Benefits of technology

The method enables the production of precast concrete meter pits with a robust support ledge for covers, reducing labor and safety risks while ensuring efficient and uniform construction, suitable for various climate conditions.

Problems solved by technology

The concrete-sectioned meter pits are assembled in segments using a tongue-and-groove connection which is labor intensive and also poses a safety risk when assembling the meter pits by hand which must be transported and assembled on site.
In addition, packerhead assemblies have been devised for slip forming concrete pipe including a trowel assembly at one end of the packerhead assembly to form an outwardly directed, offset end but for several reasons are not practical for use as a meter pit.

Embodiment Construction

[0018]There is illustrated in FIG. 1a form of meter pit 10 for housing a water meter, not shown, beneath the ground. The meter pit 10 is comprised of an elongated precast concrete pipe 12 of cylindrical configuration and which is of uniform thickness throughout except for an upper end which terminates in a beveled edge 13 which defines a support ledge projecting radially inwardly from the upper terminal end 14. Dual spaced notches 15 are formed in an opposite lower edge 17 for receiving water lines, not shown. Although a single notch is illustrated, there is a diametrically opposed notch and which together receive the water lines for water flow into and out of the water meter which is housed inside of the pit.

[0019]The terminal end 14 of the beveled edge 13 is substantially flat and squared to the longitudinal axis of the pipe so as to form a ledge or seat for supporting a generally bell-shaped cover 16. The cover 16 is of standard construction including spaced projections or posts ...

Abstract

A precast concrete meter pit consisting of an elongated hollow pipe having a beveled support ledge at one end and notches at the opposite end is fabricated by utilizing a slip form packerhead apparatus in which the beveled support ledge is formed by a radially inwardly inclined trowel edge bearing against a pallet member which is caused to vibrate when concrete is injected into the slip form apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of U.S. Ser. No. 11 / 048,544, filed 31 Jan. 2005, entitled “PRECAST CONCRETE METER PIT AND METHOD AND APPARATUS FOR MAKING SAME,” which application is incorporated by reference herein.BACKGROUND AND FIELD[0002]This method relates to meter pits; and more particularly relates to a novel and improved method of fabricating a precast concrete meter pit.[0003]Meter pits for water meters are customarily fabricated out of plastic or stacked concrete in the form of a cylindrical pipe. The plastic meter pits typically sell at a higher price than concrete pits and tend to deform under certain conditions. The concrete-sectioned meter pits are assembled in segments using a tongue-and-groove connection which is labor intensive and also poses a safety risk when assembling the meter pits by hand which must be transported and assembled on site. The pipes are then buried in the ground, typically below frost level, and have...
