策は不要となる。According to the present invention, the method for constructing a water-impermeable layer is as described above, and the following effects can be obtained. <B> A low water-permeable material is sprayed on the slope to form a low water-permeable layer. For this reason, construction is possible even on steep slopes. Moreover, it can be constructed with a simple device. <B> Spraying may be performed on the slope by a thickness necessary for the water-impermeable layer. Therefore, a poorly permeable layer can be easily and quickly constructed. Further, since there is no need to construct an extra water-impermeable layer, costs such as material costs, labor costs, and mechanical costs can be reduced. <C> The operation of spraying a water-impermeable material on a slope can be performed by a conventional slope concrete spraying technique. Therefore, a poorly permeable layer can be easily and quickly constructed with a small number of personnel. <D> It is possible to construct a water-impervious layer having high water-blocking performance simply by spraying a water-impervious material onto a slope to perform simple compaction. <E> By mixing the compaction by the spraying pressure and the binder, a poorly permeable layer having excellent erosion resistance against rainfall or the like can be constructed. For this reason, it is not necessary to take measures against rain on the sheet or the like after spraying.
