ABSTRACT:
This invention pertains to a method and machine for slip forming concrete wall structures such as median barrier walls for highways. The slip form comprises a pair of opposite side walls each of which has a skirt member retractable and extensible relative to the lower portion thereof. A top wall separate from the side walls is mounted on the machine frame between the upper portions of the side walls, and each side wall and associated skirt member is movable as a unit relative to the top wall and each skirt member is independently movable relative to an associated side wall. The side walls are adjustably supported on the machine frame for adjustment laterally of the machine frame to accommodate top walls of varying widths and the top wall is verticaly adjustable relative to the machine frame independently of the side walls. Power means provide for a controlled relative movement of the side walls, skirt members and top wall and the relative arrangement of the side walls and top wall is such that a glare shield can be formed over any selected section of the barrier wall without interrupting the continuous advance of the machine in the forming of the barrier wall with linear and reversely curved sections.
