Manhole cover bracket can be said to be a very important component of stainless steel manhole cover . Its upper end has the same diameter. It plays an important role in reducing the impact force of the manhole cover on the bracket and the noise generated by the collision, and preventing the destructive effects such as the bounce between the manhole cover and the bracket.
Each material has its own characteristics, so it will be placed in the right place and play a big role. A mixture of steel wire and rubber is selected as the support material under the manhole cover. First, rubber has comprehensive properties such as corrosion resistance, oil resistance, fire resistance, oxidation resistance, high density, etc., and has a protective effect on hard objects.
Fill the rubber with steel wire to make rubber and steel wire a mixed material. Used to increase the density of rubber mounts. The use of steel wire and rubber as shock absorbers has the functions of anti-wear, anti-penetration, etc., which reduces the damage coefficient and the noise decibel.
In the environment of use, it is not easy to walk because it can withstand wider temperature differences. Buffer the collision between the manhole cover and the bracket to effectively protect the manhole cover.
Because the label is not clear enough, if there is a problem, if the direct responsible person is not contacted in time, it may cause serious consequences. The manhole cover currently laid on the highway has been renovated. Firstly, the function and responsibility unit of the manhole cover shall be marked with detailed text identification, and then the function of the manhole cover shall be identified by the decorative theme and external model. For example, in Japanese manhole covers, some shapes have obvious marking effects. Fire hydrant damaged manhole covers are mostly rectangular, with fire fighting characters and decorations. Even at relatively long distances, they can be easily distinguished in shape from other functional manhole covers and have significant effects.
In addition, the pattern on the stainless steel manhole cover is not only a decoration, but also a language with a certain recognition function. Through decorative patterns, pedestrians can learn about the city's special folk culture, tourist attractions, direction coordinates, underground functions and other information.
