Definition - What does Manhole Rehabilitation mean?
Manhole rehabilitation is defined as the process of repairing, upgrading or replacing a manhole system. Manholes are the most important part of a sewer network as they are the access points for any kind of repair work to be carried out in the sewer network. Manholes need to be maintained and kept in good condition to carry out quick repairs, and to prevent injury to workers who use these manholes for going underground. Manholes typically consist of different components made of varied materials, and each of these are subject to their own set of deterioration and damage. Regular inspection and repair of these component parts will ensure a longer life of the manhole and lessen costs of replacement in case of failure.
Trenchlesspedia explains Manhole Rehabilitation
The different components of a manhole can be rehabilitated using different techniques such as grouting, paneling, mechanical repairs and cementing. One or more of these methods may have to be applied to carry out manhole rehabilitation. Before selecting a particular method to carry out a repair, it is essential to perform a thorough inspection that will give a clear picture of the extent of damage in the manhole. If leakages, missing parts, broken components or corrosive damages are detected, then these issues must be addressed before the manhole surface repair can take place.
