[Industrial applications]

 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 that can prevent odors and noise in U-shaped grooves buried along a road from leaking to the outside.

[0002]

[Prior art]

 The U-shaped groove buried along the road will be covered with a cover screen for the purpose of introducing rainwater on the road into the U-shaped groove.

[0003]

[Problems to be solved by the device]

 However, since this type of cover screen is generally formed by assembling rod-shaped steel aggregates in a grid pattern, it has a high air permeability, and the bad smell of the U-shaped groove leaks from the cover screen onto the road, causing environmental problems. Was there. Also, especially on sloping ground, a large amount of rainwater flows down in the U-shaped groove at high speed in a turbulent state during heavy rain, so the noise is extremely large, and this noise leaks to the outside from the cover screen, causing noise pollution. It was in the actual situation causing it. Therefore, 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]

[Means for Solving the Problems]

 To this end, the present invention is one in which the seat 5 is oscillated vertically at the upstream end of the cover screen 3.

[0005]

[Action]

 According to the above configuration, the lower end portion of the sheet 5 hanging down from the cover screen 3 constantly contacts the water surface so as to be swept by the water flow, and shuts off the inside of the U-shaped groove 1, so that a bad odor inside the 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 inflow of rainwater on the road into the U-shaped groove 1 are not hindered. Instead, it can function as a cover screen according to the intended purpose.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an inclined view of a gutter provided along a road, FIG. 2 is a longitudinal sectional view, and FIG. 3 is a lateral sectional view. The gutter is constructed by covering a U-shaped groove 1 buried underground with a cover plate 2 and a cover screen 3.

Flexible and flexible sheets 5 and 6 are vertically oscillatably provided at the upstream end and the downstream end of the cover screen 3. 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 the bottom surface of the U-shaped groove 1 can be grounded. Further, the length of the downstream sheet 6 is considerably shorter than that of the upstream sheet 5, and the lower end portion thereof is located higher than the bottom surface of the U-shaped groove 1.

A solid line in FIG. 2 shows a state where the water level H1 is low. The chain line indicates that the water level H2 is high during heavy rain. The inside of the U-shaped groove 1 is completely blocked by the sheet 5, and is completely blocked by the sheet 6. When the water level H1 is low, the lower end of one of the sheets 5 is landing on the water surface, and the other sheet 6 is in a suspended state, blocking the inside of the U-shaped groove 1 to cover the odor inside. The screen 3 is prevented from leaking onto the road. When the water level H2 is high and the rainwater is flowing down in the U-shaped groove 1 in the direction of the arrow N, the sheet 5 is extended by the water flow, as shown in FIG. The seat 6 also extends to the downstream side.

In this state, the seat 6 is grounded on the seat 5, and the two seats 5 and 6 substantially seal the space right below the cover screen 3. Therefore, it is possible to completely prevent the malodor in the U-shaped groove 1 from leaking from the cover screen 3 onto the road. In addition, it is possible to block the leakage of water noise to the outside. Even if the water level fluctuates in this way, the lower end of the seat 5 can always land on the surface of the water, preventing internal malodors and noise from leaking to the outside. Further, in this state, the seats 5 and 6 can fully perform their intended functions as the cover screen 3 without blocking rainwater on the road from flowing into the U-shaped groove 1 from the cover screen 3. It should be noted that the downstream seat 6 is not always necessary, but if this seat 6 is not provided, a bad odor will leak to the outside slightly from the cover screen 3 as indicated by the broken line arrow a, so it is desirable to provide this seat 6 as well.

FIG. 4 shows another embodiment. In this product, a rod-shaped float 7 is attached to the lower ends of the sheets 5 and 6. The float 7 is made of foamed resin, for example. If the float 7 is provided in this way, there is an advantage that the lower end portions of the seats 5 and 6 can be reliably floated on the water surface, but on the other hand, a piece of wood in running water hits the float 7. There is also a drawback that it can be damaged.

FIG. 5 shows still another embodiment. Instead of the flexible sheets 5 and 6, the sheets 5A and 6A made of a hard plate such as a styrene foam plate or a vinyl chloride resin plate are swingably attached to the lower surface of the cover screen 3 via a hinge portion 8. It is suspended. Therefore, as shown in the drawing, the seats 5A and 6A swing in response to the changes in the water levels H1 and H2, and the same effect as that of the first embodiment can be obtained.

[0012]

[Effect of device]

 As described above, according to the present invention, since the seat 5 is oscillated vertically at least at the upstream end of the cover screen 3, the bad odor or noise in the U-shaped groove 1 leaks from the cover screen 3 to the outside. Can be prevented. Especially, since the lower end of the seat 5 can be floated on the water surface by flowing into the water flow, even if the water level fluctuates, it can always be grounded on the water surface and prevent odors and noise from leaking to the outside. No. 5 does not prevent rainwater on the road from falling into the U-shaped groove 1 from the cover screen 3 and completely achieves the intended purpose as a cover screen.
