Manufacturing Sewer Maintenance Shafts
Abstract The present invention relates broadly to a sewer maintenance shaft 8 including a base moulding 10 comprising a perimeter wall 12 connected to a floor 14 and part of a fluid outlet coupling 16. The base moulding 10 includes an inlet aperture 18 designed to accommodate an inlet spigot (not shown) of a predetermined size. The inlet aperture 18 is machined in the perimeter wall 12 of the base moulding 10 at a location and orientation depending on: 1. a predetermined angular deflection of the inlet spigot relative to the fluid outlet coupling 16; 2. a grade offset of the inlet spigot relative to a horizontal reference derived from the floor 14 of the base moulding 10; 3. a height of the inlet spigot relative to the horizontal reference. en w C 0 V., U.
