Manhole cover, a public facility that can be seen everywhere in the city. Perhaps most people have no special impression of it, except for its gray-black and rustic appearance.
However, this simple manhole cover is as beautiful as a work of art in Japan, which makes people have to accept the level of Japanese art.
In Japan, the art manhole cover has become a distinctive city card. Manhole covers are rich in patterns, with guiding functions and various commemorative meanings. The manhole cover is decorated with colorful patterns, telling you what is the most famous and interesting city, or the history of the city. Thinking about it carefully, in a small and fresh Japan, it seems that even ordinary things can become unique and fresh.
The rise of art manhole covers
In 1985, a Japanese architect created the Japanese tradition of "using beautiful patterns on manhole covers" to make the surface of manhole covers more visual and eye-catching, attracting people's attention to expensive urban sewage treatment systems. It was this brilliant idea that prompted him to encourage local governments to design covers with local characteristics. Gradually, manhole covers with local characteristics became popular throughout Japan.
An ordinary manhole cover, the Japanese who pursued the ultimate details, not only gave it a beautiful appearance, but also gave it a variety of functions, which can be described as unique and original.
Solve the problem of manhole cover noise
In many countries, manhole covers are a major noise source in cities. As the manhole cover does not fit well with the road surface, unpleasant noises will be emitted when the vehicle passes the manhole cover. Japanese manhole cover manufacturers have made improvements, changing the original cylindrical shape to a cone shape, and changing the vertical plane along the thickness direction to an inclined plane with a certain inclination angle, which enhances the consistency with the road surface and successfully solves the noise problem.
Japanese manhole covers with different shapes and patterns have different uses.
Art manhole covers are decorated with different patterns, such as city flowers, regional flowers and machine flowers. Once repairs are needed, you can immediately determine the jurisdiction of which administrative area; the words "private" or surname on the manhole cover indicate that this is a personally owned sewer; most Japanese fire hydrant manhole covers are square with cute printed on them Cartoon pattern fireman.
It is a signpost indicating the direction.
In modern metropolises such as Tokyo, manhole covers can also be used as "road signs". The place name is written on the square diamond of the manhole cover, which can indicate the direction for lost pedestrians. Japan is a country with frequent natural disasters, and there are "emergency shelters" near residential areas. In addition to using arrows to indicate directions, some shelters are also painted. The yellow arrow indicates within 200 meters of the shelter, and the red arrow within 100 meters.
