APPARATUS FOR PRESSING A CONCRETE PIPE IN AN UNDERLYING SOCKET BY CENTRIFUGAL FORCE |
摘要 |
In radially centrifugally molding sections of concrete pipe with a bell at one end, the concrete is poured downwardly into an upwardly extending mold which forms the outer surface of the pipe section. The lower end of the mold is shaped to form the bell end of the pipe section. The concrete is centrifugally forced outwardly against the inner surface of the mold and then is pressed outwardly by a series of rotatable rollers. A pressure wheel is located within the mold above the position of the rollers for limiting the upward movement of the concrete pressed outwardly against the mold and for increasing the concrete pressure acting downwardly toward the bell end of the concrete pipe section. |
