ABSTRACT:
A bell and spigot joint of reinforced concrete manhole risers, or pipes, or abutting joints therein are improved by precasting the same, free or pre-cast grooves in the exterior faces intended for seating sealing rings. After pre-casting and curing in the kiln, the hardened, cured surfaces are machined to form a sealing ring groove proximate the ends thereof, for example around the spigot of a bell and spigot joint. The inside of the bell is also machined to hone the same to a smooth finish. The grooving apparatus is precisely centered on the axis of the member to produce a groove of uniform radius relative thereto.
