      Specification for ductile iron rain grate for municipal roads

      在**道路、住宅小区等场所经常会看到雨水篦子，不同的使用场所里，它的使用效果也都是非常好的，它的耐腐蚀性能是非常强的，不需要特别的保养和维护也不需要，**道路球墨铸铁雨水篦子规格，它还有着非常高的强度和韧性，它的强度远远**过铸铁，可以在一些比较大的场所中进行使用。

  Rainwater grate is often seen in municipal roads, residential areas and other places. In different places of use, its use effect is also very good. Its corrosion resistance is very strong, and there is no need for special maintenance. The specification of nodular cast iron rainwater grate for municipal roads is very high in strength and toughness. Its strength is far higher than that of cast iron, and it can be used in some large places.

       球墨铸铁井圈井盖采用机械接口配件进行连接，采用钢制双套进行连接、接口形式为油麻膨胀水泥接口，在安装的过程中会出现一些问题。 **道路球墨铸铁雨水篦子规格，在安装铸铁雨水篦子的时候，一定要根据具体的施工环境*不同的施工策略和方法。比如说水沟的两边支撑必须是平整坚固的，在我们进行安装的时候，支撑框的锚固片必须是深深的埋入地下的水泥层中，一般情况下我们建议选择的标准尺寸进行设计和施工，保符合国家的相关规范。 

  Nodular cast iron well ring and well cover are connected by mechanical interface fittings and steel double sets. The interface form is oil hemp expansion cement interface. Some problems will occur during installation. Specifications of ductile iron rain grate for municipal roads. When installing cast iron rain grate, different construction strategies and methods must be specified according to the specific construction environment. For example, the supports on both sides of the ditch must be flat and firm. When we install, the anchor plate of the support frame must be deeply embedded in the underground cement layer. Generally, we recommend to select the standard size for design and construction to ensure that it meets the relevant national specifications.
