摘要： Apparatus for slip-forming a pipe or drainage trench including a leading cutter which is attached to the front of a prime mover for digging a trench. A following cutter is also attached to the front of the prime mover, but behind the leading cutter to thereby level off the surface of the ground along the top of the trench. A rigid concrete shaping apparatus including a portion overlying the trench also includes a rigid tubular portion which is disposed within the trench. A roll of flexible plastic material is connected to the apparatus and this plastic material is sealingly connected at one end thereof to a source of air pressure which causes the plastic to inflate to a tubular shape. This plastic is thereby maintained in an inflated condition and extends along the length of the trench to a point inside of the tubular portion of the concrete shaping apparatus, at which point the plastic is pinched by rollers to thereby maintain the pressure within the inflated portion of the flexible tube. One end of the rolled portion of the roll of plastic extends down through one end of the tubular portion of the concrete shaping apparatus, through the rollers and out through the other end of the tubular portion of the shaping apparatus to connect to the source of air pressure. The prime mover moves slowly ahead as concrete is continually supplied to a hopper on the concrete shaping apparatus, which apparatus fills the trench with concrete in a plastic state and forms a concrete structure with an open tubular center. The plastic material unrolls and inflates inside of the hollow concrete structure formed to thereby prevent the concrete on the top of the hollow open tubular center from collapsing. Once the concrete has cured and hardened, the pressure in the plastic tube can be relieved and the tube removed. The formed pipe or drainage structure is then complete.

摘要： 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.
