Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a road structure in which waterway products are installed on both sides of a median strip, which are connected by a communicating pipe at the lower end side wall. It is.

(Prior Art) In the conventional road structure, as shown in FIG. 2, the roadway 1 has a road surface that slopes downward toward the sidewalk section 2, and a waterway product 3 installed adjacent to the sidewalk boundary block 10. There are no permeable openings that allow rainwater to penetrate directly into the ground, and the channel product 3 is connected directly or via a rainwater catchment 8 to an underground rainwater pipe 9.

(Problem to be Solved by the Invention) However, due to poor drainage in such a road structure, rain water tends to accumulate on the sidewalk side of the roadway 1 during rain, and vehicles passing there may splash water or mud. This not only causes a great deal of inconvenience to pedestrians and adjacent buildings, but also blocks or limits the visibility of vehicles on the same lane or on the opposite lane, creating a danger to vehicle driving.

Therefore, an object of the present invention is to provide a road structure that eliminates water splashing and mud splashing caused by vehicles during rain, allows artificial recharge of underground water sources through rainwater infiltration, and is excellent in draining rainwater. .

(Means for Solving the Problems) Hereinafter, using reference numerals in the attached drawings, the road structure of the present invention slopes the roadway 1 downward toward the median strip 4. Waterway products 3, 3 having water permeation openings 6 in the roadway portions on both sides
A communication pipe 5 is connected to the side walls of the left and right waterway products 3, 3.

(Function) Since the road surface of the roadway 1 slopes downward toward the median strip 4, rainwater that falls on the road surface of the roadway 1 is quickly guided to the waterway product 3 adjacent to the median strip 4.
It is discharged. Since rainwater flows back into the ground through the permeable openings 6 provided in all or part of the waterway product 3, the groundwater level is maintained high and artificially recharged as a water source.

In addition, when there is a lot of water flowing in from the roadway 1 on one side and the water level in the waterway product 3 on that side becomes high, excess water moves to the waterway product 3 on the opposite side through the communication pipe 5. The water level in the channel products 3, 3 is automatically balanced.

(Example) In the example shown in FIG. 1, the median strip 4 is formed by a raised earthen embankment, and trees are planted therein.
A water collection lid 12 having a notch and a groove for the inflow of rain water 14 is fitted into the upper end opening of the water channel products 3, 3. The water permeation opening 6 of the waterway product 3 is formed large in the bottom plate;
It can also be provided on the side wall of the. A water permeation opening is also provided in the communication pipe 5 connected to the lower end of the side wall.

In this embodiment, the sidewalk 2 is also formed in a downward slope toward the tree-planted zone on the roadway side, and water permeation openings 6 are also provided in the water channel product 3 installed on the side of the tree-planted zone. In the figure, reference numeral 11 indicates a block bordering the site with the sidewalk 2, reference numeral 13 indicates a building facing the sidewalk, and reference numeral 15 indicates water seeping into the ground.

(Effect of the invention) As described above, in the road structure of the present invention, the roadway 1 is sloped downward toward the median strip 4, and the median strip 4
Since water channel products 3, 3 with permeable openings 6 are installed on both sides, rainwater is guided to the median strip 4 side and quickly permeates back into the ground. This eliminates the nuisance of water and mud splashing on pedestrians, etc.
Driving hazards to oncoming vehicles are also reduced. Furthermore, in the present invention, since the communicating pipe 5 is connected to the lower end side walls of both the left and right waterway products 3, 3, the water level within each waterway product 3, 3 is balanced, and the median strip 4 is balanced. Rainwater is discharged smoothly from the roadways 1 and 1 on both sides without being unevenly distributed.
