PROBLEM TO BE SOLVED: To provide a method for spraying and a spraying work which are applicable even to a natural ground with spring, which prevent the sprayed portion from peeling off, and which can grow vegetation.SOLUTION: In this method for spraying, a spraying material in which crushed ice is mixed is sprayed on a natural ground, and after the spraying material sprayed on the natural ground is hardened, the crushed ice is dissolved to form hollows in the portion of the natural ground where the crushed ice was positioned. Since the portion of the natural ground where the crushed ice dissolved was positioned is formed hollow, (1) the portion is high in permeability and allows spring or the like to quickly discharge therethrough, (2) the portion has approximately the same low strength as the natural ground, and can be recovered integrally with the peripheral natural grounds. (3) Since roots are fixed in the thousands of hollows, plants can be grown. (4) The portion is lightweight, and not peeled off by its own weight. |
