PROBLEM TO BE SOLVED: To provide a wet curing device for concrete that helps keeping the concrete surface wet easily in a column-like or wall-like concrete structure, without a concern over outflow of mortar content on the concrete surface even if water has run over the concrete surface, while allowing the device to be installed easily and furthermore enabling easy operation management; in addition, such a device conforms without a problem to a concrete structure built with an uneven surface and one with the superstructure and substructure of different dimensions.SOLUTION: A spray nozzle 15 is installed in the upper section, an excess water recovery gutter 18 is installed in the lower section, and the outer periphery is surrounded by a vinyl sheet 19. Furthermore, a water supply pipe 20 is installed in the upper section by hanging in a close proximity to a curing surface of a concrete surface 16, along with a water retention sheet 17 in a way that allows its lower edge get inside the excess water recovery gutter 18 underneath; then, water is supplied to the water retention sheet 17 from the water supply pipe 20 and is sprayed continuously from the spray nozzle 15, thereby maintaining the concrete surface in a wet condition. |
