REPAIRING METHOD OF CONCRETE STRUCTURE USING THE STREAMLINE RUBBER NOZZLE

摘要

PURPOSE: A spray repairing method of concrete structure using streamline rubber nozzle is provided to use the uniformly spread item which is developed in streamline so that it can uniformly spray the cement mortar surface in maximally neighbored state, thereby repaired surface is clean and has excellent application characteristic. CONSTITUTION: A spray repairing method of concrete structure using streamline rubber nozzle manufacture a nozzle of uniformly sprayed item with a rubber material and enhances the spraying surface by manufacturing the nozzle spray ball(110) into streamline formed in long in one direction. It permits the cement mortar to be generally and uniformly sprayed in state of nozzle of the uniformly sprayed item to be neighbored to the concrete surface when working on uniformly spraying. The combining aperture is connected to the nozzle sprayed aperture on one side of the nozzle of the uniformly sprayed item. By combining the control plate(130) to be installed to the combining aperture, the hole length of the nozzle spray hole is comprised to be controlled according to the insertion level of control plate.
