ABSTRACT:
A pipe mold for vertically cast concrete pipe includes a cylindrical outer mold case, a cylindrical core spaced inside the mold case, and a pipe-reinforcing cylinder between the core and the case. A system for casting concrete in the pipe mold includes a flat facing ring above the annular space between the mold case and the cylinder. A chute assembly mounted concentrically above the pipe mold includes several radially extending and spaced apart pouring chutes extending downwardly from the center of the chute assembly to corresponding circumferentially spaced apart openings in the facing ring. The pouring chutes channel the flow of concrete into the openings in the facing ring to fill the pipe mold to the bottom surface of the facing ring, which forms a flat annular end section at the desired elevation on the pipe. The facing ring eliminates the need for hand finishing and measuring which is common in the prior art manufacture of vertically cast concrete pipe. A concrete pipe with a beveled end section is formed by mounting the facing ring in an angular plane above the pipe mold. As the concrete is channeled into the openings of the beveled facing ring, gates in the pouring chutes are sequentially closed to progressively block the rise of concrete from the low side to the high side of the facing ring until the pipe mold is filled to the bottom of the ring which automatically forms a flat, beveled annular end section at the desired elevation on the pipe.
