检查井钢模具采用组装的方式构成，具有良好的组装、拆模过程。该模具分为内膜和外模两部分，使用简单方便。因为该模具为质钢的，这种材质容易生锈，为了防止生锈在不用时涂抹润滑油。
Inspection well steel die is made up by assembling, which has a good assembly and demolition process. The die is divided into inner and outer parts, which is easy to use. Because the die is made of quality steel, this material is easy to rust. In order to prevent rust, lubricating oil is applied when not in use.
隔绝空气防止和氧气发生氧化，增加脱模的平滑性，同时也可以增加检查井钢模具的使用寿命。
Isolation of air prevents oxidation with oxygen, increases the smoothness of demoulding, and also increases the service life of steel mould for inspection wells.
