Abstract
A mobile vehicle mounted hydro demolition system comprising ultra-high pressurized water through a rotating nozzle water jet for cutting concrete, including a water supply, a vacuum blower, and a vacuum container that has offset with a dewatering bag so that incoming water can be pumped off as wastewater. A remote control gives an operator immediate adjustments of the rotational speed of the nozzle; the transverse traversing speed of the nozzle; the forward advancement of the vehicle; the number of traverses the head traverses before the vehicle advances its predetermined step; the pressure of the high-pressure pump; the amount of vacuum cfm's the blowers are producing; the steering of the vehicle; and the traversing distance of the rotating nozzle. By manipulating the above parameters the depth of removal is predictable and provides a consistent depth.
