Maintenance Hole System
Definition - What does Maintenance Hole System mean?
A maintenance hole system is the structure that makes up a manhole and any related parts. It is used for access to underground infrastructure, such as sewers. Trenchless construction workers often enter maintenance hole systems during the installation and rehabilitation of underground pipes.
Trenchlesspedia explains Maintenance Hole System
A maintenance hole, also known as a manhole, is an entryway through which maintenance personnel pass when working underground. Manholes have not changed in the past 50 years, but some manufacturers are viewing them as systems and making improvements to the traditional structure.
One of the hazards that affect maintenance holes are inflow and infiltration. Due to the breaking and crumbling of the rings around a manhole, some have required chronic rehabilitation. New designs to maintenance hole systems can increase their lifespan and even increase storm and sewer capacities. Any improvements to maintenance holes are a benefit to workers in trenchless construction.
