Abstract: Cast-in-place concrete pipe reinforced with fibers and the method of making such reinforced cast-in-place concrete pipe is disclosed. The apparatus used in making such reinforced cast-in-place concrete pipe is described.

Abstract: A cementitious conduit is formed in situ in a ditch or the like by defining an elongated volume of annular cross-section within the ditch with the axis of elongation of the annular volume extending along the ditch and with one end of the annular volume closed and the other end thereof open. A solidifiable cementitious material is introduced into the annular volume at the closed end thereof and such cementitious material is continuously urged to move toward the open end thereof at a rate at least equal to a given rate. Simultaneously, the volume is moved along the ditch at such given rate with the closed end thereof preceding the open end thereof and circumferential frictional forces are applied to the cementitious material at the inner surface of such annular volume.
