Petropedia explains Manhole

A Manhole is a vertical access cylinder from the ground surface to the underground utilities or sewers. Manholes are present usually at the junctions and they allow inspection, cleaning, repairs and connections. It is also known by various names such as utility hole, inspection chamber, access chamber and maintenance hole. However the term Manhole is most commonly used to refer to these openings. Each Manhole has a cover known as a Manhole cover which is a removable plate that forms a lid over the opening of the Manhole. The Manhole covers prevent anything or anyone from accidentally falling into Manholes and also prevent them from letting any unauthorized material and person enter.
