In apparatus for making a precast concrete meter pipe wherein a packerhead assembly includes a trowel assembly, a rollerhead assembly and a jacket in outer spaced concentric relation to said packerhead assembly, the improvement comprising:
- a slip ring positioned within said jacket;
- said trowel assembly being of generally cylindrical configuration and terminating in a radially inwardly and downwardly inclined lower edge;
- and
- an annular pallet positioned beneath said trowel assembly having a riser circumscribing an inner annular edge thereof and extending upwardly within said trowel assembly.
In apparatus for making a dual piece precast concrete meter pipe wherein a packerhead assembly includes a trowel assembly and a rollerhead assembly and a jacket in outer spaced concentric relation to said packerhead assembly, the improvement comprising:
- a slip ring positioned within said jacket;
- said trowel having a radially inwardly and downwardly inclined lower edge and extending along an outer circumference of a pallet;
- and
- said pallet is of annular configuration having a riser at an inner edge thereof engaging said trowel lower edge.
A meter pit comprising a plurality of precast concrete hollow elongated cylindrical wall sections in end-to-end relation to one another, a first of said sections having a circular support ledge, said circular support ledge projecting radially inwardly from one end of said first section and a second of said sections including circumferentially spaced notches at one end.
