In the dynamic landscape of urban development, the design and construction of infrastructure play a critical role in promoting safety, functionality, and aesthetics. Among various infrastructure elements, manholes serve an essential purpose, providing access to underground utilities such as sewage, drainage, and electrical systems. Traditionally, manholes have been round due to the simplicity of their structural integrity; however, the push for innovative designs has led to the evolution of round to square manhole conversions, offering several advantages.
A manhole cover is a removable lid over an opening to a man-made hole large enough for a person to pass through i.e. a manhole. For security reasons a cover keeps unauthorised people out and for safety reasons it prevents anyone (or anything) from falling in. These types of covers are typically used to safely and securely restrict entry to foul and surface water drainage systems, and other underground chambers, that require worker access for maintenance purposes. They are often made from cast iron, ductile iron, galvanised steel, concrete or even a combination of several of the above.
