ABSTRACT:
A self-propelled slip form, closed at its top, front, and sides, but open at its rear and bottom, provides a pressure chamber having the cross-sectional shape of a wall or similar structure to be cast. Such slip form may be advanced continuously at a slow rate or in stages, but whichever it is, the advance is due solely to pressure exerted against the closed front of the slip form through the intermediacy of the deposited, unset concrete or the like. Such pressure can be utilized to pre-stress reinforcing material on a continuous basis as it is fed into the pressure chamber simultaneously with deposit of the concrete or the like.
