Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to a concrete cover for a side gutter.

(Prior Art) Conventionally, a concrete cover is usually placed on a drainage ditch formed at the edge of a road, allowing people, bicycles, and cars to pass over it. In addition, in order to drain the rain that falls on the road into the groove when it rains, there is a drainage notch on both sides or one side, but it is very small. In addition, some have multiple holes on the surface for drainage, but the holes are long holes and are placed in the span direction due to the structure of the concrete lid, so it is difficult to prevent rain from flowing from the direction of the road. The drainage capacity is really small.

Therefore, if you expect a large drainage capacity,
Grating is used for the drain cover.

However, on narrow roads, pedestrians walk on concrete covers or gratings to avoid cars, and women in particular wear high-heeled shoes, making it extremely difficult to avoid holes and openings. There is also the problem that the heel of the shoe gets stuck in the hole or opening, damaging the shoe and sometimes causing a foot injury.

Moreover, in the case of grating, the galvanized color is aesthetically undesirable compared to the surrounding concrete color, and the inside of the groove is visible when passing by. Another drawback was that the odor inside the ditch wafted directly into the air, making it undesirable.

(Problems to be solved by the invention) Therefore, this invention was devised to eliminate the above-mentioned drawbacks, and has excellent drainage function.
Moreover, the present invention provides a concrete cover for a side gutter that is not difficult to walk on and is robust.

[Structure of the idea]

(Means for Solving the Problems) Hereinafter, an embodiment of this invention will be described with reference to the drawings. In a concrete cover for a side gutter, a metal lattice-like frame 2 is arranged at the bottom of the cover and integrated. A lid body 1 is provided in the lid body 1, and a long hole 3 parallel to the longitudinal direction of the lid body 1 is bored, and the strip material 2a (bearing bar) of the lattice-like frame body 2 is exposed from the long hole 3. It is composed of the following.

Note that the metal lattice-like frame 2 refers to a grating, and is composed of a twist bar 2a orthogonal to a strip 2a with bulging upper and lower ends.
may be one in which the surface of the lid body or the surface of the lid body 1 and the elongated hole 3 are covered and filled with a water-permeable substance 4 (FIGS. 3 to 5);
As shown in the figure, the joint surface X between the water-permeable material 4 on the surface of the lid 1 and the concrete 1a may be inclined downward toward the elongated hole 3 to improve water drainage.

Further, the length of the elongated hole 3 may be close to the longitudinal width of the lid body (see Figure 1), or approximately half that width (see Fig. 6); is 2
It may be formed by arranging pieces in a straight line,
Furthermore, the drainage notch 5 may be provided on only one side of the lid 1, or may be formed on both sides.

(Function) Next, when using this invention, when placing the concrete cover for side ditches of this invention in a trench, it is necessary to use receiving frames with an L-shaped cross section formed facing each other on both sides of the trench. At least both ends of the metal lattice-like frame 2 are placed thereon one after another.

[Effect of idea]

According to this idea, the elongated holes are provided parallel to the longitudinal direction of the lid (perpendicular to the span direction), allowing for good drainage of rainwater flowing from the road. The metal lattice frame exists as a strength member and is robust, and when the surface and slots are filled with water-permeable material, it has good permeability, and even when the slots are left open. , the direction perpendicular to the span, rather than the conventional span direction, improves traffic.

Furthermore, since the strips of the lattice-shaped frame fit into the long holes, it is possible to prevent pebbles from falling into the groove, and since the metal lattice-shaped frame is placed inside the concrete, it improves the appearance. It is inconspicuous, dirt in the grooves is difficult to see, and odors in the grooves are prevented from dispersing to some extent, which is extremely beneficial.
