In the Hetai Road renovation project, load-bearing manhole covers have been installed to cover the wellheads of underground facilities such as sewers, inspection wells, and valve wells. These manhole covers not only have a protective function, providing solid protection for underground facilities and shielding them from external interference, but also effectively ensure safety and facilitate subsequent maintenance work.
For this project, composite manhole covers of different specifications have been specifically ordered: 50 sets of 350mm small composite manhole covers with a load-bearing capacity of 25T; 100 sets of 500mm medium-sized composite manhole covers, also with a load-bearing capacity of 25T; and 70 sets of 700mm large composite manhole covers, which also have a load-bearing capacity of 25T. These manhole covers will accurately fit the wellheads of various underground facilities along Hetai Road, providing strong support for the stable operation of industrial facilities and the safe and smooth flow of the road.
