Abstract:
1. A vehicle mounted apparatus for high-pressure fluid blasting to remove material from or otherwise treat a surface, the apparatus comprising: a high-pressure fluid supply connected to a nozzle assembly containing at least one nozzle, the nozzle assembly being supported for movement along a track mounted transversely on the vehicle and surrounded by a shroud having one or more suction inlet ports for the entry of air, fluid and released material, the shroud comprising an external housing, an insert and an inner housing, the external housing comprising a cylindrical structure with an open end and a closed end, the open end having an outwardly extending annular rim, the insert comprising a correspondingly shaped cylindrical structure with an open end and a closed end, the closed ends of the external housing and the insert both containing apertures that cooperate, once the insert and the external housing are engaged, to form an opening for the inner housing supporting the nozzle assembly, as well as apertures that cooperate to form one or more suction inlet ports; and a suction device for conveying an airflow and removed material through a conduit from the nozzle assembly to a treatment zone within the vehicle, the treatment zone having a separation means for accumulating removed material, a means for conveying airflow from the separation means to the suction device, and a means for conveying the removed material to a storage zone.
