Abstract
Slipform paver may include rheometers for measuring rheological parameters. The rheometers may include vane rheometers in a grout box of the slipform mold. The slipform paver may dynamically determining the rheological parameters of concrete and controlling a target vibrational frequency of vibrators based on the rheological parameters. The slipform paver may also use depth sensors, cameras, and/or electric vibrators for controlling the target vibration frequency.
Claims20
A paving machine comprising:
- a slipform mold, wherein the slipform mold is configured to form concrete, wherein the slipform mold comprises:
- a plurality of hydraulic vibrators, wherein the plurality of hydraulic vibrators are configured to vibrate in response to receiving hydraulic fluid;
- and
- one or more rheometers, wherein the one or more rheometers are configured to measure rheological parameters of the concrete;
- a hydraulic power supply comprising a hydraulic pump;
- a hydraulic manifold, wherein the hydraulic manifold is coupled between the hydraulic pump and the plurality of hydraulic vibrators;
- and
- a controller comprising one or more processors configured, via executable code, to:
- cause the hydraulic manifold to control actual flow rates of the hydraulic fluid from the hydraulic pump to the plurality of hydraulic vibrators thereby controlling actual frequencies of the plurality of hydraulic vibrators;
- and
- dynamically update at least one of target flow rates of the hydraulic fluid to the plurality of hydraulic vibrators or target frequencies of the plurality of hydraulic vibrators based on the rheological parameters.
