  • Installation precautions of composite resin manhole cover

    With the continuous development of technology, the composite manhole cover has been rapidly developed as a common material for municipal and construction, and the composite resin manhole cover produced by new composite materials has become a rookie. Here are some precautions for the installation of composite manhole covers: 1. Before installation, the foundation of the manhole cover must be neat and firm, and the inner diameter and length and width of the manhole cover must be determined. Second, install on the cement pavement
