    Abstract: Pipes having dense, watertight concrete walls are produced by vibrating a rotating mould suspended on a roller shaft as the mold is being filled, and continuing its rotation without vibration for a short time after the mold is filled. Vibration is attained by ridges or fingers which can be made effective, or not, to vibrate the mold as it is rotating. In one form, fingers on a roller shaft are slidable between ineffective positions and positions where they serially engage a smooth running surface on the mold. In other forms, a mold is movable from a position where it is supported by engagement of a ridged running surface on either the roller shaft or the mold with a cylindrical surface on the other to a position where the cylindrical surface on the mold runs on the roller shaft or on an auxiliary sleeve without vibration.

    Abstract translation: 具有密实的水密混凝土墙壁的管道是通过在模具被填充时振动悬挂在辊轴上的旋转模具而产生的,并且在模具填充之后短时间内继续旋转而不振动。 振动是通过脊或手指获得的,这些脊或手指可以有效地使模具在旋转时振动。 在一种形式中,辊轴上的指状物可在无效位置和与模具上的平滑运行表面串联接合的位置之间滑动。 在其它形式中,模具可以从其被支撑的位置移动,该位置通过辊轴或模具上的脊状运行表面与圆柱形表面之间的接合而被移动到模具上的圆柱形表面在其上运行的位置 滚轴或辅助套筒无振动。
