A rectangular manhole in architecture serves as an access point to underground utilities like sewage systems, drainage networks, and electrical conduits. Its shape offers practical advantages, such as ease of construction and integration with linear infrastructure, like walls and curbs.
Rectangular manholes provide ample space for workers to enter and maneuver during maintenance or inspections. Additionally, they can accommodate larger equipment and materials, making them ideal for complex utility networks.
However, unlike circular manholes, rectangular ones require reinforced corners to handle structural loads and prevent cracking over time. Their design often balances functionality, durability, and accessibility in urban and industrial settings.

A rectangular manhole in construction consists of several key components designed for structural stability and accessibility. The base is typically made of reinforced concrete, providing a solid foundation to support loads and prevent settling.
Side walls, also constructed from reinforced concrete or brick masonry, rise vertically from the base, ensuring durability and resisting soil pressure. Steps or ladders are fixed to one side, offering safe access for maintenance personnel.
The top section includes a cover slab with an opening for a cast iron or concrete lid, which ensures secure closure while allowing easy inspection access. Proper drainage provisions, like benching and channels, guide wastewater flow efficiently, preventing sediment buildup.
Waterproofing measures and joints are carefully sealed to avoid leakage, ensuring the manhole’s longevity and structural integrity.
