The lid 2 exposes its outer surface to the road surface,
The outer surface is paved 4 in the same manner as the pavement on the road surface, and a cover is opened and closed from the ground so that cable wiring or maintenance and inspection can be performed.

As shown in FIG. 1, a synthetic resin sheet 5 having a slippery surface is continuously adhered to the left and right inner concrete surfaces and the inner bottom concrete surface of the concrete U-shaped groove 1. Preferably, the synthetic resin sheet 5 is made of the concrete lid 2 as shown in FIGS.
It is also affixed to the inner concrete surface.

The U-shaped groove 1 and the lid 2 have a fitting structure. As this fitting structure, a step 6 extending longitudinally is formed inside the upper ends of the right and left side walls of the U-shaped groove 1. Part 6
A structure is adopted in which the lid 2 is dropped and fitted inside.

As shown in FIG. 3, the synthetic resin sheet 5 adhered to the inner concrete surface of the concrete lid 2 has right and left edges which are the closing surfaces of the concrete U-shaped groove 1 and the concrete lid 2. (The upper surface of the step 6).

As shown in FIG. 5, the right and left upper ends of the slip synthetic resin sheet 5 adhered to the inner bottom concrete surface and the left and right inner concrete surfaces of the U-shaped groove 1 are connected to the inner concrete surface of the step 6 (closed surface). ), And the entire inner wall concrete surface of the U-shaped groove 1 is covered with one slip synthetic resin sheet 5, and another slip synthetic resin sheet 5 is attached to the inner cover concrete surface of the concrete lid 2. The left and right edges of the synthetic resin sheet 5 covering the inner surface of the lid 2 and the upper right and left edges of the synthetic resin sheet 5 covering the inner surface of the U-shaped groove 1 are closed surfaces (the inner surfaces of the step portions 6). To superimpose.

The synthetic resin sheet 5 interposed between the concrete U-shaped groove 1 and the closed surface of the concrete lid 2 ensures the close contact between the two at the closed surface and prevents the backlash. In addition, the elasticity reduces the impact when the cover 2 is opened and closed.

The lubricating synthetic resin sheet 5 is formed, for example, by vacuum forming, and has a plurality of regularly arranged projections 7 on its back surface and a plurality of bottomed holes 8 corresponding to the projections 7 on its inner surface. I do.

In other words, the bottomed hole 8 is vacuum-formed on the inner surface of the sheet 5, and at the same time, the projection 7 is vacuum-formed on the opposite back surface. As shown in FIGS. 4 and 7, the projections 7 bite into the concrete U-shaped groove 1 or the concrete surface layer of the lid 2, thereby strengthening the connection between the sheet 5 and the both 1 and 2.
Also, a number of bottomed holes 8 are formed in the inner wall surface defining the wiring cavity or drainage cavity 3.

The bottomed hole 8 can be used as an anchoring hole for attaching a hanger for cable wiring.
It also serves as a guide indicating the cable wiring position. The bottomed hole 8 can be filled with a rat-proofing agent, an antibacterial agent, or the like.

The present invention includes, as an embodiment thereof, a case in which an antibacterial agent is filled or applied to the slip synthetic resin sheet 5. As the above-mentioned antibacterial agents, there are phenol type and halogenated bisphenol type. Recently, attention has been focused on glass powder made of fused glass, which when applied to the overcoat of pottery (tableware), the frame of eyeglasses, and other parts, has a remarkable effect of suppressing the generation of fungi and other germs. Using this, an antibacterial agent such as glass powder is kneaded and applied to a resin coating such as a polyurethane resin coating on the surface of the above-mentioned lubricating synthetic resin sheet to form an antibacterial layer, or Add antibacterial effect by filling in the material.

In the above embodiment, the wiring groove or the drain groove composed of the U-shaped groove 1 and the lid 2 has been described. However, the present invention does not have the lid 2 and the whole is integrally molded into a rectangular tube or the like. The case where the slip synthetic resin sheet 5 is adhered to the drain groove or the wiring groove with the configuration described above is included.
