Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a road drainage device that serves as both a curb and a drainage ditch for a motorway.

(Prior Art) A road drainage system is required to be able to function as a drainage ditch with sufficient resistance against certain types of collisions with automobiles.

As shown in FIGS. 6 to 8, a conventional drainage device of this kind is formed integrally with a bottom member 1 in which a drainage groove is formed by bending a steel plate, and a bottom member 1 formed by bending a steel plate. A drain pipe was used which was attached to the top of the tank and assembled with the upper lid body 2. The upper lid body 2 is provided with a plurality of intake openings 3 arranged in a row at intervals, and adjacent intake openings 3,
The ribs 4 interposed between the ribs 3 had to be made large in order to maintain strength.

(Problems to be Solved by the Invention) However, in such conventional drainage devices, the upper cover body 2 is integrally formed by bending a steel plate.For this reason, the thickness of the steel plate is limited in manufacturing, and the required strength cannot be achieved. I can't do it,
It had the disadvantage that it could be damaged by a collision if a car ran over it.

In addition, in the conventional upper lid body 2, the swallowing opening 3 is
The problem is that the number and size of drain pipes are limited, the sediment blockage rate is high, the amount of water collected decreases with long-term use, and the upper limit of the opening ratio is low, which increases the required length of the drain pipe and increases costs. There was a point.

Furthermore, since each bent and welded member is subject to large distortion when galvanized for rust prevention, one bottom member is required for each set.
The distortion of the upper lid body 2 had to be adjusted.

In view of the above-mentioned conventional drawbacks, the present invention makes the top cover body made of cast iron, so that the thickness is not limited and the required strength can be provided, so that it will not be damaged even if a car runs over it. By increasing the number and size of the intake ports, the intake ports will not be blocked by dirt even after long-term use.
It is an object of the present invention to provide a road drainage device that can reduce the cost by increasing the opening ratio and reducing the required length of the drainage pipe.

(Means for Solving the Problems) In order to achieve the above object, the gist of the present invention is to provide a bottom member constituting a drainage ditch, and a plurality of cast iron divided bodies disposed on the top of the bottom member. each of the upper lid bodies is provided with a plurality of intake ports arranged in a plurality of rows for introducing waste water into the bottom member, and the area of each intake port is equal to the area of the adjacent intake ports. Each intake opening is set larger than the area of the intervening vertical rib, and the upper lid body is removable from the bottom member, and the intake opening is formed on the inner wall surface of at least a part of the intake opening. A road drainage device is characterized by having a slope that spreads out in the back.

<Function> In the present invention, since the upper lid body disposed on the upper part of the bottom member constituting the drain channel is formed by connecting a plurality of divided bodies made of cast iron,
The upper lid body is easy to handle, and each upper lid body is provided with a plurality of intake ports arranged in a plurality of rows for introducing wastewater into the bottom member, and the area of each intake port is equal to the area of each adjacent intake port. Since the area is set larger than the area of the vertical ribs interposed in the swallow opening, the opening ratio of the swallow opening is improved, and the top lid and bottom member are removable, making it convenient to replace the top lid. Since the inner wall surface of at least a portion of the intake opening is sloped to make the intake opening wider and wider, the drainage can be smoothly introduced into the drain groove. Furthermore, since the required length of the drainage pipe is reduced, maintenance efforts after opening can be reduced.
