  Ductile iron manhole covers are used to cover roads or deep well dwellings to prevent people or objects from falling. According to the material, it can be divided into metal ductile iron manhole cover, high-strength fiber cement concrete ductile iron manhole cover, resin ductile iron manhole cover, etc. General. It can be used in Greenbelt, sidewalk, motorway, wharf, Hutong, etc.

  井盖文化自20世纪60年代以来一直很流行。美国、法国、德国、波兰、芬兰、韩国、日本、挪威、巴西、加拿大等一些城市都有自己独特的井盖文化。国外许多历史文化名城都把井盖文化提升到了城市名片的高度。近年来,我国部分地区也出现了球墨铸铁井盖文化。良好的球墨铸铁井盖文化不仅可以美化城市环境,而且可以减少球墨铸铁井盖事故的发生。

  1。 为什么下水道的球墨铸铁井盖设计成圆形?

  1。 Why is the ductile iron manhole cover of the central sewer designed to be round?

  A:方形/长方形的球墨铸铁井盖更容易掉下来。

  A: Square / rectangular ductile iron manhole covers are easier to fall off.

  圆度的优点:

  Advantages of roundness:

  一是原力是好的;

  First, the force is good;

  二是:美观;

  Second, it is beautiful;

  三是:成本较低,相同直径长度的方形用木材较多
