Abstract
PURPOSE: To efficiently cut reinforced concrete by inserting nozzles into a cut groove, and injecting abrasive-mixed jets to the reinforced concrete from the nozzles.
CONSTITUTION: A mortar portion containing reinforcing materials such as reinforcing bars is cut by two abrasive-mixed liquid jets arranged at a proper interval, and the reinforcing bars and mortar are removed to form a wide groove 20. Two or more abrasive-mixed liquid jet nozzles 12, 12' having properly different discharge directions are inserted into the groove 20, and the mortar at the portion containing no reinforcing bars is cut by the jets injected from the nozzles 12, 12'.
