摘要：
A concrete cutting machine for remoting the upper layer of a concrete layer and free the outmost layer of reinforcement bars in the concrete, comprises a vehicle (11) with a transverse feed beam (22) that carries a carrier with two water jet nozzles (31, 32) mounted together on an elongated holder (30). The holder (30) is swingable about an axis transverse to the feed beam so as to provide for an angle of attack of the jets in both carrier moving directions when the carrier is reciprocated along the feed beam in concrete cutting sweeps. The holder (30) is also oscillated transverse to the feed beam. The angle between the jets is between (10 and 50) degrees as seen in the plane of oscillations and this provides for a freeing of the reinforcing rods whatever directions they have.
