Abstract: A method for forming large concrete pipes of no-slump concrete and in which the inner and outer concrete molds are horizontally disposed and the annular space therebetween is filled with no-slump concrete through a longitudinal opening in the outer mold. The inner mold is withdrawn axially in generally horizontal direction from the outer mold immediately after the pour has been made. The outer mold together with the wet pipe therein can then be immediately swung to a vertical position so the pipe on its end pallet can set on support legs and the outer mold is then immediately axially stripped upwardly from the finished pipe.
