 3 so as to swing freely.

[0005]

According to the above construction, the lower end of the sheet 5 hanging down from the cover screen 3 always flows on the water surface in such a manner as to be flushed with the water flow, and shuts off the inside of the U-shaped groove 1. And noise can be prevented from leaking to the outside. Moreover, since the seat 5 is swingable, even if the inside of the U-shaped groove 1 is blocked by this, the flow of water and the falling of rainwater on the road into the U-shaped groove 1 are not hindered. , And can function as the intended cover screen.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a gutter provided along a road,
2 is a longitudinal sectional view, and FIG. 3 is a transverse sectional view. The gutter is placed on a U-shaped groove 1 buried underground, and a cover plate 2 and a cover screen 3
It is built with a lid.

At the upstream end and the downstream end of the cover screen 3, bendable flexible sheets 5 and 6 are vertically suspended to be swingable. As the sheets 5 and 6, those having a small specific gravity, such as a film-shaped synthetic resin sheet, a thin rubber sheet, and a foamed resin sheet, are applied. The length of the sheet 5 on the upstream side is longer than the depth of the U-shaped groove 1 and the length of the cover screen 3, and can be grounded on the bottom surface of the U-shaped groove 1. The length of the downstream sheet 6 is considerably shorter than that of the upstream sheet 5, and the lower end thereof is located higher than the bottom surface of the U-shaped groove 1.

The solid line in FIG. 2 shows a state where the water level H1 is low. The chain line indicates a high water level H2 during heavy rain. The inside of the U-shaped groove 1 is completely shut off by the sheet 5,
Further, the sheet 6 is incompletely blocked. Water level H1
Is low, the lower end of one of the sheets 5 has landed on the water surface, and the other sheet 6 is in a suspended state,
The inside of the U-shaped groove 1 is blocked, and the odor inside the cover screen 3
From leaking onto the road. When the water level H2 is high and the rainwater is flowing down the U-shaped groove 1 in the direction of the arrow N, the sheet 5 is extended by the water flow to extend downstream as shown in FIG. Sheet 6
Also extends long downstream.

In this state, the sheet 6 is grounded on the sheet 5, and the area immediately below the cover screen 3 is substantially sealed by the two sheets 5 and 6. Therefore, it is possible to completely prevent the odor in the U-shaped groove 1 from leaking from the cover screen 3 onto the road. In addition, the noise of the water flow can be prevented from leaking to the outside. Even if the water level fluctuates in this way, the sheet 5
The lower end of the is always immersed in the water surface to prevent internal odor and noise from leaking to the outside. Further, in this state, the intended function of the cover screen 3 can be fully exhibited without the sheets 5, 6 preventing rainwater on the road from flowing into the U-shaped groove 1 from the cover screen 3. Although the downstream sheet 6 is not always necessary, this sheet 6
When there is no odor, the odor leaks slightly from the cover screen 3 to the outside as shown by the dashed arrow a.
It is desirable to provide also.

FIG. 4 shows another embodiment. In this case, a rod-shaped float 7 is attached to the lower end of the sheets 5 and 6. The float 7 is made of, for example, a foamed resin. If the float 7 is provided in this manner, the sheets 5, 6
There is an advantage that the lower end of the float can be reliably floated on the water surface.
There is also a disadvantage that it can be damaged by hitting.

FIG. 5 shows still another embodiment. In this embodiment, sheets 5A and 6A made of a hard plate such as a styrene foam plate or a vinyl chloride resin plate are swingably mounted on the lower surface of the cover screen 3 via a hinge portion 8 instead of the flexible sheets 5 and 6 described above. It is suspended. Therefore, as shown in the figure, the sheets 5A and 6A swing in response to changes in the water levels H1 and H2, and the same operation and effect as those of the first embodiment can be obtained.

[0012]

As described above, in the present invention, since the sheet 5 is swingably suspended at least at the upstream end of the cover screen 3, the odor and noise in the U-shaped groove 1 are reduced. 3 can be prevented from leaking to the outside. In particular, since the lower end of the sheet 5 can be flown by the water flow and float on the water surface, even if the water level fluctuates, it always contacts the water surface,
The odor and noise can be prevented from leaking to the outside, and the sheet 5 does not prevent rainwater on the road from falling into the U-shaped groove 1 from the cover screen 3 and the intended purpose of the cover screen. Can also be achieved completely.
