Computerized concrete placement system comprised primarily of computer hardware and computer software which allows concrete to be placed over contoured sites
A wheeled strike-off apparatus (10) is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support (12) and a plow assembly (14). The wheeled support may have a front frame portion (212a) and a pair of front wheels (224) rotatably mounted at the front frame portion, and may have a rear frame portion (212b) and a pair of rear wheels (226) rotatably mounted at the rear frame portion. The plow assembly may be adjustably mounted to the front frame portion and may be vertically adjustable relative to the frame portion via an actuator (230). The plow assembly includes at least one plow member (218) for engaging and establishing the desired grade.

E01C 19/42 - Machines for imparting a smooth finish to freshly-laid paving courses other than by rolling, tamping, or vibrating
A subgrade preparation apparatus for preparing a subgrade surface for concrete to be placed thereon includes a base unit positionable on a support surface adjacent to a targeted subgrade area, an extendable boom extending from the base unit, and a subgrade head assembly adjustably mounted on the extendable boom. The subgrade head assembly includes a framework, a plow and a material moving device for moving material toward at least one side of the subgrade head assembly. The subgrade head assembly includes a plow end plate movably attached at an outer end of the plow and movable to a position where the plow end plate is generally vertical and forms an end portion of the plow to limit plowed material from flowing around the outer end of the plow as the subgrade head assembly is moved over and along the subgrade surface at the targeted subgrade area.
