VACUUM EXCAVATION SYSTEM AND METHOD FOR PREVENTING BLOCKAGES FROM FORMING THEREIN
Systems and methods for a vacuum excavator to prevent to formation of blockages know as spoil bridges are provided. The vacuum excavator includes a high vacuum blower that is coupled through a multi-stage airflow system that has a debris tank to which an excavation hose is coupled. A knuckle boom having two arm segments includes actuators to angularly position the arm segments, and hose roller assemblies that carry the excavation hose. The systems and methods control the angular position of the arm segments to control the flow curvature of the excavation hose from an excavation site to the debris tank in order to eliminate or reduce the occurrences of spoil bridges therein.
