    摘要： A curb forming machine for use by a single operator to form curved curbing includes a single rotatable curb-forming roller, a handle assembly for pulling and maneuvering the roller, and a motor for rotating the roller. The roller includes a generally cylindrical body, a neck at one end of the body, and a shaping surface, all of which are coaxial. The motor rotates the roller so that the lower periphery of the roller moves toward the direction of pulling to shape and smooth wet concrete into curbing. An overflow guard prevents wet concrete from flowing over the roller onto the finished curb, and an alignment device extends outwardly from the roller to contact a form member. A curb forming method includes pulling and steering such a roller around a curved form, including around tight curves in the form.

    摘要： A method for levelling and smoothing concrete when concreting large areas. According to the method a machine which is so constructed that it floats lightly even on highly fluid concrete mass and thus normally exerts a very low surface pressure against the substratum, is caused to move over the surface of the concrete while smoothing and levelling the same as a result of rolling motion between the surface and a belt of the machine in contact therewith. The smoothing or levelling effect of the belt can be amplified by vibrating a plate supporting the belt. The concrete may also be subjected to vacuum treatment at the same time as levelling or smoothing the concrete. The invention also relates to a machine for carrying out the method.

    摘要： The present invention levels freshly poured concrete, internally vibrates a linear segment of that concrete and then moves forward and remixes a surcharged concrete layer to yield a more uniformly dense mass of concrete. The apparatus includes a bridge spanning the width of a plastic concrete surface and is suppported above and maintained substantially parallel to the plastic concrete surface. A small diameter auger is coupled to a carriage suspended beneath the bridge and is laterally translatable back and forth along the length of the bridge within the linear segment of concrete to level the irregular concrete surface to form a flat intermediate surface. An internal vibrator module is laterally translatable along the bridge for internally vibrating the plastic concrete to densify material within the linear segment into a surcharge layer. A large diameter auger is coupled to the carriage behind the small diameter auger to engage the concrete at a level below the intermediate surface and displace the surcharge layer forward and out of the linear segment as the bridge is translated forward with respect to the linear segment.
