Decorative sewer manhole covers
In the late 1850s, in order to increase the anti-skid effect of the road surface, engineers in large cities such as Tokyo improved the surface texture of the manhole cover and added some concave-convex pattern designs. Because in the rainy season, accidents of motorcycles and bicycles slipping on the manhole cover frequently occur, and increasing the surface friction not only solves the problem well, but also makes it more beautiful, so these engineers took such manhole covers to other small cities and In some small towns, manhole covers with "Tokyo Design" or "NAGOYA Design" can still be seen in some small towns. However, the fine tradition of "using beautiful patterns on manhole covers" was created in the 1880s by a Japanese named Yasutake Kameda. Yasutake Kameda was an architect at the National Architecture Office of Japan at the time. At that time, Japan’s urban sewer system was similar to the current situation in China. It was expensive but inconspicuous. In order to make this huge “government project” more widely known and popular, Yasutake Kameda thought of “making the surface of the manhole cover more attractive. "Visualization, more eye-catching" idea, therefore, he encourages cities, towns and rural areas to develop their own manhole cover designs with local characteristics. Gradually, individual manhole covers became popular throughout Japan.
The most widely used internationally are mainly developed countries such as Japan, Australia, Europe and the United States
The manhole cover is the city card of Japan. It started with solving practical details, and became an art because of its exquisite workmanship, and finally became a special culture that was continuously popularized. In almost every city in Japan, you can see colorful sewer manhole covers, which are printed with animals, landscapes, historical stories or urban characteristics, which are very design. Not only have several manhole cover museums been established. A semi-official "Manhole Cover Association" was also established to protect and research manhole covers throughout Japan. During the rainy season, accidents of motorcycles and bicycles slipping on the manhole cover frequently occur. The engineer improved the surface texture of the manhole cover by adding some concave-convex pattern design, which is not only non-slip but also beautiful.
Europe and America
In European and American cities, the streets and alleys of "art manhole covers" can be seen everywhere. They appear in front of people in the form of road signs, maps, landmarks, and artistic patterns. While they have some of the characteristics of Japanese manhole covers, they have a variety of materials and more patterns. Continued the artistic style of European and American characteristics. And in terms of materials and craftsmanship, European and American "art manhole covers" are even more diverse. Materials such as cast copper, iron, and epoxy resin are widely used, and craftsmanship such as flat carving and relief carving are also widely used. Especially the relief sculpture, the craftsmanship is comparable to a relief artwork.
