Kind Code:
A3
Abstract:
The invention relates to a device and method for high-pressure water jet blasting in closed channels (41), comprising a nozzle (13) having at least one nozzle opening (14) for generating a directed, bundled jet of a liquid jet medium, a nozzle mounting (11), a motorized carriage (1) for uniformly moving the nozzle mounting (11) through the channel (41) during the water jet treatment, a support device (31) by which the nozzle (13) is held in a position in the cross-section of the channel (41) even during advancing, a media supply (17) for supplying the nozzle (13) with a highly pressurized jet medium, and a control unit. The nozzle (13) is held pivotably by means of the nozzle mounting (11) such that the nozzle opening (14) can be pivoted about a pivot axis (15) with an angular range of 360º, and said pivoting and the driving of the carriage (1) can both be controlled by means of the control unit.
