Pre Cast Manhole are an integral component of any modern sewer system. A properly designed and installed precast concrete manhole system provides superior watertight performance compared with competing methods and materials. A typical precast concrete manhole could be installed 500 feet deep and more because lateral forces act equally around the periphery, which places the section in pure compression- the ideal state for concrete. Manufactured in the controlled environment of a plant, these vital infrastructure components will stand strong for decades of trouble-free service.
Pre Cast Manhole strengthens with time, while other materials can deteriorate, experience creep and stress relaxation, lose strength and/or deflect over time. The load-carrying capacity of precast concrete manhole is derived from its own structural qualities and does not rely on the strength or quality of the surrounding backfill materials. Studies have shown that precast manhole is of M-40 Grade and having AA Class Loading Capacity
Precast Circular Manholes are used in sanitary sewer and storm drain systems for access, observation and junctions. They are good choice for:
