Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a spray device capable of spraying stably over a long time while providing better strength developability, based on the fact that pipelines will not be clogged by the setting of quick-setting cement-concrete. SOLUTION: The spray device for the quick-setting cement-concrete comprises a pipeline A for transporting cement-concrete and a pipeline B for transporting a set accelerating agent. The crossing angle with which the axes of the lines A and B cross is 0 to 90 degrees.
