水泥井篦子模具材质

   铸铁井盖在马路上的应用是非常常见的，保证着我们的行驶安全，水泥井篦子模具今天就来跟大家讲讲关于铸铁井盖安装的注意点。

1．选用铸铁井盖的内径（或内长X宽）一定要大于等于预留井口尺寸，否则将大大影响承载力；

2．在安装时井座与混凝土地面结合面一定要贴实，不得有悬空的地方，否则在施工安装中会被压路机压坏和影响使用寿命；

3．在沥青路面上安装铸铁井盖时，一定要注意避免施工机械直接碾压井座，在路面施工时，应在路面预留比井座略大的孔，在沥青铺完后安置。不知道大家有没有注意过，近年来大街上丢井盖的案件越来越少了。这固然要归功于社会治安的持续进步，但另一方面，“井盖科技”的进步也不可小

Mold material of cement well grate

The application of cast iron well cover on the road is very common, which ensures our driving safety. Today, the cement well grate mold will tell you the points for attention about the installation of cast iron well cover.

1. The inner diameter (or inner length x width) of cast iron manhole cover must be greater than or equal to the reserved wellhead size, otherwise it will greatly affect the bearing capacity;

2. During the installation, the joint surface between the well base and the concrete ground must be close, and there shall be no hanging place, otherwise, it will be crushed by the roller and affect the service life during the construction and installation;

3. When installing the cast iron well cover on the asphalt pavement, it is necessary to avoid the construction machinery directly rolling the well base. During the pavement construction, the hole slightly larger than the well base shall be reserved on the pavement and placed after the asphalt pavement is completed. I don't know if you've noticed that in recent years, there have been fewer and fewer cases of lost manhole covers on the street. This is due to the continuous progress of social security, but on the other hand, the progress of "well cover technology" cannot be underestimated.
