Abstract:
1. A manhole for connecting fluid flow between and for providing access to an inlet pipe and an outlet pipe angularly oriented to one another in a utility system, including a sewage or storm water utility system, the manhole comprising an upright housing defining a manhole interior, the housing being generally in the form of a circular sector defined by adjacent first and second essentially planar upstanding outer sidewalls extending generally as respective radii of the circular sector from adjacent a common center to respective outer distal wall ends, the sidewalls being angularly oriented to one another at substantially the same angle as between the inlet and outlet pipes, and a curved upstanding outer side wall extending arcuately between the outer distal wall ends of the first and second planar sidewalls, first and second openings formed respectively through the first and second planar sidewalls into the manhole interior for receiving respective ends of the inlet and outlet pipes, and a sector-shaped base section within the manhole interior defining a curvilinear fluid flow trough between the first and second openings for conveying fluid flow from the inlet pipe to the outlet pipe.
