摘要： The outer layer of a surface (11) is cut away by means of a high-pressure water jet by providing two parallel guides (12, 13; 51, 52) parallel to the surface, mounting a feed beam (22) between the guides, reciprocating a jet unit (33, 34) along the feed beam in cutting passes and moving the feed beam in steps along the guides in order to cut away the entire surface. The feed beam (22) is moved in steps between two cutting passes by providing two gripping jaws (40, 41), one fixed and one movable, for each guide (12, 13; 51, 52) and allowing one gripping jaw of each guide in turn to grip while the other is released, the movable gripping jaw (41) being displaced a predetermined length along the guide with the fixed gripping jaw in the gripping position.

摘要： The outer layer of concrete roadbeds and other exposed concrete surfaces erode and deteriorate, and, when being deteriorated, the outer layer must be removed and replaced by a new concrete layer. A tube (22) with a nozzle (23) at its end can be used for removing the concrete by a water jet. The tube is mounted on a carriage (20) that reciprocates along a feed beam (15). The tube is pivotable in two planes and hydraulic motors (rotary motors (21,24) and hydraulic cylinder (26)) are used for the movements of the tube and the carriage. The hydraulic motors are controlled by an electronic control unit (40) that controls distributing valves (42-44) for the hydraulic conduits (hoses) of the motors. Flow meters in the form of electric pulse transmitters (56,57,58) in the hydraulic conduits of the motors are coupled to the control unit (40). The pulse transmitters are positioned at a distance from the feed beam, and hydraulic lines but no electric lines lead to the feed beam.

摘要： A surface, e.g., a concrete surface, is worked by guiding a lance (23) which comprises a water jet mouthpiece (27) coupled to the high-pressure water over the surface in a working path and at the same oscillating the lance transversely to the working path. The oscillation is driven by an eccentric mechanism (30, 31) and has a stable eccentric position when the mechanism is rotated in the one direction and a stable eccentric position when it is rotated in the other direction. The two positions have a different eccentricity and impart different widths to the working. The working depth and the working width can be changed by changing the direction of rotation.

摘要： A machine for working of a surface, such as the removing of a damaged concrete layer, with a high-pressure water jet, comprises a carrier, such as a vehicle (11), that has a crosswise feed beam (12) carrying a cart (13) which in turn carries a lance (14) with a water nozzle (22) which is adjustable to give an angle of attack in the direction of movement of the cart and at the same time can oscillate in a plane transverse to the feed beam. When one adjusts the cutting depth by setting the speed along the feed beam, one always obtains an evenly cut surface in that the speed of the cart and the frequency of oscillation are coupled in a fixed ratio.
