Manhole Frame

A manhole frame is a structural component used in the construction of manholes. It is typically made of cast iron or concrete and is designed to provide support and stability to the manhole cover and the surrounding structure.

The manhole frame consists of two main parts: the frame and the cover. The frame is the outer structure that is embedded in the ground or pavement, while the cover is the removable lid that provides access to the manhole.

The frame is usually cylindrical in shape and has a raised lip or flange around its perimeter. This lip helps to secure the manhole cover in place and prevent it from shifting or being accidentally removed. The frame also has openings or slots where lifting tools can be inserted to lift and remove the cover.

Manhole frames are typically designed to withstand heavy loads and provide a secure and durable access point to underground utility systems, such as sewer lines, storm drains, or telecommunications cables. They are often found in urban areas, roadways, and industrial sites.

It is important to note that manhole frames and covers vary in size and design depending on the specific application and local regulations. They may also be customized to accommodate specific requirements, such as load ratings, traffic conditions, or environmental factors.

Overall, manhole frames play a crucial role in providing safe and convenient access to underground infrastructure for maintenance, inspection, and repair purposes.
