MANHOLE LID TO BASE CONNECTION
A manhole assembly including a base, riser, and cap. The base having an upper surface forming a bench, a bottom surface, and a radially outward surface with penetrations there through; a radial spigot in the radially outward upper edge of the base. A riser comprised of a corrosive-resistant polymer pipe having a bottom surface in contact with, supported by, and sealed to the radial spigot. The cap having a radial spigot in the radially outward bottom edge of the cap resting upon an upper edge of the riser. The radially outward surface of the cap and base are aligned with the radially outward surface of the riser. Also disclosed is a lifting connector extending from the manhole cap past the riser to the manhole base; and the lifting connector transferring lifting force in tension from the manhole cap to the manhole base to the riser.
