WATER SPRAYER FOR CURING TUNNEL LINING CONCRETE AND CURING METHOD THEREOF

摘要

PURPOSE: A water sprayer and a curing method for tunnel lining concrete are provided to prevent a crack of a tunnel lining concrete and to ensure the required strength of the concrete by continuously and repeatedly spraying water on the surface of the concrete. CONSTITUTION: A water sprayer comprises a movement guiding portion(10) installed a pair of rails(11) in parallel; a water feeding portion(20) moved through the rails(11) by putting an arch pipe(21) to be connected with a water feeding hose(22); and a jetting portion(30) to jet water of the arch pipe(21) outward by connecting many injecting ports(31) when regular water pressure is added to the arch pipe(21). Water is sprayed on the surface of a lining concrete by continuously reciprocating the water feeding portion(20) and the water jetting portion(30) through the movement guiding portion(10).
